Brigands of the Moon

(The Book of Gregg Haljan)
BEGINNING A FOUR-PART NOVEL

By Ray Cummings

Foreword by Ray Cummings

I HAVE been thinking that if, during one of those long winter evenings at Valley Forge, someone had placed in George Washington’s hands one of our present day best sellers, the illustrious Father of our Country would have read it with considerable emotion. I do not mean what we call a story of science, or fantasy—just a novel of action, adventure and romance. The sort of thing you and I like to read, but do not find amazing in any way at all.

But I fancy that George Washington would have found it amazing. Don’t you? It might picture, for instance, a factory girl at a sewing machine. George Washington would be amazed at a sewing machine. And the girl, journeying in the subway to and from her work! Stealing an opportunity to telephone her lover at the noon hour; going to the movies in the evening, or listening to a radio. And there might be a climax, perhaps, with the girl and the villain in a transcontinental railway Pullman, and the hero sending frantic telegrams, or telephoning the train, and then chasing it in his airplane.

George Washington would have found it amazing!

And I am wondering how you and I would feel if someone were to give us now a book of ordinary adventure of the sort which will be published a hundred and fifty years hence. I have been trying to imagine such a book and the nature of its contents.

LET us imagine it together. Suppose we walk down Fifth Avenue, a pleasant spring morning of May, 2080. Fifth Avenue, no doubt, will be there. I don’t know whether the New York Public Library will be there or not. We’ll assume that it is, and that it has some sort of books, printed, or in whatever fashion you care to imagine.

The young man library attendant is surprised at our curiously antiquated aspect. We look as though we were dressed for some historical costume ball. We talk old-fashioned English, like actors in an historical play of the 1930 period.

But we get the book. The attendant assures us it is a good average story of action and adventure. Nothing remarkable, but he read it himself, and found it interesting.

We thank him and take the book. But we find that the language in which it is written is too strange for comfortable reading. And it names so many extraordinary things so casually! As though we knew all about them, which we certainly do not!

So we take it to the kind-hearted librarian in the language division. He modifies it to old-fashioned English of 1930, and he puts occasional footnotes to help explain some of the things we might not understand. Why he should bother to do this for us I don’t know; but let us assume that he does.

And now we take the book home–in the pneumatic tube, or aerial moving sidewalk, or airship, or whatever it is we take to get home.

And now that we are home, let’s read the book. It ought to be interesting.

CHAPTER I
Tells of the Grantline Moon Expedition and of the Mysterious Martian Who Followed Us in the City Corridor

ONE may write about oneself and still not be an egoist. Or so, at least, they tell me. My narrative went broadcast with a fair success. It was pantomimed and the public flashed me a reasonable approval. And so my disc publishers have suggested that I record it in more permanent form.

I introduce myself, begging grace that I intrude upon your busy minutes, with my only excuse that perhaps I may amuse you. For what the commercial sellers of my pictured version were pleased to blare as my handsome face, I ask your indulgence. My feminine audience of the pantomimes was undoubtedly graciously pleased at my personality and physical aspect. That I am “tall as a Viking of old”—and “handsome as a young Norse God”—is very pretty talk in the selling of my product. But I deplore its intrusion into the personality of this, my recorded narrative. And so now, for preface, to all my audience I do give earnest assurance that Gregg Haljan is no conceited zebra, handsomely striped by nature, and proud of it. Not so. I am, I do beg you to believe, a very humble fellow, striving for your approval, hoping only to entertain you.

My introduction: My name, Gregg Haljan. My age, twenty-five years. I was, at the time my narrative begins, Third Officer on the Space-Ship Planetara. Our line was newly established; in 2070, to be exact, following the modern improvements of the Martel Magnetic Levitation.¹

As early as 1910 it was discovered that an object magnetized under certain conditions was subject to a loss of weight, its gravity partially nullified. The Martel discovery undoubtedly followed that method.

OUR ship, whose home port was Great-New York, carried mail and passenger traffic to and from both Venus and Mars. Of astronomical necessity, our flights were irregular. This spring, with the two other planets both close to the earth, we were making two complete round trips. We had just arrived in Great-New York, this May evening, from Grebhar, Venus Free State. With only five hours in port here, we were departing the same night at the zero hour for Ferrok-Shahn, capital of the Martian Union.

We were no sooner at the landing stage than I found a code-flash summoning Dan Dean and me to Divisional Detective Headquarters. Dan “Snap” Dean was one of my closest friends. He was radio-helio operator of the Planetara. A small, wiry, red-headed chap, with a quick, ready laugh and a wit that made everyone like him.

The summons to Detective-Colonel Halsey’s office surprised us. Snap eyed me.

“You haven’t been opening any treasury vaults, have you, Gregg?”

“He wants you, also,” I retorted.

He laughed. “Well, he can roar at me like a traffic switchman and my private life will remain my own.”

We could not think why we should be wanted. It was the darkness of mid-evening when we left the Planetara for Halsey’s office. It was not a long trip. We went direct in the upper monorail, descending into the subterranean city at Park-Circle 30.

WE had never been to Halsey’s office before. We found it to be a gloomy, vaultlike place in one of the deepest corridors. The door lifted.

“Gregg Haljan and Daniel Dean.”

The guard stood aside. “Come in.”

I own that my heart was unduly thumping as we entered. The door dropped behind us. It was a small blue-lit apartment—a steel-lined room like a vault.

Colonel Halsey sat at his desk. And the big, heavy-set, florid Captain Carter—our commander of the Planetara—was here. That surprised us: we had not seen him leave the ship.

Halsey smiled at us gravely. Captain Carter said, “Sit down, lads.”

We took the seats. There was an alarming solemnity about this. If I had been guilty of anything that I could think of, it would have been frightening. But Halsey’s first words reassured me.

“It’s about the Grantline Moon Expedition. In spite of our secrecy, the news has gotten out. We want to know how. Can you tell us?”

Captain Carter’s huge bulk—he was about as tall as I am—towered over us as we sat before Halsey’s desk. “If you lads have told anyone—said anything—let slip the slightest hint about it—”

Snap smiled with relief; but he turned solemn at once. “I haven’t. Not a word!”

“Nor have I,” I declared.

THE Grantline Moon Expedition! We had not thought of that as a reason for this summons. Johnny Grantline was a close friend to us both. He had organized an exploring expedition to the Moon. Uninhabited, with its bleak, forbidding, airless, waterless surface, the Moon—even though so close to the Earth—was seldom visited. No regular ship ever stopped there. A few exploring parties of recent years had come to grief.

But there was a persistent rumor that upon the Moon, mineral riches of fabulous wealth were awaiting discovery. The thing had already caused some interplanetary complications. The aggressive Martians would be only too glad to explore the Moon. But the U.S.W.² definitely warned them away. The Moon was World Territory, we announced, and we would protect it as such.

“United States of the World,” which came into being in 2057 upon the centenary of the Yellow War.

The threatened conflict between the Earth and Mars had come to nothing. There was, this year of 2079, a thorough amity between all three of the inhabited planets. It still holds, and I pray that it may always hold.

There was, nevertheless, a realization by our government, that whatever riches might be upon the Moon should be seized at once and held by some reputable Earth Company. And when Johnny Grantline applied, with his father’s wealth and his own scientific record of attainment, the government was only too glad to grant him its writ.

THE Grantline Expedition had started six months ago. The Martian government had acquiesced in our ultimatum, yet brigands have been known to be financed under cover of a governmental disavowal. And so the expedition was kept secret.

My words need give no offense to any Martian who comes upon them. I refer to the history of our earth only. The Grantline Expedition was on the Moon now. No word had come from it. One could not flash helios even in code without letting all the universe know that explorers were on the Moon. And why they were there, anyone could easily guess.

And now Colonel Halsey was telling us that the news was abroad! Captain Carter eyed us closely; his flashing eyes under the white bushy brows would pry a secret from anyone.

“You’re sure? A girl of Venus, perhaps, with her cursed, seductive lure! A chance word, with you lads befuddled by alcolite?”

We assured him we had been careful. By the heavens, I know that I had been. Not a whisper, even to Snap, of the name Grantline in six months or more.

Captain Carter added abruptly, “We’re insulated here, Halsey?”

“Yes, talk as freely as you like. An eavesdropping ray will never get into these walls.”

THEY questioned us. They were satisfied at last that, though the secret had escaped, we had not done it. Hearing it discussed, it occurred to me to wonder why Carter was concerned. I was not aware that he knew of Grantline’s venture. I learned now the reason why the Planetara, upon each of her voyages, had managed to pass fairly close to the Moon. It had been arranged with Grantline that if he wanted help or had any important message, he was to flash it locally to our passing ship. And this Snap knew, and had never mentioned it, even to me.

Halsey was saying, “Well, we can’t blame you, but the secret is out.”

Snap and I regarded each other. What could anyone do? What would anyone dare do?

Captain Carter said abruptly, “Look here, lads, this is my chance now to talk plainly to you. Outside, anywhere outside these walls, an eavesdropping ray may be upon us. You know that? One may never even dare whisper since that accursed ray was developed.”

Snap opened his mouth to speak but decided against it. My heart was pounding.

Captain Carter went on, “I know I can trust you two more than anyone else under me on the Planetara—”

“What do you mean by that?” I demanded. “What—”

He interrupted me. “Nothing at all but what I say.”

HALSEY smiled grimly. “What he means, Haljan, is that things are not always what they seem these days. One cannot always tell a friend from an enemy. The Planetara is a public vessel. You have—how many is it, Carter?—thirty or forty passengers this trip to-night?”

“Thirty-eight,” said Carter.

“There are thirty-eight people listed for the flight to Ferrok-Shahn to-night,” Halsey said slowly. “And some may not be what they seem.” He raised his thin dark hand. “We have information—” He paused. “I confess, we know almost nothing—hardly more than enough to alarm us.”

Captain Carter interjected, “I want you and Dean to be on your guard. Once on the Planetara it is difficult for us to talk openly, but be watchful. I will arrange for us to be doubly armed.”

Vague, perturbing words! Halsey said, “They tell me George Prince is listed for the voyage. I am suggesting, Haljan, that you keep your eye especially upon him. Your duties on the Planetara leave you comparatively free, don’t they?”

“Yes,” I agreed. With the first and second officers on duty, and the captain aboard, my routine was more or less that of an understudy.

I said, “George Prince! Who is he?”

“A mechanical engineer,” said Halsey. “An under-official of the Earth Federated Radium Corporation. But he associates with bad companions—particularly Martians.”

I had never heard of this George Prince, though I was familiar with the Federated Radium Corporation, of course. A semi-government trust, which controlled virtually the entire Earth supply of radium.

“He was in the Automotive Department,” Carter put in. “You’ve heard of the Federated Radium Motor?”

WE had, of course. A recent Earth invention which promised to revolutionize the automotive industry. An engine of a new type, using radium as its fuel.

Snap demanded, “What in the stars has this got to do with Johnny Grantline?”

“Much,” said Halsey quietly, “or perhaps nothing. But George Prince some years ago mixed in rather unethical transactions. We had him in custody once. He is known now as unusually friendly with several Martians in New York of bad reputation.”

“Well—” began Snap.

“What you don’t know,” Halsey went on quietly, “is that Grantline expects to find radium on the Moon.”

We gasped.

“Exactly,” said Halsey. “The ill-fated Ballon Expedition thought they had found it on the Moon some years ago. A new type of ore, as rich in radium as our gold-bearing sands are rich in gold. Ballon’s first samples gave uranium atoms with a fair representation of ionium and thorium. A richly radio-active ore. A lode of the pure radium is there somewhere, without doubt.”

HE added vehemently, “Do you understand now why we should be suspicious of this George Prince? He has a criminal record. He has a thorough technical knowledge of radium ores. He associates with Martians of bad reputation. A large Martian Company has recently developed a radium engine to compete with our Earth motor. You know that? You know that there is very little radium available on Mars, and our government will not allow our own radium supply to be exported. That Martian Company needs radium. It will do anything to get radium. What do you suppose it would pay for a few tons of really rich radio-active ore—such as Grantline may have found on the Moon?”

“But,” I objected, “that is a reputable Martian company. It’s backed by the government of the Martian Union. The government of Mars would not dare—”

“Of course not!” Captain Carter exclaimed sardonically. “Not openly! But if Martian brigands had a supply of radium—I don’t imagine where it came from would make much difference. That Martian Company would buy it.”

Halsey added, “And George Prince, my agents inform me, seems to know that Grantline is on the Moon. Put it all together, lads. Little sparks show the hidden current.

“More than that: George Prince knows that we have arranged to have the Planetara stop at the Moon and bring back Grantline’s radium-ore. This is your last voyage this year. You’ll hear from Grantline this time, we’re convinced. He’ll probably give you the signal as you pass the Moon on your way out. Coming back, you’ll stop at the Moon and transport whatever radium-ore Grantline has ready. The Grantline Flyer is too small for ore transportation.”

HALSEY'S voice turned grimly sarcastic. “Doesn’t it seem queer that George Prince and a few of his Martian friends happen to be listed as passengers for this voyage?”

In the silence that followed, Snap and I regarded each other. Halsey added abruptly,

“We had George Prince typed that time we arrested him four years ago. I’ll show him to you.”

He snapped open an alcove, and said to his waiting attendant, “Get me the type of George Prince.”

The disc in a moment came through the pneumatic. Halsey, smiling wryly, adjusted it.

“A nice looking fellow. Nicely spoken. Though at the time we made this he was somewhat annoyed, naturally. He is older now. Twenty-nine, to be exact. Here he is.”

The image glowed on the grids before us. His name, George Prince, in letters illumined upon his forehead, showed for a moment and then faded. He stood smiling sourly before us as he repeated the official formula:

“My name is George Prince. I was born in Great-New York City twenty-five years ago.”

I GAZED at this life-size, moving image of George Prince. He stood somber in the black detention uniform. A dark, almost a girlishly handsome fellow, well below medium height—the rod beside him showed five feet four inches. Slim and slight. Long, wavy black hair, falling about his ears. A pale, clean-cut, really handsome face, almost beardless. I regarded it closely. A face that would have been femininely beautiful without its masculine touch of heavy black brows and firmly set jaw. His voice as he spoke was low and soft; but at the end, with the concluding words, “I am innocent!” it flashed into strong masculinity. His eyes, shaded with long, girlish black lashes, by chance met mine. “I am innocent.” His curving sensuous lips drew down into a grim sneer....

The type faded at its end. Halsey replaced the disc in its box and waved the attendant away. “Thank you.”

He turned back to Snap and me. “Well, there he is. We have nothing tangible against him now. But I’ll say this: he’s a clever fellow, one to be afraid of. I would not blare it from the newscasters’ microphone, but if he is hatching any plot, he has been too clever for my agents.”

We talked for another half-hour, and then Captain Carter dismissed us. We left Halsey’s office with Carter’s final words ringing in our ears. “Whatever comes, lads, remember I trust you....”

SNAP and I decided to walk a portion of the way back to the ship. It was barely more than a mile through this subterranean corridor to where we could get the vertical lift direct to the landing stage.

We started off on the lower level. Once outside the insulation of Halsey’s office we did not dare talk of this thing. Not only electrical ears, but every possible eavesdropping device might be upon us. The corridor was two hundred feet or more below the ground level. At this hour of the night this business section was comparatively deserted. The through tube sounded over our heads with the passing of its occasional trains. The ventilators buzzed and whirred. At the cross intersections, the traffic directors dozed at their posts. It was hot and sticky down here, and gloomy with the daylight globes extinguished, and only the night lights to give a dim illumination. The stores and office arcades were all closed and deserted; only an occasional night-light burning behind their windows.

Our footfalls echoed on the metal grids as we hurried along.

“Nice evening,” said Snap awkwardly.

“Yes,” I said, “isn’t it?”

I felt oppressed. As though prying eyes and ears were here. We walked for a time in silence, each of us busy with memory of what had transpired in Halsey’s office.

Suddenly Snap gripped me. “What’s that?”

“Where?” I whispered.

WE stopped at a corner. An entryway was here. Snap pulled me into it. I could feel him quivering with excitement.

“What is it?” I demanded in a whisper.

“We’re being followed. Did you hear anything?”

“No!” Yet I thought now I could hear something. Vague footfalls. A rustling. And a microscopic electrical whine, as though some device were near us.

Snap was fumbling in his pocket. “Wait, I’ve got a pair of low-scale phones.”

He put the little grids against his ears. I could hear the sharp intake of his breath. Then he seized me, pulled me down to the metal floor of the entryway.

“Back, Gregg! Get back!” I could barely hear his whisper. We crouched as far back into the doorway as we could get. I was armed. My official permit for the carrying of the pencil heat-ray allowed me to have it always with me. I drew it now. But there was nothing to shoot at. I felt Snap clamping the grids on my ears. And now I heard something! An intensification of the vague footsteps I had thought I heard before.

There was something following us! Something out in the corridor there now! A street light was nearby. The corridor was dim, but plainly visible; and to my sight it was empty. But there was something there. Something invisible! I could hear it moving. Creeping towards us. I pulled the grids off my ears.

Snap murmured, “You’ve got a local phone.”

“Yes! I’ll get them to give us the street glare!”

I PRESSED the danger signal, giving our location to the nearest operator. In a second or two we got the light. The street in all this neighborhood burst into a brilliant actinic glare. The thing menacing us was revealed! A figure in a black cloak, crouching thirty feet away across the corridor.

Snap was on his feet. His voice rang shrilly, “There it is! Give it a shot, Gregg!”

Snap was unarmed, but he flung his hands out menacingly. The figure, which may perhaps not have been aware of our city safeguard, was taken wholly by surprise. A human figure. Seven feet tall, at the least, and therefore, I judged, doubtless a Martian man. The black cloak covered his head. He took a step toward us, hesitated, and then turned in confusion.

Snap’s shrill voice was bringing help. The whine of a street guard’s alarm whistle nearby sounded. The figure was making off! My pencil-ray was in my hand and I pressed its switch. The tiny heat-ray stabbed through the glare, but I missed. The figure stumbled, but did not fall. I saw a bare gray arm come from the cloak, flung up to maintain its balance. Or perhaps my pencil-ray of heat had seared the arm. The gray-skinned arm of a Martian.

Snap was shouting, “Give him another!” But the figure passed beyond the actinic glare and vanished.

We were detained in the turmoil of the corridor for ten minutes or more with official explanations. Then a message from Halsey released us. The Martian who had been following us in his invisible cloak was never caught.

We escaped from the crowd at last and made our way back to the Planetara, where the passengers were already assembling for the outward Martian voyage.

CHAPTER II
“A Fleeting Glance—”

I STOOD on the turret-balcony of the Planetara with Captain Carter and Dr. Frank, the ship surgeon, watching the arriving passengers. It was close to the zero hour: the level of the stage was a turmoil of confusion. The escalators, with the last of the freight aboard, were folded back. But the stage was jammed with the incoming passenger baggage: the interplanetary customs and tax officials with their X-ray and Zed-ray paraphernalia and the passengers themselves, lined up for the export inspection.

At this height, the city lights lay spread in a glare of blue and yellow beneath us. The individual local planes came dropping like birds to our stage. Thirty-eight passengers for this flight to Mars, but that accursed desire of every friend and relative to speed the departing voyager brought a hundred or more extra people to crowd our girders and bring added difficulty to everybody.

Carter was too absorbed in his duties to stay with us long. But here in the turret Dr. Frank and I found ourselves at the moment with nothing much to do but watch.

“Think we’ll get away on time, Gregg?”

“No,” I said. “And this of all voyages—”

I checked myself, with thumping heart. My thoughts were so full of what Halsey and Carter had told us that it was difficult to rein my tongue. Yet here in the turret, unguarded by insulation, I could say nothing. Nor would I have dared mention the Grantline Moon Expedition to Dr. Frank. I wondered what he knew of this affair. Perhaps as much as I—perhaps nothing.

HE was a thin, dark, rather smallish man of fifty, this ship’s surgeon, trim in his blue and white uniform. I knew him well: we had made several flights together. An American—I fancy of Jewish ancestry. A likable man, and a skillful doctor and surgeon. He and I had always been good friends.

“Crowded,” he said. “Johnson says thirty-eight. I hope they’re experienced travelers. This pressure sickness is a rotten nuisance—keeps me dashing around all night assuring frightened women they’re not going to die. Last voyage, coming out of the Venus atmosphere—”

He plunged into a lugubrious account of his troubles with space-sick voyagers. But I was in no mood to listen. My gaze was down on the spider incline, up which, over the bend of the ship’s sleek, silvery body, the passengers and their friends were coming in little groups. The upper deck was already jammed with them.

The Planetara, as flyers go, was not a large vessel. Cylindrical of body, forty feet maximum beam, and two hundred and seventy-five feet in overall length. The passenger superstructure—no more than a hundred feet long—was set amidships. A narrow deck, metallic-enclosed, and with large bulls-eye windows, encircled the superstructure. Some of the cabins opened directly onto the deck. Others had doors to the interior corridors. There were half a dozen small but luxurious public rooms.

THE rest of the vessel was given to freight storage and the mechanism and control compartments. Forward of the passenger structure the deck level continued under the cylindrical dome-roof to the bow. The forward watch-tower observatory was here; officers’ cabins; Captain Carter’s navigating rooms and Dr. Frank’s office. Similarly, under the stern-dome, was the stern watch-tower and a series of power compartments.

Above the superstructure a confusion of spider bridges, ladders and balconies were laced like a metal network. The turret in which Dr. Frank and I now stood was perched here. Fifty feet away, like a bird’s nest, Snap’s instrument room stood clinging to the metal bridge. The dome-roof, with the glassite windows rolled back now, rose in a mound-peak to cover this highest middle portion of the vessel.

Below, in the main hull, blue-lit metal corridors ran the entire length of the ship. Freight storage compartments; gravity control rooms; the air renewal systems; heater and ventilators and pressure mechanisms—all were located there. And the kitchens, stewards’ compartments, and the living quarters of the crew. We carried a crew of sixteen, this voyage, exclusive of the navigating officers, and the purser, Snap Dean, and Dr. Frank.

THE passengers coming aboard seemed a fair representation of what we usually had for the outward voyage to Ferrok-Shahn. Most were Earth people—and returning Martians. Dr. Frank pointed out one. A huge Martian in a gray cloak. A seven-foot fellow.

“His name is Set Miko,” Dr. Frank remarked. “Ever heard of him?”

“No,” I said. “Should I?”

“Well—” The doctor suddenly checked himself, as though he were sorry he had spoken.

“I never heard of him,” I repeated slowly.

An awkward silence fell suddenly between us.

There were a few Venus passengers. I saw one of them presently coming up the incline, and recognized her. A girl traveling alone. We had brought her from Grebhar, last voyage but one. I remembered her. An alluring sort of girl, as most of them are. Her name was Venza. She spoke English well. A singer and dancer who had been imported to Great-New York to fill some theatrical engagement. She’d made quite a hit on the Great White Way.

She came up the incline, with the carrier ahead of her. Gazing up, she saw Dr. Frank and me at the turret window and waved her white arm in greeting. And flashed us a smile.

Dr. Frank laughed. “By the gods of the airways, there’s Alta Venza! You saw that look, Gregg? That was for me, not you.”

“Reasonable enough,” I retorted. “But I doubt it—the Venza was nothing if not impartial.”

I WONDERED what could be taking Venza now to Mars. I was glad to see her. She was diverting. Educated. Well-traveled. Spoke English with a colloquial, theatrical manner more characteristic of Great-New York than of Venus. And for all her light banter, I would rather put my trust in her than any Venus girl I had ever met.

The hum of the departing siren was sounding. Friends and relatives of the passengers were crowding the exit incline. The deck was clearing. I had not seen George Prince come aboard. And then I thought I saw him down on the landing stage, just arrived from a private tube-car. A small, slight figure. The customs men were around him: I could only see his head and shoulders. Pale, girlishly handsome face; long, black hair to the base of his neck. He was bareheaded, with the hood of his traveling-cloak pushed back.

I stared, and I saw that Dr. Frank was also gazing down. But neither of us spoke.

Then I said upon impulse, “Suppose we go down to the deck, Doctor?”

He acquiesced. We descended to the lower room of the turret and clambered down the spider ladder to the upper deck-level. The head of the arriving incline was near us. Preceded by two carriers who were littered with hand-baggage, George Prince was coming up the incline. He was closer now. I recognized him from the type we had seen in Halsey’s office.

AND then, with a shock, I saw it was not so. This was a girl coming aboard. An arch-light over the incline showed her clearly when she was half way up. A girl with her hood pushed back; her face framed in thick black hair. I saw now it was not a man’s cut of hair; but long braids coiled up under the dangling hood.

Dr. Frank must have remarked my amazed expression.

“Little beauty, isn’t she?”

“Who is she?”

We were standing back against the wall of the superstructure. A passenger was near us—the Martian whom Dr. Frank had called Miko. He was loitering here, quite evidently watching this girl come aboard. But as I glanced at him he looked away and casually sauntered off.

The girl came up and reached the deck. “I am in A 22,” she told the carrier. “My brother came aboard two hours ago.”

Dr. Frank answered my whisper. “That’s Anita Prince.”

She was passing quite close to us on the deck, following the carrier, when she stumbled and very nearly fell. I was nearest to her. I leaped forward and caught her as she went down.

“Oh!” she cried.

With my arm about her, I raised her up and set her upon her feet again. She had twisted her ankle. She balanced herself upon it. The pain of it eased up in a moment.

“I’m—all right—thank you!”

IN the dimness of the blue-lit deck, I met her eyes. I was holding her with my encircling arm. She was small and soft against me. Her face, framed in the thick, black hair, smiled up at me. Small, oval face—beautiful—yet firm of chin, and stamped with the mark of its own individuality. No empty-headed beauty, this.

“I’m all right, thank you very much—”

I became conscious that I had not released her. I felt her hands pushing at me. And then it seemed that for an instant she yielded and was clinging. And I met her startled, upflung gaze. Eyes like a purple night with the sheen of misty starlight in them.

I heard myself murmuring, “I beg your pardon. Yes, of course!” I released her.

She thanked me again and followed the carrier along the deck. She was limping slightly from the twisted ankle.

An instant, while she had clung to me—and I had held her. A brief flash of something, from her eyes to mine—from mine back to hers. The poets write that love can be born of such a glance. The first meeting, across all the barriers of which love springs unsought, unbidden—defiant, sometimes. And the troubadours of old would sing: “A fleeting glance; a touch; two wildly beating hearts—and love was born.”

I think, with Anita and me, it must have been like that....

I stood gazing after her, unconscious of Dr. Frank, who was watching me with his humorous smile. And presently, no more than a quarter beyond the zero hour, the Planetara got away. With the dome-windows battened tightly, we lifted from the landing stage and soared over the glowing city. The phosphorescence of the electronic tubes was like a comet’s tail behind us as we slid upward.

At the trinight hour the heat of our atmospheric passage was over. The passengers had all retired. The ship was quiet, with empty decks and dim, silent corridors. Vibrationless, with the electronic engines cut off and only the hum of the Martel magnetizers to break the unnatural stillness. We were well beyond the earth’s atmosphere, heading out in the cone-path of the earth’s shadow, in the direction of the moon.

CHAPTER III
In the Helio-room

At six A. M., earth Eastern time, which we were still carrying, Snap Dean and I were alone in his instrument room, perched in the network over the Planetara’s deck. The bulge of the dome enclosed us; it rounded like a great observatory window some twenty feet above the ceiling of this little metal cubby-hole.

The Planetara was still in the earth’s shadow. The firmament—black interstellar space with its blazing white, red and yellow stars—lay spread around us. The moon, with nearly all its disc illumined, hung, a great silver ball, over our bow quarter. Behind it, to one side, Mars floated like the red tip of a smoldering cigarillo in the blackness. The earth, behind our stern, was dimly, redly visible—a giant sphere, etched with the configurations of its oceans and continents. Upon one limb a touch of the sunlight hung on the mountain-tops with a crescent red-yellow sheen.

And then we plunged from the cone-shadow. The sun, with the leaping Corona, burst through the blackness behind us. The earth lighted into a huge, thin crescent with hooked cusps.

To Snap and me, the glories of the heavens were too familiar to be remarked. And upon this voyage particularly we were in no mood to consider them. I had been in the helio-room several hours. When the Planetara started, and my few routine duties were over, I could think of nothing save Halsey’s and Carter’s admonition: “Be on your guard. And particularly—watch George Prince.”

I had not seen George Prince. But I had seen his sister, whom Carter and Halsey had not bothered to mention. My heart was still pounding with the memory....

When the passengers had retired and the ship quieted, I prowled through the passenger corridors. This was about the trinight hour.³ Hot as the corridors of hell, with our hull and the glassite dome seething with the friction of our atmospheric flight. But the refrigerators mitigated that; the ventilators blasted cold air from the renewers into every corner of the vessel. Within an hour or two, with the cold of space striking us, it was hot air that was needed.

3: Trinight Hour, i.e., 3 A. M.

Dr. Frank evidently was having little trouble with pressure-sick passengers⁴—the Planetara’s equalizers were fairly efficient. I did not encounter Dr. Frank. I prowled through the silent metal lounges and passages. I went to the door of A 22. It was on the deck-level, in a tiny transverse passage just off the main lounging room. Its name-grid glowed with the letters: “Anita Prince.” I stood in my short white trousers and white silk shirt, like a cabin steward gawping. Anita Prince! I had never heard the name until this night. But there was magic music in it now, as I murmured it to myself. Anita Prince....

4: Pressure sickness. Caused by the difficulty of maintaining a constantly normal air pressure within the vessel owing to the sudden, extreme changes from heat to cold.

She was here, doubtless asleep, behind this small metal door. It seemed as though that little oval grid were the gateway to a fairyland of my dreams.

I turned away. And thought of the Grantline Moon Expedition stabbed at me. George Prince—Anita’s brother—he whom I had been told to watch. This renegade—associate of dubious Martians, plotting God knows what.

I saw, upon the adjoining door, “A 20, George Prince.” I listened. In the humming stillness of the ship’s interior there was no sound from these cabins. A 20 was without windows, I knew. But Anita’s room had a window and a door which gave upon the deck. I went through the lounge, out its arch, and walked the deck length. The deck door and window of A 22 were closed and dark.

The ten-foot-wide deck was dim with white starlight from the side ports. Chairs were here, but they were all empty. From the bow windows of the arching dome a flood of moonlight threw long, slanting shadows down the deck. At the corner where the superstructure ended, I thought I saw a figure lurking as though watching me. I went that way, but it vanished.

I turned the corner, went the width of the ship to the other side. There was no one in sight save the observer on his spider bridge, high in the bow network, and the second officer, on duty on the turret balcony almost directly over me.

As I stood and listened, I suddenly heard footsteps. From the direction of the bow a figure came. Purser Johnson.

He greeted me. “Cooling off, Gregg?”

“Yes,” I said.

He went past me and turned into the smoking room door nearby.

I stood a moment at one of the deck windows, gazing at the stars; and for no reason at all I realized I was tense. Johnson was a great one for his regular sleep—it was wholly unlike him to be roaming about the ship at such an hour. Had he been watching me? I told myself it was nonsense. I was suspicious of everyone, everything, this voyage.

I heard another step. Captain Carter appeared from his chart-room which stood in the center of the narrowing open deck space near the bow. I joined him at once.

“Who was that?” he half-whispered.

“Johnson.”

“Oh, yes.” He fumbled in his uniform; his gaze swept the moonlit deck. “Gregg—take this.” He handed me a small metal box. I stuffed it at once into my shirt.

“An insulator,” he added, swiftly. “Snap is in his office. Take it to him, Gregg. Stay with him—you’ll have a measure of security—and you can help him to make the photographs.” He was barely whispering. “I won’t be with you—no use making it look as though we were doing anything unusual. If your graphs show anything—or if Snap picks up any message—bring it to me.” He added aloud, “Well, it will be cool enough presently, Gregg.”

He sauntered away toward his chart-room.

“By heavens, what a relief!” Snap murmured as the current went on. We had wired his cubby with the insulator; within its barrage we could at last talk with a degree of freedom.

“You’ve seen George Prince, Gregg?”

“No. He’s assigned A 20. But I saw his sister. Snap, no one ever mentioned—”

Snap had heard of her, but he hadn’t known that she was listed for this voyage. “A real beauty, so I’ve heard. Accursed shame for a decent girl to have a brother like that.”

I could agree with him there, but I made no comment.

IT was now 6 A. M. Snap had been busy all night with routine cosmo-radios from the earth, following our departure. He had a pile of them beside him. Many were for the passengers; but anything that savored of a code was barred.

“Nothing queer looking?” I suggested.

“No. Not a thing.”

We were at this time no more than some sixty-five thousand miles from the moon’s surface. The Planetara presently would swing upon her direct course for Mars. There was nothing which could cause passenger comment in this close passing of the moon; normally we used the satellite’s attraction to give us additional starting speed.

It was now or never that a message would come from Grantline. He was supposed to be upon this earthward side of the moon. While Snap had rushed through with his routine, I had searched the moon surface with our glass, as I knew Carter was searching it—and also the observer in his tower, very possibly.

But there was nothing. Copernicus and Kepler lay in full sunlight. The heights of the lunar mountains, the depths of the barren, empty seas were etched black and white, clear and clean. Grim, forbidding desolation, this unchanging moon! In romance, moonlight may shimmer and sparkle to light a lover’s smile; but the reality of the moon is cold and bleak. There was nothing to show my prying eyes where the intrepid Grantline might be.

“Nothing at all, Snap.”

And Snap’s helio mirrors, attuned for an hour now to pick up the faintest signal, were motionless.

“If he has concentrated any appreciable amount of radio-active ore,” said Snap, “we should get an impulse from its Gamma rays.”

BUT our receiving shield was dark, untouched. We tried taking hydrogen photographic impressions of the visible moon surface. A sequence of them, with stereoscopic lenses, forty-eight to the second. Our mirror-grid gave the magnified images; the spectro-heliograph, with its wave-length selection, pictured the mountain-levels, and slowly descended into the deepest seas.

There was nothing.

Yet in those moon caverns—a million million recesses amid the crags of that tumbled, barren surface—the pin-point of movement which might have been Grantline’s expedition could so easily be hiding! Could he have the ore insulated, fearing its Gamma rays would betray its presence to hostile watchers?

Or might disaster have come to him? Or he might not be upon this hemisphere of the moon at all....

My imagination, sharpened by fancy of a lurking menace which seemed everywhere about the Planetara this voyage, ran rife with fears for Johnny Grantline. He had promised to communicate this voyage. It was now, or perhaps never.

Six-thirty came and passed. We were well beyond the earth’s shadow now. The firmament blazed with its vivid glories; the sun behind us was a ball of yellow-red leaping flames. The earth hung, opened to a huge, dull-red half-sphere.

WE were within some forty thousand miles of the moon. Giant white ball—all of its disc visible to the naked eye. It poised over the bow, and presently, as the Planetara swung upon her course for Mars, it shifted sidewise. The light of it glared white and dazzling in our tiny side windows.

Snap, with his habitual red celluloid eyeshade shoved high on his forehead, worked over our instruments.

“Gregg!”

The receiving shield was glowing a trifle! Gamma rays were bombarding it! It glowed, gleamed phosphorescent, and the audible recorder began sounding its tiny tinkling murmurs.

Gamma rays! Snap sprang to the dials. The direction and strength were soon obvious. A richly radio-active ore body, of considerable size, was concentrated upon this hemisphere of the moon! It was unmistakable.

“He’s got it, Gregg! He’s—”

The tiny helio mirrors began quivering. Snap exclaimed triumphantly, “Here he comes! By God, the message at last! Bar off that light!”

I FLUNG on the absorbers. The moonlight bathing the little room went into them and darkness sprang around us. Snap fumbled at his instrument board. Actinic light showed dimly in the quivering, thumbnail mirrors. Two of them. They hung poised on their cobweb wires, infinitely sensitive to the infra-red light-rays Grantline was sending from the moon. The mirrors in a moment began swinging. On the scale across the room the actinic beams from them were magnified into sweeps of light.

The message!

Snap spelled it out, decoded it.

“Success! Stop for ore on your return voyage. Will give you our location later. Success beyond wildest hopes—”

The mirrors hung motionless. The shield, where the Gamma rays were bombarding, went suddenly dark.

Snap murmured, “That’s all. He’s got the ore! ‘Success beyond wildest hopes.’ That must mean an enormous quantity of it available!”

We were sitting in darkness, and abruptly I became aware that across our open window, where the insulation barrage was flung, the air was faintly hissing. An interference there! I saw a tiny swirl of purple sparks. Someone—some hostile ray from the deck beneath us, or from the spider bridge that led to our little room—someone out there trying to pry in!

Snap impulsively reached for the absorbers to let in the outside light—it was all darkness to us outside. But I checked him.

“Wait!” I cut off our barrage, opened our door and stepped to the narrow metal bridge.

“Wait, Snap! You stay there.” I added aloud, “Well, Snap, I’m going to bed. Glad you’ve cleaned up that batch of work.”

I BANGED the door upon him. The lacework of metal bridges and ladders seemed empty. I gazed up to the dome, and forward and aft. Twenty feet beneath me was the metal roof of the cabin superstructure. Below it, both sides of the deck showed. All patched with moonlight.

No one visible down there. I descended a ladder. The deck was empty. But in the silence something was moving! Footsteps moving away from me down the deck! I followed; and suddenly I was running. Chasing something I could hear, but could not see. It turned into the smoking room.

I burst in. And a real sound smothered the phantom. Johnson the purser was sitting here alone in the dimness. He was smoking. I noticed that his cigar held a long, frail ash. It could not have been him I was chasing. He was sitting there quite calmly. A thick-necked, heavy fellow, easily out of breath. But he was breathing calmly now.

He sat up with amazement at my wild-eyed appearance, and the ash jarred from his cigar.

“Gregg! What in the devil—”

I tried to grin. “I’m on my way to bed—worked all night helping Snap with those damn Earth messages.”

I went past him, out the door into the main interior corridor. It was the only way the invisible prowler could have gone. But I was too late now—I could hear nothing. I dashed forward into the main lounge. It was empty, dim and silent, a silence broken presently by a faint click—a stateroom door hastily closing. I swung and found myself in a tiny transverse passage. The twin doors of A 22 and A 20 were before me.

The invisible eavesdropper had gone into one of these rooms! I listened at each of the panels, but there was only silence within.

The interior of the ship was suddenly singing with the steward’s siren—the call to awaken the passengers. It startled me. I moved swiftly away. But as the siren shut off, in the silence I heard a soft, musical voice:

“Wake up, Anita—I think that’s the breakfast call.”

And her answer: “All right, George. I hear it.”

CHAPTER IV
A Burn on a Martian Arm

I DID not appear at that morning meal. I was exhausted and drugged with lack of sleep. I had a moment with Snap, to tell him what had occurred. Then I sought out Carter. He had his little chart-room insulated. And we were cautious. I told him what Snap and I had learned: the Gamma rays from the moon, proving that Grantline had concentrated a considerable ore-body. I also told him the message from Grantline.

“We’ll stop on the way back, as he directs, Gregg.” He bent closer to me. “At Ferrok-Shahn I’m going to bring back a cordon of Interplanetary Police. The secret will be out, of course, when once we stop at the moon. We have no right, even now, to be flying this vessel as unguarded as it is.”

He was very solemn. And he was grim when I told him of the invisible eavesdropper.

“You think he overheard Grantline’s message?”

“I don’t know,” I said.

“Who was it? You seem to feel it was George Prince?”

“Yes.”

I was convinced that the prowler had gone into A 20. When I mentioned the purser, who seemed to have been watching me earlier in the night, and again was sitting in the smoking room when the eavesdropper fled past, Carter looked startled.

“Johnson is all right, Gregg.”

“Is he? Does he know anything about this Grantline affair?”

“No—no,” said the captain hastily. “You haven’t mentioned it, have you?”

“Of course I haven’t. I’ve been wondering why Johnson didn’t hear that eavesdropper. I could hear him when I was chasing him. But Johnson sat perfectly unmoved and let him go by. What was he sitting there for, anyway, at that hour of the morning?”

“You’re too suspicious, Gregg. Overwrought. But you’re right—we can’t be too careful. I’m going to have that Prince suite searched when I catch it unoccupied. Passengers don’t ordinarily travel with invisible cloaks. Go to bed, Gregg—you need a rest.”

I WENT to my cabin. It was located aft, on the stern deck-space, near the stern watch-tower. A small metal room, with a desk, a chair and bunk. I made sure no one was in it. I sealed the lattice grill and the door, set the alarm trigger against any opening of them, and went to bed.

The siren for the mid-day meal awakened me. I had slept heavily. I felt refreshed. And hungry.

I found the passengers already assembled at my table when I arrived in the dining salon. It was a low-vaulted metal room of blue and yellow tube-lights. At the sides its oval windows showed the deck, with its ports of the dome-side, through which a vista of the starry firmament was visible. We were well on our course to Mars. The moon had dwindled to a pin-point of light beside the crescent earth. And behind them our sun blazed, visually the largest orb in the heavens. It was some sixty-eight million miles from the earth to Mars, this voyage. A flight, under ordinary circumstances, of some ten days.

There were five tables in the dining salon, each with eight seats. Snap and I had one of the tables. We sat at the ends, with three passengers on each of the sides.

Snap was in his seat when I arrived. He eyed me down the length of the table.

“Good morning, Gregg. We missed you at breakfast. Not pressure-sick, I hope?”

There were three passengers already seated at our table—all men. Snap, in a gay mood, introduced me.

“This is our third officer, Gregg Haljan. Big, handsome fellow, isn’t he? And as pleasant as he is good-looking. Gregg, this is Sero Ob Hahn.”

I MET the keen, dark-eyed somber gaze of a Venus man of middle age. A small, slim, graceful man, with sleek black hair. His pointed face, accentuated by the pointed beard, was pallid. He wore a white and purple robe; upon his breast was a huge platinum ornament, a device like a star and cross entwined.

“I am happy to meet you, sir.” His voice was soft and sleek.

“Ob Hahn,” I repeated. “I should have heard of you, no doubt. But—”

A smile plucked at his thin, gray lips. “That is the error of mine, not yours. My mission is that all the universe shall hear of me.”

“He’s preaching the religion of the Venus Mystics,” Snap explained.

“And this enlightened gentleman,” said Ob Hahn ironically, “has just termed it fetishism. The ignorance—”

“Oh, I say!” protested the man at Ob Hahn’s side. “I mean, you seem to think I intended something opprobrious. As a matter of fact—”

“We’ve an argument, Gregg,” laughed Snap. “This is Sir Arthur Coniston, an English gentleman, lecturer and sky-trotter—that is, he will be a sky-trotter; he tells us he plans a number of voyages.”

The tall Englishman in his white linen suit bowed acknowledgment. “My compliments, Mr. Haljan. I hope you have no strong religious convictions, else we will make your table here very miserable!”

THE third passenger had evidently kept out of the argument. Snap introduced him as Rance Rankin. An American—a quiet, blond fellow of thirty-five or forty.

I ordered my breakfast and let the argument go on.

“Won’t make me miserable,” said Snap. “I love an argument. You said, Sir Arthur?...

“I mean to say, I think I said too much. Mr. Rankin, you are more diplomatic.”

Rankin laughed. “I am a magician,” he said to me. “A theatrical entertainer. I deal in tricks—how to fool an audience—” His keen, amused gaze was on Ob Hahn. “This gentleman from Venus and I have too much in common to argue.”

“A nasty one!” the Englishman exclaimed. “By Jove! Really, Mr. Rankin, you’re a bit too cruel!”

I could see we were doomed to have turbulent meals this voyage. I like to eat in quiet; arguing passengers always annoy me. There were still three seats vacant at our table; I wondered who would occupy them. I soon learned the answer—for one seat at least. Rankin said calmly:

“Where is the little Venus girl this meal?” His glance went to the empty seat at my right hand. “The Venza—wasn’t that her name? She and I are destined for the same theater in Ferrok-Shahn.”

So Venza was to sit beside me. It was good news. Ten days of a religious argument three times a day would be intolerable. But the cheerful Venza would help.

“She never eats the mid-day meal,” said Snap. “She’s on the deck, having orange juice. I guess it’s the old gag about diet, eh?”

MY attention wandered about the salon. Most of the seats were occupied. At the captain’s table I saw the objects of my search. George Prince and his sister sat one on each side of the captain. I saw George Prince in the life now as a man who looked hardly twenty-five. He was at this moment evidently in a gay mood. His clean-cut, handsome profile, with its poetic dark curls, was turned toward me. There seemed little of the villain about him.

And I saw Anita Prince now as a dark-haired, black eyed little beauty, in feature resembling her brother very strongly. She presently finished her meal. She rose, with him after her. She was dressed in Earth fashion—white blouse and dark jacket, wide, knee-length trousers of gray, with a red sash her only touch of color. She went past me, flashed me her smile and nod.

My heart was pounding. I answered her greeting, and met George Prince’s casual gaze. He, too, smiled, as though to signify that his sister had told him of the service I had done her. Or was his smile an ironical memory of how he had eluded me this morning when I chased him?

I gazed after his small, white-suited figure as he followed Anita from the salon. And thinking of her, I prayed that Carter and Halsey might be wrong. Whatever plotting against the Grantline Expedition might be going on, I hoped that George Prince was innocent of it. Yet I knew in my heart it was a futile hope. Prince had been that eavesdropper outside the helio-room. I could not really doubt it. But that his sister must be ignorant of what he was doing, I was sure.

MY attention was brought suddenly back to the reality of our table. I heard Ob Hahn’s silky voice:

“We passed quite close to the moon last night, Mr. Dean.”

“Yes,” said Snap. “We did, didn’t we? Always do—it’s a technical problem of the exigencies of interstellar navigation. Explain it to them, Gregg—you’re an expert.”

I waved it away with a laugh. There was a brief silence. I could not help noticing Sir Arthur Coniston’s queer look, and I think I have never seen so keen a glance as Rance Rankin shot at me. Were all these people aware of Grantline’s treasure on the moon? It suddenly seemed so. I wished fervently at that instant that the ten days of this voyage were over and we were safely at Ferrok-Shahn. Captain Carter was absolutely right. Coming back we would have a cordon of interplanetary police aboard.

Sir Arthur broke the awkward silence. “Magnificent sight, the moon, from so close a viewpoint—though I was too much afraid of pressure-sickness to be up to see it.”

I HAD nearly finished my hasty meal when another incident shocked me. The two other passengers at our table came in and took their seats. A Martian girl and man. The girl had the seat at my left, with the man beside her. All Martians are tall. This girl was about my own height—that is, six feet, two inches. The man was seven feet or more. Both wore the Martian outer robe. The girl flung hers back. Her limbs were encased in pseudo-mail. She looked, as all Martians like to look, a very warlike Amazon. But she was a pretty girl. She smiled at me with a keen-eyed, direct gaze.

“Mr. Dean said at breakfast that you were big and handsome. You are.”

They were brother and sister, these Martians. Snap introduced them as Set Miko and Setta Moa.⁵

5: “Set and Setta,” the Martian equivalent of Mr. and Miss.

This Miko was, from our Earth standards, a tremendous, brawny giant. Not spindly, like most Martians, this fellow, for all his seven feet of height, was almost heavy-set. He wore a plaited leather jerkin beneath his robe, and knee pants of leather out of which his lower legs showed as gray, hairy pillars of strength. He had come into the salon with a swagger, his sword-ornament clanking.

“A pleasant voyage so far,” he said to me as he started his meal. His voice had the heavy, throaty rasp characteristic of the Martian. He spoke perfect English—both Martians and Venus people are by heritage extraordinary linguists. Miko and his sister Moa had a touch of Martian accent, worn almost away by living for some years in Great-New York.

The shock to me came within a few minutes. Miko, absorbed in attacking his meal, inadvertently pushed back his robe to bare his forearm. An instant only, then it dropped again to his wrist. But in that instant I had seen, upon the gray flesh, a thin sear turned red. A very recent burn—as though a pencil-ray of heat had caught his arm.

My mind flung back. Only last night in the City Corridor, Snap and I had been followed by a Martian. I had shot at him with the heat-ray; I thought I had hit him on the arm. Was this the mysterious Martian who had followed us from Halsey’s office?

CHAPTER V
Venza the Venus Girl

It was shortly after that mid-day meal when I encountered Venza sitting on the starlit deck. I had been in the bow observatory; taken my routine castings of our position and worked them out. I was, I think, of the Planetara’s officers the most expert handler of the mathematical mechanical calculators. The locating of our position and charting the trajectory of our course was, under ordinary circumstances, about all I had to do. And it took only a few minutes each twelve hours.

I had a moment with Carter in the isolation of his chart-room.

“This voyage! Gregg, I’m getting like you—too fanciful. We’ve a normal group of passengers, apparently; but I don’t like the look of any of them. That Ob Hahn, at your table—”

“Snaky-looking fellow,” I commented. “He and the Englishman are great on arguments. Did you have Prince’s cabin searched?”

My breath hung on his answer.

“Yes. Nothing unusual among his things. We searched both his room and his sister’s.”

I did not follow that up. Instead I told him about the burn on Miko’s thick gray arm.

HE stared. “I wish to the Almighty we were at Ferrok-Shahn. Gregg, to-night when the passengers are asleep, come here to me. Snap will be here, and Dr. Frank. We can trust him.”

“He knows about—about the Grantline treasure?”

“Yes. And so do Balch and Blackstone.”

Balch and Blackstone were our first and second officers.

“We’ll all meet here, Gregg—say about the zero hour. We must take some precautions.”

He suddenly felt he should say no more now. He dismissed me.

I found Venza seated alone in a secluded corner of the starlit deck. A porthole, with the black heavens and the blazing stars, was before her. There was an empty seat nearby.

“Hola-lo,⁶ Gregg! Sit here with me. I have been wondering when you would come after me.”

6: A Venus form of jocular, intimate greeting.

I sat down beside her. “What are you doing—going to Mars, Venza? I’m glad to see you.”

“Many thanks. But I am glad to see you, Gregg. So handsome a man.... Do you know, from Venus to the earth and I have no doubt on all of Mars, no man will please me more.”

“Glib tongue,” I laughed. “Born to flatter the male—every girl of your world.” And I added seriously, “You don’t answer my question? What takes you to Mars?”

“Contract. By the stars, what else? Of course, a chance to make a voyage with you—”

“Don’t be silly, Venza.”

I ENJOYED her. I gazed at her small, slim figure gracefully reclining in the deck chair. Her long, gray robe parted—by design, I have no doubt—to display her shapely, satin-sheathed legs. Her black hair was coiled in a heavy knot at the back of her neck; her carmined lips were parted with a mocking, alluring smile. The exotic perfume of her enveloped me.

She glanced at me sidewise from beneath her sweeping black lashes.

“Be serious,” I added.

“I am serious. Sober. Intoxicated by you, but sober.”

I said, “What sort of a contract?”

“A theater in Ferrok-Shahn. Good money, Gregg. I’m to be there a year.” She sat up to face me. “There’s a fellow here on the Planetara, Rance Rankin, he calls himself. At our table—a big, good-looking blond American. He says he is a magician. Ever hear of him?”

“That’s what he told me. No, I never heard of him.”

“Nor did I. And I thought I had heard of everyone of any importance. He is listed for the same theater where I’m going. Nice sort of fellow.” She paused, and added suddenly, “If he’s a professional entertainer, I’m a motor-oiler.”

IT startled me. “Why do you say that?”

Instinctively my gaze swept the deck. An Earth woman and child and a small Venus man were in sight, but not within earshot.

“Why do you look so furtive?” she retorted. “Gregg, there’s something strange about this voyage. I’m no fool, nor you, and you know it as well as I do.”

“Rance Rankin—” I prompted.

She leaned closer toward me. “He could fool you. But not me—I’ve known too many real magicians.” She grinned. “I challenged him to trick me. You should have seen him trying to evade!”

“Do you know Ob Hahn?” I interrupted.

She shook her head. “Never heard of him. But he told me plenty at breakfast. By Satan, what a flow of words that devil-driver can muster! He and the Englishman don’t mesh very well, do they?”

She stared at me. I had not answered her grin; my mind was too busy with queer fancies. Halsey’s words: “Things are not always what they seem—” Were these passengers masqueraders? Put here by George Prince? And then I thought of Miko the Martian, and the burn upon his arm.

“Come back, Gregg! Don’t go wandering off like that!” She dropped her voice to a whisper. “I’ll be serious. I want to know what in the hell is going on aboard this ship. I’m a woman, and I’m curious. You tell me.”

“WHAT do you mean?” I parried.

“I mean a lot of things. What we’ve just been talking about. And what was the excitement you were in just before breakfast this morning?”

“Excitement?”

“Gregg, you may trust me.” For the first time she was wholly serious. Her gaze made sure no one was within hearing. She put her hand on my arm. I could barely hear her whisper: “I know they might have a ray upon us—I’ll be careful.”

“They?”

“Anyone. Something’s going on. You know it—you are in it. I saw you this morning, Gregg. Wild-eyed, chasing a phantom—”

“You?”

“And I heard the phantom! A man’s footsteps. A magnetic reflecting invisible cloak. You couldn’t fool an audience with that—it’s too commonplace. If Rance Rankin tried—”

I gripped her. “Don’t ramble, Venza! You saw me?”

“Yes. My stateroom door was open. I was sitting with a cigarillo. I saw the purser in the smoking room. He was visible from—”

“Wait! Venza, that prowler went through the smoking room!”

“I know he did. I could hear him.”

“Did the purser hear him?”

“Of course. The purser looked up, followed the sound with his gaze. I thought that was queer. He never made a move. And then you came along and he acted innocent. Why? What’s going on, that’s what I want to know!”

I HELD my breath. “Venza, where did the prowler run to? Can you—”

She whispered calmly, “Into A 20. I saw the door open and close—I even think I could see the blurred outline of him. Those magnetic cloaks!” She added, “Why should George Prince be sneaking around with you after him? And the purser acting innocent? And who is this George Prince, anyway?”

The huge Martian, Miko, with his sister Moa came strolling along the deck. They nodded as they passed us.

I whispered, “I can’t explain anything now. But you’re right, Venza: there is something going on. Listen! Whatever you learn—anything you encounter which looks unusual—will you tell me? I—well, I do trust you—really I do!—but the thing isn’t mine to tell.”

The somber pools of her eyes were shining. “You are very lovable, Gregg. I won’t question you.” She was trembling with excitement. “Whatever it is, I want to be in it. Here’s something I can tell you now. We’ve two high-class gold-leaf gamblers aboard. Did you know that?”

“No. Who are—”

“Shac and Dud Ardley. Let me state every detective in Great-New York knows them. They had a wonderful game with that Englishman, Sir Arthur Coniston, this morning. Stripped him of half a pound of eight-inch leaves—a neat little stack. A crooked game, of course. Those fellows are more nimble-fingered than Rance Rankin ever dared to be!”

I SAT staring at her. She was a mine of information, this girl.

“And Gregg, I tried my charms on Shac and Dud. Nice men, but dumb. Whatever’s going on, they’re not in it. They wanted to know what kind of a ship this was. Why? Because Shac has a cute little eavesdropping microphone of his own. He had it working in the night last night. He overheard George Prince and that big giant Miko arguing about the moon!”

I gasped. “Venza, softer!”

Against all propriety of this public deck she pretended to drape herself upon me. Her hair smothered my face as her lips almost touched my ear.

“Something about treasure on the moon—Shac couldn’t understand what. And they mentioned you. He didn’t hear what they said because the purser joined them.” Her whispered words tumbled over one another. “A hundred pounds of gold leaf—that’s the purser’s price. He’s with them, whatever it is. He promised to do something for them.”

She stopped. “Well?” I prompted.

“That’s all. Shac’s current was interrupted.”

“Tell him to try it again, Venza! I’ll talk with him. No! I’d better let him alone. Can you get him to keep his mouth shut?”

“I think he might do anything I told him. He’s a man.”

“Find out what you can.”

She sat away from me suddenly. “There’s Anita and George Prince.”

THEY came to the corner of the deck, but turned back. Venza caught my look. And understood it.

“So you love Anita Prince so much as that, Gregg?” Venza was smiling. “I wish you—I wish some man handsome as you would gaze after me like that.”

She turned solemn. “You may be interested to know that she loves you. I could see it. I knew it when I mentioned you to her this morning.”

“Me? Why, we’ve hardly spoken!”

“Is it necessary? I never heard that it was.”

I could not see Venza’s face; she stood up suddenly. And when I rose beside her, she whispered,

“We should not be seen talking so long. I’ll find out what I can.”

I stared after her slight robed figure as she turned into the lounge archway and vanished.

CHAPTER VI
A Traitor, and a Passing Asteroid

CAPTAIN CARTER was grim. “So they’ve bought him off, have they? Go bring him in here, Gregg. We’ll have it out with him now.”

Snap, Dr. Frank, Balch, our first officer, and I were in the captain’s chart-room. It was 4 P. M.—our Earth starting time. We were sixteen hours upon our voyage.

I found Johnson in his office in the lounge. “Captain wants to see you. Close up.”

He closed his window upon an American woman passenger who was demanding details of Martian currency, and followed me forward. “What is it, Gregg?”

“I don’t know.”

Captain Carter banged the slide upon us. The chart-room was insulated. The hum of the current was obvious. Johnson noticed it. He started at the hostile faces of the surgeon and Balch. And he tried to bluster.

“What is this? Something wrong?”

Carter wasted no words. “We have information, Johnson—there’s some under cover plot here aboard. I want to know what it is. Suppose you tell us frankly.”

THE purser looked blank. “What do you mean? We’ve gamblers aboard, if that’s—”

“To hell with that,” growled Balch. “You had a secret interview with that Martian, Set Miko, and with George Prince!”

Johnson scowled from under his heavy brows, and then raised them in surprise.

“Did I? You mean changing their money? I don’t like your tone, Balch. I’m not your under-officer!”

“But you’re under me,” roared the captain. “By God, I’m master here!”

“Well, I’m not disputing that,” said the purser mildly. “This fellow Balch—”

“We’re in no mood for argument,” Dr. Frank cut in. “Clouding the issue.”

“I won’t let it be clouded,” the captain exclaimed. I had never seen Carter so choleric. He was evidently under a tremendous strain. He added,

“Johnson, you’ve been acting suspiciously. I don’t give a damn whether I’ve proof of it or not—I say it. Did you, or did you not meet George Prince and that Martian last night?”

“No, I did not. And I don’t mind telling you, Captain Carter, that your tone also is offensive!”

“Is it?” Carter suddenly seized him. They were both big men. Johnson’s heavy face went purplish red.

“Take your hands!—” They were struggling. Carter’s hands were fumbling at the purser’s pockets. I leaped, flung an arm around Johnson’s neck, pinning him.

“Easy there! We’ve got you, Johnson!”

SNAP tried to help me. “Go on, bang him on the head, Gregg. Now’s your chance!”

We searched him. A heat-ray cylinder—that was legitimate. But we found a small battery and eavesdropping microphone similar to the one Venza had mentioned that Shac the gambler was carrying.

“What are you doing with that?” the captain demanded.

“None of your business! Is it criminal? Carter, I’ll have the Line officials dismiss you for this! Take your hands off me, all of you!”

“Look at this!” exclaimed Dr. Frank.

From Johnson’s breast pocket the surgeon drew a folded document. It was the scale drawing of the Planetara’s interior corridors, the lower control rooms and mechanisms. It was always kept in Johnson’s safe. And with it, another document: the ship’s clearance papers—the secret code pass-words for this voyage, to be used if we should be challenged by any interplanetary police ship.

Snap gasped. “My God, that was in my helio-room strong box! I’m the only one on this vessel except the captain who’s entitled to know those pass-words!”

Out of the silence, Balch demanded, “Well, what about it, Johnson?”

The purser was still defiant. “I won’t answer your questions, Balch. At the proper time, I’ll explain—Gregg Haljan, you’re choking me!”

I EASED up. But I shook him. “You’d better talk.”

He was exasperatingly silent.

“Enough!” exploded Carter. “He can explain when we get to port. Meanwhile I’ll put him where he’ll do no more damage. Gregg, lock him in the cage.”

We ignored his violent protestations. The cage—in the old days of sea-vessels on Earth, they called it the brig—was the ship’s jail. A steel-lined, windowless room located under the deck in the peak of the bow. I dragged the struggling Johnson there, with the amazed watcher looking down from the observatory window at our lunging, starlit forms.

“Shut up, Johnson! If you know what’s good for you—”

He was making a fearful commotion. Behind us, where the deck narrowed at the superstructure, half a dozen passengers were gazing in surprise.

“I’ll have you thrown out of the Service, Gregg Haljan!”

I shut him up finally. And flung him down the ladder into the cage and sealed the deck trap-door upon him. I was headed back for the chart-room when from the observatory came the lookout’s voice.

“An asteroid, Haljan! Officer Blackstone wants you.”

I hurried to the turret bridge. An asteroid was in sight. We had attained nearly our maximum speed now. An asteroid was approaching, so dangerously close that our trajectory would have to be altered. I heard Blackstone’s signals ringing in the control rooms; and met Carter as he ran to the bridge with me.

“That scoundrel! We’ll get more out of him, Gregg. By God, I’ll put the chemicals on him—torture him, illegal or not!”

WE had no time for further discussion. The asteroid was rapidly approaching. Already, under the glass, it was a magnificent sight. I had never seen this tiny world before—asteroids are not numerous between the Earth and Mars, or in toward Venus. I never expected to see this one again. How little of the future can we humans fathom, for all our science! If I could only have looked into the future, even for a few short hours! How different then would have been the outcome of this tragic voyage!

The asteroid came rushing at us. Its orbital velocity, I later computed, was some twenty-two miles a second. Our own, at the present maximum, was a fraction over seventy-seven. The asteroid had for some time been under observation by the lookout. He gave his warning only when it seemed that our trajectory should be altered to avoid a dangerously close passing.

At the combined speeds of nearly a hundred miles a second the asteroid swept into view. With the naked eye, at first it was a tiny speck of star-dust, unnoticed in the gem-strewn black velvet of Space. A speck. Then a gleaming dot, silver white, with the light of our Sun upon it.

Five minutes. The dot grew to a disc. Expanding. A full moon, silver-white. Brightest world in the firmament—the light from it bathed the Planetara, illumined the deck, painting everything with silver.

I stood with Carter and Blackstone on the turret bridge. It was obvious that unless we altered our course, the asteroid would pass too close for safety. Already we were feeling its attraction; from the control rooms came the report that our trajectory was disturbed by this new mass so near.

“Better make your calculations now, Gregg,” Blackstone suggested.

I CAST up the rough elements from the observational instruments in the turret. It took me some ten or fifteen minutes. When I had us upon our new course, with the attractive and repulsive plates in the Planetara’s hull set in their altered combinations, I went out to the bridge again.

The asteroid hung over our bow quarter. No more than twenty or thirty thousand miles away. A giant ball now, filling all that quadrant of the heavens. The configurations of its mountains—its land and water areas—were plainly visible. Its axial rotation was apparent.

“Perfectly habitable,” Blackstone said. “But I’ve searched all over this hemisphere with the glass. No sign of human life—certainly nothing civilized—nothing in the fashion of cities.”

A fair little world, by the look of it. A tiny globe: Blackstone had figured it at some eight hundred miles in diameter. There seemed a normal atmosphere. We could see areas where the surface was obscured by clouds. And oceans, and land masses. Polar icecaps. Lush vegetation at its equator.

Blackstone had roughly cast its orbital elements. A narrow ellipse. No wonder we had never encountered this fair little world before. It had come from the outer region beyond Neptune. At perihelion it would reach inside Mercury, round the Sun, and head outward again.

WE swept past the asteroid at a distance of some six thousand miles. Close enough, in very truth—a minute of flight at our combined speeds totaling a hundred miles a second. I had descended to the passenger deck, where I stood alone at a window, gazing.

The passengers were all gathered to view the passing little world. I saw, not far from me, Anita, standing with her brother; and the giant figure of Miko with them.

Half an hour since, first with the naked eye, this wandering little world had shown itself; it swam slowly past, began to dwindle behind us. A huge half moon. A thinner, smaller quadrant. A tiny crescent, like a silver bar-pin to adorn some lady’s breast. And then it was a dot, a point of light indistinguishable among the myriad others hovering in this great black void.

The incident of the passing of the asteroid was over. I turned from the deck window. My heart leaped. The moment for which all day I had been subconsciously longing was at hand. Anita was sitting in a deck chair, momentarily alone. Her gaze was on me as I looked her way, and she smiled an invitation for me to join her.

CHAPTER VII
Unspoken Love

Unspoken love! I think if I had yielded to the impulse of my heart, I would have poured out all those protestations of a lover’s ecstasy, incongruous here upon this starlit public deck, to a girl I hardly knew. I think, too, she might have received them with a tender acquiescence. The starlight was mirrored in her dark eyes. Misty eyes, with great reaches of unfathomable space in their depths. Yet I felt their tenderness.

Unfathomable strangeness of love! Who am I to write of it, with all the poets of all the ages striving to express the unexpressible? A bond, strangely fashioned by nature, between me and this little dark-haired Earth beauty. As though marked by the stars we were destined to be lovers....

Thus ran the romance of my unspoken thoughts. But I was sitting quietly in the deck chair, striving to regard her gentle beauty impersonally. And saying:

“But Miss Prince, why are you and your brother going to Ferrok-Shahn? His business—”

Even as I voiced it, I hated myself for such a question. So nimble is the human mind that mingled with my rhapsodies of love was my need for information of George Prince....

“Oh,” she said, “this is pleasure, not business, for George.” It seemed to me that a shadow crossed her expressive face. But it was gone in an instant, and she smiled. “We have always wanted to travel. We are alone in the world, you know—our parents died when we were children.”

I FILLED in her pause. “You will like Mars—so many interesting things to see.”

She nodded. “Yes, I understand so. Our Earth is so much the same all over, cast all in one mould.”

“But a hundred or two hundred years ago it was not, Miss Prince. I have read how the picturesque Orient, differing from—well, Great-New York, or London, for instance—”

“Transportation did that,” she interrupted eagerly. “Made everything the same—the people all look alike—dress alike.”

We discussed it. She had an alert, eager mind, childlike with its curiosity, yet strangely matured. And her manner was naïvely earnest. Yet this was no clinging vine, this little Anita Prince. There was a firmness, a hint of masculine strength in her chin, and in her manner.

“If I were a man, what wonders I could achieve in this marvelous age!” Her sense of humor made her laugh at herself. “Easy for a girl to say that,” she added.

“You have greater wonders to achieve, Miss Prince,” I said impulsively.

“Yes? What are they?” She had a very frank and level gaze, devoid of coquetry.

My heart was pounding. “The wonders of the next generation. A little son, cast in your own gentle image—”

What madness, this clumsy brash talk! I choked it off.

BUT she took no offense. The dark rose-petals of her cheeks were mantled deeper red, but she laughed.

“That is true.” She turned abruptly serious. “I should not laugh. The wonders of the next generation—conquering humans marching on....” Her voice trailed away. My hand went to her arm. Strange tingling something which poets call love! It burned and surged from my trembling fingers into the flesh of her forearm.

The starlight glowed in her eyes. She seemed to be gazing, not at the silver-lit deck, but away into distant reaches of the future. And she murmured:

“A little son, cast in my own gentle image. But with the strength of his father....”

Our moment. Just a breathless moment given us as we sat there with my hand burning her arm, as though we both might be seeing ourselves joined in a new individual—a little son, cast in his mother’s gentle image and with the strength of his father. Our moment, and then it was over. A step sounded. I sat back. The giant gray figure of Miko came past, his great cloak swaying, with his clanking sword-ornament beneath it. His bullet head, with its close-clipped hair, was hatless. He gazed at us, swaggered past, and turned the deck corner.

Our moment was gone. Anita said conventionally, “It has been pleasant to talk with you, Mr. Haljan.”

“But we’ll have many more,” I said. “Ten days—”

“You think we’ll reach Ferrok-Shahn on schedule?”

“Yes. I think so.... As I was saying, Miss Prince, you’ll enjoy Mars. A strange, aggressively forward-looking people.”

AN oppression seemed on her. She stirred in her chair.

“Yes, they are,” she said vaguely. “My brother and I know many Martians in Great-New York.” She checked herself abruptly. Was she sorry she had said that? It seemed so.

Miko was coming back. He stopped this time before us.

“Your brother would see you, Anita. He sent me to bring you to his room.”

The glance he shot me had a touch of insolence. I stood up, and he towered a head over me.

Anita said, “Oh yes. I’ll come.”

I bowed. “I will see you again, Miss Prince. I thank you for a pleasant half-hour.”

The Martian led her away. Her little figure was like a child with a giant. It seemed, as they passed the length of the deck with me staring after them, that he took her arm roughly. And that she shrank from him in fear.

And they did not go inside. As though to show me that he had merely taken her from me, he stopped at a distant deck window and stood talking to her. Once he picked her up as one would pick up a child to show it some distant object through the window.

“A little son with the strength of his father....” Her words echoed in my mind. Was Anita afraid of this Martian’s wooing? Yet held to him by some power he might have over her brother? The vagrant thought struck me.

Was it that?

CHAPTER VIII
A Scream in the Night

WE kept, on the Planetara, always the time and routine of our port of departure. The rest of that afternoon and evening were a blank of confusion to me. Anita’s words; the touch of my hand upon her arm; that vast realm of what might be for us, like a glimpse of a magic land of happiness which I had seen in her eyes, and perhaps she had seen in mine—all this surged within me.

I wandered about the vessel. I was not hungry. I did not go to the dining salon for dinner. I carried Johnson food and water to his cage; and sat, with my heat-cylinder upon him, listening to his threats of what would happen when he could complain to the Line’s higher officials.

But what was Johnson doing carrying a plan of the ship’s control rooms in his pockets? And worse: How had he dared open Snap’s box in the helio-room and abstract the code pass-words for this voyage? Without them we would be an outlawed vessel, subject to arrest if any patrol hailed us. Had Johnson been planning to sell those pass-words to Miko? I thought so. I tried to get the confession out of him, but could not.

I had a brief consultation with Captain Carter. He was genuinely apprehensive now. The Planetara carried no long-range guns, and very few side-arms. A half-dozen of the heat-ray hand projectors; a few old-fashioned weapons of explosion-rifles and automatic revolvers. And hand projectors with the new Benson curve-light. We had models of this for curved vision, so that one might see around a corner, so to speak. And with them, we could project the heat-ray in a curve as well.

THE weapons were all in Carter’s chart-room, save the few we officers always carried. Carter was apprehensive, but of what he could not say. He had not thought that our plan to stop at the Moon for treasure could affect this outward voyage. Any danger would be upon the way back, when the Planetara would be adequately guarded with long-range electronic guns, and manned with police-soldiers.

But now we were practically defenseless....

I had a moment with Venza, but she had nothing new to communicate to me.

And for half an hour I chatted with George Prince. He seemed a gay, pleasant young man. I could almost have fancied I liked him. Or was it because he was Anita’s brother? He told me how he looked forward to traveling with her on Mars. No, he had never been there before, he said.

He had a measure of Anita’s earnest naïve personality. Or was he a very clever scoundrel, with irony lurking in his soft voice, and a chuckle that he could so befool me?

“We’ll talk again, Haljan. You interest me—I’ve enjoyed it.”

He sauntered away from me, joining the saturnine Ob Hahn, with whom presently I heard him discussing religion.

The arrest of Johnson had caused considerable comment among the passengers. A few had seen me drag him forward to the cage. The incident had been the subject of passenger discussion all afternoon. Captain Carter had posted a notice to the effect that Johnson’s accounts had been found in serious error, and that Dr. Frank for this voyage would act in his stead.

IT was near midnight when Snap and I closed and sealed the helio-room and started for the chart-room, where we were to meet with Captain Carter and the other officers. The passengers had nearly all retired. A game was in progress in the smoking room, but the deck was almost deserted.

Snap and I were passing along one of the interior corridors. The stateroom doors, with the illumined names of the passengers, were all closed. The metal grid of the floor echoed our footsteps. Snap was in advance of me. His body suddenly rose in the air. He went like a balloon to the ceiling, struck it gently, and all in a heap came floating down and landed on the floor!

“What in the infernal!—”

He was laughing as he picked himself up. But it was a brief laugh. We knew what had happened: the artificial gravity-controls in the base of the ship, which by magnetic force gave us normality aboard, were being tampered with! For just this instant, this particular small section of this corridor had been cut off. The slight bulk of the Planetara, floating in space, had no appreciable gravity pull on Snap’s body, and the impulse of his step as he came to the unmagnetized area of the corridor had thrown him to the ceiling. The area was normal now. Snap and I tested it gingerly.

He gripped me. “That never went wrong by accident, Gregg! Someone down there—”

WE rushed to the nearest descending ladder. In the deserted lower room the bank of dials stood neglected. A score of dials and switches were here, governing the magnetism of different areas of the ship. There should have been a night operator, but he was gone.

Then we saw him lying nearby, sprawled face down on the floor! In the silence and dim lurid glow of the fluorescent tubes, we stood holding our breaths, peering and listening. No one here.

The guard was not dead. He lay unconscious from a blow on the head. A brawny fellow. We had him revived in a few moments. A broadcast flash of the call-buzz brought Dr. Frank in haste from the chart-room.

“What’s the matter?”

We pointed at the unconscious man. “Someone was here,” I said hastily. “Experimenting with the magnetic switches. Evidently unfamiliar with them—pulling one or another to test their workings and so see the reactions on the dials.”

We told him what had happened to Snap in the upper corridor.

Dr. Frank revived the guard in a moment. He was no worse off for the episode, save a lump on his head, and a nasty headache.

But he had little to tell us. He had heard a step. Saw nothing—and then had been struck on the head, by some invisible assailant.

WE left him nursing his head, sitting belligerent at his post. Armed now with my heat-ray cylinder which I loaned him.

“Strange doings this voyage,” he told us. “All the crew knows it—all been talkin’ about it. I stick it out now, but when we get back home I’m done with this star travelin’. I belong on the sea anyway. A good old freighter is all right for me.”

We hurried back to the upper level. We would indeed have to plan something at this chart-room conference. This was the first tangible attack our adversaries had made.

We were on the passenger deck headed for the chart-room when all three of us stopped short, frozen with horror. Through the silent passenger quarters a scream rang out! A girl’s shuddering, gasping scream. Terror in it. Horror. Or a scream of agony. In the silence of the dully vibrating ship it was utterly horrible. It lasted an instant—a single long scream; then was abruptly stilled.

And with blood pounding my temples and rushing like ice through my veins, I recognized it.

Anita!

CHAPTER IX
The Murder in A 22

“GOOD GOD, what was that?” Dr. Frank’s face had gone white in the starlight. Snap stood like a statue of horror.

The deck here was patched as always, silver radiance from the deck ports. The empty deck chairs stood about. The scream was stilled, but now we heard a commotion inside—the rasp of opening cabin doors; questions from frightened passengers; the scurry of feet.

I found my voice. “Anita! Anita Prince!”

“Come on!” shouted Snap. “Was it the Prince girl? I thought so too! In her stateroom, A 22!” He was dashing for the lounge archway.

Dr. Frank and I followed. I realized that we passed the deck door and window of A 22. But they were dark, and evidently sealed on the inside. The dim lounge was in a turmoil; passengers standing at their cabin doors. I heard Sir Arthur Coniston:

“I say, what was that?”

“Over there,” said another man. “Come back inside, Martha.” He shoved his wife back. “Mr. Haljan!” He plucked at me as I went past.

I shouted, “Go back to your rooms! We want order here—keep back!”

We came to the twin doors of A 22 and A 20. Both were closed. Dr. Frank was in advance of Snap and me. He paused at the sound of Captain Carter’s voice behind us.

“Was it from in there? Wait a moment!”

Carter dashed up; he had a large heat-ray projector in his hand. He shoved us aside. “Let me in first. Is the door sealed? Gregg, keep those passengers back!”

THE door was not sealed. Carter burst into the room. I heard him gasp, “Good God!”

Snap and I shoved back three or four crowding passengers, and in that instant Dr. Frank had been in the room and out again.

“There’s been an accident! Get back, Gregg! Snap, help him keep the crowd away.” He shoved me forcibly.

From within, Carter was shouting, “Keep them out! Where are you, Frank? Come back here! Send a flash for Balch—I want Balch!”

Dr. Frank went back into the room and banged the cabin door upon Snap and me. I was unarmed—I had loaned my cylinder to the guard in the lower corridor. Weapon in hand, Snap forced the panic-stricken passengers back to their rooms.

“It’s all right! An accident! Miss Prince is hurt.”

Snap reassured them glibly; but he knew no more about it than I. Moa, with a night-robe drawn tight around her thin, tall figure, edged up to me.

“What has happened, Set Haljan?”

I gazed around for her brother Miko, but did not see him.

“An accident,” I said shortly. “Go back to your room. Captain’s orders.”

She eyed me and then retreated. Snap was threatening everybody with his cylinder. Balch dashed up. “What in the hell? Where’s Carter?”

“In there.” I pounded on A 22. It opened cautiously. I could see only Carter, but I heard the murmuring voice of Dr. Frank through the interior connecting door to A 20.

THE captain rasped, “Get out, Haljan! Oh, is that you, Balch? Come in.” He admitted the older officer and slammed the door again upon me. And immediately reopened it.

“Gregg, keep the passengers quiet. Tell them everything’s all right. Miss Prince got frightened, that’s all. Then go up to the turret. Tell Blackstone what’s happened.”

“But I don’t know what’s happened,” I protested miserably.

Carter was grim and white. He whispered, “I think it may turn out to be murder, Gregg! No, not dead yet—Dr. Frank is trying—Don’t stand there like an ass, man! Get to the turret! Verify our trajectory—no—wait—”

The captain was almost incoherent. “Wait a minute, I don’t mean that! Tell Snap to watch his helio-room. Gregg, you and Blackstone stay in the chart-room. Arm yourselves and guard our weapons. By God, this murderer, whoever he is—”

I stammered, “If—if she dies—will you flash us word?”

He stared at me strangely. “I’ll be there presently, Gregg.”

He slammed the door upon me.

I followed his orders, but it was like a dream of horror. The turmoil of the ship gradually quieted. Snap went to the helio-room; Blackstone and I sat in the tiny steel chart-room. How much time passed, I do not know. I was confused. Anita hurt! She might die.... Murdered.... But why? By whom? Had George Prince been in his own room when the attack came? I thought now I recalled hearing the low murmur of his voice in there with Dr. Frank and Carter.

Where was Miko? It stabbed at me. I had not seen him among the passengers in the lounge.

CARTER came into the chart-room. “Gregg, you get to bed—you look like a ghost!”

“But—”

“She’s not dead—she may live. Dr. Frank and her brother are with her. They’re doing all they can.” He told us what had happened. Anita and George Prince had both been asleep, each in their respective rooms. Someone unknown had opened Anita’s corridor door.

“Wasn’t it sealed?” I demanded.

“Yes. But the intruder opened it.”

“Burst it? I didn’t think it was broken.”

“It wasn’t broken. The assailant opened it somehow, and assaulted Miss Prince—shot her in the chest with a heat-ray. Her left lung.”

“She is conscious?” Balch demanded.

“Yes. But she did not see who did it. Nor did Prince. Her scream awakened him, but the intruder evidently fled out the corridor door of A 22, the way he entered.”

I stood weak and shaken at the chart-room entrance. “A little son, cast in the gentle image of his mother. But with the strength of his father....” But Anita—dying, perhaps; and all my dreams were fading into a memory of what might have been.

“You go to bed, Gregg—we don’t need you.”

I was glad enough to get away. I would lie down for an hour, and then go to Anita’s stateroom. I’d demand that Dr. Frank let me see her, if only for a moment.

I WENT to the stern deck-space where my cubby was located. My mind was confused, but some instinct within me made me verify the seals of my door and window. They were intact. I entered cautiously, switched on the dimmer of the tube-lights, and searched the room. It had only a bunk, my tiny desk, a chair and clothes robe.

There was no evidence of any intruder here. I set my door and window alarm. Then I audiphoned to the helio-room.

“Snap?”

“Yes.”

I told him about Anita. Carter cut in on us from the chart-room. “Stop that, you fools!”

We cut off. Fully dressed, I flung myself on my bed. Anita might die....

I must have fallen into a tortured sleep. I was awakened by the sound of my alarm buzzer. Someone was tampering with my door! Then the buzzer ceased; the marauder outside must have found a way of silencing it. But it had done its work—awakened me.

I had switched off the light; my cubby was Stygian dark. A heat-cylinder was in the bunk-bracket over my head; I searched for it, pried it loose softly.

I was fully awake. Alert. I could hear a faint sizzling—someone outside trying to unseal the door. In the darkness, cylinder in hand, I crept from the bunk. Crouched at the door. This time I would capture or kill this night prowler.

THE sizzling was faintly audible. My door-seal was breaking. Upon impulse I reached for the door, jerked it open.

No one there! The starlit segment of deck was empty. But I had leaped, and I struck a solid body, crouching in the doorway. A giant man. Miko!

His electronized metallic robe burned my hands. I lunged against him—I was almost as surprised as he. I shot, but the stab of heat evidently missed him.

The shock of my encounter close-circuited his robe; he materialized in the starlight. A brief, savage encounter. He struck the weapon from my hand. He had dropped his hydrogen torch, and tried to grip me. But I twisted away from his hold.

“So it’s you!”

“Be quiet, Gregg Haljan! I only want to talk.”

Without warning, a stab of radiance shot from a weapon in his hand. It caught me. Ran like ice through my veins. Seized and numbed my limbs.

I fell helpless to the deck. Nerves and muscles paralyzed. My tongue was thick and inert. I could not speak, nor move. But I could see Miko bending over me. And hear him:

“I don’t want to kill you, Haljan. We need you.”

He gathered me up like a bundle in his huge arms; carried me swiftly across the deserted deck.

Snap’s helio-room in the network under the dome was diagonally overhead. A white actinic light shot from it—caught us, bathed us. Snap had been awake; had heard the slight commotion of our encounter.

His voice rang shrilly: “Stop! I’ll shoot!” His warning siren rang out to arouse the ship. His spotlight clung to us.

Miko ran with me a few steps. Then he cursed and dropped me, fled away. I fell like a sack of carbide to the deck. My senses faded into blackness....

“HE'S all right now.”

I was in the chart-room, with Captain Carter, Snap and Dr. Frank bending over me. The surgeon said,

“Can you speak now, Gregg?”

I tried it. My tongue was thick, but it would move. “Yes.”

I was soon revived. I sat up, with Dr. Frank vigorously rubbing me.

“I’m all right.” I told them what had happened.

Captain Carter said abruptly, “Yes, we know that. And it was Miko also who killed Anita Prince. She told us before she died.”

“Died!...” I leaped to my feet. “She ... died....”

“Yes, Gregg. An hour ago, Miko got into her stateroom and tried to force his love on her. She repulsed him—he killed her.”

It struck me blank. And then with a rush came the thought, “He says Miko killed her....”

I heard myself stammering, “Why—why we must get him!” I gathered my wits; a surge of hate swept me; a wild desire for vengeance.

“Why, by God, where is he? Why don’t you go get him? I’ll get him—I’ll kill him, I tell you!”

“Easy, Gregg!” Dr. Frank gripped me.

The captain said gently, “We know how you feel, Gregg. She told us before she died.”

“I’ll bring him in here to you! But I’ll kill him, I tell you!”

“No you won’t, lad. You’re hysterical now. We don’t want him killed, not attacked even. Not yet. We’ll explain later.”

They sat me down, calming me.

Anita dead. The door of the shining garden was closed. A brief glimpse, given to me and to her of what might have been. And now she was dead....

CHAPTER X
A Speck of Human Earth-dust, Falling Free....

I HAD not been able at first to understand why Captain Carter wanted Miko left at liberty. Within me there was that cry of vengeance, as though to strike Miko down would somehow lessen my own grief at Anita’s loss. Whatever Carter’s purpose, Snap had not known it. But Balch and Dr. Frank were in the captain’s confidence—all three of them working on some plan of action. Snap and I argued it, and thought we could fathom it; and in spite of my desire to kill Miko, the thing looked reasonable.

It was obvious that at least two of our passengers were plotting with Miko and George Prince; trying during this voyage to learn what they could about Grantline’s activities on the Moon; scheming doubtless to seize the treasure when the Planetara stopped at the Moon on the return voyage. I thought I could name those masquerading passengers. Ob Hahn, supposedly a Venus Mystic. And Rance Rankin, who called himself an American magician. Those two, Snap and I agreed, seemed most suspicious. And there was the purser.

With my hysteria still on me, I sat for a time on the deck outside the chart-room with Snap. Then Carter summoned us back, and we sat listening while he, Balch and Dr. Frank went on with their conference. Listening to them I could not but agree that our best plan was to secure evidence which would incriminate all who were concerned in the plot. Miko, we were convinced, had been the Martian who followed Snap and me from Halsey’s office in Great-New York. George Prince had doubtless been the invisible eavesdropper outside the helio-room. He knew, and had told the others, that Grantline had found radium-ore on the Moon—that the Planetara would stop there on the way home.

BUT we could not incarcerate George Prince for being an eavesdropper. Nor had we the faintest tangible evidence against Ob Hahn or Rance Rankin. And even the purser would probably be released by the Interplanetary Court of Ferrok-Shahn when it heard our evidence.

There was only Miko. We could arrest him for the murder of Anita. But the others would be put on their guard. It was Carter’s idea to let Miko remain at liberty for a time and see if we could not identify and incriminate his fellows. The murder of Anita obviously had nothing to do with any plot against the Grantline Moon treasure.

“Why,” exclaimed Balch, “there might be—probably are—huge Martian interests concerned in this thing. These men here aboard are only emissaries, making this voyage to learn what they can. When they get to Ferrok-Shahn they’ll make their report, and then we’ll have a real danger on our hands. Why, an outlaw ship could be launched from Ferrok-Shahn that would beat us back to the Moon—and Grantline is entirely without warning of any danger!”

It seemed obvious. Unscrupulous, moneyed criminals in Ferrok-Shahn would be dangerous indeed, once these details of Grantline were given them. And so now it was decided that in the remaining nine days of our outward voyage, we would attempt to secure enough evidence to arrest all these plotters.

“I’ll have them all in the cage when we land,” Carter declared grimly. “They’ll make no report to their principals. The thing will end, be stamped out!”

Ah, the futile plans of men!

YET we thought it practical. We were all doubly armed now. Explosive bullet-projectors and the heat-ray cylinders. And we had several eavesdropping microphones which we planned to use whenever occasion offered.

It was now, Earth Eastern Time, A. M. Twenty-eight hours only of this eventful voyage were passed. The Planetara was some six million miles from the Earth; it blazed behind us, a tremendous giant.

The body of Anita was being made ready for burial. George Prince was still in his stateroom. Glutz, effeminate little hairdresser, who waxed rich acting as beauty doctor for the women passengers, and who in his youth had been an undertaker, had gone with Dr. Frank to prepare the body.

Gruesome details. I tried not to think of them. I sat, numbed, in the chart-room.

An astronomical burial—there was little precedent for it. I dragged myself to the stern deck-space where, at five A. M., the ceremony took place. Most of the passengers were asleep, unaware of all this—which was why Carter hastened it.

We were a solemn little group, gathered there in the checkered starlight with the great vault of the heavens around us. A dismantled electronic projector—necessary when a long-range gun was mounted—had been rigged up in one of the deck ports.

They brought out the body. I stood apart, gazing reluctantly at the small bundle, wrapped like a mummy in a dark metallic screen-cloth. A patch of black silk rested over her face.

FOUR cabin stewards carried her. And beside her walked George Prince. A long black robe covered him, but his head was bare. And suddenly he reminded me of the ancient play-character of Hamlet. His black, wavy hair; his finely chiseled, pallid face, set now in a stern, patrician cast. And staring, I realized that however much of a villain this man not yet thirty might be, at this instant, walking beside the body of his dead sister, he was stricken with grief. He loved that sister with whom he had lived since childhood; and to see him now, with his set white face, no one could doubt it.

The little procession stopped in a patch of starlight by the port. They rested the body on a bank of chairs. The black-robed Chaplain, roused from his bed and still trembling from excitement of this sudden, inexplicable death on board, said a brief, solemn little prayer. An appeal: That the Almighty Ruler of all these blazing worlds might guard the soul of this gentle girl whose mortal remains were now to be returned to Him.

Ah, if ever God seemed hovering close, it was now at this instant, on this starlit deck floating in the black void of space.

Then Carter for just a moment removed the black shroud from her face. I saw her brother gaze silently; saw him stoop and implant a kiss—and turn away. I did not want to look, but I found myself moving slowly forward.

SHE lay, so beautiful. Her face, white and calm and peaceful in death. My sight blurred. Words seemed to echo: “A little son, cast in the gentle image of his mother....”

“Easy, Gregg!” Snap was whispering to me. He had his arm around me. “Come on away!”

They tied the shroud over her face. I did not see them as they put her body in the tube, sent it through the exhaust-chamber, and dropped it.

But a moment later I saw it—a small black oblong bundle—hovering beside us. It was perhaps a hundred feet away, circling us. Held by the Planetara’s bulk, it had momentarily become our satellite. It swung around us like a moon. Gruesome satellite, by nature’s laws forever to follow us.

Then from another tube at the bow, Blackstone operated a small Zed-co-ray projector. Its dull light caught the floating bundle, neutralizing its metallic wrappings.

It swung off at a tangent. Speeding. Falling free in the dome of the heavens. A rotating black oblong. But in a moment distance dwindled it to a speck. A dull silver dot with the sunlight on it. A speck of human Earth-dust, falling free....

It vanished. Anita—gone. In my heart was an echo of the prayer that the Almighty might watch over her and guard her always....

CHAPTER XI
The Electrical Eavesdropper

I TURNED from the deck. Miko was near me! So he had dared to show himself here among us! But I realized that he could not be aware we knew he was the murderer. George Prince had been asleep, had not seen Miko with Anita. Miko, with impulsive rage, had shot the girl and escaped. No doubt now he was cursing himself for having done it. And he could very well assume that Anita had died without regaining consciousness to tell who had killed her.

He gazed at me now, here on the deck. I thought for an instant he was coming over to talk to me. Though he probably considered he was not suspected of the murder of Anita, he realized, of course, that his attack on me was known; he must have wondered what action Captain Carter would take.

But he did not approach me; he moved away, and went inside. Moa had been near him; and as though by pre-arrangement with him she now accosted me.

“I want to speak to you, Set Haljan.”

“Go ahead.”

I felt an instinctive aversion for this Martian girl. Yet she was not unattractive. Over six feet tall, straight and slim. Sleek blond hair. Rather a handsome face. Not gray, like the burly Miko, but pink and white. Stern-lipped, yet feminine, too. She was smiling gravely now. Her blue eyes regarded me keenly. She said gently:

“A sad occurrence, Gregg Haljan. And mysterious. I would not question you—”

“Is that all you have to say?” I demanded, when she paused.

“No. You are a handsome man, Gregg—attractive to women—to any Martian woman.”

SHE said it impulsively. Admiration for me was on her face, in her eyes—a man cannot miss it.

“Thank you.”

“I mean, I would be your friend. My brother Miko is so sorry about what happened between you and him this morning. He only wanted to talk to you, and he came to your cubby door—”

“With a torch to break its seal,” I interjected.

She waved that away. “He was afraid you would not admit him. He told you he would not hurt you.”

“And so he struck me with one of your cursed Martian paralyzing rays!”

“He is sorry....”

She seemed gauging me, trying, no doubt, to find out what reprisal would be taken against her brother. I felt sure that Moa was as active as a man in any plan that was under way to capture the Grantline treasure. Miko, with his ungovernable temper, was doing things that put their plans in jeopardy.

I demanded abruptly, “What did your brother want to talk to me about?”

“Me,” she said surprisingly. “I sent him. A Martian girl goes after what she wants. Did you know that?”

She swung on her heel and left me. I puzzled over it. Was that why Miko had struck me down, and was carrying me off? Was my accursed masculine beauty so attractive to this Martian girl? I did not think so. I could not believe that all these incidents were so unrelated to what I knew was the main undercurrent. They wanted me, had tried to capture me. For something else than because Moa liked my looks....

DR. FRANK found me mooning alone.

“Go to bed, Gregg! You look awful.”

“I don’t want to go to bed.”

“Where’s Snap?”

“I don’t know. He was here a while ago.” I had not seen him since the burial of Anita.

“The captain wants him.” The surgeon left me.

Within an hour the morning siren would arouse the passengers. I was seated in a secluded corner of the deck, when George Prince came along. He went past me, a slight, somber, dark-robed figure. He had on high, thick boots. A hood was over his head, but as he saw me he pushed it back and dropped down beside me.

But for a moment he did not speak. His face showed pallid in the pallid star-gleams.

“She said you loved her.” His soft voice was throaty with emotion.

“Yes.” I said it almost against my will. There seemed a bond springing between this bereaved brother and me. He added, so softly I could barely hear him, “That makes you, I think, almost my friend. And you thought you were my enemy.”

I held my answer. An incautious tongue running under emotion is a dangerous thing. And I was sure of nothing.

HE went on, “Almost my friend. Because—we both loved her, and she loved us both.” He was hardly more than whispering. “And there is aboard—one whom we both hate.”

“Miko!” It burst from me.

“Yes. But do not say it.”

Another silence fell between us. He brushed back the black curls from his forehead. And his dark eyes searched mine.

“Have you an eavesdropping microphone, Haljan?”

I hesitated. “Yes.”

“I was thinking....” He leaned closer toward me. “If, in half an hour, you could use it upon Miko’s cabin—I would rather tell you than the captain or anyone else. The cabin will be insulated, but I shall find a way of cutting off that insulation so that you may hear.”

So George Prince had turned with us! The shock of his sister’s death—himself allied to her murderer!—had been too much for him. He was with us!

Yet his help must be given secretly. Miko would kill him in an instant if it became known.

He had been watchful of the deck. He stood up now.

“I think that is all.”

As he turned away, I murmured, “But I do thank you....”

THE name Set Miko glowed upon the small metal door. It was in a transverse corridor similar to A 22. The corridor was forward of the lounge: it opened off the small circular library.

The library was unoccupied and unlighted, dim with only the reflected lights from the nearby passages. I crouched behind a cylinder-case. The door of Miko’s room was in sight, being some thirty feet away from me.

I waited perhaps five minutes. No one entered. Then I realized that doubtless the conspirators were already there. I set my tiny eavesdropper on the library floor beside me; connected its little battery; focused its projector. Was Miko’s room insulated? I could not tell. There was a small ventilating grid above the door. Across its opening, if the room were insulated, a blue sheen of radiance would be showing. And there would be a faint hum. But from this distance I could not see or hear such details, and I was afraid to approach closer. Once in the transverse corridor, I would have no place to hide, no way of escape; if anyone approached Miko’s door, I would be discovered.

I threw the current into my little apparatus. I prayed, if it met interference, that the slight sound would pass unnoticed. George Prince had said he would make opportunity to disconnect the room’s insulation. He had evidently done so. I picked up the interior sounds at once; my headphone vibrated with them. And with trembling fingers on the little dial between my knees as I crouched in the darkness behind the cylinder-case, I synchronized.

“Johnson is a fool.” It was Miko’s voice. “We must have the pass-words.”

“He got them from the helio-room.” A man’s voice; I puzzled over it at first, then recognized it. Rance Rankin.

MIKO said, “He is a fool. Walking around this ship as though with letters blazoned on his forehead—‘Watch me—I need watching—’ Hah! No wonder they apprehended him!”

Was George Prince in there? Rankin’s voice said: “He would have turned the papers over to us. I would not blame him too much. What harm—”

“Oh, I’ll release him,” Miko declared. “What harm? That braying ass did us plenty of harm. He has lost the pass-words. Better he had left them in the helio-room.”

Moa was in the room. Her voice said: “We’ve got to have them. The Planetara, upon such an important voyage as this, may be watched. How do we know—”

“It is, no doubt,” Rankin said quietly. “We ought to have the pass-words. When we are in control of this ship....”

It sent a shiver through me. Were they planning to try and seize the Planetara? Now? It seemed so.

“Johnson undoubtedly memorized them,” Moa was saying. “When we get him out—”

“Hahn is to do that, at the signal.” Miko added, “George could do it better, perhaps.”

And then I heard George Prince for the first time. He murmured, “I will try.”

“No need,” said Miko. “I praise where praise is deserved. And I have little praise for you now, George!”

I could not see what happened. A look, perhaps, which Prince could not avoid giving this man he had come to hate. Miko doubtless saw it, and the Martian’s hot anger leaped.

Rankin said hurriedly, “Stop that!”

And Moa: “Let him alone! Sit down, you fool!”

I COULD hear the sound of a scuffle. A blow—a cry, half suppressed, from George Prince.

Then Miko: “I will not hurt him. Craven coward! Look at him! Hating me—frightened!”

I could fancy George Prince sitting there with murder in his heart, and Miko taunting him:

“Hates me now, because I shot his sister!”

Moa: “Hush!”

“I will not! Why should I not say it? I will tell you something else, George Prince. It was not Anita I shot at, but you! I meant nothing for her, but love. If you had not interfered—”

This was different from what we had figured. George Prince had come in from his own room, had tried to rescue his sister, and in the scuffle, Anita had taken the shot intended for George.

“I did not even know I had hit her,” Miko was saying. “Not until I heard she was dead.” He added sardonically, “I hoped it was you I had hit, George. And I will tell you this: You hate me no more than I hate you. If it were not for your knowledge of radium ores—”

“Is this to be a personal wrangle?” Rankin interrupted. “I thought we were here to plan—”

“It is planned,” Miko said shortly. “I give orders, I do not plan. I am waiting now for the moment—”

HE checked himself. Moa said, “Does Rankin understand that no harm is to come to Gregg Haljan?”

“Yes,” said Rankin. “And Dean. We need them, of course. But you cannot make Dean send messages if he refuses, nor make Haljan navigate.”

“I know enough to check on them,” Miko said grimly. “They will not fool me. And they will obey me, have no fear. A little touch of sulphuric—” His laugh was gruesome. “It makes the most stubborn very willing.”

“I wish,” said Moa, “we had Haljan safely hidden. If he is hurt—killed—”

So that was why Miko had tried to capture me? To keep me safe so that I might navigate the ship.

It occurred to me that I should get Carter at once. A plot to seize the Planetara? But when?

I froze with startled horror.

The diaphragms at my ears rang with Miko’s words: “I have set the time for now! In two minutes—”

It seemed to startle both Rankin and George Prince almost as much as I. Both exclaimed:

“No!”

“No? Why not? Everyone is at his post!”

Prince repeated: “No!”

And Rankin: “But can we trust them? The stewards—the crew?”

“Eight of them are our own men! You didn’t know that, Rankin? They’ve been aboard the Planetara for several voyages. Oh, this is no quickly-planned affair, even though we let you in on it so recently. You and Johnson. By God!”

I CROUCHED tense. There was a commotion in the stateroom. Miko had discovered that his insulation was cut off! He had evidently leaped to his feet; I heard a chair overturn. And the Martian’s roar: “It’s off! Did you do that, Prince? By God, if I thought—”

My apparatus went suddenly dead as Miko flung on his insulation. I lost my wits in the confusion; I should have instantly taken off my vibrations. There was interference; it showed in the dark space of the ventilator grid over Miko’s doorway; a snapping in the air there, a swirl of sparks.

I heard with my unaided ears Miko’s roar over his insulation: “By God, they’re listening!”

The scream of a hand-siren sounded from his stateroom. It rang over the ship. His signal! I heard it answered from some distant point. And then a shot; a commotion in the lower corridors....

The attack upon the Planetara had started!

I was on my feet. The shouts of startled passengers sounded, a turmoil beginning everywhere.

I stood momentarily transfixed. The door of Miko’s stateroom burst open. He stood there, with Moa, Rankin and George Prince crowding behind him.

He saw me. “You, Gregg Haljan!”

He came leaping at me.

CHAPTER XII
The Weightless Combat

I WAS taken wholly by surprise. There was an instant when I stood numbed, fumbling for a weapon at my belt, undecided whether to run or stand my ground. Miko was no more than twenty feet from me. He checked his forward rush. The light from an overhead tube was on him; I saw in his hand the cylinder projector of his paralyzing ray.

I plucked my heat-cylinder from my belt, and fired without taking aim. My tiny heat-beam flashed. I must have grazed Miko’s hand. His roar of anger and pain rang out over the turmoil. He dropped his weapon; then stooped to pick it up. But Moa forestalled him. She leaped and seized it.

“Careful! Fool—you promised not to hurt him!”

A confusion of swift action. Rankin had turned and darted away. I saw George Prince stumbling half in front of the struggling Miko and Moa. And I heard footsteps beside me; a hand gripped me, jerked at me.

Over the turmoil Prince’s voice sounded: “Gregg—Haljan!”

I recall I had the impression that Prince was frightened; he had half fallen in front of Miko. And there was Miko’s voice:

“Let go of me!”

And Moa: “Come!”

It was Balch gripping me. “Gregg! This way—run! Get out of here! He’ll kill you with that ray—”

Miko’s ray flashed, but George Prince had knocked at his arm. I did not dare fire again. Prince was in the way. Balch, who was unarmed, shoved me violently back.

“Gregg—the chart-room!”

I TURNED and ran, with Balch after me. Prince had fallen, or been felled by Miko. A flash followed me. Miko’s weapon, but again it missed. He did not pursue me; he ran the other way, through the port-side door of the library.

Balch and I found ourselves in the lounge. Shouting, frightened passengers were everywhere. The place was in wild confusion, the whole ship ringing now with shouts.

“To the chart-room, Gregg!”

I called to the passengers: “Get back to your rooms!”

I followed Balch. We ran through the archway to the deck. In the starlight I saw figures scurrying aft, but none were near us. The deck forward was dim with heavy shadows. The oval window and door of the chart-room were blue-yellow from the tube-lights inside. No one seemed on the deck there; and then, as we approached, I saw, further forward in the bow, the trap-door to the cage standing open. Johnson had been released.

From one of the chart-room windows a heat-ray sizzled. It barely missed us. Balch shouted, “Carter—don’t!”

The captain called, “Oh—you, Balch—and Haljan—”

He came out on the deck as we rushed up. His left arm was dangling limp.

“God—this—” He got no further. From the turret overhead a tiny search-beam came down and disclosed us. Blackstone was supposed to be on duty up there, with a course-master at the controls. But, glancing up, I saw, illumined by the turret lights, the figures of Ob Hahn in his purple-white robe, and Johnson the purser. And on the turret balcony, two fallen men—Blackstone and the course-master.

JOHNSON was training the spotlight on us. And Hahn fired a Martian ray. It struck Balch beside me. He dropped.

Carter was shouting, “Inside! Gregg, get inside!”

I stopped to raise up Balch. Another beam came down. A heat-ray this time. It caught the fallen Balch full in the chest, piercing him through. The smell of his burning flesh rose to sicken me. He was dead. I dropped his body. Carter shoved me into the chart-room.

In the small, steel-lined room, Carter and I slid the door closed. We were alone here. The thing had come so quickly it had taken Captain Carter, like us all, wholly unawares. We had anticipated spying eavesdroppers, but not this open brigandage. No more than a minute or two had passed since Miko’s siren in his stateroom had given the signal for the attack. Carter had been in the chart-room. Blackstone was in the turret. At the outbreak of confusion, Carter dashed out to see Hahn releasing Johnson from the cage. From the forward chart-room window now I could see where Hahn with a torch had broken the cage-seal. The torch lay on the deck. There had been an exchange of shots; Carter’s arm was paralyzed; Johnson and Hahn had escaped.

Carter was as confused as I. There had simultaneously been an encounter up in the turret. Blackstone and the course-master were killed. The lookout had been shot from his post in the forward observatory. His body dangled now, twisted half in and half out of his window.

WE could see several of Miko’s men—erstwhile members of our crew and steward-corps—scurrying from the turret along the upper bridges toward the dark and silent helio-room. Snap was up there. But was he? The helio-room glowed suddenly with dim light, but there was no evidence of a fight there. The fighting seemed mostly below the deck, down in the hull-corridors. A blended horror of sounds came up to us. Screams, shouts, and the hissing and snapping of ray weapons. Our crew—such of them as were loyal—were making a stand down below. But it was brief. Within a minute it died away. The passengers, amidships in the superstructure, were still shouting. Then above them Miko’s roar sounded.

“Be quiet! Go in your rooms—you will not be harmed.”

The brigands in these few minutes were in control of the ship. All but this little chart-room, where, with most of the ship’s weapons, Carter and I were intrenched.

“God, Gregg, that this should come upon us!”

Carter was fumbling with the chart-room weapons. “Here, Gregg, help me. What have you got? Heat-ray? That’s all I had ready.”

It struck me then as I helped him make the connections that Carter in this crisis was at best an inefficient commander. His red face had gone splotchy purple; his hands were trembling. Skilled as captain of a peaceful liner, he was at a loss now. Nor could I blame him. It is easy to say we might have taken warning, done this or that, and come triumphant through this attack. But only the fool looks backward and says, “I would have done better.”

I TRIED to summon my wits. The ship was lost to us, unless Carter and I could do something. Our futile weapons! They were all here—four or five heat-ray hand projectors that could send a pencil-ray a hundred feet or so. I shot one diagonally up at the turret where Johnson was leering down at our rear window, but he saw my gesture and dropped back out of sight. The heat-beam flashed harmlessly up and struck the turret roof. Then across the turret window came a sheen of radiance—an electro-barrage. And behind it, Hahn’s suave, evil face appeared. He shouted down:

“We have orders to spare you, Gregg Haljan—or you would have been killed long ago!”

My answering shot hit his barrage with a shower of sparks, behind which he stood unmoved.

Carter handed me another weapon. “Gregg, try this.”

I levelled the old explosive bullet projector; Carter crouched beside me. But before I could press the trigger, from somewhere down the starlit deck an electro-beam hit me. The little rifle exploded, burst its breech. I sank back to the floor, tingling from the shock of the hostile current. My hands were blackened from the exploding powder.

Carter seized me. “No use! Hurt?”

“No.”

THE stars through the dome-windows were swinging. A long swing—the shadows and starlit patches on the deck were all shifting. The Planetara was turning. The heavens revolved in a great round sweep of movement, then settled as we took our new course. Hahn at the turret controls had swung us. The earth and the sun showed over our bow quarter. The sunlight mingled red-yellow with the brilliant starlight. Hahn’s signals were sounding; I heard them answered from the mechanism rooms down below. Brigands there—in full control. The gravity plates were being set to the new positions; we were on our new course. Headed a point or two off the Earth-line. Not headed for the moon? I wondered.

Carter and I were planning nothing. What was there to plan? We were under observation. A Martian paralyzing ray—or electronic beam, far more deadly than our own puny police weapons—would have struck us the instant we tried to leave the chart-room.

My swift-running thoughts were interrupted by a shout from down the deck. At a corner of the cabin superstructure some fifty feet from our windows the figure of Miko appeared. A barrage-radiance hung around him like a shimmering mantle. His voice sounded:

“Gregg Haljan, do you yield?”

Carter leaped up from where he and I were crouching. Against all reason of safety he leaned from the low window, waving his hamlike fist.

“Yield? No! I am in command here, you pirate! Brigand—murderer!”

I PUSHED him back. “Careful!”

He was spluttering, and over it Miko’s sardonic laugh sounded. “Very well—but you will talk? Shall we argue about it?”

I stood up. “What do you want to say, Miko?”

Behind him the tall, thin figure of his sister showed. She was plucking at him. He turned violently.

“I won’t hurt him! Gregg Haljan—is this a truce? You will not shoot?” He was shielding Moa.

“No,” I called. “For a moment, no. A truce. What is it you want to say?”

I could hear the babble of passengers who were herded in the cabin with brigands guarding them. George Prince, bareheaded, but shrouded in his cloak, showed in a patch of light behind Moa. He looked my way and then retreated into the lounge archway.

Miko called, “You must yield. We want you, Haljan.”

“No doubt,” I jeered.

“Alive. It is easy to kill you.”

I COULD not doubt that. Carter and I were little more than rats in a trap, here in the chart-room. But Miko wanted to take me alive: that was not so simple. He added persuasively:

“We want you to help us navigate. Will you?”

“No.”

“Will you help us, Captain Carter? Tell your cub, this Haljan, to yield. You are fools. We understand that Haljan has been handling the ship’s mathematics. Him we need most.”

Carter roared: “Get back from there! This is no truce!”

I shoved aside his levelled bullet-projector. “Wait a minute!” I called to Miko. “Navigate—where?”

“Oh,” he retorted, “that is our business, not yours. When you lay down your weapons and come out of there, I will give you the course.”

“Back to the earth?” I suggested.

I could fancy him grinning behind the sheen of his barrage at my question.

“The earth? Yes—shall we go there? Give me your orders, Gregg Haljan. Of course I will obey them.”

His sardonic words were interrupted. And I realized that all this parley was a ruse of Miko’s to take me alive. He had made a gesture. Hahn, watching from the turret window, doubtless flashed a signal down to the hull-corridors. The magnetizer control under the chart-room was altered, our artificial gravity cut off. I felt the sudden lightness; I gripped the window casement and clung. Carter was startled into incautious movement. It flung him out into the center of the chart-room, his arms and legs grotesquely flailing.

And across the chart-room, in the opposite window, I felt rather than saw the shape of something. A figure—almost invisible, but not quite—was trying to climb in! I flung the empty rifle I was holding. It hit something solid in the window; in a flare of sparks a black-hooded figure materialized. A man climbing in! His weapon spat. There was a tiny electronic flash, deadly silent. The intruder had shot at Carter; struck him. Carter gave one queer scream. He had floated to the floor; his convulsive movement when he was hit hurled him to the ceiling. His body struck, twitched; bounced back and sank inert on the floor-grid almost at my feet.

I clung to the casement. Across the space of the weightless room the hooded intruder was also clinging. His hood fell back. It was Johnson. He leered at me.

“Killed him, the bully! Well, he deserved it. Now for you, Mr. Third Officer Haljan!”

But he did not dare fire at me—Miko had forbidden it. I saw him reach under his robe, doubtless for a low-powered paralyzing ray such as Miko already had used on me. But he never got it out. I had no weapon within reach. I leaned into the room, still holding the casement, and doubled my legs under me. I kicked out from the window.

The force catapulted me across the space of the room like a volplane. I struck the purser. We gripped. Our locked, struggling bodies bounced out into the room. We struck the floor, surged up like balloons to the ceiling, struck it with a flailing arm or a leg and floated back.

GROTESQUE, abnormal combat! Like fighting in weightless water. Johnson clutched his weapon, but I twisted his wrist, held his arm outstretched so that he could not aim it. I was aware of Miko’s voice shouting on the deck outside.

Johnson’s left hand was gouging at my face, his fingers plucking at my eyes. We lunged down to the floor, then up again, close to the ceiling.

I twisted his wrists. He dropped the weapon and it sank away. I tried to reach it, but could not. Then I had him by the throat. I was stronger than he, and more agile. I tried choking him, his thick bull-neck within my fingers. He kicked, scrambled, tore and gouged at me. Tried to shout, but it ended in a gurgle. And then, as he felt his breath stopped, his hands came up in an effort to tear mine loose.

We sank again to the floor. We were momentarily upright. I felt my feet touch. I bent my knees. We sank further.

And then I kicked violently upward. Our locked bodies shot to the ceiling. Johnson’s head was above me. It struck the steel roof of the chart-room. A violent blow. I felt him go suddenly limp. I cast him off, and, doubling my body, I kicked at the ceiling. It sent me diagonally downward to the window, where I clung and regained stability.

And I saw Miko standing on the deck with a weapon levelled at me!

CHAPTER XIII
The Torture

"HALJAN! Yield or I’ll fire! Moa, give me the smaller one. This cursed—”

He had in his hand too large a projector. Its ray would kill me. If he wanted to take me alive, he would not fire. I chanced it.

“No!”

I tried to draw myself beneath the window. An automatic bullet projector was on the floor where Carter had dropped it. I pulled myself down. Miko did not fire. I reached the revolver. The dead bodies of the captain and purser had drifted together on the floor in the center of the room.

I hitched myself back to the window. With upraised weapon I gazed cautiously out. Miko had disappeared. The deck within my line of vision was empty.

But was it? Something told me to beware. I clung to the casement, ready upon the instant to shove myself down. There was a movement in a shadow along the deck. Then a figure rose up.

“Don’t fire, Haljan!”

The sharp command, half appeal, stopped the pressure of my finger on the trigger of the automatic. It was the tall lanky Englishman, Sir Arthur Coniston, as he called himself. So he too was one of Miko’s band! The light through a dome-window fell full on him.

“If you fire, Haljan, and kill me—Miko will kill you then, surely.”

From where he had been crouching he could not command my window. But now, upon the heels of his placating words, he abruptly shot. The low-powered ray, had it struck, would have felled me without killing. But it went over my head as I dropped. Its aura made my senses reel.

Coniston shouted, “Haljan!”

I DID not answer. I wondered if he would dare approach to see if I had been hit. A minute passed. Then another. I thought I heard Miko’s voice on the deck outside. But it was an aerial, microscopic whisper close beside me.

“We see you, Haljan! You must yield!”

Their eavesdropping vibrations, with audible projection, were upon me. I retorted aloud.

“Come and get me! You cannot take me alive.”

I do protest if this action of mine in the chart-room may seem bravado. I had no wish to die. There was within 346 me a very healthy desire for life. But I felt, by holding out, that some chance might come wherewith I might turn events against these brigands. Yet reason told me it was hopeless. Our loyal members of the crew were killed, no doubt. Captain Carter and Balch were killed. The lookouts and Course-masters also. And Blackstone.

There remained only Dr. Frank and Snap. Their fate I did not yet know. And there was George Prince. He, perhaps, would help me if he could. But, at best, he was a dubious ally.

“You are very foolish, Haljan,” murmured the projection of Miko’s voice. And then I heard Coniston:

“See here, why would not a hundred pounds of gold-leaf tempt you? The code-words which were taken from Johnson—I mean to say, why not tell us where they are?”

So that was one of the brigands new difficulties! Snap had taken the code-word sheet, that time we sealed the purser in the cage.

I said, “You’ll never find them. And when a police ship sights us, what will you do then?”

The chances of a police ship were slim indeed, but the brigands evidently did not know that. I wondered again what had become of Snap. Was he captured—or still holding them off?

I was watching my windows; for at any moment, under cover of this talk, I might be assailed.

GRAVITY came suddenly to the room. Miko’s voice said. “We mean well by you, Haljan. There is your normality. Join us. We need you to chart our course.”

“And a hundred pounds of gold-leaf,” urged Coniston. “Or more. Why, this treasure—”

I could hear an oath from Miko. And then his ironic voice: “We will not bother you, Haljan. There is no hurry. You will be hungry in good time. And sleepy. Then we will come and get you. And a little acid will make you think differently about helping us....”

His vibrations died away. The pull of gravity in the room was normal. I was alone in the dim silence, with the bodies of Carter and Johnson lying huddled on the grid. I bent to examine them. Both were dead.

My isolation was no ruse this time. The outlaws made no further attack. Half an hour passed. The deck outside, what I could see of it, was vacant. Balch lay dead close outside the chart-room door. The bodies of Blackstone and the Course-master had been removed from the turret window. A forward lookout—one of Miko’s men—was on duty in the nearby tower. Hahn was at the turret controls. The ship was under orderly handling, heading back upon a new course. For the Earth? Or the Moon? It did not seem so.

I found, in the chart-room, a Benson curve-light projector which poor Captain Carter had very nearly assembled. I worked on it, trained it through my rear window, along the empty deck; bent it into the lounge archway. Upon my grid the image of the lounge interior presently focused. The passengers in the lounge were huddled in a group. Disheveled, frightened, with Moa standing watching them. Stewards were serving them with a meal.

UPON a bench, bodies were lying. Some were dead. I saw Rance Rankin. Others were evidently only injured. Dr. Frank was moving among them, attending them. Venza was there, unharmed. And I saw the gamblers, Shac and Dud, sitting white-faced, whispering together. And Glutz’s little be-ribboned, be-curled figure on a stool.

George Prince was there, standing against the walls shrouded in his mourning cloak, watching the scene with alert, roving eyes. And by the opposite doorway, the huge towering figure of Miko stood on guard. But Snap was missing.

A brief glimpse. Miko saw my Benson-light. I could have equipped a heat-ray, and fired along the curved Benson-light into that lounge. But Miko gave me no time.

He slid the lounge door closed, and Moa leaped to close the one on my side. My light was cut off; my grid showed only the blank deck and door.

Another interval. I had made plans. Futile plans! I could get into the turret perhaps, and kill Hahn. I had the invisible cloak which Johnson was wearing. I took it from his body. Its mechanism could be repaired. Why, with it I could creep about the ship, kill these brigands one by one perhaps. George Prince would be with me. The brigands who had been posing as the stewards and crew-members were unable to navigate; they would obey my orders. There were only Miko, Coniston and Hahn to kill.

Futile plans! From my window I could gaze up to the helio-room. And now abruptly I heard Snap’s voice:

“No! I tell you—no!”

And Miko: “Very well. We will try this.”

So Snap was captured, but not killed. Relief swept me. He was in the helio-room, and Miko was with him. But my relief was short-lived.

AFTER a brief interval there came a moan from Snap. It floated down from the silence overhead. It made me shudder.

My Benson-beam shot into the helio window. It showed me Snap lying there on the floor. He was bound with wire. His torso had been stripped. His livid face was ghastly plain in my light.

Miko was bending over him. Miko with a heat-cylinder no longer than a finger. Its needle-beam played upon Snap’s naked chest. I could see the gruesome little trail of smoke rising; and as Snap twisted and jerked, there on his flesh was the red and blistered trail of the violet-hot ray.

“Now will you tell?”

“No!”

Miko laughed. “No? Then I shall write my name a little deeper....”

A black scar now—a trail etched in the quivering flesh.

“Oh!—” Snap’s face went white as chalk as he pressed his lips together.

“Or a little acid? This fire-writing does not really hurt? Tell me what you did with those code-words!”

“No!”

In his absorption Miko did not notice my light. Nor did I have the wit to try and fire along it. I was trembling. Snap under torture!

As the beam went deeper, Snap suddenly screamed. But he ended, “No! I will send—no message for you—”

It had been only a moment. In the chart-room window beside me again a figure appeared! No image. A solid, living person, undisguised by any cloak of invisibility. George Prince had chanced my fire and had crept up upon me.

“Haljan! Don’t attack me.”

I DROPPED my light connections. As impulsively I stood up, I saw through the window the figure of Coniston on the deck watching the result of Prince’s venture.

“Haljan—yield.”

Prince no more than whispered it. He stood outside on the deck; the low window casement touched his waist. He leaned over it.

“He’s torturing Snap! Call out that you will yield.”

The thought had already been in my mind. Another scream from Snap chilled me with horror. I shouted,

“Miko! Stop!”

I rushed to the window and Prince gripped me.

“Louder!”

I called louder. “Miko! Stop!” My upflung voice mingled with Snap’s agony of protest. Then Miko heard me. His head and shoulders showed up there at the helio-room oval.

“You, Haljan?”

Prince shouted, “I have made him yield. He will obey you if you stop that torture.”

I think that poor Snap must have fainted. He was silent. I called, “Stop! I will do what you command.”

Miko jeered, “That is good. A bargain, if you and Dean obey me. Disarm him, Prince, and bring him out.”

MIKO moved back into the helio-room. On the deck Coniston was advancing, but cautiously, mistrustful of me.

“Gregg.”

George Prince flung a leg over the casement and leaped lightly into the dim chart-room. His small slender figure stood beside me, clung to me.

“Gregg.”

A moment, while we stood there together. No ray was upon us. Coniston could not see us, nor could he hear our whispers.

“Gregg.”

A different voice; its throaty, husky quality gone. A soft pleading. “Gregg—

“Gregg, don’t you know me? Gregg, dear....”

Why, what was this? Not George Prince? A masquerader, yet so like George Prince.

“Gregg, don’t you know me?”

Clinging to me. A soft touch upon my arm. Fingers, clinging. A surge of warm, tingling current was flowing between us.

My sweep of instant thoughts. A speck of human Earth-dust, falling free. That was George Prince, who had been killed. George Prince’s body, disguised by the scheming Carter and Dr. Frank, buried in the guise of his sister. And this black-robed figure who was trying to help us—

“Anita! Dear God! Anita, darling! Anita!”

“Gregg, dear one!”

“Anita! Dear God!”

MY arms went around her, my lips pressed hers, and felt her tremulous, eager answer.

“Gregg, dear.”

“Anita, you!”

The form of Coniston showed at our window. She cast me off. She said, with her throaty swagger of assumed masculinity:

“I have him, Sir Arthur. He will obey us.”

I sensed her warning glance. She shoved me toward the window. She said ironically, “Have no fear, Haljan. You will not be tortured, you and Dean, if you obey our commands.”

Coniston gripped me. “You fool! You caused us a lot of trouble, didn’t you? Move along there!”

He jerked me roughly through the window. Marched me the length of the deck. Out to the stern-space; opened the door of my cubby; flung me in and sealed the door upon me.

“Miko will come presently.”

I stood in the darkness of my tiny room, listening to his retreating footsteps. But my mind was not on him....

All the Universe in that instant had changed for me. Anita was alive!

CHAPTER XIV
The Brigand Leader

THE giant Miko stood confronting me. He slid my cubby door closed behind him. He stood with his head towering close against my ceiling. His cloak was discarded. In his leather clothes, and with his clanking sword-ornament, his aspect carried the swagger of a brigand of old. He was bareheaded; the light from one of my tubes fell upon his grinning, leering gray face.

"So, Gregg Haljan? You have come to your senses at last. You do not wish me to write my name upon your chest? I would not have done that to Dean; he forced me. Sit back."

I had been on my bunk. I sank back at the gesture of his huge hairy arm. His forearm was bare now; the sear of a burn on it was plain to be seen. He remarked my gaze.

"True. You did that, Haljan, in Great-New York. But I bear you no malice. I want to talk to you now."

He cast about for a seat, and took the little stool which stood by my desk. His hand held a small cylinder of the Martian paralyzing ray; he rested it beside him on the desk.

"Now we can talk."

I remained silent. Alert. Yet my thoughts were whirling. Anita was alive. Masquerading now as her brother. And, with the joy of it, came a shudder. Above everything, Miko must not know.

"A great adventure we are upon, Haljan."

MY thoughts came back. Miko was talking with an assumption of friendly comradeship. "All is well—and we need you, as I have said before. I am no fool. I have been aware of everything that went on aboard this ship. You, of all the officers, are most clever at the routine mathematics. Is that so?"

"Perhaps," I said.

"You are modest." He fumbled at a pocket of his jacket, produced a scroll-sheaf. I recognized it: Blackstone's figures; the calculation Blackstone roughly made of the elements of the asteroid we had passed.

"I am interested in these," Miko went on. "I want you to verify them. And this." He held up another scroll. "This is the calculation of our present position. And our course. Hahn claims he is a navigator. We have set the ship's gravity plates—see, like this—"

He handed me the scrolls; he watched me keenly as I glanced over them.

"Well?" I said.

"You are sparing of words, Haljan. By the devils of the airways, I could make you talk! But I want to be friendly."

I HANDED him back the scrolls. I stood up; I was almost within reach of his weapon, but with a sweep of his great arm he abruptly knocked me back to my bunk.

"You dare?" Then he smiled. "Let us not come to blows!"

"No," I said. I returned his smile. In truth, physical violence could get me nothing in dealing with this fellow. I would have to try guile. And I saw now that his face was flushed and his eyes unnaturally bright. He had been drinking alcolite; not enough to befuddle him—but enough to make him triumphantly talkative.

"Hahn may not be much of a mathematician," I suggested. "But there is your Sir Arthur Coniston." I managed a sarcastic grin. "Is that his name?"

"Almost. Haljan, will you verify these figures?"

"Yes. But why? Where are we going?"

He laughed. "You are afraid I will not tell you! Why should I not? This great adventure of mine is progressing perfectly. A tremendous stake, Haljan. A hundred millions of dollars in gold-leaf; there will be fabulous riches for us all, when that radium ore is sold for a hundred million in gold-leaf."

"But where are we going?"

"To that asteroid," he said abruptly. "I must get rid of these passengers. I am no murderer."

WITH half a dozen killings in the recent fight this was hardly convincing. But he was obviously wholly serious. He seemed to read my thoughts.

"I kill only when necessary. We will land upon the asteroid. A perfect place to maroon the passengers. Is it not so? I will give them the necessities of life. They will be able to signal. And in a month or so, when we are safely finished with our adventure, a police ship no doubt will rescue them."

"And then, from the asteroid," I suggested, "we are going—"

"To the Moon, Haljan. What a clever guesser you are! Coniston and Hahn are calculating our course. But I have no great confidence in them. And so I want you."

"You have me."

"Yes. I have you. I would have killed you long ago—I am an impulsive fellow—but my sister restrained me."

He gazed at me slyly. "Moa seems strangely to like you, Haljan."

"Thanks," I said. "I'm flattered."

"She still hopes I may really win you to join us," he went on. "Gold-leaf is a wonderful thing; there would be plenty for you in this affair. And to be rich, and have the love of a woman like Moa...."

He paused. I was trying cautiously to gauge him, to get from him all the information I could. I said, with another smile, "That is premature, to talk of Moa. I will help you chart your course. But this venture, as you call it, is dangerous. A police-ship—"

"There are not many," he declared. "The chances of us encountering one is very slim." He grinned at me. "You know that as well as I do. And we now have those code pass-words—I forced Dean to tell me where he had hidden them. If we should be challenged, our pass-word answer will relieve suspicion."

"The Planetara," I objected, "being overdue at Ferrok-Shahn, will cause alarm. You'll have a covey of patrol-ships after you."

"That will be two weeks from now," he smiled. "I have a ship of my own in Ferrok-Shahn. It lies there waiting now, manned and armed. I am hoping that, with Dean's help, we may be able to flash it a signal. It will join us on the Moon. Fear not for the danger, Haljan. I have great interests allied with me in this thing. Plenty of money. We have planned carefully."

HE was idly fingering his cylinder; his gaze roved me as I sat docile on my bunk. "Did you think George Prince was a leader of this? A mere boy. I engaged him a year ago—his knowledge of ores is valuable."

My heart was pounding, but I strove not to show it. He went on calmly.

"I told you I am impulsive. Half a dozen times I have nearly killed George Prince, and he knows it." He frowned. "I wish I had killed him, instead of his sister. That was an error."

There was a note of real concern in his voice. Did he love Anita Prince? It seemed so.

He added, "That is done—nothing can change it. George Prince is helpful to me. Your friend Dean is another. I had trouble with him, but he is docile now."

I said abruptly, "I don't know whether your promise means anything or not, Miko. But George Prince said you would use no more torture."

"I won't. Not if you and Dean obey me."

"You tell Dean I have agreed to that. You say he gave you the code-words we took from Johnson?"

"Yes. There was a fool! That Johnson! You blame me, Haljan, for the killing of Captain Carter? You need not. Johnson offered to try and capture you. Take you alive. He killed Carter because he was angry at him. A stupid, vengeful fool! He is dead, and I am glad of it."

MY mind was on Miko's plans. I ventured. "This treasure on the Moon—did you say it was on the Moon?"

"Don't be an idiot," he retorted. "I know as much about Grantline as you do."

"That's very little."

"Perhaps."

"Perhaps you know more, Miko. The Moon is a big place. Where, for instance, is Grantline located?"

I held my breath. Would he tell me that? A score of questions—vague plans—were in my mind. How skilled at mathematics were these brigands? Miko, Hahn, Coniston—could I fool them? If I could learn Grantline's location on the Moon, and keep the Planetara away from it. A pretended error of charting. Time lost—and perhaps Snap could find an opportunity to signal Earth, get help.

Miko answered my question as bluntly as I asked it. "I don't know where Grantline is located. But we will find out. He will not suspect the Planetara. When we get close to the Moon, we will signal and ask him. We can trick him into telling us. You think I do not know what is on your mind, Haljan? There is a secret code of signals arranged between Dean and Grantline. I have forced Dean to confess it. Without torture! Prince helped me in that. He persuaded Dean not to defy me. A very persuasive fellow, George Prince. More diplomatic than I am, I give him credit."

I strove to hold my voice calm. "If I should join you, Miko—my word, if I ever gave it, you would find dependable—I would say George Prince is very valuable to us. You should rein your temper. He is half your size—you might some time, without intention do him injury."

HE laughed. "Moa says so. But have no fear—"

"I was thinking," I persisted, "I'd like to have a talk with George Prince."

Ah, my pounding, tumultuous heart! But I was smiling calmly. And I tried to put into my voice a shrewd note of cupidity. "I really know very little about this treasure, Miko. If there were a million or two of gold-leaf in it for me—"

"Perhaps there would be."

"I was thinking. Suppose you let me have a talk with Prince? I have some knowledge of radium ores. His skill and mine—a calculation of what Grantline's treasure may really be. You don't know; you are only assuming."

I paused. Whatever may have been in Miko's mind I cannot say. But abruptly he stood up. I had left my bunk, but he waved me back.

"Sit down. I am not like Moa. I would not trust you just because you protested you would be loyal." He picked up his cylinder. "We will talk again." He gestured to the scrolls he had left upon my desk. "Work on those. I will judge you by the results."

He was no fool, this brigand leader.

"Yes," I agreed. "You want a true course now to the asteroid?"

"Yes. I will get rid of these passengers. Then we will plan further. Do your best, Haljan—no error! By the Gods, I warn you I can check up on you!"

I said meekly, "Very well. But you ask Prince if he wants my calculations of Grantline's ore-body."

I shot Miko a foxy look as he stood by my door. I added, "You think you are clever. There is plenty you don't know. Our first night out from the Earth—Grantline's signals—didn't it ever occur to you that I might have some figures on his treasure?"

It startled him. "Where are they?"

I tapped my forehead. "You don't suppose I was foolish enough to record them. You ask Prince if he wants to talk to me. A high thorium content in ore—you ask Prince. A hundred millions, or two hundred. It would make a big difference, Miko."

"I will think about it." He backed out and sealed the door upon me once again.

BUT Anita did not come. I verified Hahn's figures, which were very nearly correct. I charted a course for the asteroid; it was almost the one which had been set.

Coniston came for my results. "I say, we are not so bad as navigators, are we? I think we're jolly good, considering our inexperience. Not bad at all, eh?"

"No."

I did not think it wise to ask him about Prince.

"Are you hungry, Haljan?" he demanded.

"Yes."

A steward came with a meal. The saturnine Hahn stood at my door with a weapon upon me while I ate. They were taking no chances—and they were wise not to.

The day passed. Day and night, all the same of aspect here in the starry vault of Space. But with the ship's routine it was day.

And then another time of sleep. I slept, fitfully, worrying, trying to plan. Within a few hours we would be nearing the asteroid.

The time of sleep was nearly passed. My chronometer marked five A. M. of our original Earth starting time. The seal of my cubby door hissed. The door slowly, opened.

Anita!

She stood there with her cloak around her. A distance away on the shadowed deck-space Coniston was loitering.

"Anita!" I whispered it.

"Gregg, dear!"

She turned and gestured to the watching brigand. "I will not be long, Coniston."

She came in and half closed the door upon us, leaving it open enough so that we could make sure that Coniston did not advance.

I stepped back where he could not see us.

"Anita!"

She flung herself into my opened arms.

CHAPTER XV
The Masquerader

A MOMENT when beyond all thought of the nearby brigand—or the possibility of an eavesdropping ray trained now upon my little cubby—a moment while Anita and I held each other; and whispered those things which could mean nothing to the world, but which were all the world to us.

Then it was she whose wits brought us back from the shining fairyland of our love, into the sinister reality of the Planetara.

"Gregg, if they are listening—"

I pushed her away. This brave little masquerader! Not for my life, or for all the lives on the ship, would I consciously have endangered her.

"But the ore," I said aloud. "There was, in Grantline's message—See here, Prince."

Coniston was too far away on the deck to hear us. Anita went to my door again and waved at him reassuringly. I put my ear to the door opening, and listened at the space across the grid of the ventilator over my bunk. The hum of a vibration would have been audible at those two points. But there was nothing.

"It's all right," I whispered. "Anita—not you who was killed! I can hardly realize it now. Not you whom they buried yesterday morning."

We stood and whispered, and she clung to me—so small beside me. With the black robe thrown aside, it seemed that I could not miss the curves of her woman's figure. A dangerous game she was playing. Her hair had been cut short to the base of her neck, in the fashion of her dead brother. Her eyelashes had been clipped; the line of her brows altered. And now, in the light of my ray tube as it shone upon her earnest face, I could remark other changes. Glutz, the little beauty specialist, was in this secret. With plastic skill he had altered the set of her jaw with his wax—put masculinity there.

She was whispering: "It was—was poor George whom Miko shot."

I HAD now the true version of what had occurred. Miko had been forcing his wooing upon Anita. George Prince was a weakling whose only good quality was a love for his sister. Some years ago he had fallen into evil ways. Been arrested, and then discharged from his position with the Federated Radium Corporation. He had taken up with evil companions in Great-New York. Mostly Martians. And Miko had met him. His technical knowledge, his training with the Federated Corporation, made him valuable to Miko's enterprise. And so Prince had joined the brigands.

Of all this, Anita had been unaware. She had never liked Miko. Feared him. And it seemed that the Martian had some hold upon her brother, which puzzled and frightened Anita.

Then Miko had fallen in love with her. George had not liked it. And that night on the Planetara, Miko had come and knocked upon Anita's door. Incautiously she opened it; he forced himself in. And when she repulsed him, struggled with him, George had been awakened.

She was whispering to me now. "My room was dark. We were all three struggling. George was holding me—the shot came—and I screamed."

And Miko had fled, not knowing whom his shot had hit in the darkness.

"And when George died, Captain Carter wanted me to impersonate him. We planned it with Dr. Frank, to try and learn what Miko and the others were doing. Because I never knew that poor George had fallen into such evil things."

I COULD only hold her thankfully in my arms. The lost what-might-have-been seemed coming back to us.

"And they cut my hair, Gregg, and Glutz altered my face a little, and I did my best. But there was no time—it came upon us so quickly."

And she whispered, "But I love you, Gregg. I want to be the first to say it: I love you—I love you."

But we had the sanity to try and plan.

"Anita, when you go back, tell Miko we discussed radium ores. You'll have to be careful, clever. Don't say too much. Tell him we estimate the treasure at a hundred and thirty millions."

I told her what Miko had vouchsafed me of his plans. She knew all that. And Snap knew it. She had had a few moments alone with Snap. Gave me now a message from him:

"We'll pull out of this, Gregg."

With Snap she had worked out a plan. There were Snap and I; and Shac and Dud Ardley, upon whom we could doubtless depend. And Dr. Frank. Against us were Miko and his sister; and Coniston and Hahn. Of course there were the members of the crew. But we were numerically the stronger when it came to true leadership. Unarmed and guarded now. But if we could break loose—recapture the ship....

I sat listening to Anita's eager whispers. It seemed feasible. Miko did not altogether trust George Prince; Anita was now unarmed.

"But I can make opportunity! I can get one of their ray cylinders, and an invisible cloak equipment."

That cloak—it had been hidden in Miko's room when Carter searched for it in A20—was now in the chart-room by Johnson's body. It had been repaired now; Anita thought she could get possession of it.

WE worked out the details of the plan. Anita would arm herself, and come and release me. Together, with a paralyzing ray, we could creep aboard the ship, overcome these brigands one by one. There were so few of the leaders. With them felled, and with us in control of the turret and the helio-room we could force the crew to stay at their posts. There were, Anita said, no navigators among Miko's crew. They would not dare oppose us.

"But it should be done at once, Anita. In a few hours we will be at the asteroid."

"Yes. I will go now—try and get the weapons."

"Where is Snap?"

"Still in the helio-room. One of the crew guards him."

Coniston was roaming the ship; he was still loitering on the deck, watching our door. Hahn was in the turret. The morning watch of the crew were at their posts in the hull-corridors; the stewards were preparing a morning meal. There were nine members of subordinates altogether, Anita had calculated. Six of them were in Miko's pay; the other three—our own men who had not been killed in the fighting—had joined the brigands.

"And Dr. Frank, Anita?"

He was in the lounge. All the passengers were herded there, with Miko and Moa alternating on guard.

"I will arrange it with Venza," Anita whispered swiftly. "She will tell the others. Dr. Frank knows about it now. He thinks it can be done."

THE possibility of it swept me anew. The brigands were of necessity scattered singly about the ship. One by one, creeping under cover of an invisible cloak, I could fell them, and replace them without alarming the others. My thoughts leaped to it. We would strike down the guard in the helio-room. Release Snap. At the turret we could assail Hahn, and replace him with Snap.

Coniston's voice outside broke in upon us. "Prince."

He was coming forward. Anita stood in the doorway. "I have the figures, Coniston. By God, this Haljan is with us! And clever! We think it will total a hundred and thirty millions. What a stake!"

She whispered, "Gregg, dear—I'll be back soon. We can do it—be ready."

"Anita—be careful of yourself! If they should suspect you...."

"I'll be careful. In an hour, Gregg, or less, I'll come back. All right, Coniston. Where is Miko? I want to see him. Stay where you are, Haljan! All in good time Miko will trust you with your liberty. You'll be rich like us all, never fear."

She swaggered out upon the deck, waved at the brigand, and banged my cubby door in my face.

I sat upon my bunk. Waiting. Would she come back? Would she be successful?

CHAPTER XVI
In the Blue-lit Corridor

SHE came. I suppose it was no more than an hour: it seemed an eternity of apprehension. There was the slight hissing of the seal of my door. The panel slid. I had leaped from my bunk where in the darkness I was lying tense.

"Prince?" I did not dare say, "Anita."

"Gregg."

Her voice. My gaze swept the deck as the panel opened. Neither Coniston nor anyone else was in sight, save Anita's dark-robed figure which came into my room.

"You got it?" I asked her in a low whisper.

I held her for an instant, kissed her. But she pushed me away with quick hands.

"Gregg, dear—"

She was breathless. My kisses, and the tenseness of what lay before us were to blame.

"Gregg, see, I have it. Give us a little light—we must hurry!"

In the blue dimness I saw that she was holding one of the Martian cylinders. The smallest size; it would paralyze, but not kill.

"Only one, Anita?"

"Yes. I had it before, but Miko took it from me. It was in his room. And this—"

The invisible cloak. We laid it on my grid, and I adjusted its mechanism. A cloak of the reflecting-absorbing variety.¹

1: The principle of this invisible cloak involves the use of an electronized fabric. All color is absorbed. The light rays reflected to the eye of the observer thus show an image of empty blackness. There is also created about the cloak a magnetic field which by natural laws bends the rays of light from objects behind it. This principle of the natural bending of light when passing through a magnetic field was first recognized by Albert Einstein, a scientist of the Twentieth century. In the case of this invisible cloak, the bending light rays, by making visible what was behind the cloak's blackness, thus destroyed its solid black outline and gave a pseudo-invisibility which was fairly effective under favorable conditions.

I DONNED it, and drew its hood, and threw on its current.

"All right, Anita?"

"Yes."

"Can you see me?"

"No." She stepped back a foot or two further. "Not from here. But you must let no one approach too close."

Then she came forward, put out her hand, fumbled until she found me.

It was our plan to have me follow her out. Anyone observing us would see only the robed figure of the supposed George Prince, and I would escape notice.

The situation about the ship was almost unchanged. Anita had secured the weapon and the cloak and slipped away to my cubby without being observed.

"You're sure of that?"

"I think so, Gregg. I was careful."

Moa was now in the lounge, guarding the passengers. Hahn was asleep in the chart-room; Coniston was in the turret. Coniston would be off duty presently, Anita said, with Hahn taking his place. There were look-outs in the forward and stern watch-towers, and a guard upon Snap in the helio-room.

"Is he inside the room, Anita?"

"Snap? Yes."

"No—the guard."

"No. He was sitting upon the spider bridge at the door."

THIS was unfortunate. That guard could see all the deck clearly. He might be suspicious of George Prince wandering around; it would be difficult to get near enough to assail him. This cylinder, I knew, had an effective range of only some twenty feet.

Anita and I were swiftly whispering. It was necessary now to decide exactly what we were to do; once under observation outside, there must be no hesitation, no fumbling.

"Coniston is sharpest, Gregg. He will be the hardest to get near."

The languid-spoken Englishman was the one Anita most feared. His alert eyes seemed to miss nothing. Perhaps he was suspicious of this George Prince—Anita thought so.

"But where is Miko?" I whispered.

The brigand leader had gone below a few moments ago, down into the hull-corridor. Anita had seized the opportunity to come to me.

"We can attack Hahn in the chart-room first," I suggested. "And get the other weapons. Are they still there?"

"Yes. But Gregg, the forward deck is very bright."

We were approaching the asteroid. Already its light like a brilliant moon was brightening the forward deck-space. It made me realize how much haste was necessary.

We decided to go down into the hull-corridors. Locate Miko. Fell him, and hide him. His non-appearance back on deck would very soon throw the others into confusion, especially now with our impending landing upon the asteroid. And under cover of this confusion we would try and release Snap.

We had been arguing no more than a minute or two. We were ready. Anita slid my door wide. She stepped through, with me soundlessly scurrying after her. The empty, silent deck was alternately dark with shadow-patches and bright with blobs of starlight. A sheen of the Sun's corona was mingled with it; and from forward came the radiance of the asteroid's mellow silver glow.

ANITA turned to seal my door; within my faintly humming cloak I stood beside her. Was I invisible in this light? Almost directly over us, close under the dome, the look-out sat in his little tower. He gazed down at Anita.

Amidships, high over the cabin superstructure, the helio-room hung dark and silent. The guard on its bridge was visible. He, too, looked down.

A tense instant. Then I breathed again. There was no alarm. The two guards answered Anita's gesture.

Anita said aloud into my empty cubby: "Miko will come for you presently, Haljan. He told me to tell you that he wants you at the turret controls to land us on the asteroid."

She finished sealing my door and turned away; started forward along the deck. I followed. My steps were soundless in my elastic-bottomed shoes. Anita swaggered with a noisy tread. Near the door of the smoking room a small incline passage led downward. We went into it.

The passage was dimly blue-lit. We descended its length, came to the main corridor, which ran the length of the hull. A vaulted metal passage, with doors to the control rooms opening from it. Dim lights showed at intervals.

THE humming of the ship was more apparent here. It drowned the slight humming of my cloak. I crept after Anita; my hand under the cloak clutched the ray weapon.

A steward passed us. I shrank aside to avoid him.

Anita spoke to him. "Where is Miko, Ellis?"

"In the ventilator-room, Mr. Prince. There was difficulty with the air renewal."

Anita nodded, and moved on. I could have felled that steward as he passed me. Oh, if I only had, how different things might have been!

But it seemed needless. I let him go, and he turned into a nearby door which led to the galley.

Anita moved forward. If we could come upon Miko alone. Abruptly she turned, and whispered, "Gregg, if other men are with him, I'll draw him away. You watch your chance."

What little things may overthrow one's careful plans! Anita had not realized how close to her I was following. And her turning so unexpectedly caused me to collide with her sharply.

"Oh!" She exclaimed it involuntarily. Her outflung hand had unwittingly gripped my wrist, caught the electrode there. The touch burned her, and close-circuited my robe. There was a hiss. My current burned out the tiny fuses.

My invisibility was gone! I stood, a tall black-hooded figure, revealed to the gaze of anyone who might be near!

The futile plans of humans! We had planned so carefully! Our calculations, our hopes of what we could do, came clattering now in a sudden wreckage around us.

"Anita, run!"

If I were seen with her, then her own disguise would probably be discovered. That above everything would be disaster!

"Anita, get away from me! I must try it alone!"

I COULD hide somewhere, repair the cloak perhaps. Or, since now I was armed, why could I not boldly start an assault?

"Gregg, we must get you back to your cubby!" She was clinging to me in a panic.

"No! You run! Get away from me! Don't you understand? George Prince has no business here with me! They'd kill you!"

Or worse—Miko would discover it was Anita, not George Prince.

"Gregg, let's get back to the deck."

I pushed at her. Both of us in sudden confusion.

From behind me there came a shout. That accursed steward! He had returned, to investigate perhaps what George Prince was doing in this corridor. He heard our voices; his shout in the silence of the ship sounded horribly loud. The white-clothed shape of him was in the nearby doorway. He stood stricken in surprise at seeing me. And then turned to run.

I fired my paralyzing cylinder through my cloak. Got him! He fell. I shoved Anita violently.

"Run! Tell Miko to come—tell him you heard a shout! He won't suspect you!"

"But Gregg—"

"You mustn't be found out! You're our only hope, Anita! I'll hide, fix the cloak, or get back to my cubby. We'll try it again."

It decided her. She scurried down the corridor. I whirled the other way. The steward's shout might not have been heard.

Then realization flashed to me. That steward would be revived. He was one of Miko's men: for two voyages he had been a spy upon the Planetara. He would be revived and tell what he had seen and heard. Anita's disguise would be revealed.

A cold-blooded killing I do protest went against me. But it was necessary. I flung myself upon him. I beat his skull with the metal of my cylinder.

I stood up. My hood had fallen back from my head. I wiped my bloody hands on my useless cloak. I had smashed the cylinder.

"Haljan!"

ANITA'S voice! A sharp note of horror and warning. I became aware that in the corridor, forty feet down its dim length, Miko had appeared, with Anita behind him. His rifle-bullet-projector was leveled. It spat at me. But Anita had pulled at his arm.

The explosive report was sharply deafening in the confined space of the corridor. With a spurt of flame the leaden pellet struck over my head against the vaulted ceiling.

Miko was struggling with Anita. "Prince, you idiot!"

"Miko, don't! It's Haljan! Don't kill him—"

The turmoil brought members of the crew. From the shadowed oval near me they came running. I flung the useless cylinder at them. But I was trapped in the narrow passage.

I might have fought my way out. Or Miko might have shot me. But there was the danger that, in her horror, Anita would betray herself.

I backed against the wall. "Don't kill me! See, I will not fight!"

I flung up my arms. And the crew, emboldened, and courageous under Miko's gaze, leaped on me and bore me down.

The futile plans of humans! Anita and I had planned so carefully, and in a few brief minutes of action it had come only to this!

CHAPTER XVII
A Woman of Mars

"SO, Gregg Haljan, you are not as loyal as you pretend!"

Miko was livid with suppressed anger. They had stripped the cloak from me, and flung me back in my cubby. Miko was now confronting me; at the door Moa stood watching. And Anita was behind her. I sat outwardly defiant and sullen on my bunk. But I was alert and tense, fearful still of what Anita's emotion might betray her into doing.

"Not so loyal," Miko repeated. "And a fool! Do you think I am such a child you can escape me!"

He swung around. "How did he get out of here? Prince, you came in here!"

My heart was wildly thumping. But Anita retorted with a touch of spirit:

"I came to tell him what you commanded. To check Hahn's latest figures—and to be ready to take the controls when we go into the asteroid's atmosphere."

"Well, how did he get out?"

"How should I know?" she parried. Little actress! Her spirit helped to allay my fear. She held her cloak close around her in the fashion they had come to expect from the George Prince who had just buried his sister. "How should I know, Miko? I sealed his door."

"But did you?"

"Of course he did," Moa put in.

"Ask your look-outs," said Anita. "They saw me—I waved to them just as I sealed the door."

I ventured, "I have been taught to open doors." I managed a sly, lugubrious smile. "I shall not try it again, Miko."

Nothing had been said about my killing of the steward. I thanked my constellations now that he was dead. "I shall not try it again," I repeated.

A glance passed between Miko and his sister. Miko said abruptly, "You seem to realize that it is not my purpose to kill you. And you presume upon it."

"I shall not again." I eyed Moa. She was gazing at me steadily. She said, "Leave me with him, Miko...." She smiled. "Gregg Haljan, we are no more than twenty thousand miles from the asteroid now. The calculations for retarding are now in operation."

IT was what had taken Miko below, that and trouble with the ventilating system, which was soon rectified. But the retarding of the ship's velocity when nearing a destination required accurate manipulation. These brigands were fearful of their own skill. That was obvious. It gave me confidence. I was really needed. They would not harm me. Except for Miko's impulsive temper, I was in no danger from them—not now, certainly.

Moa was saying, "I think I may make you understand, Gregg. We have tremendous riches within our grasp."

"I know it," I added with sudden thought. "But there are many with whom to divide this treasure...."

Miko caught my intended implication. "By the infernal, this fellow may have felt he could seize the treasure for himself! Because he is a navigator!"

Moa said vehemently, "Do not be an idiot, Gregg! You could not do it! There will be fighting with Grantline."

My purpose was accomplished. They seemed to see me a willing outlaw like themselves. As though it were a bond between us. And they could win me.

"Leave me with him," said Moa.

Miko acquiesced. "For a few minutes only." He proffered a heat-ray cylinder, but she refused it.

"I am not afraid of him."

Miko swung on me. "Within an hour we will be nearing the atmosphere. Will you take the controls?"

"Yes."

HE set his heavy jaw. His eyes bored into me. "You're a strange fellow, Haljan. I can't make you out. I am not angry now. Do you think, when I am deadly serious, that I mean what I say?"

His calm words set a sudden shiver over me. I checked my smile.

"Yes," I said.

"Well then, I will tell you this: not for all of Prince's well-meaning interference, or Moa's liking for you, or my own need of your skill, will I tolerate more trouble from you. The next time—I will kill you. Do you believe me?"

"Yes."

"That is all I want to say. You kill my men, and my sister says I must not hurt you. I am not a child to be ruled by a woman!"

He held his huge fist before my face. "With these fingers I will twist your neck! Do you believe it?"

"Yes." I did indeed.

He swung on his heel. "If Moa wants to try and put sense into your head—I hope she does. Bring him to the lounge when you are finished, Moa. Come, Prince—Hahn will need us." He chuckled grimly. "Hahn seems to fear we will plunge into this asteroid like[72] a wild comet gone suddenly tangent!"

Anita moved aside to let him through the door. I caught a glimpse of her set white face as she followed him down the deck.

Then Moa's bulk blocked the doorway. She faced me.

"Sit where you are, Gregg." She turned and closed the door upon us. "I am not afraid of you. Should I be?"

"No," I said.

She came and sat down beside me. "If you should attempt to leave this room, the stern look-out has orders to bore you through."

"I have no intention of leaving the room," I retorted. "I do not want to commit suicide."

"I thought you did. You seem minded in such a fashion. Gregg, why are you so foolish?"

I REMAINED silent.

"Why?" she demanded.

I said carefully, "This treasure—you are many who will divide it. You have all these men on the Planetara. And in Ferrok-Shahn, others, no doubt."

I paused. Would she tell me? Could I make her talk of that other brigand ship which Miko had said was waiting on Mars? I wondered if he had been able to signal it. The distance from here to Mars was great; yet upon other voyages Snap's signals had gotten through. My heart sank at the thought. Our situation here was desperate enough. The passengers soon would be cast upon the asteroid: there would be left only Snap, Anita and myself. We might recapture the ship, but I doubted it now. My thoughts were turning to our arrival upon the Moon. We three might, perhaps, be able to thwart the attack upon Grantline, hold the brigands off until help from the Earth might come.

But with another brigand ship, fully manned and armed, coming from Mars, the condition would be immeasurably worse. Grantline had some twenty men, and his camp, I knew, would be reasonably fortified. I knew, too, that Johnny Grantline would fight to his last man.

Moa was saying, "I would like to tell you our plans, Gregg."

Her gaze was on my face. Keen eyes, but they were luminous now—an emotion in them sweeping her. But outwardly she was calm, stern-lipped.

"Well, why don't you tell me?" I said. "If I am to help you...."

"Gregg, I want you with us. Don't you understand? We are not many. My brother and I are guiding this affair. With your help, I would feel differently."

"The ship at Ferrok-Shahn—"

MY fears were realized. She said, "I think our signals reached it. Dean tried, and Coniston was checking him."

"You think the ship is coming?"

"Yes."

"Where will it join us?"

"At the Moon. We will be there in thirty hours. Your figures gave that, did they not, Gregg?"

"Yes. And the other ship—how fast is it?"

"Quite fast. In eight days—or nine, perhaps—it will reach the Moon."

She seemed willing enough to talk. There was indeed, no particular reason for reticence; I could not, she naturally felt, turn the knowledge to account.

"Manned—" I prompted.

"About forty men."

"And armed? Long range projectors?"

"You ask very avid questions, Gregg!"

"Why should I not? Don't you suppose I'm interested?" I touched her. "Moa, did it ever occur to you, if once you and Miko trusted me—which you don't—I might show more interest in joining you?"

The look on her face emboldened me. "Did you ever think of that, Moa? And some arrangement for my share of this treasure? I am not like Johnson, to be hired for a hundred pounds of gold-leaf."

"Gregg, I will see that you get your share. Riches, for you—and me."

"I was thinking, Moa, when we land at the Moon to-morrow—where is our equipment?"

The Moon, with its lack of atmosphere, needed special equipment. I had never heard Carter mention what apparatus the Planetara was carrying.

MOA laughed. "We have located air-suits and helmets—a variety of suitable apparatus, Gregg. But we were not foolish enough to leave Great-New York on this voyage without our own arrangements. My brother, and Coniston and Prince—all of us shipped crates of freight consigned to Ferrok-Shahn—and Rankin had special baggage marked 'theatrical apparatus.'"

I understood it now. These brigands had boarded the Planetara with their own Moon equipment, disguised as freight and personal baggage. Shipped in bond, to be inspected by the tax officials of Mars.

"It is on board now. We will open it when we leave the asteroid, Gregg. We are well equipped."

She bent toward me. And suddenly her long lean fingers were gripping my shoulders.

"Gregg, look at me!"

I gazed into her eyes. There was passion there; and her voice was suddenly intense.

"Gregg, I told you once a Martian girl goes after what she wants. It is you I want—"

Not for me to play like a cad upon a woman's emotions! "Moa, you flatter me."

"I love you." She held me off, gazing at me. "Gregg—"

I must have smiled. And abruptly she released me.

"So you think it amusing?"

"No. But on Earth—"

"We are not on the Earth. Nor am I of the Earth!" She was gauging me keenly. No note of pleading was in her voice; a stern authority; and the passion was swinging to anger.

"I am like my brother: I do not understand you, Gregg Haljan. Perhaps you think you are clever? It seems stupidity, the fatuousness of man!"

"Perhaps," I said.

THERE was a moment of silence. "Gregg, I said I loved you. Have you no answer?"

"No." In truth, I did not know what sort of answer it would be best to make. Whatever she must have read in my eyes, it stirred her to fury. Her fingers with the strength of a man in them, dug into my shoulders. Her gaze searched me.

"You think you love someone else? Is that it?"

That was horribly startling; but she did not mean it just that way. She amended with caustic venom: "That little Anita Prince! You thought you loved her! Was that it?"

"No!"

But I hardly deceived her. "Sacred to her memory! Her ratlike little face—soft voice like a purring, sniveling cat! Is that what you're remembering, Gregg Haljan?" she sneered.

I tried to laugh. "What nonsense!"

"Is it? Then why are you cold under my touch? Am I—a girl descended from the Martian flame-workers—impotent now to awaken a man?"

A woman scorned! In all the Universe there could be no more dangerous an enemy. An incredible venom shot from her eyes.

"That miserable mouselike creature! Well for her that my brother killed her."

It struck me cold. If Anita was unmasked, beyond all the menace of Miko's wooing, I knew that the venom of Moa's jealousy was a greater danger.

I said sharply, "Don't be simple, Moa!" I shook off her grip. "You imagine too much. You forget that I am a man of the Earth and you a girl of Mars."

"Is that reason why we should not love?"

"No. But our instincts are different. Men of the Earth are born to the chase."

I WAS smiling. With thought of Anita's danger I could find it readily in my heart to dupe this Amazon.

"Give me time, Moa. You attract me."

"You lie!"

"Do you think so?" I gripped her arm with all the power of my fingers. It must have hurt her, but she gave no sign; her gaze clung to me steadily.

"I don't know what to think, Gregg Haljan...."

I held my grip. "Think what you like. Men of Earth have been known to kill the thing they love."

"You want me to fear you?"

"Perhaps."

She smiled scornfully. "That is absurd."

I released her. I said earnestly, "I want you to realize that if you treat me fairly, I can be of great advantage to this venture. There will be fighting—I am fearless."

Her venomous expression was softening. "I think that is true, Gregg."

"And you need my navigating skill. Even now I should be in the turret."

I stood up. I half expected she would stop me, but she did not. I added, "Shall we go?"

She stood beside me. Her height brought her face level with mine.

"I think you will cause no more trouble, Gregg?"

"Of course not. I am not wholly witless."

"You have been."

"Well, that is over." I hesitated. Then I added, "A man of Earth does not yield to love when there is work to do. This treasure—"

I think that of everything I said, this last most convinced her.

She interrupted, "That I understand." Her eyes were smoldering. "When it is over—when we are rich—then I will claim you, Gregg."

SHE turned from me. "Are you ready?"

"Yes. No! I must get that sheet of Hahn's last figures."

"Are they checked?"

"Yes." I picked the sheet up from my desk. "Hahn is fairly accurate, Moa."

"A fool nevertheless. An apprehensive fool."

A comradeship seemed coming between us. It was my purpose to establish it.

"Are we going to maroon Dr. Frank with the passengers?" I asked.

"Yes."

"But he may be of use to us." I wanted Dr. Frank kept aboard. I still felt that there was a chance for us to recapture the ship.

But Moa shook her head decisively. "My brother has decided not. We will be well rid of Dr. Frank. Are you ready, Gregg?"

"Yes."

She opened the door. Her gesture reassured the look-out, who was alertly watching the stern watch-tower.

"Come, Gregg."

I stepped out, and followed her forward along the deck, which now was bright with the radiance of the nearby asteroid.

CHAPTER XVIII
Marooned on an Asteroid

A FAIR little world. I had thought so before; and I thought so now as I gazed at the asteroid hanging so close before our bow. A huge, thin crescent, with the Sun off to one side behind it. A silver crescent, tinged with red. From this near viewpoint, all of the little globe's disc was visible. The shadowed portion lay dimly red, mysteriously; the sunlit crescent—widening visibly is we approached—was gleaming silver. Inky moonlike shadows in the hollows, brilliant light upon the mountain heights. The seas lay in gray patches. The convexity of the disc was sharply defined. So small a world! Fair and beautiful, shrouded with clouded areas.

"Where is Miko?"

"In the lounge, Gregg."

"Can we stop there?"

Moa turned into the lounge archway. Strange, tense scene. I saw Anita at once. Her robed figure lurked in an inconspicuous corner; her eyes were upon me as Moa and I entered, but she did not move. The thirty-odd passengers were huddled in a group. Solemn, white-faced men, frightened women. Some of them were sobbing. One Earth-woman—a young widow—sat holding her little girl, and wailing with uncontrolled hysteria. The child knew me. As I appeared now, with my gold-laced white coat over my shoulders, the little child seemed to see in my uniform a mark of authority. She left her mother and ran to me.

"You, please—you will help us? My moms is crying."

I sent her gently back. But there came upon me then a compassion for these innocent passengers, fated to have embarked upon this ill-starred voyage. Herded here in this cabin, with brigands like pirates of old guarding them. Waiting now to be marooned on an uninhabited asteroid roaming in space. A sense of responsibility swept me. I swung upon Miko. He stood with a nonchalant grace, lounging against the wall with a cylinder dangling in his hand. He anticipated me.

"So, Haljan—she put some sense into your head? No more trouble? Then get into the turret. Moa, stay there with him. Send Hahn here. Where is that ass Coniston? We will be in the atmosphere shortly."

I said, "No more trouble from me, Miko. But these passengers—what preparation are you making for them on the asteroid?"

HE stared in surprise. Then he laughed. "I am no murderer. The crew is preparing food, all we can spare. And tools. They can build themselves shelter—they will be picked up in a few weeks."

Dr. Frank was here. I caught his gaze, but he did not speak. On the lounge couches there still lay the quarter-score bodies. Rankin, who had been killed by Blackstone in the fight; a man passenger killed; a woman and a man wounded.

Miko added, "Dr. Frank will take his medical supplies—he will care for the wounded. There are other bodies among the crew." His gesture was deprecating. "I have not buried them. We will put them ashore; easier that way."

The passengers were all eyeing me. I said:

"You have nothing to fear. I will guarantee you the best equipment we can spare. You will give them apparatus with which to signal?" I demanded of Miko.

"Yes. Get to the turret."

I turned away, with Moa after me. Again the little girl ran forward.

"Come—speak to my moms! She is crying."

It was across the cabin from Miko. Coniston had appeared from the deck; it created a slight diversion. He joined Miko.

"Wait," I said to Moa. "She is afraid of you. This is humanity."

I pushed Moa back. I followed the child. I had seen that Venza was sitting with the child's weeping mother. This was a ruse to get word with me.

I stood before the terrified woman while the little girl clung to my legs.

I said gently, "Don't be so frightened. Dr. Frank will take care of you. There is no danger—you will be safer on the asteroid than here on the ship."

I leaned down and touched her shoulder. "There is no danger."

I WAS between Venza and the open cabin. Venza whispered swiftly, "When we are landing, Gregg, I want you to make a commotion—anything—just as the women passengers go ashore."

"Why? No, of course you will have food, Mrs. Francis."

"Never mind! An instant. Just confusion. Go, Gregg—don't speak now!"

I raised the child. "You take care of mother." I kissed her.

From across the cabin Miko's sardonic voice made me turn. "Touching sentimentality, Haljan! Get to your post in the turret!"

His rasping note of annoyance brooked no delay. I set the child down. I said, "I will land us in an hour. Depend on it."

Hahn was at the controls when Moa and I reached the turret.

"You will land us safely, Haljan?" he demanded anxiously.

I pushed him away. "Miko wants you in the lounge."

"You take command here?"

"Of course, Hahn. I am no more anxious for a crash than you."

He sighed with relief. "That is true. I am no expert at atmospheric entry, Haljan—nor Coniston, nor Miko."

"Have no fear. Sit down, Moa."

I waved to the look-out in the forward watch-tower, and got his routine gesture. I rang the corridor bells, and the normal signals came promptly back.

"It's correct, Hahn. Get away with you." I called after him. "Tell Miko that things are all right here."

Hahn's small dark figure, lithe as a leopard in his tight fitting trousers and jacket with his robe now discarded, went swiftly down the spider incline and across the deck.

"Moa, where is Snap? By the infernal, if he has been injured!—"

UP on the helio-room bridge the brigand guard still sat. Then I saw that Snap was out there sitting with him. I waved from the turret window, and Snap's cheery gesture answered me. His voice carried down through the silver moonlight: "Land us safely, Gregg. These weird amateur navigators!"

Within the hour I had us dropping into the asteroid's atmosphere. The ship heated steadily. The pressure went up. It kept me busy with the instruments and the calculations. But my signals were always promptly answered from below. The brigand crew did its part efficiently.

At a hundred and fifty thousand feet I shifted the gravity plates to the landing combinations, and started the electronic engines.

"All safe, Gregg?" Moa sat at my elbow; her eyes, with what seemed a glow of admiration in them, followed my busy routine activities.

"Yes. The crew works well."

The electronic streams flowed out like a rocket tail behind us. The Planetara caught their impetus. In the rarified air, our bow lifted slightly, like a ship riding a gentle ground swell. At a hundred thousand feet we sailed gently forward, hull down to the asteroid's surface, cruising to seek a landing space.

A little sea was now beneath us. A shadowed sea, deep purple in the night down there. Occasional green-verdured islands showed, with the lines of white surf marking them. Beyond the sea, a curving coastline was visible. Rocky headlines, behind which mountain foothills rose in serrated, verdured ranks. The sunlight edged the distant mountains; and presently this rapidly turning little world brought the sunlight forward.

IT was day beneath us. We slid gently downward. Thirty thousand feet now, above a sparkling blue ocean. The coastline was just ahead: green with a lush, tropical vegetation. Giant trees, huge-leaved. Long dangling vines; air plants, with giant pods and vivid orchidlike blossoms.

I sat at the turret window, staring through my glasses. A fair little world, yet obviously uninhabited. I could fancy that all this was newly-sprung vegetation. This asteroid had whirled in from the cold of the interplanetary space far outside our Solar System. A few years ago—as time might be measured astronomically, it was no more than yesterday—this fair landscape was congealed white and bleak, with a sweep of glacial ice. But the seeds of life miraculously were here. The miracle of life! Under the warming, germinating sunlight, the verdure sprung.

"Can you find landing space, Gregg?"

Moa's question brought back my wandering fancies. I saw an upland glade, a level spread of ferns with the forest banked around it. A cliff-height nearby, frowning down at the sea.

"Yes. I can land us there." I showed her through the glasses. I rang the sirens, and we spiraled, descending further. The mountain tops were now close beneath us. Clouds were overhead, white masses with blue sky behind them. A day of brilliant sunlight. But soon, with our forward cruising, it was night. The sunlight dropped beneath the sharply convex horizon; the sea and the land went purple.

A night of brilliant stars; the Earth was a blazing blue-red point of light. The heavens visibly were revolving; in an hour or so it would be daylight again.

On the forward deck now Coniston had appeared, commanding half a dozen of the crew. They were carrying up caskets of food and the equipment which was to be given the marooned passengers. And making ready the disembarking incline, loosening the seals of the side-dome windows.

Sternward on the deck, by the lounge oval, I could see Miko standing. And occasionally the roar of his voice at the passengers sounded.

MY vagrant thought flung back into Earth's history. Like this, ancient travelers of the surface of the sea were herded by pirates to walk the plank, or put ashore, marooned upon some fair desert island of the tropic Spanish main.

Hahn came mounting our turret incline. "All is well, Gregg Haljan?"

"Get to your work," Moa told him sharply. "We land in an hour-quadrant."

He retreated, joining the bustle and confusion which now was beginning on the deck. It struck me—could I turn that confusion to account? Would it be possible, now at the last moment, to attack these brigands? Snap still sat outside the helio-room doorway. But his guard was alert, with upraised projector. And that guard, I saw, in his position high amidships, commanded all the deck.

And I saw too, as the passengers now were herded in a line from the lounge oval, that Miko had roped and bound all of the men. And a clanking chain connected them. They came like a line of convicts, marching forward, and stopped on the open deck-space near the base of the turret. Dr. Frank's grim face gazed up at me.

Miko ordered the women and children in a group beside the chained men. His words to them reached me: "You are in no danger. When we land, be careful. You will find gravity very different—this is a very small world."

I flung on the landing lights; the deck glowed with the blue radiance; the search-beams shot down beside our hull. We hung now a thousand feet above the forest glade. I cut off the electronic streams. We poised, with the gravity-plates set at normal, and only a gentle night-breeze to give us a slight side drift. This I could control with the lateral propeller rudders.

For all my busy landing routine, my mind was on other things. Venza's swift words back there in the lounge. I was to create a commotion while the passengers were landing. Why? Had she and Dr. Frank, perhaps, some last minute desperate purposes?

I DETERMINED I would do what she said. Shout, or mis-order the lights. That would be easy. But to what advantage?

I was glad it was night—I had, indeed, calculated our descent so that the landing would be in darkness. But to what purpose? These brigands were very alert. There was nothing I could think of to do which would avail us anything more than a possible swift death under Miko's anger.

"Well done, Gregg!" said Moa.

I cut off the last of the propellers. With scarcely a perceptible jar, the Planetara grounded, rose like a feather and settled to rest in the glade. The deep purple night with stars overhead was around us. I hissed out our interior air through the dome and hull-ports, and admitted the night-air of the asteroid. My calculations—of necessity mere mathematical approximations—proved fairly accurate. In temperature and pressure there was no radical change as the dome-windows slid back.

We had landed. Whatever Venza's purpose, her moment was at hand. I was tense. But I was aware also, that beside me Moa was very alert. I had thought her unarmed. She was not. She sat back from me; in her hand was a small thin knife-blade.

She murmured tensely, "You have done your part, Gregg. Well and skillfully done. Now we will sit here quietly and watch them land."

Snap's guard was standing, keenly watching. The look-outs in the forward and stern towers were also armed; I could see them both gazing keenly down at the confusion of the blue-lit deck.

The incline went over the hull-side and touched the ground.

"Enough!" Miko roared. "The men first. Hahn, move the women back! Coniston, pile those caskets to the side. Get out of the way, Prince."

ANITA was down there. I saw her at the edge of the group of women. Venza was near her.

Miko shoved her. "Get out of the way, Prince. You can help Coniston. Have the things ready to throw off."

Five of the steward-crew were at the head of the incline. Miko shouted up at me:

"Haljan, hold our shipboard gravity normal."

"Yes," I responded.

I had done so. Our magnitizers had been adjusted to the shifting calculations of our landing. They were holding now at intensities, so that upon the Planetara no change from fairly normal Earth-gravity was apparent. I rang a tentative inquiry signal; the operator in the hull-magnetizer control answered that he was at his post.

The line of men were first to descend. Dr. Frank led them. He flashed a look of farewell up at me and Snap as he went down the incline with the chained men passengers after him.

Motley procession! Twenty odd, dishevelled, half-clothed men of three worlds. The changing, lightening gravity on the incline caught them. Dr. Frank bounded up to the rail under the impetus of his step: caught and held himself, drew himself back. The line swayed. In the dim, blue-lit glare it seemed unreal, crazy. A grotesque dream of men descending a plank.

They reached the forest glade. Stood swaying, afraid at first to move. The purple night crowded them; they stood gazing at this strange world, their new prison.

"Now the women."

Miko was shoving the women to the head of the incline. I could feel Moa's steady gaze upon me. Her knife-blade gleamed in the turret light.

She murmured again, "In a few minutes you can ring us away, Gregg."

I FELT like an actor awaiting his cue in the wings of some turgid drama the plot of which he did not know. Venza was near the head of the incline. Some of the women and children were on it. A woman screamed. Her child had slipped from her hand, bounded up over the rail, and fallen. Hardly fallen—floated down to the ground, with flailing arms and legs, landing in the dark ferns, unharmed. Its terrified wail came up.

There was a confusion on the incline. Venza, still on the deck, seemed to send a look of appeal to the turret. My cue?

I slid my hand to the light switchboard. It was near my knees. I pulled a switch. The blue-lit deck beneath the turret went dark.

I recall an instant of horrible, tense silence, and in the gloom beside me I was aware of Moa moving. I felt a thrill of instinctive fear—would she plunge that knife into me?

The silence of the darkened deck was broken with a confusion of sounds. A babble of voices; a woman passenger's scream; shuffling of feet; and above it all, Miko's roar:

"Stand quiet! Everyone! No movement!"

On the descending incline there was chaos. The disembarking women were clinging to the gang-rail; some of them had evidently surged over it and fallen. Down on the ground in the purple-shadowed starlight I could vaguely see the chained line of men. They too were in confusion, trying to shove themselves toward the fallen women.

Miko roared:

"Light those tubes! Gregg Haljan! By the Almighty, Moa, are you up there? What is wrong? The light-tubes—"

Dark drama of unknown plot! I wonder if I should try and leave the turret. Where was Anita? She had been down there on the deck when I flung out the lights.

I think twenty seconds would have covered it all. I had not moved. I thought, "Is Snap concerned with this?"

Moa's knife could have stabbed me. I felt her lunge against me; and suddenly I was gripping her, twisting her wrist. But she flung the knife away. Her strength was almost the equal of my own. Her hand went for my throat, and with the other hand she was fumbling.

THE deck abruptly sprang into light again. Moa had found the switch and threw it back.

"Gregg!"

She fought me as I tried to reach the switch. I saw down on the deck Miko gazing up at us. Moa panted, "Gregg—stop! If he—sees you doing this, he'll kill you—"

The scene down there was almost unchanged. I had answered my cue. To what purpose? I saw Anita near Miko. The last of the women were on the plank.

I had stopped struggling with Moa. She sat back, panting; and then she called: "Sorry, Miko. It will not happen again."

Miko was in a towering rage. But he was too busy to bother with me; his anger swung on those nearest him. He shoved the last of the women violently at the incline. She bounded over. Her body, with the gravity-pull of only a few Earth-pounds, sailed in an arc and dropped to the sward near the swaying line of men.

Miko swung back. "Get out of my way!" A sweep of his huge arm knocked Anita sidewise. "Prince, damn you, help me with those boxes!"

The frightened stewards were lifting the boxes, square metal storage-chests each as long as a man, packed with food, tools, and equipment.

"Here, get out of my way, all of you!"

My breath came again; Anita nimbly retreated before Miko's angry rush. He dashed at the stewards. Three of them held a box. He took it from them; raised it at the top of the incline. Poised it over his head an instant, with his massive arms like gray pillars beneath it. And flung it. The box catapulted, dropped; and then, passing the Planetara's gravity area, it sailed in a long flat arc over the forest glade and crashed into the purple underbrush.

"Give me another!"

THE stewards pushed another at him. Like an angry Titan, he flung it. And another. One by one the chests sailed out and crashed.

"There is your food—go pick it up! Haljan, make ready to ring us away!"

On the deck lay the dead body of Rance Rankin, which the stewards had carried out. Miko seized it, flung it.

"There! Go to your last resting place!"

And the other bodies. Balch Blackstone, Captain Carter, Johnson—Miko[80] flung them. And the course masters and those of our crew who had been killed; the stewards appeared with them; Miko unceremoniously cast them off.

The passengers were all on the ground now. It was dim down there. I tried to distinguish Venza, but could not. I could see Dr. Frank's figure at the end of the chained line of men. The passengers were gazing in horror at the bodies hurtling over them.

"Ready, Haljan?"

Moa prompted me. "Tell him yes!"

I called, "Yes!" Had Venza failed in her unknown purpose? It seemed so. On the helio-room bridge Snap and his guard stood like silent statues in the blue-lit gloom.

The disembarkation was over.

"Close the ports," Miko commanded.

The incline came folding up with a clatter. The port and dome-windows slid closed. Moa hissed against my ear:

"If you want life, Gregg Haljan, you will start your duties!"

Venza had failed. Whatever it was, it had come to nothing. Down in the purple forest, disconnected now from the ship, the last of our friends stood marooned. I could distinguish them through the blur of the closed dome—only a swaying, huddled group was visible. But my fancy pictured this last sight of them—Dr. Frank, Venza, Shac and Dud Ardley.

They were gone. There were left only Snap, Anita, and myself.

I WAS mechanically ringing us away. I heard my sirens sounding down below, with the answering clangs here in the turret. The Planetara's respiratory controls started; the pressure equalizers began operating, and the gravity plates shifted into lifting combinations.

The ship was hissing and quivering with it, combined with the grating of the last of the dome ports. And Miko's command:

"Lift, Haljan."

Hahn had been mingled with the confusion of the deck, though I had hardly noticed him; Coniston had remained below, with the crew answering my signals. Hahn stood now with Miko, gazing down through a deck window. Anita was alone at another.

"Lift, Haljan."

I lifted us gently, bow first, with a repulsion of the bow plates. And started the central electronic engine. Its thrust from our stern moved us diagonally over the purple forest trees.

The glade slid downward and away. I caught a last vague glimpse of the huddled group of marooned passengers, staring up at us. Left to their fate, alone on this deserted little world.

With the three engines going we slid smoothly upward. The forest dropped, a purple spread of tree-tops, edged with starlight and Earth-light. The sharply curving horizon seemed following us up. I swung on all the power. We mounted at a forty degree angle, slowly circling, with a bank of clouds over us to the side and the shining little sea beneath.

"Very good, Gregg." In the turret light Moa's eyes blazed at me. "I do not know what you meant by darkening the deck-lights." Her fingers dug at my shoulders. "I will tell my brother it was an error."

I said, "An error—yes."

"An error? I don't know what it was. But you have me to deal with now. You understand? I will tell my brother so. You said, 'On Earth a man may kill the thing he loves.' A woman of Mars may do that! Beware of me, Gregg Haljan."

Her passion-filled eyes bored into me. Love? Hate? The venom of a woman scorned—a mingling of turgid emotions....

I TWISTED away from her grip and ignored her; she sat back, silently watching my busy activities; the calculations of the shifting conditions of gravity, pressures, temperatures; a checking of the score or more of instruments on the board before me.

Mechanical routine. My mind went to Venza, back there on the asteroid. The wandering little world was already shrinking to a convex surface beneath us. Venza, with her last unknown play, gone to failure. Had I failed my cue? Whatever my part, it seemed now that I must have horribly mis-acted it.

The crescent Earth was presently swinging over our bow. We rocketed out of the asteroid's shadow. The glowing, flaming Sun appeared, making a crescent of the Earth. With the glass I could see our tiny Moon, visually seeming to hug the limb of its parent Earth.

We were away upon our course for the Moon. My mind flung ahead. Grantline with his treasure, unsuspecting this brigand ship. And suddenly, beyond all thought of Grantline and his treasure, there came to me a fear for Anita. In God's truth I had been, so far, a very stumbling inept champion—doomed to failure with everything I tried. It swept me, so that I cursed my own incapacity. Why had I not contrived to have Anita desert at the asteroid? Would it not have been far better for her there? Taking her chance for rescue with Dr. Frank, Venza and the others?

But no! I had, like an inept fool, never thought of that! Had left her here on board at the mercy of these outlaws.

And I swore now that, beyond everything, I would protect her.

Futile oath! If I could have seen ahead a few hours! But I sensed the catastrophe. There was a shudder within me as I sat in that turret, docilely guiding us out through the asteroid's atmosphere, heading us upon our course for the Moon.

CHAPTER XIX
In the Zed-light Glow

"TRY again. By the infernal, Snap Dean, if you do anything to balk us!"

Miko scanned the apparatus with keen eyes. How much technical knowledge of signaling instruments did this brigand leader have? I was tense and cold with apprehension as I sat in a corner of the helio-room, watching Snap. Could Miko be fooled? Snap, I knew, was trying to fool him.

The Moon spread close beneath us. My log-chart, computed up to thirty minutes past, showed us barely some thirty thousand miles over the Moon's surface. The globe lay in quadrature beneath our bow quarter—a huge quadrant spreading across the black starry vault of the lower heavens. A silver quadrant. The sunset caught the Lunar mountains, flung slanting shadows over the empty Lunar plains. All the disc was plainly visible. The mellow Earth-light glowed serene and pale to illumine the Lunar night.

The Planetara was bathed in silver. A brilliant silver glare swept the forward deck, clean white and splashed with black shadows. We had partly circled the Moon, so as now to approach it from the Earthward side. I had worked with extreme concentration through the last few hours, plotting the trajectory of our curving sweep, setting the gravity plates with constantly shifting combinations. And with it a necessity for the steady retarding of our velocity.

MIKO for a time was at my elbow in the turret. I had not seen Coniston and Hahn of recent hours. I had slept, awakened refreshed, and had a meal. Coniston and Hahn remained below, one or the other of them always with the crew to execute my sirened orders. Then Coniston came to take my place in the turret, and I went with Miko to the helio-room.

"You are skilful, Haljan." A measure of grim approval was in Miko's voice. "You evidently have no wish to try and fool me in this navigation."

I had not, indeed. It is delicate work at best, coping with the intricacies of celestial mechanics upon a semicircular trajectory with retarding velocity, and with a make-shift crew we could easily have come upon real difficulty.

We hung at last, hull-down, facing the Earthward hemisphere of the Lunar disc. The giant ball of the Earth lay behind and above us—the Sun over our stern quarter. With forward velocity almost checked, we poised, and Snap began his signals to the unsuspecting Grantline.

My work momentarily was over. I sat watching the helio-room. Moa was here, close beside me; I felt always her watchful gaze, so that even the play of my expression needed reining.

Miko worked with Snap. Anita too was here. To Miko and Moa it was the somber, taciturn George Prince, shrouded always in his black mourning cloak, disinclined to talk; sitting alone, brooding and cowardly sullen.

Miko repeated, "By the infernal, if you try to fool me, Snap Dean!"

The small metal room, with its grid floor and low-arched ceiling, glared with moonlight through its windows. The moving figures of Snap and Miko were aped by the grotesque, misshapen shadows of them on the walls. Miko gigantic—a great, menacing ogre. Snap small and alert—a trim, pale figure in his tight-fitting white trousers, broad-flowing belt, and white shirt open at the throat. His face was pale and drawn from lack of sleep and the torture to which Miko had subjected him. But he grinned at the brigand's words, and pushed his straggling hair closer under the red eyeshade.

"I'm doing my best, Miko—you can believe it."

THE room over long periods was deadly silent, with Miko and Snap bending watchfully at the crowded banks of instruments. A silence in which my own pounding heart seemed to echo. I did not dare look at Anita, nor she at me. Snap was trying to signal Earth, not the Moon! His main helios were set in the reverse. The infra-red waves, flung from the bow window, were of a frequency which Snap and I believed that Grantline could not pick up. And over against the wall, close beside me and seemingly ignored by Snap, there was a tiny ultra-violet sender. Its faint hum and the quivering of its mirrors had so far passed unnoticed.

Would some Earth-station pick it up? I prayed so. There was a thumb nail mirror here which could bring an answer. I prayed that it might swing.

Would some Earth telescope be able to see us? I doubted it. The pinpoint of the Planetara's infinitesimal bulk would be beyond them.

Long silences, broken only by the faint hiss and murmur of Snap's instruments.

"Shall I try the 'graphs, Miko?"

"Yes."

I helped him with the spectroheliograph. At every level the plates showed us nothing save the scarred and pitted Moon-surface. We worked for an hour. There was nothing. Bleak cold night on the Moon here beneath us. A touch of fading sunlight upon the Apennines. Up near the South Pole, Tycho with its radiating open rills stood like a grim dark maw.

Miko bent over a plate. "Something here? Is there?"

An abnormality upon the frowning ragged cliffs of Tycho? We thought so. But then it seemed not.

ANOTHER hour. No signal came from Earth. If Snap's calls were getting through we had no evidence of it. Abruptly Miko strode at me from across the room. I went cold and tense; Moa shifted, alert to my every movement. But Miko was not interested in me. A sweep of his clenched fist knocked the ultra-violet sender and its coils and mirrors in a tinkling crash to the grid at my feet.

"We don't need that, whatever it is!"

He rubbed his knuckles where the violet waves had tinged them, and turned grimly back to Snap.

"Where are your Gamma ray mirrors? If the treasure is exposed—"

This Martian's knowledge was far greater than we believed. He grinned sardonically at Anita. "If our treasure is on this hemisphere, Prince, we should pick up Gamma rays? Don't you think so? Or is Grantline so cautious it will all be protected?"

Anita spoke in a careful, throaty drawl. "The Gamma rays came plain enough when we passed here on the way out."

"You should know," grinned Miko. "An expert eavesdropper, Prince—I will say that for you. Come Dean, try something else. By God, if Grantline does not signal us, I will be likely to blame you—my patience is shortening. Shall we go closer, Haljan?"

"I don't think it would help," I said.

He nodded. "Perhaps not. Are we checked?"

"Yes." We were poised, very nearly motionless. "If you wish an advance, I can ring it. But we need a surface destination now."

"True, Haljan." He stood thinking. "Would a zed-ray penetrate those crater-cliffs? Tycho, for instance, at this angle?"²

2: An allusion to the use of the zed-ray light for making spectro-photographs of what might be behind obscuring rock masses, similar to the old-style X-ray.

"It might," Snap agreed. "You think he may be on the Northern inner side of Tycho?"

"He may be anywhere," said Miko shortly.

"If you think that," Snap persisted, "suppose we swing the Planetara over the South Pole. Tycho, viewed from there—"

"And take another quarter-day of time?" Miko sneered. "Flash on your zed-ray; help him hook it up, Haljan."

I MOVED to the lens-box of the spectroheliograph. It seemed that Snap was very strangely reluctant: Was it because he knew that the Grantline camp lay concealed on the north inner wall of Tycho's giant ring? I thought so. But Snap flashed a queer look at Anita. She did not see it, but I did. And I could not understand it.

My accursed, witless incapacity! If only I had taken warning!

"Here," commanded Miko. "A score of 'graphs with the zed-ray. I tell you I will comb this surface if we have to stay here until our ship comes from Ferrok-Shahn to join us!"

The Martian brigands were coming. Miko's signals had been answered. In ten days the other brigand ship, adequately manned and armed, would be here.

Snap helped me connect the zed-ray. He did not dare even to whisper to me, with Moa hovering always so close. And for all Miko's sardonic smiling, we knew that he would tolerate nothing from us now. He was fully armed, and so was Moa.

I recall that Snap several times tried to touch me significantly. Oh, if only I had taken warning!

We finished our connecting. The dull gray point of zed-ray gleamed through the prisms, to mingle with the moonlight entering the main lens. I stood with the shutter trip.

"The same interval, Snap?"

"Yes."

Beside me, I was aware of a faint reflection of the zed-light—a gray Cathedral shaft crossing the helio-room and falling upon the opposite wall. An unreality there, as the zed-light faintly strove to penetrate the metal room-side.

I said, "Shall I make the exposure?"

SNAP nodded. But that 'graph was never made. An exclamation from Moa made us all turn. The Gamma mirrors were quivering! Grantline had picked our signals! With what undoubtedly was an intensified receiving equipment which Snap had not thought Grantline able to use, he had caught our faint zed-rays, which Snap was sending only to deceive Miko. And Grantline had recognized the Planetara, and had released his occulting screens surrounding the radium ore. The Gamma rays were here, unmistakable!

And upon their heels came Grantline's message. Not in the secret system he had arranged with Snap, but unsuspectingly in open code. I could read the swinging mirror, and so could Miko.

And Miko decoded it triumphantly aloud:

"Surprised but pleased your return. Approach Mid-Northern hemisphere, region of Archimedes, forty thousand toises³ off nearest Apennine range."

3: About fifty miles.

The message broke off. But even its importance was overshadowed. Miko stood in the center of the helio-room, triumphantly reading the light-indicator. Its beam swung on the scale, which chanced to be almost directly over Anita's head. I saw Miko's expression change. A look of surprise, amazement came to him.

"Why—"

He gasped. He stood staring. Almost stupidly staring for an instant. And as I regarded him with fascinated horror, there came upon his heavy gray face a look of dawning comprehension. And I heard Snap's startled intake of breath. He moved to the spectroheliograph, where the zed-ray connections were still humming.

But with a leap Miko flung him away. "Off with you! Moa, watch him! Haljan, don't move!"

AGAIN Miko stood staring. Oh dear God, I saw now that he was staring at Anita!

"Why George Prince! How strange you look!"

Anita did not move. She was stricken with horror: she shrank back against the wall, huddled in her cloak. Miko's sardonic voice came again:

"How strange you look. Prince!" He took a step forward. He was grim and calm. Horribly calm. Deliberate. Gloating—like a great gray monster in human form toying with a fascinated, imprisoned bird.

"Move just a little Prince. Let the zed-ray light fall more fully."

Anita's head was bare. That pale, Hamletlike face. Dear God, the zed-light reflection lay gray and penetrating upon it!

Miko took another step. Peering. Grinning. "How amazing, George Prince! Why, I can hardly believe it!"

Moa was armed with an electronic cylinder. For all her amazement—what turgid emotions sweeping her I can only guess—she never took her eyes from Snap and me.

"Back! Don't move, either of you!" She hissed it at us.

Then Miko leaped at Anita like giant gray leopard pouncing.

"Away with that cloak, Prince!"

I STOOD cold and numbed. And realization came at last. The faint zed-light glow had fallen by chance upon Anita's face. Penetrated the flesh; exposed, faintly glowing, the bone-line of her jaw. Unmasked the waxen art of Glutz.

And Miko had seen it.

"Why George, how surprising! Away with that cloak!"

He seized her wrist, drew her forward, beyond the shaft of zed-light, into the brilliant light of the Moon. And ripped her cloak from her. The gentle curves of her woman's figure were so unmistakable!

And as Miko gazed at them, all his calm triumph swept away.

"Why, Anita!"

I heard Moa mutter: "So that is it?" A venomous flashing look—a shaft from me to Anita and back again. "So that is it?"

"Why, Anita!"

Miko's great arms gathered her up as though she were a child. "So I have you back; from the dead delivered back to me!"

"Gregg!" Snap's warning, and his grip over my shoulders brought me a measure of sanity. I had tensed to spring. I stood quivering, and Moa thrust her weapon against my face. The helio mirrors were swaying again with another message from Grantline. But it came ignored by us all.

In the glare of moonlight by the forward window, Miko held Anita, his great hands pawing her with triumphant possessive caresses.

"So, little Anita, you are given back to me."

Against her futile struggles he held her.

Dear God, if only I had had the wit to have prevented this!

CHAPTER XX
The Grantline Camp

IN the mid-northern hemisphere upon the Earthward side of the Moon, the giant crater of Archimedes stood brooding in silent majesty. Grim, lofty walls, broken, pitted and scarred, rising precipitous to the upper circular rim. Night had just fallen. The sunlight clung to the crater-heights; it tinged with flame the jagged peaks of the Apennine Mountains which rose in tiers at the horizon; and it flung great inky shadows over the intervening lowlands.

Northward, the Mare Imbrium stretched mysterious and purple, its million rills and ridges and crater holes flattened by distance and the gathering darkness into a seeming level surface. The night slowly deepened. The dead-black vault of the sky blazed with its brilliant starry gems. The gibbous Earth hung high above the horizon, motionless, save for the invisible pendulum sway over the tiny arc, of its libration: widening to quadrature, casting upon the bleak naked Lunar landscape its mellow Earth-glow.

Slow, measured process, this coming of the Lunar night! For an Earth-day the sunset slowly faded on the Apennines; the poised Earth widened a little further—an Earth-day of time, with the Earth-disc visibly rotating, the faint tracery of its oceans and continents passing in slow, majestic review.

Another Earth-day interval. Then another. And another. Full night now enveloped Archimedes. Splotches of Earth-light and starlight sheen slowly shifted as the night advanced.

Between the great crater and the nearby mountains, the broken, pseudo-level lowlands lay wan in the Earth-light. A few hundred miles, as distance would be measured upon Earth. A million million rills were here. Valleys and ridges, ravines, sharp-walled canyons, cliffs and crags—tiny craters like pock-marks.

Naked, gray porous rock everywhere. This denuded landscape! Cracked and scarred and tumbled, as though some inexorable Titan torch had seared and crumbled and broken it, left it now congealed like a wind-lashed sea abruptly frozen into immobility.

MOONLIGHT upon Earth so gently shines to make romantic a lover's smile! But the reality of the Lunar night is cold beyond human rationality. Cold and darkly silent. Grim desolation. Awesome. Majestic. A frowning majesty that even to the most intrepid human beholder is inconceivably forbidding.

And there were humans here now. On this tumbled plain, between Archimedes and the mountains, one small crater amid the million of its fellows was distinguished this night by the presence of humans. The Grantline camp! It huddled in the deepest purple shadows on the side of a bowl-like pit, a crudely circular orifice with a scant two miles across its rippling rim. There was faint light here to mark the presence of the living intruders. The blue-glow radiance of Morrell tube-lights under a spread of glassite.

The Grantline camp stood mid-way up one of the inner cliff-walls of the little crater. The broken, rock-strewn floor, two miles wide, lay five hundred feet below the camp. Behind it, the jagged precipitous cliff rose another five hundred to the heights of the upper rim. A broad level shelf hung midway up the cliff, and upon it Grantline had built his little group of glassite dome shelters. Viewed from above there was the darkly purple crater floor, the upflung circular rim where the Earth-light tinged the spires and crags with yellow sheen; and on the shelf, like a huddled group of birds nests, Grantline's domes clung and gazed down upon the inner valley.

Intricate task, the building of these glassite shelters! There were three. The main one stood close at the brink of the ledge. A quadrangle of glassite walls, a hundred feet in length by half as wide, and a scant ten feet high to its flat-arched dome roof. Built for this purpose in Great-New York, Grantline had brought his aluminite girders and braces and the glassite panels in sections.

THE air here on the Moon surface was negligible—a scant one five-thousandth of the atmospheric pressure at the sea-level on Earth. But within the glassite shelter, a normal Earth-pressure must be maintained. Rigidly braced double walls to withstand the explosive tendency, with no external pressure to counteract it. A tremendous necessity for mechanical equipment had burdened Grantline's small ship to its capacity. The chemistry of manufactured air, the pressure equalizers, renewers, respirators, the lighting and temperature-maintenance systems—all the mechanics of a space-flyer were here.

And within the glassite double walls, there was necessity for a constant circulation of the Erentz temperature insulating system.⁴

4: An intricate system of insulation against extremes of temperature, developed by the Erentz Kinetic Energy Corporation in the twenty-first century. Within the hollow double shell of a shelter-wall, or an explorer's helmet-suit, or a space-flyer's hull, an oscillating semi-vacuum current was maintained—an extremely rarified air, magnetically charged, and maintained in rapid oscillating motion. Across this field the outer cold, or heat, as the case might be, could penetrate only with slow radiation. This Erentz system gave the most perfect temperature insulation known in its day. Without it, interplanetary flight would have been impossible.

And it served a double purpose. Developed at first for temperature insulation only, the Erentz system surprisingly brought to light one of the most important discoveries made in the realm of physics of the century. It was found that any flashing, oscillating current, whether electronic, or the semi-vacuum of rarified air—or even a thin sheet of whirling fluid—gave also a pressure-insulation. The kinetic energy of the rapid movement was found to absorb within itself the latent energy of the unequal pressure.

(The intricate postulates and mathematical formulae necessary to demonstrate the operation of the physical laws involved would be out of place here.)

The Planetara was so equipped, against the explosive tendency of its inner air-pressures when flying in the near-vacuum of space. In the case of Grantline's glassite shelters, the latent energy of his room interior air pressure went largely into a kinetic energy which in practical effect resulted only in the slight acceleration of the vacuum current, and thus never reached the outer wall. The Erentz engineers claimed for their system a pressure absorption of 97.4%, leaving, in Grantline's case, only 2.6% of room pressure to be held by the building's aluminite bracers.

It may be interesting to note in this connection that without the Erentz system as a basis, the great sub-sea developments on Earth and Mars of the twenty-first century would also have been impossible. Equipped with a fluid circulation device of the Erentz principle within its double hull, the first submarine was able to penetrate the great ocean deeps, withstanding the tremendous ocean pressures at depths of four thousand fathoms.

There was this main Grantline building, stretching low and rectangular along the front edge of the ledge. Within it were living rooms, messroom and kitchen. Fifty feet behind it, connected by a narrow passage of glassite, was a similar, though smaller structure. The mechanical control rooms, with their humming, vibrating mechanisms were here. And an instrument room with signaling apparatus, senders, receivers, mirror-grids and audiphones of several varieties; and an electro-telescope, small but modern, with dome overhead like a little Earth observatory.

From this instrument building, beside the connecting pedestrian passage, wire cables for light, and air-tubes and strings and bundles of instrument wires ran to the main structure—gray snakes upon the porous, gray Lunar rock.

The third building seemed a lean-to banked against the cliff-wall, a slanting shed-wall of glassite fifty feet high and two hundred in length. Under it, for months Grantline's borers had dug into the cliff. Braced tunnels were here, penetrating back and downward into this vein of radio-active rock.

THE work was over now. The borers had been dismantled and packed away. At one end of the cliff the mining equipment lay piled in a litter. There was a heap of discarded ore where Grantline had carted and dumped it after his first crude refining process had yielded it as waste. The ore-slag lay like gray powder-flakes strewn down the cliff. Tracks and ore-carts along the ledge stood discarded, mute evidence of the weeks and months of work these helmeted miners had undergone, struggling upon this airless, frowning world.

But now all that was finished. The radio-active ore was sufficiently concentrated. It lay—this treasure—in a seventy-foot pile behind the glassite lean-to, with a cage of wires over it and an insulation barrage guarding its Gamma rays from escaping to mark its presence.

The ore-shelter was dark; the other two buildings were lighted. And there were small lights mounted at intervals about the camp and along the edge of the ledge. A spider ladder, with tiny platforms some twenty feet one above the other, hung precariously to the cliff-face. It descended the five hundred feet to the crater floor; and, behind the camp, it mounted the jagged cliff-face to the upper rim-height, where a small observatory platform was placed.

SUCH was the outer aspect of the Grantline Treasure Camp near the beginning of this Lunar night, when, unbeknown to Grantline and his score of men, the Planetara with its brigands was approaching. The night was perhaps a sixth advanced. Full night. No breath of cloud to mar the brilliant starry heavens. The quadrant Earth hung poised like a giant mellow moon over Grantline's crater. A bright Earth, yet no air was here on this Lunar surface to spread its light. Only a glow, mingling with the spots of blue tube-light on the poles along the cliff, and the radiance from the lighted buildings.

The crater floor was dimly purple. Beyond the opposite upper rim, from the camp-height, the towering top of distant Archimedes was visible.

No evidence of movement showed about the silent camp. Then a pressure door in an end of the main building opened its tiny series of locks. A bent figure came out. The lock closed. The figure straightened and gazed about the camp. Grotesque, bloated semblance of a man! Helmeted, with rounded dome-hood suggestion of an ancient sea diver, yet goggled and trunked like a gas-masked fighter of the twentieth century war.

He stooped presently and disconnected metal weights which were upon his shoes.⁵

5: Within the Grantline buildings it was found more convenient to use a gravity normal to Earth. This was maintained by the wearing of metal-weighted shoes and metal-loaded belt. The Moon-gravity is normally approximately one-sixth the gravity of Earth.

Then he stood erect again, and with giant strides bounded along the cliff. Fantastic figure in the blue-lit gloom! A child's dream of crags and rocks and strange lights with a single monstrous figure in seven-league boots.

He went the length of the ledge with his twenty-foot strides, inspected the lights, and made adjustments. Came back, and climbed with agile, bounding leaps up the spider ladder to the dome on the crater top. A light flashed on up there. Then it was extinguished.

The goggled, bloated figure came leaping down after a moment. Grantline's exterior watchman making his rounds. He came back to the main building. Fastened the weights on his shoes. Signaled within.

The lock opened. The figure went inside.

It was early evening, after the dinner hour and before the time of sleep, according to the camp routine Grantline was maintaining. Nine P. M. of Earth Eastern-American time, recorded now upon his Earth chronometer. In the living room of the main building Johnny Grantline sat with a dozen of his men dispersed about the room, whiling away as best they could the lonesome hours.

"ALL as usual. This cursed Moon! When I get home—if ever I do get home—"

"Say your say, Wilks. But you'll spend your share of the gold-leaf and thank your constellations that you had your chance!"

"Let him alone! Come on, Wilks, take a hand here. This game is no good with three."

The man who had been outside flung his hissing helmet recklessly to the floor and unsealed his suit. "Here, get me out of this. No, I won't play. I can't play your cursed game with nothing at stake!"

"Commissioner's orders."

A laugh went up at the sharp look Johnny Grantline flung from where he sat reading in a corner of the room.

"Commander's orders. No gambling gold-leafers tolerated here."

"Play the game, Wilks." Grantline said quietly. "We all know it's infernal doing nothing."

"He's been struck by Earth-light," another man laughed. "Commander, I told you not to let that guy Wilks out at night."

A ROUGH but good-natured lot of men. Jolly and raucous by nature in their leisure hours. But there was too much leisure here now. Their mirth had a hollow sound. In older times, explorers of the frozen polar zones had to cope with inactivity, loneliness and despair. But at least they were on their native world. The grimness of the Moon was eating into the courage of Grantline's men. An unreality here. A weirdness. These fantastic crags. The deadly silence. The nights, almost two weeks of Earth-time in length, congealed by the deadly frigidity of Space. The days of black sky, blaring stars and flaming Sun, with no atmosphere to diffuse the daylight. Days of weird blending sheen of illumination with most of the Sun's heat radiating so swiftly from the naked Lunar surface that the outer temperature still was cold. And day and night, always the familiar beloved Earth-disc hanging poised up near the zenith. From thinnest crescent to full Earth, and then steadily back again to crescent.

All so abnormal, irrational, disturbing to human senses. With the mining work over, an irritability grew upon Grantline's men. And perhaps since the human mind is so wonderful, elusive a thing, there lay upon these men an indefinable sense of impending disaster. Johnny Grantline felt it. He thought about it now as he sat in the room corner watching Wilks being forced into the plaget-game, and he found it strong within him. Unreasonable, ominous depression! Barring the accident which had disabled his little space-ship when they reached this small crater hole, his expedition had gone well. His instruments, and the information he had from the former explorers, had picked up the ore-vein with a scant month of search.

THE vein had now been exhausted; but the treasure was here. Nothing was left but to wait for the Planetara. The men were talking of that now.

"She ought to be well mid-way from here to Ferrok-Shahn by now. When do you figure she'll be back here, and signal us?"

"Twenty days. Give her another five now to Mars, and five in port. That's ten. We'll pick her signals in three weeks, mark me."

"Three weeks! Just give me three weeks of reasonable sunrise and sunset! This cursed Moon! You mean, Williams, next daylight."

"Hah! He's inventing a Lunar language. You'll be a Moon-man yet, if you live here long enough."

Olaf Swenson, the big blond fellow from the Scandia fiords, came and flung himself down by Grantline.

"Ay tank they bane without not enough to do, Commander. If the ore yust would not give out—"

"Three weeks—it isn't very long, Ollie."

"No. Maybe not."

From across the room somebody was saying, "If the Comet hadn't smashed on us, damn me but I'd ask the Commander to let some of us take her back. The discarded equipment could go."

"Shut up, Billy. She is smashed."

The little Comet, cruising in search of the ore, had come to grief just as the ore was found. It lay now on the crater floor with its nose bashed into an upflung spire of rock. Wrecked beyond repair. Save for the pre-arrangement with the Planetara, the Grantline party would have been helpless here on the Moon. Knowledge of that—although no one ever suspected but that the Planetara would come safely—served to add to the men's depression. They were cut off, virtually helpless on a strange world. Their signalling devices were inadequate even to reach Earth. Grantline's power batteries were running low.⁶ He could not attempt wide-flung signals without jeopardizing the power necessary for the routine of his camp in the event of the Planetara being delayed. Nor was his electro-telescope adequate to pick small objects at any great distance.⁷

6: The Gravely storage tanks—the power used by the Grantline expedition—were heavy and bulky affairs. Economy of space on the Comet allowed but few of them.

7: Electro-telescopes of most modern use and power were too large and used too much power to be available to Grantline.

All of Grantline's effort, in truth, had gone into equipment for the finding and gathering of the treasure. The safety of the expedition had to that extent been neglected.

Swenson was mentioning that now.

"You all agreed to it," Johnny said shortly. "Every man here voted that, above everything, what we wanted was to get the radium."

A DYNAMIC little fellow, this Johnny Grantline. Short of temper sometimes, but always just, and a perfect leader of men. In stature he was almost as small as Snap. But he was thick-set, with a smooth shaven, keen-eyed, square-jawed face, and a shock of brown tousled hair. A man of thirty-five, though the decision of his manner, the quiet dominance of his voice, mode him seem older. He stood up now, surveying the blue-lit glassite room with its low ceiling close overhead. He was bowlegged; in movement he seemed to roll with a stiff-legged gait like some sea captain of former days on the deck of his swaying ship. Queer-looking figure! Heavy flannel shirt and trousers, boots heavily weighted, and bulky metal-loaded belt strapped about his waist.

He grinned at Swenson. "When we divide this treasure, everyone will be happy, Ollie."

The treasure was estimated by Grantline to be the equivalent of ninety millions in gold-leaf. A hundred and ten millions in the gross as it now stood, with twenty millions to be deducted by the Federated Refiners for reducing it to the standard purity of commercial radium. Ninety millions, with only a million and a half to come off for expedition expenses, and the Planetara Company's share another million. A nice little stake.

Grantline strode across the room with his rolling gait.

"Cheer up, boys. Who's winning there? I say, you fellows—"

An audiphone buzzer interrupted him, a call from the duty man in the instrument room of the nearby building.

Grantline clicked the receiver. The room fell into silence. Any call was unusual—nothing ever happened here in the camp.

The duty man's voice sounded over the room.

"Signals coming! Not clear. Will you come over, Commander?"

Signals!

IT was never Grantline's way to enforce needless discipline. He offered no objection when every man in the camp rushed through the connecting passages. They crowded the instrument room where the tense duty man sat bending over his helio receivers. The mirrors were swaying.

The duty man looked up and met Grantline's gaze.

"I ran it up to the highest intensity. Commander. We ought to get it—not let it pass."

"Low scale, Peter?"

"Yes. Weakest infra-red. I'm bringing it up, even though it uses too much of our power." The duty man was apologetic.

"Get it," said Grantline shortly.

"I had a swing a minute ago. I think it's the Planetara."

"Planetara!" The crowding group of men chorused it. How could it be the Planetara?

But it was. The call presently came in clear. Unmistakably the Planetara, turned back now from her course to Ferrok-Shahn.

"How far away, Peter?"

The duty man consulted the needles of his dial scale. "Close! Very weak infra-red. But close. Around thirty thousand miles, maybe. It's Snap Dean calling."

The Planetara here within thirty thousand miles! Excitement and pleasure swept the room. The Planetara's coming had for so long been awaited so eagerly!

The excitement communicated to Grantline. It was unlike him to be incautious; yet now with no thought save that some unforeseen and pleasing circumstance had brought the Planetara ahead of time; incautious Grantline certainly was.

"Raise the ore-barrage."

"I'll go! My suit is here."

A WILLING volunteer rushed out to the ore-shed. The Gamma rays, which in the helio-room of the Planetara came so unwelcome to Snap and me, were loosed.

"Can you send, Peter?" Grantline demanded.

"Yes, with more power."

"Use it."

Johnny dictated the message of his location which we received. In his incautious excitement he ignored the secret code.

An interval passed. The ore was occulted again. No message had come from us—just Snap's routine signal in the weak infra-red, which we hoped Grantline would not get.

The men crowding Grantline's instrument room waited in tense silence. Then Grantline tried the telescope. Its current weakened the lights with the drain upon the distributors, and cooled the room with a sudden deadly chill as the Erentz insulating system slowed down.

The duty man looked suddenly frightened. "You'll bulge out our walls, Commander. The internal pressure—"

"We'll chance it."

They picked up the image of the Planetara! It came from the telescope and shone clear on the grid—the segment of star-field with a tiny, cigar-shaped blob. Clear enough to be unmistakable. The Planetara! Here now over the Moon, almost directly overhead, poised at what the altimeter scale showed to be a fraction under thirty thousand miles.

The men gazed in awed silence. The Planetara coming....

But the altimeter needle was motionless. The Planetara was hanging poised.

A sudden gasp went about the room. The men stood with whitening faces, gazing at the Planetara's image. And at the altimeter needle. It was moving. The Planetara was descending. But not with an orderly swoop.

The image showed the ship clearly. The bow tilted up, then dipped down. But then in a moment it swung up again. The ship turned partly over. Righted itself. Then swayed again, drunkenly.

The watching men were stricken into horrified silence. The Planetara's image momentarily, horribly, grew larger. Swaying. Then turning completely over, rotating slowly end over end.

The Planetara, out of control, was falling!

CHAPTER XXI
The Wreck of the Planetara

ON the Planetara, in the helio-room, Snap and I stood with Moa's weapon upon us. Miko held Anita. Triumphant. Possessive. Then as she struggled, a gentleness came to this strange Martian giant. Perhaps he really loved her. Looking back on it, I sometimes think so.

"Anita, do not fear me." He held her away from him. "I would not harm you. I want your love." Irony came to him. "And I thought I had killed you! But it was only your brother."

He partly turned. I was aware of how alert was his attention. He grinned. "Hold them, Moa—don't let them do anything foolish. So, Anita, you were masquerading to spy upon me? That was wrong of you." He was again ironic.

Anita had not spoken. She held herself tensely away from Miko; she had flashed me a look—just one. What horrible mischance to have brought this catastrophe!

The completion of Grantline's message had come unnoticed by us all.

"Look! Grantline again!" Snap said abruptly.

But the mirrors were steadying. We had no recording-tape apparatus; the rest of the message was lost. The mirrors pulsed and then steadied.

No further message came. There was an interval while Miko waited. He held Anita in the hollow of his great arm.

"Quiet, little bird. Do not fear me. I have work to do, Anita—this is our great adventure. We will be rich, you and I. All the luxuries three worlds can offer, all for us when this is over. Careful, Moa! This Haljan has no wit."

Well could he say it! I, who had been so witless to let this come upon us! Moa's weapon prodded me. Her voice hissed at me with all the venom of a reptile enraged. "So that was your game, Gregg Haljan! And I was so graceless to admit love for you!"

SNAP murmured in my ear, "Don't move, Gregg! She's reckless."

She heard it. She whirled on him. "We have lost George Prince, it seems. Well, we will survive without his ore knowledge. And you, Dean—and this Haljan—mark me, I will kill you both if you cause trouble!"

Miko was gloating. "Don't kill them yet, Moa. What was it Grantline said? Near the crater of Archimedes? Ring us down, Haljan! We'll land."

He signaled the turret. Gave Coniston the Grantline message, and audiphoned it below to Hahn. The news spread about the ship. The bandits were jubilant.

"We'll land now, Haljan. Ring us down. Come, Anita and I will go with you to the turret."

I found my voice. "To what destination?"

"Near Archimedes. The Apennine side. Keep well away from the Grantline camp. We will probably sight it as we descend."

There was no trajectory needed. We were almost over Archimedes now. I could drop us with a visible, instrumental course. My mind was whirling with a confusion of thoughts. What could we do? What could we dare attempt to do? I met Snap's gaze.[92]

"Ring us down, Gregg," he said quietly.

I nodded. I pushed Moa's weapon away. "You don't need that. I obey orders."

WE went to the turret. Moa watched me and Snap, a grim, cold Amazon. She avoided looking at Anita, whom Miko helped down the ladders with a strange mixture of courtierlike grace and amused irony. Coniston gazed at Anita with falling jaw.

"I say! Not George Prince? The girl—"

"No time for argument now," Miko commanded. "It's the girl, masquerading as her brother. Get below, Coniston. Haljan takes us down."

The astounded Englishman continued gazing at Anita. "I mean to say, where to on the Moon? Not to encounter Grantline at once, Miko? Our equipment is not ready."

"Of course not. We will land well away. He won't be suspicious—we can signal him again after we land. We will have time to plan, to assemble the equipment. Get below, I told you."

The reluctant Coniston left us. I took the controls. Miko, still holding Anita as though she were a child, sat beside me. "We will watch him, little Anita. A skilled fellow at this sort of work."

I rang my signals for the shifting of the gravity plates. The answer should have come from below within a second or two. But it did not. Miko regarded me with his great bushy eyebrows upraised.

"Ring again, Haljan."

I duplicated. No answer. The silence was frightening. Ominous.

Miko muttered, "That accursed Hahn. Ring again!"

I sent the imperative emergency demand.

NO answer. A second or two. Then all of us in the turret were startled. Transfixed. From below came a sudden hiss. It sounded in the turret: it came from shifting-room call-grid. The hissing of the pneumatic valves of the plate-shifters in the lower control room. The valves were opening; the plates automatically shifting into neutral, and disconnecting!

An instant of startled silence. Miko may have realized the significance of what had happened. Certainly Snap and I did. The hissing ceased. I gripped the emergency plate-shifter switch which hung over my head. Its disc was dead! The plates were dead in neutral. In the positions they were only placed while in port! And their shifting mechanisms were imperative!

I was on my feet. "Snap! Good God, we're in neutral!"

Miko, if he had not realized it before, was aware if it now. The Moon-disc moved visibly as the Planetara lurched. The vault of the heavens was slowly swinging.

Miko ripped out a heavy oath. "Haljan! What is this?"

He stood up, still holding Anita. But there was nothing that he could do in this emergency. "Haljan—what—"

The heavens turned with a giant swoop. The Moon was over us. It swung in dizzying arc. Overhead, then back past our stern; under us, then appearing over our bow.

The Planetara had turned over. Upending. Rotating, end over end.

For a moment or two I think all of us in that turret stood and clung. The Moon-disc, the Earth, Sun and all the stars were swinging past our windows. So horribly dizzying. The Planetara seemed lurching and tumbling. But it was an optical effect only. I stared with grim determination at my feet. The turret seemed to steady.

Then I looked again. That horrible swoop of all the heavens! And the Moon, as it went past, seemed expanded. We were falling! Out of control, with the Moon-gravity pulling us inexorably down!

"That accursed Hahn—" Miko, stricken with his lack of knowledge of these controls, was wholly confused.

A MOMENT only had passed. My fancy that the Moon-disc was enlarged was merely the horror of my imagination. We had not fallen far enough yet for that.

But we were falling. Unless I could do something, we would crash upon the Lunar surface.

Anita, killed in this Planetara turret. The end of everything for us.

Action came to me. I gasped, "Miko, you stay here! The controls are dead! You stay here—hold Anita."

I ignored Moa's weapon which she was still clutching mechanically. Snap thrust her away.

"Sit back! Let us alone! We're falling! Don't you understand?"

This deadly danger, to level us all! No longer were we captors and captured. Not brigands for this moment. No thought of Grantline's treasure! Trapped humans only! Leveled by the common, instinct of self-preservation. Trapped here together, fighting for our lives.

Miko gasped. "Can you—check us? What happened?"

"I don't know. I'll try."

I stood clinging. This dizzying whirl! From the audiphone grid Coniston's voice sounded.

"I say, Haljan, something's wrong! Hahn doesn't signal."

The look-out in the forward tower was clinging to his window. On the deck below our turret a member of the crew appeared, stood lurching for a moment, then shouted, and turned and ran, swaying, aimless. From the lower hull-corridors our grids sounded with the tramping of running steps. Panic among the crew was spreading over the ship. A chaos below decks.

I PULLED at the emergency switch again. Dead....

But down below there was the manual controls.

"Snap, we must get down. The signals."

"Yes."

Coniston's voice came like a scream from the grid. "Hahn is dead—the controls are broken! Hahn is dead!"

We barely heard him. I shouted, "Miko—hold Anita! Come on, Snap!"

We clung to the ladders. Snap was behind me. "Careful, Gregg! Good God!"

This dizzying whirl. I tried not to look. The deck under me was now a blurred kaleidoscope of swinging patches of moonlight and shadow.

We reached the deck. Ran, swaying, lurching.

It seemed that from the turret Anita's voice followed us. "Be careful!"

Within the ship our senses steadied. With the rotating, reeling, heavens shut out, there were only the shouts and tramping steps of the panic-stricken crew to mark that anything was amiss. That, and a pseudo-sensation of lurching caused by the pulsing of gravity—a pull when the Moon was beneath our hull to combine its force with our magnetizers; a lightening when it was overhead. A throbbing, pendulum lurch—that was all.

We ran down to the corridor incline. A white-faced member of the crew, came running up.

"What's happened? Haljan, what's happened?"

"We're falling!" I gripped him. "Get below. Come on with us!"

But he jerked away from me. "Falling?"

A steward came running. "Falling? My God!"

Snap swung at them. "Get ahead of us! The manual controls—our only chance—we need all you men at the compressor pumps!"

But it was an instinct to try and get on deck, as though here below we were rats caught in a trap. The men tore away from me and ran. Their shouts of panic resounded through the dim, blue-lit corridors.

CONISTON came lurching from the control room. "I say—falling! Haljan, my God, look at him!"

Hahn was sprawled at the gravity-plate switchboard. Sprawled, head-down. Dead. Killed by something? Or a suicide?

I bent over him. His hands gripped the main switch. He had ripped it loose. And his left hand had reached and broken the fragile line of tubes that intensified the current of the pneumatic plate-shifters. A suicide? With his last frenzy determined to kill us all?

Then I saw that Hahn had been killed! Not a suicide! In his hand he gripped a small segment of black fabric, a piece torn from an invisible cloak? Was it?

The questions were swept away by the necessity for action. Snap was rigging the hand-compressors. If he could get the pressure back in the tanks....

I swung on Coniston. "You armed?"

"Yes." He was white-faced and confused, but not in a panic. He showed me his heat-ray cylinder. "What do you want me to do?"

"Round up the crew. Get all you can. Bring them here to man these pumps."

He dashed away. Snap shouted after him. "Kill them down if they argue!"

Miko's voice sounded from the turret call grid: "Falling! Haljan, you can see it now! Check us!"

I did not answer that. I pumped with Snap.

Desperate moments. Or was it an hour? Coniston brought the men. He stood over them with menacing weapon.

We had all the pumps going. The pressure rose a little in the tanks. Enough to shift a bow-plate. I tried it. The plate slowly clicked into a new combination. A gravity repulsion just in the bow-tip.

I SIGNALED Miko. "Have we stopped swinging?"

"No. But slower."

I could feel it, that lurch of the gravity. But not steady now. A limp. The tendency of our bow was to stay up.

"More pressure, Snap."

"Yes."

One of the crew rebelled, tried to bolt from the room. "God, we'll crash, caught in here!"

Coniston shot him down.

I shifted another bow-plate. Then two in the stern. The stern-plates seemed to move more readily than the others.

"Run all the stern-plates," Snap advised.

I tried it. The lurching stopped. Miko called. "We're bow down. Falling!"

But not falling free. The Moon-gravity pull upon us was more than half neutralized.

"I'll go up, Snap, and try the engines. You don't mind staying down? Executing my signals?"

"You idiot!" He gripped my shoulders. His eyes were gleaming, his face haggard, but his pale lips twitched with a smile.

"Maybe it's good-by, Gregg. We'll fall—fighting."

"Yes. Fighting. Coniston, you keep the pressure up."

With the broken set-tubes it took nearly all the pressure to maintain the few plates I had shifted. One slipped back to neutral. Then the pumps gained on it, and it shifted again.

I dashed up to the deck. Ah, the Moon was so close now! So horribly close! The deck shadows were still. Through the forward bow windows the Moon surface glared up at us.

I REACHED the turret. The Planetara was steady. Pitched bow-down, half falling, half sliding like a rocket downward. The scarred surface of the Moon spread wide under us.

These last horrible minutes were a blur. And there was always Anita's face. She left Miko. Faced with death, he sat clinging. Ignoring her, Moa, too, sat apart. Staring—

And Anita crept to me. "Gregg, dear one. The end...."

I tried the electronic engines from the stern, setting them in the reverse. The streams of their light glowed from the stern, forward along our hull, and flared down from our bow toward the Lunar surface. But no atmosphere was here to give resistance. Perhaps the electronic streams checked our fall a little. The pumps gave us pressure, just in the last minutes, to slide a few of the hull-plates. But our bow stayed down. We slid, like a spent rocket falling.

I recall the horror of that expanding Lunar surface. The maw of Archimedes yawning. A blob. Widening to a great pit. Then I saw it was to one side. Rushing upward.

A phantasmagoria of uprushing crags. Black and gray. Spires tinged with Earth-light.

"Gregg, dear one—good-by."

Her gentle arms around me. The end of everything for us. I recall murmuring, "Not falling free, Anita. Some hull-plates are set."

My dials showed another plate shifting, checking us a little further. Good old Snap.

I calculated the next best plate to shift. I tried it. Slid it over. Good old Snap....

Then everything faded but the feeling of Anita's arms around me.

"Gregg, dear one—"

The end of everything for us....

There was an up-rush of gray-black rock.

An impact....

CHAPTER XXII
The Hiss of Death

I OPENED my eyes to a dark blur of confusion. My shoulder hurt—a pain shooting through it. Something lay like a weight on me. I could not seem to move my left arm. Very queer! Then I moved it, and it hurt. I was lying twisted: I sat up. And with a rush, memory came. The crash was over. I am not dead. Anita—

She was lying beside me. There was a little light here in this silent blur—a soft, mellow Earth-light filtering in the window. The weight on me was Anita. She lay sprawled, her head and shoulders half way across my lap.

Not dead! Thank God, not dead! She moved. Her arms went around me, and I lifted her. The Earth-light glowed on her pale face; but her eyes opened and she faintly smiled.

"It's past, Anita! We've struck, and we're still alive."

I held her as though all life's turgid danger were powerless to touch us.

But in the silence my floating senses were brought back to reality by a faint sound forcing itself upon me. A little hiss. The faintest murmuring breath like a hiss. Escaping air!

I cast off her clinging arms. "Anita, this is madness!"

FOR minutes we must have been lying there in the heaven of our embrace. But air was escaping! The Planetara's dome was broken—or cracked—and our precious air was hissing out.

Full reality came to me at last. I was not seriously injured. I found that I could move freely. I could stand. A twisted shoulder, a limp left arm, but they were better in a moment.

And Anita did not seem to be hurt. Blood was upon her. But not her blood.

Beside Anita, stretched face down on the turret grid, was the giant figure of Miko. The blood lay in a small pool against his face. A widening pool.

Moa was here. I thought her body twitched; then was still. This soundless wreckage! In the dim glow of the wrecked turret with its two motionless, broken human figures, it seemed as though Anita and I were ghouls prowling. I saw that the turret had fallen over to the Planetara's deck. It lay dashed against the dome-side.

The deck was aslant. A litter of wreckage. A broken human figure showed—one of the crew, who at the last must have come running up. The forward observation tower was down on the chart-room roof: in its metal tangle I thought I could see the legs of the tower look-out.[96]

So this was the end of the brigands' adventure! The Planetara's last voyage! How small and futile are human struggles! Miko's daring enterprise—so villainous, inhuman—brought all in a few moments to this silent tragedy. The Planetara had fallen thirty thousand miles. But why? What had happened to Hahn? And where was Coniston, down in this broken hull?

And Snap. I thought suddenly of Snap.

I CLUTCHED at my wandering wits. This inactivity was death. The escaping air hissed in my ears. Our precious air, escaping away into the vacant desolation of the Lunar emptiness. Through one of the twisted, slanting dome-windows a rocky spire was visible. The Planetara lay bow-down, wedged in a jagged cradle of Lunar rock. A miracle that the hull and dome had held together.

"Anita, we must get out of here!"

I thought I was fully alert now. I recalled that the brigands had spoken of having partly assembled their Moon equipment. If only we could find suits and helmets!

"We must get out," I repeated. "Get to Grantline's camp."

"Their helmets are in the forward storage room, Gregg. I saw them there."

She was staring at the fallen Miko and Moa. She shuddered and turned away and gripped me. "In the forward storage room, by the port of the emergency lock-exit."

If only the exit locks would operate! We must get out of here, but find Snap first. Good old Snap! Would we find him lying dead?

We climbed from the slanting, fallen turret, over the wreckage of the littered deck. It was not difficult, a lightness was upon us. The Planetara's gravity-magnetizers were dead: this was only the light Moon-gravity pulling us.

"Careful, Anita. Don't jump too freely."

We leaped along the deck. The hiss of the escaping pressure was like a clanging gong of warning to tell us to hurry. The hiss of death so close!

"Snap—" I murmured.

"Oh, Gregg. I pray we may find him alive—!"

"And get out. We've got to rush it. Get out and find the Grantline camp."

BUT how far? Which way? I must remember to take food and water. If the helmets were equipped with admission ports. If we could find Snap. If the exit locks would work to let us out.

With a fifteen foot leap we cleared a pile of broken deck chairs. A man lay groaning near them. I went back with a rush. Not Snap! A steward. He had been a brigand, but he was a steward to me now.

"Get up! This is Haljan. Hurry, we must get out of here. The air is escaping!"

But he sank back and lay still. No time to find if I could help him: there were Anita and Snap to save.

We found a broken entrance to one of the descending passages. I flung the debris aside and cleared it. Like a giant of strength with only this Moon-gravity holding me, I raised a broken segment of the superstructure and heaved it back.

Anita and I dropped ourselves down the sloping passage. The interior of the wrecked ship was silent and dim. An occasional passage light was still burning. The passage and all the rooms lay askew. Wreckage everywhere: but the double-dome and hull-shell had withstood the shock. Then I realized that the Erentz system was slowing down. Our heat, like our air, was escaping, radiating away, a deadly chill settling upon everything. And our walls were bulging. The silence and the deadly chill of death would soon be here in these wrecked corridors. The end of the Planetara. I wondered vaguely if the walls would explode.

We prowled like ghouls. We did not see Coniston. Snap had been by the shifter-pumps. We found him in the oval doorway. He lay sprawled. Dead? No, he moved. He sat up before we could get to him. He seemed confused, but his senses clarified with the movement of our figures over him.

"Gregg! Why, Anita!"

"Snap! You're all right? We struck—the air is escaping."

HE pushed me away. He tried to stand. "I'm all right. I was up a minute ago. Gregg, it's getting cold. Where is she? I had her here—she wasn't killed. I spoke to her."

Irrational!

"Snap!" I held him, shook him. "Snap, old fellow!"

He said, normally. "Easy, Gregg. I'm all right now."

Anita gripped him. "Who, Snap?"

"She! There she is."

Another figure was here! On the grid-floor by the door oval. A figure partly shrouded in a broken invisible cloak and hood. An invisible cloak! I saw a white face with opened eyes regarding me. The face of a girl.

Venza!

I bent down. "You!"

Anita cried, "Venza!"

Venza here? Why—how—my thoughts swept away. Venza here, dying? Her eyes closed. But she murmured to Anita. "Where is he? I want him."

Dying? I murmured impulsively, "Here I am, Venza dear." Gently, as one would speak with gentle sympathy to humor the dying. "Here I am, Venza."

But it was only the confusion of the shock upon her. And it was upon us all. She pushed at Anita. "I want him." She saw me. This whimsical Venus girl! Even here as we gathered, all of us blurred by the shock, confused in the dim, wrecked ship with the chill of death coming—even here she could make a jest. Her pale lips smiled.

"You, Gregg. I'm not hurt—I don't think I'm hurt." She managed to get herself up on one elbow. "Did you think I wanted you with my dying breath? Why, what conceit! Not you, Handsome Haljan! I was calling Snap."

HE was down to her. "We're all right, Venza. It's over. We must get out of the ship—the air is escaping."

We gathered in the oval doorway. We fought the confusion of panic.

"The exit port is this way."

Or was it? I answered Snap, "Yes, I think so."

The ship suddenly seemed a stranger to me. So cold. So vibrationless. Broken lights. These slanting, wrecked corridors. With the ventilating fans stilled, the air was turning fetid. Chilling. And thinning, with escaping pressure, rarifying so that I could feel the grasp of it in my lungs and the pin-pricks of my burning cheeks.

We started off. Four of us, still alive in this silent ship of death. My blurred thoughts tried to cope with it all. Venza here. I recalled how she had bade me create a diversion when the women passengers were landing on the asteroid. She had carried out her purpose! In the confusion she had not gone ashore. A stowaway here. She had secured the cloak. Prowling, to try and help us, she had come upon Hahn. Had seized his ray-cylinder and struck him down, and been herself knocked unconscious by his dying lunge, which also had broken the tubes and wrecked the Planetara. And Venza, unconscious, had been lying here with the mechanism of her cloak still operating, so that we did not see her when we came and found why Hahn did not answer my signals.

"It's here, Gregg."

Snap and I lifted the pile of Moon equipment. We located four suits and helmets and the mechanisms to operate them.

"More are in the chart-room," Anita said.

But we needed no others. I robed Anita, and showed her the mechanisms.

"Yes. I understand."

SNAP was helping Venza. We were all stiff from the cold; but within the suits and their pulsing currents, the blessed warmth came again.

The helmets had admission ports through which food and drink could be taken. I stood with my helmet ready. Anita, Venza and Snap were bloated and grotesque beside me. We had found food and water here, assembled in portable cases which the brigands had prepared. Snap lifted them, and signed to me he was ready.

My helmet shut out all sounds save my own breathing, my pounding heart, and the murmur of the mechanism. The blessed warmth and pure air were good.

We reached the hull port-locks. They operated! We went through in the light of the head-lamps over our foreheads.

I closed the locks after us. An instinct to keep the air in the ship for the other trapped humans lying there.

We slid down the sloping side of the Planetara. We were unweighted, irrationally agile with the slight gravity. I fell a dozen feet and landed with barely a jar.

We were out on the Lunar surface. A great sloping ramp of crags stretched down before us. Gray-black rock tinged with Earth-light. The Earth hung amid the stars in the blackness overhead like a huge section of glowing yellow ball.

THIS grim, desolate, silent landscape! Beyond the ramp, fifty feet below us, a tumbled naked plain stretched away into blurred distance. But I could see mountains off there. Behind us the towering, frowning rampart-wall of Archimedes loomed against the sky.

I had turned to look back at the Planetara. She lay broken, wedged between spires of upstanding rock. A few of her lights still gleamed. The end of the Planetara!

The three grotesque figures of Anita, Venza and Snap had started off. Hunchback figures with the tanks mounted on their shoulders. I bounded and caught them. I touched Snap. We made audiphone contact.

"Which way do you think?" I demanded.

"I think this way, down the ramp. Away from Archimedes, toward the mountains. It shouldn't be too far."

"You run with Venza. I'll hold Anita."

He nodded. "But we must keep together, Gregg."

We could soon run freely. Down the ramp, out over the tumbled plain. Bounding, grotesque leaping strides. The girls were more agile, more skilful. They were soon leading us. The Earth-shadows of their figures leaped beside them. The Planetara faded into the distance behind us. Archimedes stood back there. Ahead, the mountains came closer.

An hour perhaps. I lost count of time. Occasionally we stopped to rest. Were we going toward the Grantline camp? Would they see our tiny waving headlights?

Another interval. Then far ahead of us on the ragged plain, lights showed! Moving tiny spots of light! Headlights on helmeted figures!

We ran, monstrously leaping. A group of figures were off there. Grantline's party? Snap gripped me.

"Grantline! We're safe, Gregg! Safe!"

HE took his bulb-light from his helmet: we stood in a group while he waved it. A semaphore signal.

"Grantline?"

And the answer came. "Yes. You, Dean?"

Their personal code. No doubt of this—it was Grantline, who had seen the Planetara fall and had come to help us.

I stood then with my hand holding Anita. And I whispered, "It's Grantline! We're safe, Anita, my darling!"

Death had been so close! Those horrible last minutes on the Planetara had shocked us, marked us.

We stood trembling. And Grantline and his men came bounding up.

A helmeted figure touched me. I saw through the helmet-pane the visage of a stern-faced, square-jawed, youngish man.

"Grantline? Johnny Grantline?"

"Yes," said his voice at my ear-grid. "I'm Grantline. You're Haljan? Gregg Haljan?"

They crowded around us. Gripped us to hear our explanations.

Brigands! It was amazing to Johnny Grantline. But the menace was over now, over as soon as Grantline had realized its existence. As though the wreck of the Planetara were foreordained by an all-wise Providence, the brigands' adventure had come to tragedy.

We stood for a time discussing it. Then I drew apart, leaving Snap with Grantline. And Anita joined me. I held her arm so that we had audiphone contact.

"Anita, mine."

"Gregg, dear one."

Murmured nothings which mean so much to lovers!

AS we stood in the fantastic gloom of the Lunar desolation, with the blessed Earth-light on us, I sent up a prayer of thankfulness. Not that a hundred millions of treasure were saved. Not that the attack upon Grantline had been averted. But only that Anita was given back to me. In moments of greatest emotion the human mind individualizes. To me, there was only Anita.

Life is very strange! The gate to the shining garden of our love seemed swinging wide to let us in. Yet I recall that a vague fear still lay on me. A premonition?

I felt a touch on my arm. A bloated helmet visor was thrust near my own. I saw Snap's face peering at me.

"Grantline thinks we should return to the Planetara. Might find some of them alive."

Grantline touched me. "It's only humanity."

"Yes," I said.

We went back. Some ten of us—a line of grotesque figures bounding with slow, easy strides over the jagged, rock-strewn plain. Our lights danced before us.

The Planetara came at last into view. My ship. Again that pang swept me as I saw her. This, her last resting place. She lay here in her open tomb, shattered, broken, unbreathing. The lights on her were extinguished. The Erentz system had ceased to pulse—the heart of the dying ship, for a while beating faintly, but now at rest.

We left the two girls with some of Grantline's men at the admission port. Snap, Grantline and I, with three others, went inside. There still seemed to be air, but not enough so that we dared remove our helmets.

It was dark inside the wrecked ship. The corridors were black; the hull control-rooms were dimly illumined with Earth-light straggling through the windows.

This littered tomb! Already cold and silent with death. We stumbled over a fallen figure. A member of the crew.

GRANTLINE straightened from examining him.

"Dead."

Earth-light fell on the horrible face. Puffed flesh, bloated red from the blood which had oozed from its pores in the thinning air. I looked away.

We prowled further. Hahn lay dead in the pump-room.

The body of Coniston should have been near here. We did not see it.

We climbed up to the slanting littered deck. The dome had not exploded, but the air up here had almost all hissed away.

Again Grantline touched me. "That the turret?"

"Yes."

No wonder he asked! The wreckage was all so formless.

We climbed after Snap into the broken turret room. We passed the body of that steward who just at the end had appealed to me and I had left dying. The legs of the forward look-out still poked grotesquely up from the wreckage of the observatory tower where it lay smashed down against the roof of the chart-room.

We shoved ourselves into the turret. What was this? No bodies here! The giant Miko was gone! The pool of his blood lay congealed into a frozen dark splotch on the metal grid.

And Moa was gone! They had not been dead. Had dragged themselves out of here, fighting desperately for life. We would find them somewhere around here.

But we did not. Nor Coniston. I recalled what Anita had said: other suits and helmets had been here in the nearby chart-room. The brigands had taken them, and food and water doubtless, and escaped from the ship, following us through the lower admission ports only a few minutes after we had gone out.

WE made careful search of the entire ship. Eight of the bodies which should have been here were missing: Miko, Moa, Coniston, and five of the steward-crew.

We did not find them outside. They were hiding near here, no doubt, more willing to take their chances than to yield now to us. But how, in all this Lunar desolation, could we hope to locate them?

"No use," said Grantline. "Let them go. If they want death—well, they deserve it."

But we were saved. Then, as I stood there, realization leaped at me. Saved? Were we not indeed fatuous fools?

In all these emotion-swept moments since we had encountered Grantline, memory of that brigand ship coming from Mars had never once occurred to Snap or me!

I told Grantline now. His eyes through the visor stared at me blankly.

"What!"

I told him again. It would be here in eight days. Fully manned and armed.

"But Haljan, we have almost no weapons! All my Comet's space was taken with mining equipment and the mechanisms for my camp. I can't signal Earth! I was depending on the Planetara!"

It surged upon us. The brigand menace past? We were blindly congratulating ourselves on our safety! But it would be eight days or more before in distant Ferrok-Shahn the non-arrival of the Planetara would cause any real comment. No one was searching for us—no one was worried over us.

No wonder the crafty Miko was willing to take his chances out here in the Lunar wilds! His ship, his reinforcements, his weapons were coming rapidly!

And we were helpless. Almost unarmed. Marooned here on the Moon with our treasure!

CHAPTER XXIII
The Prowling Watchman

"TRY it again," Snap urged. "Good God, Johnny, we've got to raise some Earth station! Chance it! Use your power—run it up to the full. Chance it!"

We were gathered in Grantline's instrument room. The duty-man, with blanched grim face, sat at his senders. The Grantline crew shoved close around us, tense and silent.

Above everything we must make some Earth station aware of our plight. Conditions were against us. There were very few observers, in the high-powered Earth stations who knew that an exploring party was on the Moon. Perhaps none of them. The Government officials who had sanctioned the expedition—and Halsey and his confrères in the Detective Bureau—were not anticipating trouble now. The Planetara was supposed to be well on her course to Ferrok-Shahn. It was when she was due to return that Halsey would be alert.

And it seemed, too, that nature was against us. The bulging half-Earth¹ hung poised near the zenith over our little crater. Its rotation through the hours was clearly visible. We timed our signals when the western hemisphere was facing us. But nature was against us. No clouds, no faintest hint of mist could fog the airless Lunar surface. But there were continuous clouds over the Americas.

1: Between the half and the full illumined disc, the complete Earth now was some ten days old.

"Try it again," Snap urged.

THERE bulging walls! Grantline used his power far beyond the limits of safety. He cut down his lights; the telescope intensifiers were permanently disconnected; the ventilators were momentarily stilled, so that the air here in the little room crowded with men rapidly grew fetid. All to save power pressure, that the vital Erentz system might survive.

Even so it was strained to the danger point. The walls seemed to bulge outward with the pressure of the room, the aluminite braces straining and creaking. And our heat was radiating away; the deadly chill of space crept in.

"Again!" ordered Grantline.

The duty-man flung on the power in rhythmic pulses. In the silence the tubes hissed. The light sprang through the banks of rotating prisms, intensified up the scale until, with a vague, almost invisible beam, it left the last swaying mirror and leaped through our overhead dome into space.

"Commander!" The duty-man's voice carried an appeal. These bulging walls! If they cracked, or even sprung a serious leak, the camp would be uninhabitable....

"Enough," said Grantline. "Switch it off. We'll let it go at that for now."

It seemed that every man in the room had been holding his breath in the darkness. The lights came on again: the Erentz motors accelerated to normal. The strain on the walls eased up, and the room began warming.

Had the Earth caught our signal? We did not want to waste the power to find out. Our receivers were disconnected. If an answering signal came, we could not know it. One of the men said:

"Let's assume they saw us." He laughed, but it was a high-pitched, tense laugh. "We don't dare even use the telescope. Our rescue ship will be right overhead, visible to the naked eye before we see it. Three days more—that's what I'll give it."

BUT the three days passed, and no rescue ship came. The Earth was almost at the full. We tried signaling again. Perhaps it got through—we did not know. But our power was weaker now. The wall of one of the rooms sprang a leak, and the men were hours repairing it. I did not say so, but never once did I feel that our signals were seen on Earth. Those cursed clouds! The Earth almost everywhere seemed to have poor visibility.

Four of our eight days of grace were all too soon passed. The brigand ship must be half-way here by now.

They were busy days for us. If we could have captured Miko and his band, our danger would have been less imminent. With the treasure insulated so that its Gamma rays could not betray us, and our camp in darkness, the arriving brigand ship might never find us. But Miko knew our location: he would signal his oncoming ship when it was close and lead it to us.

Three times during those days—and the days which followed them—Grantline sent out searching parties. But it was unavailing. Miko, Moa and Coniston, with their five underlings, could not be found. We searched all the territory from the camp to the Planetara, and off to the foot-crags of Archimedes, and a score of miles into the flatness of the Mare Imbrium. There was no sign of the brigands. Yet we knew they could be near here—it was so easy to hide amid the tumbled crags, the ravines, the gullies, the numberless craters and pit-holes: or underground in the vast honeycombed subterranean recesses.

WE had at first hoped that the brigands might have perished. But that was soon dispelled! I went—about the third day—with the party that was sent to the Planetara. We wanted to salvage such of its equipment, its unbroken power units, as might be available. And Snap and I had worked out an idea which we thought might be of service. We needed some of the Planetara's smaller gravity-plate sections. Those in Grantline's wrecked little Comet had stood so long that their radiations had gone dead. But the Planetara's were still efficacious.

We secured the fragments of Newtonia.² But our hope that Miko might have perished was dashed. He too had returned to the Planetara! The evidence was clear before us. The vessel was stripped of all its power units save those which were dead and useless. The last of the food and water stores was taken. The weapons in the chart-room—the Benson curve-lights, bullet projectors, and heat-rays—had vanished.

2: An allusion to the element Newtonia, named in memory of the great founder of celestial mechanics, Sir Isaac Newton. Artificially electronized, this metal element may be charged either positively or negatively, thus to attract or repell other masses of matter. The gravity plates of all space-ships were built of it.

Other days passed. The Earth reached the full, and began waning. The twenty-eight day Lunar night was in its last half. No rescue ship came from Earth. We had ceased our efforts to signal, for we needed all our power to maintain ourselves. The camp would be in a state of siege. That was the best we could hope for. We had a few short-range weapons, such as Bensons, heat-rays and rifles. A few hundred feet of effective range was the most any of them could obtain. The heat-rays—in giant form one of the most deadly weapons on Earth—were only slowly efficacious on the airless Moon. Striking an intensely cold surface, their warming radiations, without atmosphere to aid them, were slow to act. Even in a blasting heat-beam a man in his Erentz helmet-suit could withstand the ray for several minutes.

WE were, however, well equipped with explosives. Grantline had brought a large supply for his mining operations, and much of it was still unused. We had, also, an ample stock of oxygen fuses, and a variety of oxygen light flares in small fragile glass-globes.

It was to use these explosives against the brigands that Snap and I were working out our scheme with the gravity-plates. The brigand ship would come with giant projectors and with some thirty men. If we could hold out against them for a time, the fact that the Planetara was missing would bring us help from Earth.

"A month," said Grantline. "A month at the most. If we can hold them off that long—even in a week or two help may come."

Another day. A tenseness fell on us all, despite the absorption of our feverish activities. To conserve the power, the camp was almost dark, we lived in dim, chill rooms, with just a few weak spots of light outside to mark the watchmen on their rounds. We did not use the telescope,³ but there was scarcely an hour when one or the other of the men was not sitting on a cross-piece up in the dome of the little instrument room, casting tense searching gaze into the black, starry firmament. A ship might appear at any time now—a rescue ship from Earth, or the brigands from Mars.

3: An old-fashioned telescope, of limited field and needing no electronic power, would have been immensely serviceable to Grantline, but his was of the more modern type.

ANITA and Venza during these days could aid us very little save by their cheering words. They moved about the rooms, trying to inspire us; so that all the men, when they might have been humanly sullen and cursing their fate, were turned to grim activity, or grim laughter, making a joke of this coming siege. The morale of the camp now was perfect. An improvement indeed over the inactivity of the former peaceful weeks!

Grantline mentioned it to me. "We'll put up a good fight, Haljan. These fellows from Mars will know they've had a task before they ever sail off with this treasure."

I had many moments alone with Anita. I need not mention them. It seemed that our love was crossed by the stars, with an adverse fate dooming it. And Snap and Venza must have felt the same. Among the men we were always quietly, grimly active. But alone.... I came upon Snap once with his arms around the little Venus girl. I heard him say:

"Accursed luck! That you and I should find each other too late, Venza. We could have a mighty lot of fun in Great-New York together."

"Snap, we will!"

As I turned away, I murmured: "And, pray God, so will Anita and I."

The girls slept together in a small room of the main building. Often during the time of sleep, when the camp was stilled except for the night watch, Snap and I would sit in the corridor near the girls' door-grid, talking of that time when we would all be back on our blessed Earth.

OUR eight days of grace were passed. The brigand ship was due—now, to-morrow, or the next day.

I recall, that night, my sleep was fitfully uneasy. Snap and I had a cubby together. We talked, and made futile plans. I went to sleep, but awakened after a few hours. Impending disaster lay heavily on me. But there was nothing abnormal nor unusual in that!

Snap was asleep. I was restless, but I did not have the heart to awaken him. He needed what little repose he could get. I dressed, left our cubby and wandered out into the corridor of the main building.

It was cold in the corridor, and gloomy with the weak blue light. An interior watchman passed me.

"All as usual, Haljan."

"Nothing in sight?"

"No. They're looking."

I went through the connecting corridor to the adjacent building. In the instrument-room several of the men were gathered, scanning the vault overhead.

"Nothing, Haljan."

I stayed with them awhile, then wandered away. The outside man met me near the admission lock-chambers of the main building. The duty-man here sat at his controls, raising the air-pressure in the locks through which the outside watchman was coming. The relief sat here in his bloated suit, with his helmet on his knees. It was Wilks.

"Nothing yet, Haljan. I'm going up to the peak of the crater to see if anything is in sight. I wish that damnable brigand ship would come and get it over with."

Instinctively we all spoke in half whispers, the tenseness bearing in on us.

The outside man came out of his helmet. He was white and grim, but he grinned at Wilks.

"All is usual." He tried the familiar jest at Wilks, but his voice was flat: "Don't let the Earthlight get you!"

Wilks went out through the portes—a process of no more than a minute. I wandered away again through the corridors.

I SUPPOSE it was half an hour later that I chanced to be gazing through a corridor window. The lights along the rocky cliff-edge were tiny blue spots. The head of the stairway leading down to the abyss of the crater floor was visible. The bloated figure of Wilks was just coming up. I watched him for a moment making his rounds. He did not stop to inspect the lights. That was routine; I thought it queer that he passed them.

Another minute passed. The figure of Wilks went with slow bounds over toward the back of the ledge where the glassite shelter housed the treasure. It was all dark off there. Wilks went into the gloom, but before I lost sight of him he came back. As though he had changed his mind he headed for the foot of the staircase which led up the cliff-face to where, at the peak of the little crater, five hundred feet above us, the narrow observatory platform was perched. He climbed with easy bounds, the light on his helmet bobbing in the gloom.

I stood watching. I could not tell why there seemed to be something queer about Wilks' actions. But I was struck with it, nevertheless. I watched him disappear over the peak of the summit.

Another minute went by. Wilks did not reappear. I thought I could make out his light on the platform up there. Then abruptly a tiny white beam was waving from the observatory platform! It flashed once or twice, then was extinguished. And now I saw Wilks plainly, standing in the Earthlight, gazing down.

Queer actions! Had the Earthlight touched him? Or was that a local signal-call which he had sent out? Why should Wilks be signalling? What was he doing with a hand-helio? Our watchmen, I knew, had no reason to carry one.

And to whom could Wilks be signalling across this Lunar desolation? The answer stabbed at me: to Miko's band!

I waited another moment. No further light. Wilks was still up there!

I WENT back to the lock entrance. Spare suits and helmets were here beside the keeper. He gazed at me inquiringly.

"I'm going out, Franck, just for a minute." It struck me that perhaps I was a meddlesome fool. Wilks, of all Grantline's men, was, I knew, most in his commander's trust. The signal could have been some part of this night's ordinary routine, for all I knew.

I was hastily donning an Erentz suit. I added, "Let me out. I just got the idea Wilks is acting queerly." I laughed. "Maybe the Earthlight has touched him."

With my helmet on I went through the locks. Once outside, with the outer panel closed behind me, I dropped the weights from my belt and shoes and extinguished my helmet-light.

Wilks was still up there. Apparently he had not moved. I bounded off across the ledge to the foot of the ascending stairs. Did Wilks see me coming? I could not tell. As I approached the stairs the platform was cut off from my line of vision.

I mounted with bounding leaps. In my flexible gloved hand I carried my only weapon, a small bullet projector with oxygen firing caps for use in this outside near-vacuum. The leaden bullet with its slight mass would nevertheless pierce a man at the distance of twenty feet.

I held the weapon behind me. I would talk to Wilks first.

I went slowly up the last hundred feet. Was Wilks still up there? The summit was bathed in Earthlight. The little metal observatory platform came into view above my head.

Wilks was not there. Then I saw him standing on the rocks nearby, motionless. But in a moment he saw me coming.

I waved my left arm with a gesture of greeting. It seemed to me that he started, made as though to leap away, then changed his mind and waited for me.

I sailed from the head of the staircase with a twenty-foot leap and landed lightly beside him. I gripped his arm for audiphone contact.

"Wilks!"

Through the visors his face was visible. I saw him, and he saw me. And I heard his voice.

"You, Haljan! How nice!"

It was not Wilks, but the brigand Coniston!

CHAPTER XXIV
Imprisoned!

THE duty-man at the exit locks of the main building stood at his window and watched me curiously. He saw me go up the spider-stairs. He could see the figure he thought was Wilks, standing at the top. He saw me join Wilks, saw us locked together in combat.

For an instant the duty-man stood amazed. There were two fantastic, misshapen figures swaying in the Earthlight five hundred feet above the camp, fighting desperately at the very brink. They were small, dwarfed by distance, alternately dim and bright as they swayed in and out of the shadows. Soon the duty-man could not tell one from the other. Haljan and Wilks—fighting to the death!

The duty-man recovered himself and sprang into action. An interior siren-call was on the instrument panel near him. He rang it, alarming the camp.

The men came rushing to him, Grantline among them.

"What's this? Good God, Franck!"

They saw the silent, deadly combat up there on the cliff. The two figures had fallen together from the observatory platform, dropped twenty feet to a lower landing on the stairs. They lay as though stunned for a moment, then fought on.

Grantline stood stricken with amazement. "That's Wilks!"

"And Haljan," the duty-man gasped. "Went out—something wrong with Wilks—acting strangely—"

The interior of the camp was in a turmoil. The men awakened from sleep, ran out into the corridors, shouted questions.

"An attack?"

"Is it an attack?"

"The brigands?"

BUT it was Wilks and Haljan in a fight out there on the cliff. The men crowded at the bulls'-eye windows.

And over all the confusion the alarm siren, with no one thinking to shut it off, was screaming with its electrical voice.

Grantline, stricken for that moment of inactivity, stood gazing. One of the figures broke away from the other, bounded up to the summit from the stair-platform to which they had fallen. The other followed. They locked together, swaying at the brink. For an instant it seemed to Grantline that they would go over; then they surged back, momentarily out of sight.

Grantline found his wits. "Stop them! I'll go out to stop them! What fools!"

He was hastily donning one of the Erentz suits which stood at the lock entrance. "Shut off that siren, Franck!"

Within a minute Grantline was ready. The duty-man called from the window:

"Still at it! By the infernal, such fools! They'll kill themselves!"

The figures had swayed back into view, then out of sight again.

"Franck, let me out."

Grantline was ready. He stood, helmet in hand.

"I'll go with you, Commander."

But the volunteer was not equipped. Grantline would not wait.

"I'm going at once. Hurry, Franck."

The duty-man turned to his panel. The volunteer shoved a weapon at Grantline. "Here, take this."

Grantline jammed on his helmet.

HE moved the few steps into the small air-chamber which was the first of the three pressure locks. Its interior door-panel swung open for him. But the door did not close after him!

Cursing the duty-man's slowness, he waited a few seconds. Then he turned to the corridor. The duty-man came running.

Grantline took off his helmet. "What in hell—"

"Broken! Dead!"

"What!"

"Smashed from outside," gasped the duty-man. "Look there—my tubes—"

The control-tubes of the portes had flashed into a close-circuit and burned out. The admission portes would not open!

"And the pressure controls smashed! Broken from outside—!"

There was no way now of getting out through these pressure-locks. The doors, the entire pressure-lock system, was dead. Had it been tampered with from outside?

As though to answer Grantline's amazed question there came a chorus of shouts from the men at the corridor windows.

"Commander! By God—look!"

A figure was outside, close to the building! Clothed in suit and helmet, it stood, bloated and gigantic. It had evidently been lurking at the porte-entrance, had ripped out the wires there.

It moved past the windows, saw the staring faces of the men, and made off with giant bounds. Grantline reached the window in time to see it vanish around the building corner.

It was a giant figure, larger than a normal Earthman. A Martian?

UP on the summit of the crater the two small figures were still fighting. All this turmoil had taken no more than a minute or two.

A lurking Martian outside? The brigand, Miko? More than ever, Grantline was determined to get out. He shouted to his men to don some of the other suits, and called for some of the hand bullet projectors.

But he could not get out through these main admission portes. He could have forced the panels open perhaps; but with the pressure-changing mechanisms broken, it would merely let the air out of the corridor. A rush of air, probably uncontrollable. How serious the damage was no one could tell as yet. It would perhaps take hours to repair it.

Grantline was shouting. "Get those weapons! That's a Martian outside! The brigand leader, probably! Get into your suits, anyone who wants to go with me! We'll go by the manual emergency exit!"

But the prowling Martian had found it! Within a minute Grantline was there. It was a smaller, two-lock gateway of manual control, so that the person going out could operate it himself. It was in a corridor at the other end of the main building. But Grantline was too late! The lever would not open the panels!

Had someone gone out this way and broken the mechanisms after him? A traitor in the camp? Or had someone come in from outside? Or had the skulking Martian outside broken this lock as he had broken the other?

The questions surged on Grantline. His men crowded around him. The news spread. The camp was a prison. No one could get out.

And outside, the skulking Martian had disappeared. But Wilks and Haljan were still fighting. Grantline could see the two figures up on the observatory platform. They bounded apart, then together again. Crazily swaying—bouncing—striking the rail.

THEY went together in a great leap off the platform onto the rocks, and rolled in a bright patch of Earthlight. First one on top, then the other, they rolled, unheeding, to the brink. Here, beyond the midway ledge which held the camp, it was a sheer drop of a thousand feet, on down to the crater-floor.

The figures were rolling: then one shook himself loose, rose up, seized the other and, with a desperate lunge, shoved him—

The victorious figure drew back to safety. The other fell, hurtling down into the shadows past the camp-level—down out of sight in the darkness of the crater-floor.

Snap, who was in the group near Grantline at the windows, gasped.

"God! Was that Gregg Haljan who fell?"

No one could say. No one answered. Outside, on the camp-ledge, another helmeted figure now became visible. It was not far from the main building when Grantline first noticed it. It was running fast, bounding toward the spider-staircase. It began mounting.

And now still another figure became visible—the giant Martian again. He appeared from around the corner of the main Grantline building. He evidently saw the winner of the combat on the cliff, who now was standing in the Earthlight, gazing down. And he saw, too, no doubt, the second figure mounting the stairs. He stood quite near the window through which Grantline and his men were gazing, with his back to the building, looking up to the summit. Then he ran with tremendous leaps toward the ascending staircase.

Was it Haljan standing up there on the summit? Who was it climbing the staircase? And was the third figure Miko?

Grantline's mind framed the questions. But his attention was torn from them, and torn even from the swift silent drama outside. The corridor was ringing with shouts.

"We're imprisoned! Can't get out! Was Haljan killed? The brigands are outside!"

And then an interior audiphone blared a call for Grantline. Someone in the instrument room of the adjoining building was talking:

"Commander, I tried the telescope to see who got killed—"

But he did not say who got killed, for he had greater news.

"Commander! The brigand ship!"

Miko's reinforcements from Mars had come.

CHAPTER XXV
The Combat on the Crater-top

NOT Wilks, but Coniston! His drawling, British voice:

"You, Gregg Haljan! How nice!"

His voice broke off as he jerked his arm from me. My hand with the bullet-protector came up, but with a sweeping blow he struck my wrist. The weapon dropped to the rocks.

I fought instinctively, those first moments; my mind was whirling with the shock of surprise. This was not Wilks, but the brigand Coniston.

His blow wrenched him around. Awkward, fighting in the air-puffed suits, with only a body-weight of some thirty pounds! Coniston stumbled over the rocks. I had still scarce recovered my wits, but I avoided his outflung arms, and, stooping, tried to recover my revolver. It lay nearby. But Coniston followed my scrambling steps and fell upon me. My foot struck the weapon; it slid away and fell down a crag into a six-foot pit.

We locked together, and when I rose erect he had me around the middle. His voice jangled with broken syllables in my receiver.

"Do for you now, Haljan—"

It was an eery combat. We swayed, shoving, kicking, wrestling. His hold around my middle shut off the Erentz circulation; the warning buzz rang in my ears to mingle with the rasp of his curses. I flung him off, and my tiny Erentz motors recovered. He staggered away, but in a great leap came at me again.

I was taller, heavier and far stronger than Coniston. But I found him crafty, and where I was awkward in handling my lightness, he seemed more skilfully agile.

I BECAME aware that we were on the twenty-foot square grid of the observatory platform. It had a low metal railing. We surged against it. I caught a dizzying glimpse of the abyss. Then it receded as we bounced the other way. And then we fell to the grid. His helmet bashed against mine, striking as though butting with the side of his head to puncture my visor-panel. His gloved fingers were trying to rip at the fabric around my throat.

As we regained our feet, I flung him off, and bounded, like a diver, head-first into him. He went backward, but skilfully kept his feet, gripped me again and shoved me.

I was tottering at the head of the staircase—falling. But I clutched at him.

We fell some twenty or thirty feet to the next lower spider landing. The impact must have dazed us both. I recall my vague idea that we had fallen down the cliff—my Erentz motors smashed—my air shut off. Then the air came again. The roaring in my ears was stilled; my head cleared, and I found that we were on the landing—fighting.

He presently broke away from me, bounded to the summit, with me after him. In the close confines of the suit I was bathed in sweat, and gasping. I had had no thought to increase the oxygen content of my air. But I sorely needed more oxygen for my laboring, pounding heart and my panting breath. I fumbled for the oxygen control-lever. I could not find it; or it would not operate.

I realized I was fighting sluggishly, almost aimlessly. But so was Coniston!

IT seemed dreamlike. A phantasmagoria of blows and staggering steps. A nightmare with only the horrible vision of this goggled helmet always before my eyes.

It seemed that we were rolling on the ground, back on the summit. The unshadowed Earthlight was clear and bright. The abyss was beside me. Coniston, rolling, was now on top, now under me, trying to shove me over the brink. It was all like a dream—as though I were asleep, dreaming that I did not have enough air.

I strove to keep my senses. He was struggling to roll me over the brink. Ah, that would not do! But I was so tired. One cannot fight without oxygen!

I suddenly knew that I had shaken him off and gained my feet. He rose up, swaying. He was as tired, confused, half-asphyxiated as I.

The brink of the abyss was behind us. I lunged, desperately shoving, avoiding his clutch.

He went over, and fell soundlessly, his body whirling end over end down into the shadows, far down.

I drew back. My senses faded as I sank panting to the rocks. But with inactivity, my thumping heart quieted. My respirations slowed. The Erentz circulation gained on my poisoned air. It purified.

That blessed oxygen! My head cleared again. Strength came to me. I felt better.

Coniston had fallen to his death. I was victor. I went to the brink, cautiously, for I was still dizzy. I could see, far down there on the crater-floor, a little patch of Earthlight in which a mashed human figure was lying.

I STAGGERED back again. A moment or two must have passed while I stood there on the summit, with my senses clearing and my strength renewed as the blood-stream cleared in my veins.

I was victor. Coniston was dead. I saw now, down on the lower staircase below the camp-ledge, another goggled figure lying huddled. That was Wilks, no doubt. Coniston had doubtless caught him there, surprised him, killed him.

My attention, as I stood gazing, went down to the camp-buildings. Another figure was outside! It bounded along the ledge, reached the foot of the ascending staircase at the top of which I was standing. With agile leaps, it came mounting at me!

Another brigand! Miko? No, it was not large enough to be Miko, not nearly large enough. I was still confused. I thought of Hahn. But that was absurd. Hahn was in the wreck of the Planetara. One of the stewards then....

The figure came up the staircase recklessly, to assail me. I took a step backward, bracing myself to receive this new antagonist.

And then I saw Miko! Unquestionably he: for there was no mistaking his giant figure. He was down on the camp-ledge, running toward the foot of the staircase, coming up to help this other man in advance of him.

I thought of my revolver. I turned to try and find it. I was aware that the first of my assailants was at the stairhead. I could not locate at once where the revolver had fallen. I would be caught, leaped upon from behind. Should I run?

I swung back to see what the oncoming brigand was doing. He had reached the summit. His arms went up, legs bent under him. With a sailing leap he launched for me. I could have bounded way, but with a last look to locate the revolver, I braced myself for the shock.

The figure hit me. It was small and light in my clutching arms. I recall I saw that Miko was half-way up the staircase. I gripped my assailant. The audiphone contact brought a voice.

"Gregg! Is it you?"

It was Anita clutching at me!

CHAPTER XXVI
At Bay

GREGG, you're safe!"

She had heard the camp corridors resounding with the shouts that Wilks and Haljan were fighting. She had come upon a suit and helmet by the manual emergency lock, had run out through the lock, confused, with her only idea to stop Wilks and me from fighting. Then she had seen one of us killed. Impulsive, barely knowing what she was doing, she mounted the stairs, frantic to find if I were alive.

"Anita!"

Miko was coming! She had not seen him: for she had no thought of brigands—only the belief that either Wilks or I had been killed.

But now, as for an instant we stood together on the rocks near the observation platform, I could see the towering figure of Miko nearing the top of the stairs.

"Anita, that's Miko! We must run."

Then I saw my bullet projector. It lay in a bowl-like depression quite near us. I jumped for it. And as I tore loose from Anita, she leaped down after me. It was a broken bowl in the rocks, some six feet deep. It was open on the side facing the staircase—a narrow, ravinelike gully, full of gray, broken, tumbled rock-masses. The little gully was littered with crags and boulders. But I could see out through it.

Miko had come to the head of the staircase. He stopped there, his great figure etched sharply by the Earthlight. I think he must have known that Coniston was the one who had fallen over the cliff, as my helmet and Coniston's were different enough for him to recognize which was which. He did not know who I was, but he did know me for an enemy.

HE stood now at the summit, peering to see where we had gone. He was no more than fifty feet from us.

"Anita, lie down."

I pulled her down on the rocks. I took aim with the bullet projector. But I had forgotten our helmet-lights. Miko must have seen them just as I pulled the trigger. The flying bullet missed him as he jumped sidewise. He dropped, but I could see him moving in the shadows to where a jutting rock gave him shelter. I fired again.

"Gregg."

I had stood up to take aim. I saw the bullet chip a bit of rock. Anita pulled me sharply down beside her.

"Gregg, he's armed!"

It was his turn to fire. It came—the familiar vague flash of the paralyzing ray. It spat its tint of color on the rocks near us, but could not reach us.

Miko rose a moment later and bounded to another rock. I scrambled up, and shot at him, but missed. Then he crouched and returned my fire from his new angle; but Anita and I had shifted.

Time passed—only a few moments. I could not see Miko momentarily. Perhaps he was crouching; perhaps he had moved away again. He was, or had been, on slightly higher ground than the bottom of our bowl. It was dim down here where we were lying, but I feared that every moment Miko might appear and strike at us. His ray at any short range would penetrate our visor-panes, even though our suits might temporarily resist it.

"Anita—it's too dangerous here."

Had I been alone, I might perhaps have leaped up to lure Miko. But with Anita I did not dare chance it.

"We've got to get back to the camp," I told her. The audiphone brought her comment:

"Perhaps he has gone."

BUT he had not. We saw him again, out in a distant patch of Earthlight. He was further from us than before, but on still higher ground. We had extinguished our small helmet-lights. But he knew we were here, and possibly he could see us. His projector flashed again. But we had again shifted, and were untouched. He was a hundred feet or more away now. His weapon was of longer range than mine. I did not answer his fire, for I could not hope to hit him at such a distance, and the flash of my weapon would help him with his aim.

I murmured to Anita, "We must get out of here."

Yet how did I dare take Anita from these concealing shadows? Miko could reach us so easily as we bounded away, in plain view in the Earthlight of the open summit! We were caught, at bay in this little bowl.

The camp from here was not visible. But out through the broken gully, beyond the staircase top, a white beam of light suddenly came up from below.

"Haljan."

It spelled the signal.

"Haljan."

It was coming from the Grantline instrument room, I knew.

I could answer it with my helmet-light, but I did not dare. I hesitated.

"Try it," urged Anita.

WE crouched where we thought we might be safe from Miko's fire. My little light-beam shot up from the bowl. It was undoubtedly visible to the camp.

"Yes? I am Haljan."

And I added:

"Help! Send us help."

I did not mention Anita. Miko could doubtless read these signals. And in the camp they must have missed Anita by now. They answered:

"Cannot—"

I lost the rest of it. There came a flash from Miko's weapon. But it gave us confidence. He could not reach us at the moment.

The Grantline beam repeated:

"Cannot come out. Portes broken. You cannot get in. Stay where you are—an hour or two. We may be able to repair portes."

The portes were broken! Stay here an hour or two! But I could not hold this position against Miko that long! Sooner or later he would find a place from where he could sweep this bowl beyond possibility of our hiding. I saw him running now, well beyond my range, to ferret out another point of vantage.

I extinguished my light. What use was it to tell Grantline anything further? Besides, my light was dangerous.

But the Grantline beam spelled another message:

"The brigand ship is coming! It will be here before we can get out to you! No lights! We will try and hide our location."

And the signal-beam brought a last appeal to me:

"Miko and his men will divulge where we are. Unless you can stop them—"

The beam vanished. The lights of the Grantline camp made a faint glow that showed above the crater-edge. The glow died, as the camp now was plunged into darkness.

CHAPTER XXVII
Anita's Plan

WE crouched in the shadows, the Earthlight filtering down to us. The skulking figure of Miko had vanished; but he was out there somewhere on the crags I was sure, lurking, maneuvering to where he could strike us with his ray. Anita's metal-gloved hand was on my arm; in my ear diaphragm her voice sounded eager and unmistakable:

"What was the signal, Gregg?"

She could not read the semaphore lights. I told her.

"Oh Gregg, the Martian ship coming!"

Her mind clung to that as the most important thing. But not so myself. To me there was only the realization that Anita was caught out here, almost at the mercy of Miko's ray. Grantline's men could not get out to help us, nor could I get Anita into the camp.

She added, "Where do you suppose the ship is? In telescopic view?"

"Yes—twenty or thirty thousand miles up, probably."

The stars and the Earth were visible over us. Somewhere up there disclosed by Grantline's instrument but not yet discernible to the naked eye, Miko's reinforcements were hovering.

I stood up cautiously to try and locate Miko. Immediately I saw him. He jumped as though fearing my coming bullet, and I dropped back, barely avoiding his flash, which swept across the top of our bowl.

"Gregg—Gregg, don't take such a chance!"

We lay for a moment in silence. It was horribly nerve-straining. Miko could be creeping up on us. Would he dare chance my sudden fire? Creeping—or would he make a swift, unexpected rush?

The feeling that he was upon us abruptly swept me. I jumped to my feet, against Anita's effort to hold me. But again Miko had vanished. Where was he now?

I SANK back. "That ship will be here in a few hours."

I told her what Grantline's signal had suggested: the ship was hovering overhead. It must be fairly close; for Grantline's telescope had revealed its identity as a bandit flyer, unmarked by any of the standard code-identification lights. It was doubtless too far away as yet to have located the whereabouts of Grantline's camp. The Martian brigands knew that we were in the vicinity of Archimedes, but no more than that. Searching this glowing Moon surface, our little lights, the tiny local semaphore beams we had momentarily been using, could easily pass unnoticed.

But as the brigand ship approached now—dropping close to Archimedes as it probably would—our danger was that Miko and his men would then signal it, join it, and reveal the camp's location, and the brigand attack would be upon us.

I told this now to Anita. "The signal said, 'Unless you can stop them.'"

It was an appeal to me. But how could I respond to it? What could I do, alone out here with Anita, to cope with this enemy?

Anita made no comment.

I added, "That ship will land near Archimedes I imagine, within an hour or two! If Grantline can repair his portes, and I can get you inside—"

Again she made no comment. Then suddenly she gripped me. "Gregg, look there!"

Out through the gully break in our bowl the figure of Miko showed! He was running. But not at us. Circling the summit, leaping to keep himself behind the upstanding crags. He passed the head of the staircase; he did not descend it, but headed off along the summit of the curving crater-rim.

I STOOD up to watch him. He was making off. Abandoning us!

"He's going!"

I let her stand up beside me; cautiously, at first, for it occurred to me that this might be a ruse to cover some other of Miko's men who might be lurking up here.

But the summit seemed clear. The figure of Miko was a thousand feet away now. We could see the tiny blob of it bobbing over the rocks. Then it plunged down—not into the crater-valley, but out toward the open Moon surface.

Miko had abandoned his attack on us. The reason seemed plain. He had come here from his encampment with Coniston, had sent Coniston ahead to lure and kill Wilks. When this was done, Coniston had flashed his brief signal to Miko, who was hiding nearby.

It was not like the brigand leader to remain in the background. Miko was no coward. But Coniston could impersonate Wilks, whereas Miko's giant stature at once would reveal his identity. Miko had been engaged in smashing the portes. He had looked up and seen me kill Coniston. He had come up to assail me. And then he had read Grantline's signal to me. It was his first knowledge that his ship was at hand. With the camp exits inoperative, Grantline and his men were imprisoned. Miko made an effort to kill me. He did not know my companion was Anita. The effort was taking too long: with the Grantline camp imprisoned and his ship at hand, it was Miko's best move to return to his own camp, rejoin his men, and await their opportunity to signal the ship.

At least, so I reasoned it. Anita and I stood alone. What could we do?

WE went to the brink of the cliff. The unlighted Grantline buildings showed vaguely in the Earthlight.

I said, "We'll go down, I'll leave you there. You can wait at the porte. They'll repair it soon, perhaps, and let you in."

"And what will you do?" she demanded.

I was hurrying her down the stairs. But suddenly she stopped. "What are you going to do, Gregg?"

I had not intended to tell her. "Hurry, Anita!"

"Why?" She stood stock still. Through the visors I could see her white face gazing at me rebelliously.

"Why should I hurry, Gregg?"

"Because I want to leave you at the porte. I'm going after Miko—try and locate where he and his men are camping."

I had indeed no specific plan as yet. But it seemed useless for me to sit at the porte waiting to be let in.

"But he's gone, Gregg."

She was right on that. Miko was already a mile or more away, down on the outer surface, making off. He would soon be out of sight. It would be impossible to follow him.

"Gregg, let me go with you."

She jerked away from me and bounded back up the staircase. I caught her on the summit.

"Anita!"

"I'm going with you."

"You're going to stay here."

"I'm not!"

This exasperating controversy! And time was so precious!

"Anita, please."

"I'll be safer with you than waiting here, Gregg."

IT almost decided me. Perhaps she would. It was only my intention to follow Miko at a distance. And with much more of this delay here, he would be lost to me.

And she added, "Besides, I won't stay, and you can't make me."

We ran along the crater-top. At its distant edge the lower plain spread before us. Far down, and far away on the distant broken surface, the leaping figure of Miko showed.

We plunged down the broken outer slope, reached the level. Soon, as we ran, the little Grantline crater faded behind us.

Anita ran more skillfully than I. Ten minutes or so passed. We had seen Miko, and the direction he was taking, but down here on the plain we could no longer see him. It struck me that this was purposeless—and dangerous. Suppose Miko were to see us following? Suppose he stopped and lay in ambush to fire at us as we came leaping heedlessly by?

"Anita, wait," I said, checking her.

I drew her down amid a group of tumbled boulders. And then abruptly she clung to me.

"Gregg, I know what we can do! Gregg, don't tell me you won't let me try it!"

I LISTENED to her plan. Incredible! Incredibly dangerous! Yet, as I pondered it, the very daring of the thing seemed the measure of its possible success. The brigands would never imagine we could be so rash!

"But Anita—"

"Gregg, you're stupid!" It was her turn to be exasperated. In truth, I was indeed in no mood for daring, for my mind was obsessed with Anita's safety. I had been planning that we might see the glow of Miko's encampment, and then return to Grantline and hope that he would have the portes repaired.

"But Gregg—the safety of the treasure—of all the Grantline men...."

"To the infernal with that! It's you—your safety."

"My safety, then! If you put me in the camp and the brigands attack it and I am killed—what then? But this plan of mine, if we can do it, Gregg ... safety, in the end, for all of us."

And it seemed possible. We crouched, discussing it. So daring a thing!

The brigand ship would come down near Archimedes. That was fifty miles from Grantline. The brigands from Mars would not have seen the dark Grantline buildings hidden in the little crater-pit. They would wait for Miko and his men to make their whereabouts known.

MIKO'S encampment was ahead of us now, undoubtedly. We had been following him toward the Mare Imbrium; we were at its borders now. Archimedes from here was also about fifty miles.

And Anita proposed that we go to Archimedes, climb in slope and await the coming of the brigand ship. Miko would be off in the Mare Imbrium. Or at least, we hoped so. He would signal his ship. But Anita and I, closer to it, would also signal it—and, posing as brigands, could join it!

"Remember, Gregg, I am Anita Prince, George's sister." Her voice trembled as, she mentioned her dead brother. "They know that George was in Miko's pay, and I am his sister.... It will help convince them."

This daring scheme! If we could join the ship, we might be able to persuade its leader that Miko's distant signals were merely a ruse of Grantline to lure the brigands in that direction. A long-range projector from the ship would kill Miko and his men as they came forward to join it! And then we could falsely direct the brigands, lead them away from Grantline and the treasure.

"Gregg, we must try it."

Heaven help me, I yielded to her persuasion!

We turned at right angles and ran toward where the distant frowning walls of Archimedes loomed against the starlit sky.

CHAPTER XXVIII
The Ascent of Archimedes

THE broken shaggy ramparts of the giant crater rose above us. We toiled upward, out of the foothills, clinging now to the crags and pitted terraces of the main ascent. An hour had passed since we turned from the borders of the Mare Imbrium. Or was it two hours? I could not tell. I only know that we ran with desperate frantic haste.

Anita would not admit that she was tired. She was more skilful than I in this leaping over the broken rock masses. Yet I felt that her slight strength must give out. It seemed miles up the undulating slopes of the foothills with the black and white ramparts of the massive crater close before us.

And then the main ascent. There were places where, like smooth black frozen ice, the walls rose sheer. We avoided them, toiling aside, plunging into gullies, crossing pits where sometimes we perforce went downwards, and then up again; or sometimes we stood, hot and breathless, upon ledges, recovering our strength, selecting the best route upward.

This tumbled mass of rock! Honeycombed everywhere with caves and passages leading into darkness impenetrable. There were pits into which we might so easily have fallen; ravines to span, sometimes with a leap, sometimes by a long and arduous detour.

Endless climb! We came to a ledge, with the plains of the Mare Imbrium stretching out beneath us. We might have been upon this main ascent for an hour; the plains were far down, the broken surface down there smoothed now by the perspective of our height. And yet still above us the brooding circular wall went up into the sky. Ten thousand feet still above us—I think it was at least that, or more.

"You're tired, Anita. We'd better stay here."

"No! If we could only get to the top—the ship may land on the other side—they would see us if we were at the top."

THERE was as yet no sign of the brigand ship. With every stop for rest we searched the starry vault. The Earth hung over us, flattened beyond the full. The stars blazed to mingle with the Earthlight and illumine these massive crags of the Archimedes walls. But no speck appeared to tell us that the ship was up there.

We were on the curving side of the Archimedes wall which fronted the Mare Imbrium to the North. The plains lay like a great frozen sea, congealed ripples shining in the light of the Earth, with dark patches to mark the hollows. Somewhere down there—six or eight thousand feet below us now, or even more than that, for all I could tell—Miko's encampment lay concealed. We searched for lights of it, but could see none.

Or had Miko rejoined his party, left his camp and come here like ourselves to climb Archimedes? Or was our assumption wholly wrong—perhaps the brigand ship would not land near here at all?

Sweeping around from the Mare Imbrium, the plains were less smooth—the shattered, crag-littered, crater-scarred region beyond which the distant Apennines raised their terraced walls. The little crater which concealed the Grantline camp was off that way. There was nothing to mark it from here.

"Gregg, do you see anything up there? There seems to be a blur."

HER sight, sharper than mine, had picked it out. The descending brigand ship! A faintest tiny blur against the stars, a few of them occulted as though strangely an invisible shadow were upon them. A growing shadow, materializing into a blur—a blob, a shape faintly defined. Then sharper until we were sure of what we saw. It was the brigand ship. It came dropping slowly, silently down.

We crouched on the little ledge. A cave-mouth was behind us. A gully was beside us, a break in the ledge; and at our feet the wall dropped sheer.

We had extinguished our little lights. We crouched, silently gazing up into the stars.

The ship, when first we distinguished it was central over Archimedes. We thought for a while that it might descend into the crater. But it did not; it came sailing forward.

I whispered into the audiphone—whispering by instinct, as though out here in all this airless desolation someone might overhear us!

"It's coming over the crater."

Her hand pressed my arm in answer.

I recalled that when, from the Planetara, Miko had forced Snap to signal this brigand band on Mars, Miko's only information as to the whereabouts of the Grantline camp was that it lay between Archimedes and the Apennines. That was Grantline's first message to us, and Miko had relayed it to his men. The brigands from Mars now were following that information.

A tense interval passed. We could see the ship plainly above us now, a gray-black shape among the stars up beyond the shaggy, towering crater-rim. The vessel came upon a level keel, hull-down, slowly circling, looking for Miko's signal, no doubt, or for possible lights of Grantline. They were also picking a landing place.

WE saw it soon as a cylindrical, cigarlike shape, rather smaller than the Planetara, but similar of design. It bore lights now. The ports of its hull were tiny rows of illumination, and the glow of light under its rounding upper dome was faintly visible.

A bandit ship, no doubt of that. Its identification keel-plate was empty of official pass-code lights. These brigands had not attempted to secure official sailing lights when leaving Ferrok-Shahn. It was an outlawed ship, unmistakably. And here upon the deserted Moon there was no need for secrecy. Its lights were openly displayed, that Miko might see it and join it.

It went slowly past us, only a few thousand feet higher than our level. We could see the whole outline of its pointed cylinder-hull, with the rounded dome on top. And under the dome was its open deck-space, with a little cabin superstructure in the center.

I thought for a moment that by some fortunate chance it might land quite near us. There was a wide ledge a quarter of a mile away.

"Anita, look."

But it went past. And then I saw that it was heading for a level, plateau-like surface a few miles further on. It dropped, cautiously floating down.

There was still no sign of Miko. But I realized that haste was necessary. We must be the first to join the brigand ship.

I lifted Anita to her feet. "I don't think we should signal from here."

"No. Miko might see it."

We could not tell where he was. Down on the plains, perhaps? Or up here, somewhere in these miles of towering rocks?

"Are you ready, Anita?"

"Yes, Gregg."

I STARED through the visors at her white, solemn face.

"Yes, I'm ready," she repeated.

Her hand-pressure seemed to me suddenly like a farewell. Were we plunging rashly into what was destined to mean our death? Was this a farewell?

An instinct swept me not to do this thing. Why, in an hour or two I could have Anita back to the comparative safety of the Grantline buildings. The exit portes would doubtless be repaired by now. I could get her inside.

She had bounded away from me, leaped down some thirty feet into the broken gully, to cross it and then up on the other side. I stood for an instant watching her fantastic shape, with the great rounded, goggled, trunked helmet and the lump on her shoulders which held the little Erentz motors. Then I made after her.

It did not take us long—two or three miles of circling along the giant wall. The ship lay only a few hundred feet above our level.

We stood at last on a buttelike pinnacle. The hull-porte lights of the ship were close over us. And there were moving lights up there, tiny moving spots on the adjacent rocks. The brigands had come out, prowling around to investigate their location.

No signal yet from Miko. But it might come at any moment.

"I'll flash now," I whispered.

"Yes."

The brigands had probably not yet seen us. I took the lamp from my helmet. My hand was trembling. Suppose my signal were answered by a shot? A flash from some giant projector mounted on the ship?

Anita crouched behind a rock, as she had promised. I stood with my torch, and flung its switch.

My puny light-beam shot up. I waved it, touched the ship with its faint glowing circle of illumination.

They saw me. There was a sudden movement among the lights up there.

I SEMAPHORED:

"I am from Miko. Do not fire."

I used the open Universal Code. In Martian first, and then in English.

There was no answer, but no attack. I tried again.

"This is Haljan, once of the Planetara. George Prince's sister is with me. There has been disaster to Miko."

A small light-beam came down from the brink of the overhead cliff beside the ship.

"We read you."

I went steadily on: "Disaster—the Planetara is wrecked. All killed but me and George Prince's sister. We want to join you."

I flashed off my light. The answer came: "Where is the Grantline camp?"

"Near here. The Mare Imbrium."

As though to answer my lie, from down on the Earthlit plains, ten miles or so from the crater-base, a tiny signal-light shot up. Anita saw it and gripped me.

"There is Miko's light!"

It spelled in Martian, "Come down. Land Mare Imbrium."

Miko had seen the signalling up here and was joining it! He repeated, "Land Mare Imbrium."

I FLASHED a protest up to the ship: "Beware! That is Grantline! Trickery!"

From the ship the summons came: "Come up."

We had won this first encounter! Miko must have realized his disadvantage. His distant light went out.

"Come, Anita."

There was no retreat now. But again I seemed to feel in the pressure of her hand that vague farewell.

Her voice whispered, "We must do our best, act our best to be convincing."

In the white glow of a search-beam we climbed the crags, reached the broad upper ledge. Helmeted figures rushed at us, searched us for weapons, seized our helmet lights. The evil face of a giant Martian peered at me through the visors. Two other monstrous, towering figures seized Anita.

We were shoved toward the port-locks at the base of the ship's hull. Above the hull bulge I could see the grids of projectors mounted in the dome-side, and the figures of men standing on the deck, peering down at us.

We went through the admission locks into a hull corridor, up an incline passage, and reached the lighted deck. Our helmets were taken off. The Martian brigands crowded around us.

CHAPTER XXIX
On the Brigand Ship

ANITA'S words echoed in my memory: "We must act our best to be convincing." It was not her ability that I doubted as much as my own. She had played the part of George Prince cleverly, unmasked only by an evil chance.

I steeled myself to face the searching glances of the brigands as they shoved around us. This was a desperate game into which we had plunged! For all our acting, how easy it would be for some small chance thing abruptly to undo us! I realized it, and now, as I gazed into the peering faces of these men from Mars, I cursed my witless rashness which had brought Anita into this!

The brigands—some ten or fifteen of them here on the deck—stood in a ring around us. They were all big men, nearly of a seven-foot average, dressed in leather jerkins and short leather breeches, with bare knees and flaring leatherboots. Piratical swaggering fellows, knife-blades mingled with small hand-projectors fastened to their belts. Gray, heavy faces, some with scraggling, unshaved beard. They plucked at us, jabbering in Martian.

One of them seemed the leader. I said sharply, "Are you the commander here? I speak not Ilton⁴ well. You speak the Earth English?"

4: Ilton, the ruling race and official language of the Martian Union.

"Yes," he said readily, "I am Commander here." He spoke English with the same freedom and accent of Miko. "Is this George Prince's sister?"

"Yes. Her name is Anita Prince. Tell your men to take their hands off her."

He waved his men away. They all seemed more interested in Anita than in me. He added:

"I am Set Potan." He addressed Anita. "George Prince's sister? You are called Anita? I have heard of you. I knew your brother—indeed, you look very much like him."

He swept his plumed hat to the grid with a swaggering gesture of homage. A courtierlike fellow this, debonair as a Venus cavalier!

He accepted us. I realized that Anita's presence was immensely valuable in making us convincing. Yet there was about this Potan—as with Miko—a disturbing suggestion of irony. I could not make him out. I decided that we had fooled him. Then I remarked the steely glitter of his eyes as he turned to me.

"You were an officer of the Planetara?"

THE insignia of my rank was visible on my white jacket-collar which showed beneath the Erentz suit, now that my helmet was off.

"Yes, I was supposed to be. But a year ago I embarked upon this adventure with Miko."

He was leading us to his cabin. "The Planetara wrecked? Miko dead?"

"And Hahn and Coniston. George Prince, too—we are the only survivors."

While we divested ourselves of our Erentz suits at his command, I told him briefly of the Planetara's fall. All had been killed on board save Anita and me. We had escaped, awaited his coming. The treasure was here; we had located the Grantline camp, and were ready to lead him to it.

Did he believe me? He listened quietly. He seemed not shocked at the death of his comrades. Nor yet pleased: merely imperturbable.

I added with a sly, sidelong glance, "There were too many of us on the Planetara. The purser had joined us, and many of the crew. And there was Miko's sister, the Setta Moa—too many. The treasure divides better among less."

An amused smile played on his thin gray lips. But he nodded. The fear which had leaped in me was allayed by his next words.

"True enough, Haljan. He was a domineering fellow, Miko. A third of it all was for him alone. But now...."

The third would go to this sub-leader, Potan! The implication was obvious.

I said, "Before we go any further—I can trust you for my share?"

"Of course."

I FIGURED that my very boldness in bargaining so prematurely would convince him. I insisted, "And Miss Prince? She will have her brother's share?"

Clever Anita! She put in swiftly, "I give no information until you promise! We know the location of the Grantline camp, its weapons, its defense, the amount and location of the ore. I warn you, if you do not play us fair...."

He laughed heartily. He seemed to like us. He spread his huge legs as he lounged in his settle, and drank of the bowl which one of his men set before him.

"Little tigress! Fear me not—I play fair!" He pushed two of the bowls across the table. "Drink, Haljan. All is well with us, and I am glad to hear it. Miss Prince, drink my health as your leader."

I waved it away from Anita. "We need all our wits; your strong Martian drinks are dangerous. Look here, I'll tell you just how the situation stands—"

I plunged into a glib account of our supposed wanderings to find the Grantline camp; its location off in the Mare Imbrium—hidden in a cavern there. Potan, with the drink, and under the gaze of Anita's eyes, was in a high good humor. He laughed when I told him that we had dared to invade the Grantline camp, had smashed its exit portes, had even gotten up to have a look at where the ore was piled.

"Well done, Haljan! You're a fellow to my liking!" But his gaze was on Anita. "You dress like a man, or a charming boy."

She still wore the dark clothes of her brother. She said, "I am used to action—man's garb pleases me. You shall treat me like a man, give me my share of the gold-leaf."

HE had already demanded of us the meaning of that signal from the Mare Imbrium. Miko's signal! It had not come again, though any moment I feared it. I told him that Grantline had doubtless repaired his damaged portes and sallied out to assail me in reprisal. And seeing the brigand ship landing on Archimedes, had tried to lure it.

I wondered if my explanation were very convincing. It did not sound so. But he was flushed now with the drink. And Anita added:

"Grantline knows the territory near his camp very well. He is equipped only for short-range fighting."

I took it up. "It's like this, Potan: if he could get you to land unsuspectingly near the mouth of his cavern...."

I pictured how Grantline might have figured on a sudden surprise attack upon the ship. It was his only chance to catch it unprepared.

We were all three in friendly, intimate mood now. Potan said, "We'll land down there right enough! But I need a few hours for my assembling."

"He will not dare advance," I said. "For one thing, he can't leave the treasure."

"He knows we have unmasked his lure," Anita put in smilingly. "Haljan and I joining you—that silenced him. His light went out very promptly, didn't it?"

She flashed me a side-gaze. Were we acting convincingly? But if Miko started up his signals again, they might so quickly betray us! Anita's thoughts were upon that, for she added:

"Grantline will not dare show his light! If he does, Set Potan, we can blast him with a ray from here! Can't we?"

"Yes," Potan agreed. "If he comes within ten miles, I have one powerful enough. We are assembling it now."

"And we have thirty men?" Anita persisted. "When we sail down to attack him it should not be very difficult to kill all the Grantline party. Thirty of us—that's enough to share in this treasure. I'm glad Miko is dead."

"By Heaven, Haljan, this girl of yours is small, but very blood-thirsty!"

"That accursed Miko murdered her brother," I explained.

ACTING! And never once did we dare relax! If only Miko's signals would hold off and give us time!

We may have talked for half an hour. We were in a small, steel-lined cubby, located in the forward deck-space of the ship. The dome was over it. I could see from where I sat at the table that there was a forward observatory tower under the dome quite near here. The ship was laid out in rather similar fashion to the Planetara, though considerably smaller.

Potan had dismissed his men from his cubby so as to be alone with us. Out on the deck I could see them dragging apparatus about—bringing the mechanisms of giant projectors up from below, beginning to assemble them. Occasionally some of the men would come to our cubby windows to peer in at us curiously.

My mind was roaming as I talked. For all my manner of casualness, I knew that haste was necessary. Whatever Anita and I were to do must be quickly done. But to win this fellow's utter confidence first was necessary, so that we might have the freedom of the ship, might move about unnoticed, unwatched.

I was horribly tense inside. Through the dome windows across the deck from the cubby the rocks of the Lunar landscape were visible. I could see the brink of this ledge upon which the ship lay, the descending crags down the precipitous wall of Archimedes to the Earthlit plains far below. Miko, Moa, and a few of the Planetara's crew were down there somewhere.

ANITA and I had a fairly definite plan. We were now in Potan's confidence. With this interview at an end, I felt that our status among the brigands would be established. We would be free to move about the ship, join in its activities. It ought to be possible to locate the signal-room, get friendly with the operator there.

Perhaps we would find a secret opportunity to flash a signal to Earth. This ship, I was confident, would have the power for a long-range signal, if not of too sustained a length. It was a desperate thing to attempt but our whole procedure was desperate! And I felt—if Anita perhaps could cajole the guard or the duty-man from the signal-room—I might send a single flash or two that would reach the Earth. Just a distress call, signed "Grantline." If I could do that and not get caught.

Anita was engaging Potan in talking of his plans. The brigand leader was boasting of his well-equipped ship, the daring of his men, and questioning her about the size of the treasure. My thoughts were free to roam.

A signal to Earth. And while we were making friends with these brigands, the longest range electronic projector was being assembled. Miko then could flash his signal and be damned to him! I would be on the deck with that projector. Its operator, and I would turn it upon Miko—one flash of it and he and his little band would be wiped out.

But there was our escape to be thought of. We could not remain very long with these brigands. We could tell them that the Grantline camp was on the Mare Imbrium. It would delay them for a time, but our lie would soon be discovered. We must escape from them, get away and back to Grantline. With Miko dead—a distress signal to Earth—and Potan in ignorance of Grantline's location, the treasure would be safe until help arrived from Earth.

It all fitted together so nicely! It seemed possible of success.

Our futile plans! Star-crossed always, doomed, fated always to be upset by such unforeseen evil chances!

"By the infernal, little Anita, you look like a dove, but you're a tigress! A comrade after my own heart—blood-thirsty as a fire-worshipper!"

HER laugh rang out to mingle with his. "Oh no, Set Potan! I am treasure-thirsty."

"We'll get the treasure, never fear, little Anita."

"With you to lead us, Potan, I'm sure we will."

A man entered the cubby. Potan looked frowningly around. "What is it, Argle?"

The fellow answered in Martian, leered at Anita and withdrew.

Potan stood up. I noticed that he was unsteady with the drink.

"They want me with the work at the projectors."

"Go ahead," I said.

He nodded. We were comrades now.

"Amuse yourself, Haljan. Or come out on deck if you wish. I will tell my men you are one of us."

"And tell them to keep their hands off Miss Prince."

He stared at me. "I had not thought of that—a woman among so many men."

His own gaze at Anita was as leeringly offensive as any of his men could have given. He said, "Have no fear, little tigress."

Anita laughed. "I am afraid of nothing."

But when he had lurched from the cabin she touched me. Smiled with her mannish swagger, for fear we were still observed, and murmured:

"Oh, Gregg, I am afraid!"

We stayed in the cubby a few moments, whispering—trying to plan.

"You think the signal room is in the tower, Gregg? This tower outside our window here?"

"Yes, I think so."

"Shall we go out and see?"

"Yes. Keep near me always."

"Oh, Gregg. I will!"

We deposited our Erentz suits carefully in a corner of the cubby. We might need them so suddenly! Then we swaggered out to join the brigands working on the deck.

CHAPTER XXX
Desperate Plans

THE deck glowed lurid in the queer blue-greenish glare of Martian electro-fuse lights. It was in a bustle of ordered activity. Some twenty of the crew were scattered about, working in little groups. Apparatus was being brought up from below to be assembled. There was a pile of Erentz suits and helmets, of Martian pattern, but still very similar to those with which Grantline's expedition was equipped. There were giant projectors of several kinds, some familiar to me, others of a fashion I had never seen before. It seemed there were six or eight of them, still dismantled, with a litter of their attendant batteries and coils and tube-amplifiers. They were to be mounted here on the deck, I surmised; I saw in the dome-side one or two of them already rolled into position at the necessary pressure portes.

Anita and I stood outside Potan's cubby, gazing around us curiously. The men looked at us, but none of them spoke.

"Let's watch from here a moment," I whispered. She nodded, standing with her hand on my arm. I felt that we were very small, here in the midst of these seven-foot Martian men. I was all in white, the costume used in the warm interior of the Grantline camp. Bareheaded, white silk Planetara uniform jacket, broad belt and tight-laced trousers. Anita was a slim black figure beside me, somber as Hamlet, with her pale boyish face and wavy black hair.

The gravity being maintained here on the ship we had found to be stronger than that of the Moon—rather more like Mars.

"There are the heat-rays, Gregg."

A PILE of them was visible down the deck-length. And I saw caskets of fragile glass globes, bombs of different styles; hand-projectors of the paralyzing ray; search-beams of several varieties; the Benson curve-light, and a few side-arms of ancient Earth-design—swords and dirks, and small bullet projectors.

There seemed to be some mining equipment also. Far along the deck, beyond the central cabin in the open space of the stern, steel rails were stacked; half a dozen small-wheeled ore-carts; a tiny motor engine for hauling them—and what looked as though it might be the dismembered sections of an ore-shute.

The whole deck was presently strewn with this mass of equipment.

Potan moved about, directing the different groups of workers. The news had spread that we knew the location of the treasure. The brigands were jubilant. In a few hours the ship's armament would be ready, and it would advance to attack Grantline.

I saw many glances being cast out the dome side-windows toward the distant, far-down plains of the Mare Imbrium. The brigands believed that the Grantline camp lay in that direction.

Anita whispered, "Which is their giant electronic projector, Gregg?"

I could see it amidships of the deck. It was already in place. Potan was there now, superintending the men who were connecting it. The most powerful weapon on the ship, it had, Potan said, an effective range of some ten miles. I wondered what it would do to a Grantline building! The Erentz double walls would withstand it for a time, I was sure. But it would blast an Erentz fabric-suit, no doubt of that. Like a lightning bolt, it would kill—its flashing free-stream of electrons shocking the heart, bringing instant death.

I whispered, "We must smash that before we leave! But first turn it on Miko, if he signals now."

I WAS tensely watchful for that signal. The electronic projector obviously was not yet ready. But when it was connected, I must be near it, to persuade its duty-man to fire it on Miko. With this done we would have more time to plan our other tasks. I did not think Potan would be ready for his attack before another time of sleep here in the ship's routine. Things would be quieter then—I would watch my chance to send a signal to Earth, and then we would escape.

With my thoughts roving, we had been standing quietly at the cubby door-oval for perhaps fifteen minutes. My hand in my side pouch clutched the little bullet projector. The brigands had taken it from me and given it to Potan. He had placed it on the settle with my Erentz suit; and when we gained his confidence he had forgotten it and left it there. I had it now, and the feel of its cool sleek handle gave me a measure of comfort. Things could go wrong so easily—but if they did, I was determined to sell my life as dearly as possible. And a vague thought was in my mind: I must not use the last bullet. That would be for Anita.

I shook myself free from such sinister fancy.

"That electronic projector is remote-controlled. Look, Anita—that's the signal room over us. The giant projector will be aimed and fired from up there."

It seemed so. A thirty-foot skeleton tower stood on the deck near us, with a spiral ladder leading up to a small square steel cubby at the top. Through the cubby window-ovals I could see instrument panels. A single Martian was up there; he had called down to Potan concerning the electronic projector.

THE roof of this little tower room was close under the dome—a space of no more than four feet. A pressure lock-exit in the dome was up there, with a few steps leading up to it from the roof of the tower signal-room. We could escape that way, perhaps. In the event of dire necessity it might be possible. But only as a desperate resort, for it would put us on the top of the glassite dome, with a sheer hundred feet or more down its sleek bulging exterior side, and down the outside bulge of the ship's hull, to the rocks below. There might be a spider ladder outside leading downward, but I saw no evidence of it. If Anita and I were forced to escape that way, I wondered how we could manage a hundred foot jump to the rocks and land safely. Even with the slight gravity of the Moon it would be a dangerous fall.

"You are Gregg Haljan?"

I started as one of the brigands, coming up behind us, addressed me.

"Yes."

"Commander Potan tells me you were chief navigator of the Planetara?"

"Yes."

"You shall pilot us when we advance upon the Grantline camp. I am control-commander here—Brotow, my name."

He smiled. A giant fellow, but spindly. He spoke good English. He seemed anxious to be friendly.

"We are glad to have you and George Prince's sister with us." He shot Anita an admiring glance. "I will show you our controls, Haljan."

"All right," I said. "Whatever I can do to help...."

"But not now. It will be some hours before we are ready."

I nodded, and he wandered away. Anita whispered:

"Did he mean that signal room up here in the tower? Oh, Gregg, maybe it's only the ship's control room!"

"I don't know. But the projector range-finders are up there, and I think it's the signal room."

"Suppose we go up and see? Gregg, Miko's signals might start any minute."

AND the electronic projector now seemed about ready. It was time for me to act. But a reluctant instinct was upon me. Our Erentz suits were here close behind us in Potan's cubby. I hated to leave them: if anything happened and we had to make a sudden dash, there would be no time to garb ourselves in the suits. To adjust the helmets was bad enough.

I whispered swiftly, "We must get into our suits—find some pretext." I drew her back through the cubby doorway where we would be more secluded.

"Anita, listen: I've been a fool not to plan our escape more carefully! We're in too great a danger here."

It seemed to me suddenly that we were in desperate plight. Was it premonition?

"Anita, listen: if anything happens and we have to make a dash—"

"Up through that dome-lock, Gregg? It's a manual control; you can see the levers."

"Yes. It's a manual. But up there—how would we get down?"

She was far calmer than I. "There may be an outside ladder, Gregg."

"I don't think so. I haven't seen it."

"Then we can get out the way they brought us in. The hull-porte—it's a manual, too."

"Yes, I think I can find our way down through the hull corridors. I mean, for a quick run. If we have to run, you stay close behind me. I've this bullet projector, and evidently there aren't many men in the lower corridors."

"There are guards outside on the rocks."

We had seen them through the dome windows. But there were not many—only two or three. A surprise rush at them would turn the trick.

WE donned our Erentz suits.

"What will we do with the helmets?" Anita demanded. "Leave them here?"

"No—take them with us. I'm not going to get separated from them; it's too dangerous."

"We'll look strange going up to that signal room equipped like this," she commented.

"I can't help it. We'll figure out something to explain it."

She stood before me, a queer-looking little figure in the now deflated, bagging suit with her slim neck and head protruding above the metal circle of its collar.

"Carry your helmet, Anita. I'll take mine."

We could adjust the helmets and start the Erentz motors all within a few seconds.

"I'm ready, Gregg."

"Come on, then. Let me go first."

I had the bullet projector in an outer pouch of the suit where I could instantly reach it. This was more rational: we had a fighting chance now. The fear which had swept me so suddenly began to recede. I was calm.

"We'll climb the tower to the signal room," I whispered. "Do it boldly."

We stepped from the cubby. Potan was not in sight; he was on the further deck beyond the central cabin structure perhaps, or had gone below.

On the deck, we were immediately accosted. This was different—our appearance in the Erentz suits!

"Where are you going?"

This fellow spoke in Martian. I answered in English.

"Up there."

HE stood before us, towering over me. I saw a group of nearby workers stop to regard us. In a moment we would be causing a commotion, and it was the last thing I desired.

I said in Martian, "Commander Potan told me, what I wish I can do. From the dome we look around—see where is the Grantline camp—I am pilot of this ship to go there."

The man who had called himself Brotow passed near us. I appealed to him.

"We put on our suits. I thought we might go up on the dome for a minute and look around. If I'm to pilot the ship...."

He hesitated, his glance sweeping the deck as though to ask Potan. Someone said in Martian:

"The commander is down in the stern storeroom."

It decided Brotow. He waved away the Martian who had stopped me.

"Let them alone."

Anita and I gave him our most friendly smiles.

"Thanks."

He bowed to Anita with a sweeping gesture. "I will show you over the control room presently."

His gaze went to the peak of the bow. The little hooded cubby there was the control room. Satisfaction swept me. Then this, above us in the tower, must surely be the signal room. Would Brotow follow us up? I hoped not. I wanted to be alone with the duty-man up there, giving me a chance to get at the projector controls if Miko's signal should come.

I drew Anita past Brotow, who had stood aside. "Thanks," I repeated. "We won't be long."

We mounted the little ladder.

CHAPTER XXXI
In the Tower Cubby

HURRY, Anita!"

I feared that Potan might come up from the hull at any moment and stop us. The duty-man over us gazed down, his huge head and shoulders blocking the small signal room window. Brotow called up in Martian, telling him to let us come. He scowled, but when we reached the trap in the room floor-grid, we found him standing aside to admit us.

I flung a swift glance around. It was a metallic cubby, not much over fifteen feet square, with an eight-foot arched ceiling. There were instrument panels. The range-finder for the giant projector was here; its little telescope with the trajectory apparatus and the firing switch were unmistakable. And the signalling apparatus was here! Not a Martian set, but a fully powerful Botz ultra-violet helio sender with its attendant receiving mirrors. The Planetara had used the Botz system, so I was thoroughly familiar with it. I saw, too, what seemed to be weapons: a row of small fragile glass globes, hanging on clips along the wall—bombs, each the size of a man's fist. And a broad belt with bombs in its padded compartments.

My heart was pounding as my first quick glance took in these details. I saw also that the room had four small oval window openings. They were breast-high above the floor; from the deck below I knew that the angle of vision was such that the men down there could not see into this room except to glimpse its upper portion near the ceiling. And the helio set was banked on a low table near the floor.

In a corner of the room a small ladder led through a ceiling trap to the cubby roof. This upper trap was open. Four feet above the room-roof was the arch of the dome, with the entrance to the upper exit-lock directly above us. The weapons and the belt of bombs were near this ascending ladder, evidently placed here as equipment for use from the top of the dome.

I TURNED to the solitary duty-man. I must gain his confidence at once. Anita had laid her helmet aside. She spoke first.

"We were with Set Miko," she said smilingly, "in the wreck of the Planetara. You heard of it? We know where the treasure is."

This duty-man was a full seven feet tall, and the most heavy-set Martian I had ever seen. A tremendous, beetling-browed, scowling fellow. He stood with hands on his hips, his leather-garbed legs spread wide; and as I fronted him I felt like a child. He was silent, glaring down at me as I drew his attention from Anita.

"You speak English? We are not skilled with Martian."

I wondered if at the next time of sleep this fellow would be on duty here. I hoped not; it would not be easy to trick him and find an opportunity to flash a signal. But that task was some hours away as yet; I would worry about it when the time came. Just now I was concerned with Miko and his little band, who at any moment might arrive in sight. If we could persuade this scowling duty-man to turn the projector on them....

He answered me in ready English:

"You are the man Gregg Haljan? And this is the sister of George Prince—what do you want up here?"

"I am a navigator. Brotow wants me to pilot the ship when we advance to attack Grantline."

"This is not the control room."

"No, I know it isn't."

I put my helmet carefully on the floor-grid beside Anita's. I straightened to find the brigand gazing at her. He did not speak; he was still scowling. But in the dim blue glow of the cubby I caught the look in his eyes.

I SAID hastily, "Grantline knows your ship has landed here on Archimedes. His camp is off there on the Mare Imbrium. He sent up a signal—you saw it, didn't you?—just before Miss Prince and I came aboard. He was trying to pretend that he was your Earth-party, Miko and Coniston."

"Why?"

The fellow turned his scowl on me, but Anita brought his gaze back to her. She put in quickly:

"Grantline, as Brother always said, has no great cunning. I believe he's planning now to creep up on us, catch us unaware by pretending that he is Miko."

"If he does that," I said, "we will turn this electronic projector on him and annihilate him. You have its firing mechanism here."

"Who told you so?" he shot at me.

I gestured. "I see it here. It's obvious. I'm skilled at trajectory-firing. If Grantline appears down there now, I'll help you—"

"Is it connected?" Anita demanded boldly.

"Yes," he said. "You have on your Erentz suits: are you going to the dome-roof? Then go."

But that was what we did not want to do. Anita's glance seemed to tell me to let her handle this. I turned toward one of the cubby windows; she said sweetly:

"Are you in charge of this room? Show me how that projector is operated; it will be invincible against the Grantline camp."

"Yes."

I HAD my back to them for a moment. Through the breast-high oval I could see down across the deck-space and out through the side dome windows. And my heart suddenly leaped into my throat. It seemed that down there in the Earthlit shadows, where the spreading base of the giant crater joined the plains, a light was bobbing. I gazed, stricken. Miko's lights? Was he advancing, preparing to signal? I tried to gauge the distance; it was not over two miles from here.

Or was it not a light at all? With the naked eye, I could not be sure. Perhaps there was a telescopic finder here in the cubby....

I was subconsciously aware of the voices of Anita and the duty-man behind me. Then abruptly I heard Anita's low cry. I whirled around.

The giant Martian had gathered her into his huge arms, his heavy-jowled gray face with a leering grin close to hers!

He saw me coming. He held her with one arm: his other flung at me, caught me, knocked me backward. He rasped:

"Get out of here! Go up to the dome, leave us."

Anita was silently struggling with her little hands at his thick throat. His blow flung me against a settle. But I held my feet. I was partly behind him. I leaped again, and as he tried to disengage himself from Anita to front me, her clutching fingers impeded him.

My bullet projector was in my hand. But in that second as I leaped, I had the sense to realize I should not fire it and with its noise alarm the ship. I grasped its barrel, reached upward and struck with its heavy metal butt. The blow caught the Martian on the skull, and simultaneously my body struck him.

We went down together, falling partly upon Anita. But the giant had not cried out, and as I gripped him now, I felt his body limp. I lay panting. Anita squirmed silently from under us. Blood from the giant's head was welling out, hot and sticky against my face as I lay sprawled on him.

I CAST him off. He was dead, his fragile Martian skull split open by my blow.

There had been no alarm. The slight noise we made had not been heard down on the busy deck. Anita and I crouched by the floor. From the deck all this part of the room could not be seen.

"Dead!"

"Oh, Gregg—"

It forced our hand. I could not wait now for Miko to come. But I could flash the Earth signal now, and then we would have to make our run to escape.

Abruptly I remembered that light down at the crater-base! I kept Anita out of sight on the floor and went cautiously to a window. The deck was in turmoil with brigands moving about excitedly. Not because of what had happened in our tower signal room; they were unaware of that.

Miko's signals were showing! I could see them now plainly, down at the crater-base. A group of hand-lights and a small waving helio-beam.

And they were being answered from the ship! Potan was on the deck—a babble of voices, above which his rose with roars of command. At one of the dome windows a brigand with a hand search-beam was sending its answering light. And I saw that Potan was working over a deck telescope-finder.

It had all come so suddenly that I was stunned. But I did not wait to read the signals. I swung back at Anita.

"It's Miko! And they are answering him! Get your helmet; I'll try firing the projector."

Or would I instead try to send a brief flash-signal to Earth? There would be no time to do both: we must escape out of here. The route up through the dome was the only feasible one now.

This range mechanism of the projector was reasonably familiar, and I felt that I could operate it. The range-finder and switch were on a ledge at one of the windows. I rushed to it. As I swung the little telescope, training it down on Miko's lights, I could see the huge projector on the deck swinging similarly. Its movement surprised the men who were attending it. One of them called up to me, but I ignored him.

THEN Potan looked up and saw me. He shouted in Martian at the duty-man, whom he doubtless thought was behind me: "Be ready! We may fire on them, whoever they are. I'll give you the word."

The signals were proceeding. It had only been a moment. I caught something like, "Haljan is impostor."

I was aiming the projector. I was aware of Anita at my elbow. I pushed her back.

"Put on your helmet!"

I had the range. I flung the firing switch.

At the deck window the giant projector spat its deadly electronic stream. The men down there leaped away from it with surprise. I heard Potan's voice, his shout of protest and anger.

But down in the Earthglow at the crater-base, Miko's lights had not vanished! I had missed! An error in the range? Abruptly I knew it was not that. Miko's lights were still there. His signals still coming. And I remarked now a faint distortion about them, the glow of his little group of hand-lights faintly distorted and vaguely shot with a greenish cast. Benson curve-lights! I realized it.

My thoughts whirled in the few seconds while I stood there at the tower window. Miko had feared he might summarily be fired upon. He had gone back to his camp, equipped all his lights with the Benson curve. He was somewhere at the crater-base now. But not where I thought I saw him! The Benson curve-light changed the path of the light-rays traveling from him to me—I could not even approximate his true position!

Anita was plucking at me. "Gregg, come."

"I can't hit him!" I gasped.

Should I try the flash-signal to Earth? Did we dare linger here? I stood another few seconds fascinated at the window. I saw Potan down in the confusion of the deck, training a telescope. He had shouted up violently at his duty-man here not to fire again.

And now he suddenly let out a roar. "I can see them! It's Miko! By the Almighty—his giant stature—Brotow, look! That's not an Earthman!"

He flung aside his little telescope finder. "Disconnect that projector! It's Miko down there! This Haljan is a trickster! Where is he? Braile—Braile, you accursed fool! Are Haljan and the girl up there with you?"

But the duty-man lay weltering in his blood at our feet.

I had dropped back from the window. Anita and I crouched for an instant in confusion, fumbling with our helmets.

The ship rang with the alarm. And amid the turmoil we could hear the shouts of the infuriated brigands swarming up the tower ladder after us!

CHAPTER XXXII
A Speck Amid the Stars

I WAS only inactive a moment. I had thought Anita would have on her helmet. But she was reluctant, or confused.

"Gregg."

"We've got to get out of here! Up through the overhead locks to the dome."

"Yes—" She fumbled with the helmet. Under the floor-grid the climbing men on the ladder were audible. They were already nearing the top. The trap door was closed: Anita and I were crouching on it. There was a thick metal bar set in a depressed groove of the grid. I slid it in place—it would seal the trap for a time, at any rate.

A degree of confidence came to me. We had a few moments before there could be any hand-to-hand conflict. That giant electronic projector would eventually be used against Grantline: it was the brigands' most powerful weapon. Its controls were here—by Heaven, I would smash them! That at least I could do!

I jumped for the window. Miko's signals had stopped, but I caught a glimpse of his distant moving curve-lights.

A flash came up at me, as in the window I became visible to the brigands on the ship's deck. It was a small hand-projector, hastily fired, for it went wide of the window. It was followed by a rain of small beams, but I was warned and I dropped my head beneath the high sill. The rays flashed diagonally upward through the oval opening, hissed against our vaulted roof. The air snapped and tingled with a shower of blue-red sparks, and the acrid odor of the released gases settled down upon me.

THE trajectory controls of the projector were beside me. I seized them, ripped and tore at them. There was a roar down on the deck. The projector had exploded. A man's agonized scream split the confusion of sounds.

It silenced the brigands on the deck. Under our floor-grid those on the ladder had been pounding at the trap-door. They stopped, evidently to see what had happened. The bombardment of our windows ceased momentarily.

I cautiously peered out the window again. In the wreck of the projector three men were lying. One of them was screaming horribly. The dome-side was damaged. Potan and other men were frantically investigating to see if the ship's air were hissing out.

A triumph swept me. They had not found me so meek and inoffensive as they might have thought!

Anita clutched at me. She still had not donned her helmet.

"Put it on!"

"But Gregg—"

"Put it on!"

"I—I don't want to put it on until you put yours on."

"I've smashed the projector! We've stopped them coming up for a while."

But they were still on the ladder under our floor. They heard our voices; they began thumping again. Then pounding. They seemed now to have some heavy implement. They rammed with it against the trap.

But the floor seemed holding. The square of metal grid trembled, yielded a little. But it was good for a few minutes longer.

I called down, "The first one who comes through will be shot." My words mingled with their oaths. There was a moment's pause, then the ramming went on. The dying man on the deck was still screaming.

I WHISPERED, "I'll try an Earth-signal."

She nodded. Pale, tense, but calm. "Yes, Gregg. And I was thinking—"

"It won't take a minute. Have your helmet ready."

"I was thinking—"

She hurried across the room. I swung on the Botz signaling apparatus. It was connected. Within a moment I had it humming. The fluorescent tubes lighted with their lurid glare; they painted purple the body of the giant duty-man who lay sprawled at my feet. I drew on all the ship's power. The tube-lights in the room quivered and went dim.

I would have to hurry. Potan could shut this off from the main hull control room. I could see, through the room's upper trap, the primary sending mirror mounted in the peak of the dome. It was quivering, radiant with its light-energy. I sent the flash.

The flattened, past-full Earth was up there. I knew that the western hemisphere faced the Moon at this hour. I flashed in English, with the open Universal Earth-code:

"Help! Grantline."

And again: "Send help! Archimedes region near Apennines. Attacked by brigands. Send help at once! Grantline!"

If only it would be received! I flung off the current. Anita stood watching me intently. "Gregg, look!"

She had taken some of the glass globe-bombs which lay by the foot of the ascending ladder. She held some of them now.

"Gregg. I threw some."

AT the window we gazed down. The globes she flung had shattered on the deck. They were occulting darkness bombs.⁵

5: Filled with an odorless, harmless gas, these bombs were used in warfare, taking the place of the old-fashioned smoke screens. The diffusing gas was of such a nature that, when released, it absorbed within itself all the color inherent to the light-rays striking it, thus creating a temporary darkness.

Through the blackness of the deck, the shouts of the brigands came up. They were stumbling about. But the ramming of our trap went on, and I saw that it was beginning to yield. One corner of it was bent up.

"We've got to go, Anita!"

"Yes."

From out of the darkness which hung like a shroud over the deck an occasional flash came up, unaimed—wide of our windows. But the darkness was dissipating. I could see now the dim glow of the deck lights, blurred as through a heavy fog.

I dropped another of the bombs.

"Put on your helmet."

"Yes—yes, I will. You put on yours."

We had them adjusted in a moment. Our Erentz motors were pumping.

I gripped her. "Put out your helmet-light."

She extinguished it. I handed her my bullet projector.

"Hold it a moment. I'm going to take that belt of bombs."

The trap-door was all but broken under the ramming blows of the men on the ladder. I leaped over the body of the duty-man, seized the belt of bombs and strapped it about my waist.

Anita stood with me.

"Give me the projector."

She handed it to me. The trap-door burst upward! A man's head and shoulders appeared. I fired a bullet into him—the little leaden pellet singing down through the yellow powder-flash that spat from the projector's muzzle.

THE brigand screamed, and dropped back out of sight. There was confusion at the ladder-top. I flung a bomb at the broken trap. A tiny heat-ray came wavering up through the opening, but went wide of us.

The instrument room was in darkness. I clung to Anita.

"Hold on to me! You go first—here is the ladder."

We found it in the blackness, mounted it and went through the cubby's roof-trap.

I took a hasty look and dropped another bomb beside us. The four-foot space up here between the cubby roof and the overhead dome went black. We were momentarily concealed.

Anita located the manual levers of the lock-entrance.

"Here, Gregg."

I shoved at them. Fear leaped in me that they would not operate. But they swung. The tiny porte opened wide to receive us. We clambered into the small air-chamber; the door slid closed, just as a flash from below struck at it. The brigands had seen our little cloud of darkness and were firing up through it.

We were through the locks in a moment, out on the open dome-top. A sleek, rounded spread of glassite, with broad aluminite girders. There were cross-ribs which gave us footing, and occasional projections—streamline fin-tips, the casings of the upper rudder shafts, and the upstanding stubby funnels into which the helicopters were folded.

We moved along the central footpath and crouched by a six-foot casing. The stars and the glowing Earth were over us. The curving dome-top—a hundred feet or so in length, and bulging thirty feet wide beneath us—glistened in the Earthlight. It was a sheer drop down these curving sides past the ship's hull, a hundred feet to the rocks on which the vessel rested. The towering wall of Archimedes was beside us; and beyond the brink of the ledge the thousands of feet down to the plains.

I SAW the lights of Miko's band down there. He had stopped signaling. His little lights were spread out, bobbing as he and his men advanced up the crater's foothills, coming to join their ship.

I had an instant's glimpse. Anita and I could not stay here. The brigands would follow us up in a moment. I saw no exterior ladder. We would have to take our chances and jump.

There were brigands down there on the rocks. I saw three or four skulking helmeted figures, and they saw us! A bullet whizzed by us, and then came the flash of a hand-ray.

I touched Anita. "Can you make the leap? Anita, dear...."

Again it seemed that this must be farewell.

"Gregg, dear one—oh, we've got to do it!"

Those waiting figures would pounce on us.

"Anita, lie here a moment."

I jumped up and ran twenty feet toward the bow; then back, toward the stern, flinging down the last of my bombs. The darkness was like a cloud down there, enveloping the outer brigands. But up here we were above it, etched by the starlight and Earthglow.

I came back to Anita.

"We'll have to chance it now."

"Gregg...."

"Good-by, dear. I'll jump first, down this side—you follow."

To leap into that black patch, with the rocks under it....

"Gregg—"

She was trying to tell me to look overhead. She gestured. "Gregg, see!"

I saw it out over the plains—a little speck amid the stars. A moving speck, coming toward us!

"Gregg, what is it?"

I GAZED, held my breath. A moving speck out there. A blob now.

And then I realized that it was not a large object, far away, but small, and already very close—only a few hundred feet off, dropping toward the top of our dome. A narrow, flat, ten-foot object, like a wingless volplane. There were no lights on it, but in the Earthlight I could see two crouching, helmeted figures riding it.

"Anita! Don't you remember!"

I was swept with dawning comprehension. Back in the Grantline camp Snap and I had discussed how to use the Planetara's gravity plates. We had gone to the wreck and secured them, had rigged this little volplane flyer....

The brigands on the rocks saw it now. A flash went up at it. One of the figures crouching on it opened a flexible fabric like a wing over its side. I saw another flash from below, harmlessly striking the insulated shield.

I gasped to Anita, "Light your helmet! It's from Grantline! Let them see us!"

I stood erect. The little flying platform went over us, fifty feet up, circling, dropping to the dome-top.

I waved my helmet-light. The exit-lock from below—up which we had come—was near us. The advancing brigands were already in it! I had forgotten to demolish the manuals. And I saw that the darkness down on the rocks was almost gone now, dissipating in the airless night. The brigands down there began firing up at us.

It was a confusion of flashing lights. I clutched at Anita.

"Come this way—run!"

The platform barely missed our heads. It sailed lengthwise of the dome-top, and crashed silently on the central runway near the stern-tip. Anita and I ran to it.

The two helmeted figures seized us, shoved us prone on the metal platform. It was barely four feet wide: a low railing, handles with which to cling, and a tiny hooded cubby in front, with banks of controls.

"Gregg!"

"Snap!"

It was Snap and Venza. She seized Anita, held her crouching in place. Snap flung himself face down at the controls.

The brigands in the lock were out on the dome now. I took a last shot as we lifted. My bullet punctured one of them; he fell, slid scrambling off the rounded dome and dropped out of sight.

Light-rays and silent flashes seemed to envelop us. Venza held the side-shields higher.

We tilted, swayed crazily, and then steadied.

The ship's dome dropped away beneath us. The rocks of the open ledge were under us. Then the abyss, with the moving climbing specks of Miko's lights far down.

I saw, over the side-shield, the already distant brigand ship resting on the ledge with the massive Archimedes' wall behind it. A confusion back there of futile flashing rays.

It all faded into a remote glow as we sailed smoothly up into the starlight and away, heading for the Grantline camp.

CHAPTER XXXIII
Besieged!

WAKE up, Gregg! They're coming!"

I forced myself to consciousness. "Coming—"

"Yes. Wake up!"

I leaped from my bunk, followed Snap with a rush into the corridor. We had returned safely to the Grantline Camp. Anita and I found ourselves exhausted from lack of sleep, our arduous climb of Archimedes and that tense time on the brigand ship. On the flight back Snap had explained how the landing of the ship on Archimedes was observed through the Grantline telescope, using but little of its power for this local range. They had read with amazement my signals to the brigands. Snap had rushed to completion the first of our contemplated flying platforms. Then he had seen Miko's signals from the crater-base, seen the lights of the fight to capture Anita and me in the cubby, and had come to rescue us.

Back at the camp we were given food, and Grantline forced me to try and sleep.

"They'll be on us in a few hours, Gregg. Miko will have joined them by now. He'll lead them to us. You must rest, for we need everyone at his best."

And surprisingly, in the midst of the camp's turmoil of last minute activities, I slept soundly, until Snap called me that the ship was coming.

The corridor echoed with the tramp of Grantline's busy crew. But there was no confusion now; a grim calmness had settled upon everyone.

Anita and Venza rushed up to join us. "It's in sight!"

THERE was no need of going to the instrument room. From the windows fronting the brink of the cliff the brigand ship was plainly visible. It came sailing from Archimedes, a dark shape blurring the stars. All its lights were extinguished save a single white search-beam in the bow-peak, slanting diagonally down.

The beam presently caught our little group of buildings; its glare shone in the windows as it clung for a moment. I could envisage the triumphant curiosity, of Potan and his fellows up there, gazing along the beam.

Then it swung away. The ship was at an altitude of no more than three thousand feet when I first saw it, coming upon a level keel. Would it circle over us, firing at us? Or sail past, after inspecting us? Or land, perhaps, boldly crowded upon our little ledge?

We were ready—as ready as we could be with our meager equipment. The camp was in a state of siege. The cliff-lights were extinguished: the interior lights were dim, save in the workshops of the main building, where the final assembling of Snap's other flying platforms and their insulated protective shields was still in progress.

We had dimmed the lights to conserve our power, and to enable the Erentz motors to run at full capacity. Our buildings would have to withstand the brigand rays which soon would be upon us.

Outside on our dim, Earthlit cliff, the tiny lights showed where our few guards were lurking. As I stood at the window watching the oncoming ship, Grantline's voice sounded:

"Call in those men! Ring the call-lights, Franck!"

The siren buzzed over the camp's interior; the warning call-lights on the roof brought in the outer guards. They came running to the admission portes, which had been repaired after Miko disabled them.

THE guards came in. We dimmed our lights further. The treasure sheds were black against the cliff behind us. No need for guards there—the bulk of the ore was such that we reasoned the brigands would not attempt to move it until our buildings were captured. But, if they should try it, we were prepared to sally out with our hand-weapons and defend it.

In the dim lights we crouched. A silence was upon us, save for the clanging in the workshop down the corridor. Most of us wore our Erentz suits, with helmets ready, though I am sure there was not a man of us but who prayed he might not have to go out. At many of the windows—our weakest points to withstand the rays—insulated fabric shields were hung like curtains.

The brigand ship slowly advanced. It was soon over the opposite rim of our little crater. Its search-beam swung about the rim and down into the valley.

My thoughts ran like a turgid stream as I stood tensely watching.

Four hours ago I had sent that flash-signal to Earth. If it were received, a patrol-ship could come to our rescue and arrive here in another eight hours—or perhaps even less.

Ah, that "if!" If the signal were received! If the patrol-ship were immediately available! If it started at once....

Eight hours at the very least. I tried to assure myself that we could hold out that long....

The brigand ship crossed the opposite crater-rim. It dropped lower. It seemed poised over the crater-valley, almost at our own level and less than two miles from us. Its search-beam vanished. For a moment it hung, a sleek, cylindrical silver shape, gleaming in the Earthlight.

Snap looked at me and murmured, "It's descending."

It slowly settled, cautiously picked its landing-place amid the crags and pits of the tumbled scarred valley floor. It came to rest, a vague silver menacing shape lurking in the lower shadows, close at the foot of the inner opposite crater-wall.

A few moments of tense waiting passed. Soon tiny lights were moving down there, some out on the rocks near the ship, others up under its deck-dome.

A stab of searchlight shot across the valley, swung along our ledge and clung with its glaring ten-foot circle to the front of our main building. Then a ray flashed.

The assault had begun!

CHAPTER XXXIV
The First Encounters

IT seemed, with that first shot from the enemy, that a great relief came to me—an apprehension fallen away. We had anticipated this moment for so long, dreaded it. I think all our men felt it. A shout went up:

"Harmless!"

It was not that. But our building withstood it better than I had feared. It was a flash from a large electronic projector mounted on the deck of the brigand ship. It stabbed up from the shadows across the valley at the foot of the opposite crater-wall, a beam of vaguely fluorescent light. Simultaneously the search-light vanished.

The stream of electrons caught the front face of our main building in a six-foot circle. It held a few seconds, vanished; then stabbed again, and still again. Three bolts. A total, I suppose, of nine or ten seconds.

I was standing with Grantline at a front window. We had rigged an oblong of insulated fabric like a curtain: we stood peering, holding the curtain cautiously aside. The ray struck some twenty feet away from us.

"Harmless!"

The men in the room shouted it with derision. But Grantline swung on them.

"Don't think that!"

An interior signal-panel was beside Grantline. He called the duty-men in the instrument room.

"It's over. What are your readings?"

THE bombarding electrons had passed through the outer shell of the building's double-wall, and been absorbed in the rarefied, magnetized air-current of the Erentz circulation. Like poison in a man's veins, reaching his heart, the free alien electrons had disturbed the motors. They accelerated, then retarded. Pulsed unevenly, and drew added power from the reserve tanks. But they had normalized at once when the shot was past. The duty-man's voice sounded from the grid in answer to Grantline's question:

"Five degrees colder in your building. Can't you feel it?"

The disturbed, weakened Erentz circulation had allowed the outer cold to radiate through a trifle. The walls had had a trifle extra explosive pressure from the room-air. A strain—but that was all.

"It's probably their most powerful single weapon, Gregg." Grantline said.

I nodded. "Yes. I think so."

I had smashed the real giant, with its ten-mile range. The ship was only two miles from us, but it seemed as though this projector were exerted to its distance limit. I had noticed on the deck only one of this type. The others, paralyzing-rays and heat rays, were less deadly.

Grantline commented: "We can withstand a lot of that bombardment. If we stay inside—"

That ray, striking a man outside, would penetrate his Erentz suit within a few seconds, we could not doubt. We had, however, no intention of going out unless for dire necessity.

"Even so," said Grantline. "A hand-shield would hold it off for a certain length of time."

WE had an opportunity a moment later to test our insulated shields. The bolt came again. It darted along the front face of the building, caught our window and clung. The double window-shells were our weakest points. The sheet of flashing Erentz current was transparent: we could see through it as though it were glass. It moved faster, but was thinner at the windows than in the walls. We feared the bombarding electrons might cross it, penetrate the inner shell and, like a lightning bolt, enter the room.

We dropped the curtain corner. The radiance of the bolt was dimly visible. A few seconds, then it vanished again, and behind the shield we had not felt a tingle.

"Harmless!"

But our power had been drained nearly an aeron, to neutralize the shock to the Erentz current. Grantline said:

"If they kept that up, it would be a question of whose power supply would last longest. And it would not be ours.... You saw our lights fade down while the bolt was striking?"

But the brigands did not know we were short of power. And to fire the projector with a continuous bolt would, in thirty minutes, perhaps, have exhausted their own power-reserve.

This strange warfare! It was new to all of us, for there had been no wars on any of the three inhabited worlds for many years. Silent, electronic conflict! Not a question of men in battle. A man at a switch on the brigand ship was the sole actor so far in this assault. And the results were visible only in the movement of the needle-dials on our instrument panels. A struggle, so far, not of man's bravery, or skill, or strategy, but merely of electronic power supply.

YET warfare, however modern, can never transcend the human element. Before this insult was ended I was to have many demonstrations of that!

"I won't answer them," Grantline declared. "Our game is to sit defensive. Conserve everything. Let them make the leading moves."

We waited half an hour, but no other shot came. The valley floor was patched with Earthlight and shadow. We could see the vague outline of the brigand ship backed up at the foot of the opposite crater-wall. The form of its dome over the illumined deck was visible, and the line of its tiny hull ovals.

On the rocks near the ship, helmet-lights of prowling brigands occasionally showed.

Whatever activity was going on down there we could not see with the naked eye. Grantline did not use our telescope at first. To connect it, even for local range, drew on our precious ammunition of power. Some of the men urged that we search the sky with the telescope. Was our rescue ship from Earth coming? But Grantline refused. We were in no trouble yet. And every delay was to our advantage.

"Commander, where shall I put these helmets?"

A man came wheeling a pile of helmets on a little truck.

"At the manual porte—other building."

Our weapons and outside equipment were massed at the main exit-locks of the large building. But we might want to sally out through the smaller locks also. Grantline sent helmets there; suits were not needed, as most of us were garbed in them now, but without the helmets.

SNAP was still in the workshop. I went there during this first half-hour of the attack. Ten of our men were busy there with the little flying platforms and the fabric shields.

"How is it, Snap?"

"Almost all ready."

He had six of the platforms, including the one we had already used, and more than a dozen hand-shields. At a squeeze, all of us could ride on these six little vehicles. We might have to ride them! We planned that, in the event of disaster to the buildings, we could at least escape in this fashion. Food supplies and water were now being placed at the portes.

Depressing preparations! Our buildings uninhabitable, a rush out and away, abandoning the treasure.... Grantline had never mentioned such a contingency, but I noticed, nevertheless, that preparations were being made.

"Only that one shot, Gregg?"

Snap's voice was raised over the clang of the workmen bolting the little gravity-plates of the last platform.

"Four blasts. But just the one projector. Their strongest."

He grinned. He wore no Erentz suit as yet. He stood in torn grimy work-trousers and a bedraggled shirt, with the inevitable red eyeshade holding back his unruly hair. Around his waist was the weighted belt and there were weights on his shoes for gravity stability.

"Didn't hurt us much."

"No."

"When I get the tube-panels in this thing I'll be finished. It'll take another half-hour. I'll join you. Where are you stationed?"

I SHRUGGED. "I was at a front window with Johnny. Nothing to do as yet."

Snap went back to his work. "Well, the longer they delay, the better for us. If only your signal got through, Gregg! We'll have a rescue ship here in a few hours more."

Ah, that "if!"

I turned away. "Can't help you, Snap?"

"No. Take those shields," he added to one of the men.

"Take them where?"

"To Grantline. The front admission porte, or the back. He'll tell you which."

The shields were wheeled away on a little cart. I followed it. Grantline sent it to the back exit.

"No other move from them yet, Johnny?"

"No. All quiet."

"Snap's almost finished."

The brigands presently made another play. A giant heat-ray beam came across the valley. It clung to our front wall for nearly a minute.

Grantline got the reports from the instrument room. He laughed.

"That helped rather than hurt us. Heated the outer wall. Frank took advantage of it and eased up the motors."

We wondered if Miko knew that. Doubtless he did, for another interval passed and the heat-ray was not used again.

THEN came a zed-ray. I stood at the window, watching it, faint sheen of beam in the dimness. It crept with sinister deliberation along our front building-wall, clung momentarily to our shielded windows and pried with its revealing glow into Snap's workshop.

"Looking us over," Grantline commented. "I hope they like what they see."

I knew he did not feel the bravado that was in his tone. We had nothing but small hand weapons: heat-rays, electronic projectors, and bullet projectors. All for very short-range fighting. If Miko had not known that before, he could at least make a good guess at it after the careful zed-ray inspection. With his ship down there two miles away, we were powerless to reach him.

It seemed that Miko was now testing the use of all his mechanisms. A light-flare went up from the dome-peak of the ship. It rose in a slow arc over the valley, and burst. For a few seconds the two-mile circle of crags was brilliantly illumined. I stared, but I had to shield my eyes against the dazzling actinic glare, and I could see nothing. Was Miko making a zed-ray photograph of our interiors? We had no way of knowing.

He was testing his short-range projectors now. With my eyes again accustomed to the normal Earthlight in the valley, I could see the stabs of little electronic beams, the Martian paralyzing-rays and heat-beams. They darted out like flashing swords from the rocks near the ship.

Then the whole ship and the crater-wall behind it seemed to shift sidewise as a Benson curve-light spread its glow about the ship, with a projector curve-beam coming up and touching the window through which I was peering.

"Haljan, come look at these damn girls! Commander—shall I stop them? They'll kill themselves, or kill us—or smash something!"

WE followed the man into the building's broad central corridor. Anita and Venza were riding a midget flying platform! Anita, in her boyish black garb; Venza with a flowing white Venus-robe. They lay on the tiny, six-foot oblong of metal, one manipulating its side shields, the other at the controls. As we arrived, the platform came sliding down the narrow confines of the corridor, lurching, barely missing a door-grid projection. Up to skim the low vaulted ceiling, then down to the floor.

It sailed past our heads, rising over us as we ducked. Anita waved her hand.

Grantline gasped, "By the infernal!"

I shouted, "Anita, stop!"

But they only waved at us, skimming down the length of the corridor, seeming to avoid a smash a dozen times by the smallest margin of chance, stopping miraculously at the further end, hanging poised in mid-air, wheeling, coming back, undulating up and down.

Grantline clung to me. "By the gods of the airways!"

In spite of my astonished horror I could not but share Grantline's obvious admiration. Three of four other men were watching. The girls were amazingly skillful, no doubt of that. There was not a man among us who could have handled that gravity-platform indoors, not one who would have had the brash temerity to try it.

The platform landed with the grace of a humming bird at our feet, the girls dexterously balancing so that it came to rest swiftly, without the least bump.

I confronted them. "Anita, what are you doing?"

She stood up, flushed and smiling.

"Practising."

Imperturbable girls! The product of their age. Oblivious to the brigand attack, they were in here practising!

"What for?" I demanded.

Venza's roguish eyes twinkled at me. Her hands went to her slim hips with a gesture of defiance.

She asked, "Are you speaking for yourself or the commander?"

I IGNORED her. "What for?" I reiterated.

"Because we're good at it," Anita retorted. "Better than any of you men. If you should need us...."

"We don't. We won't." I said shortly.

"But if you should...."

Venza put in, "If Snap and I hadn't come for you, you wouldn't be here, Gregg Haljan. I didn't notice you were so horrified to see me holding that shield up over you!"

It silenced me.

She added, "Commander, let us alone. We won't smash anything."

Grantline laughed, "I hope you won't!"

A warning call took us back to the front window. The brigand's search-beam was again being used. It swept slowly along the length of the cliff. Its circle went down the cliff steps to the valley floor, and came sweeping up again. Then it went up to the observatory platform at the summit above us, then back and crept over to the ore-sheds.

We had no men outside, if that was what the brigand wanted to determine. The search-beam presently vanished. It was replaced immediately by a zed-ray, which darted at once to our treasure sheds and clung.

That stung Grantline into his first action. We flung our own zed-ray down across the valley. It reached the brigand ship; this zed-ray and a search-light were our only two projectors of long range.

The brigand ray vanished when ours flashed on. I was with Grantline at an image grid in the instrument room. We saw the deck of the brigand ship and the blurred interior of the cabins.

"Try the search-beam, Franck. We don't need the other."

The zed-ray went off. We gazed down our search-light which clung to the dome of the distant enemy vessel. We could see movement there.

"The telescope," Grantline ordered.

THE little dynamos hummed. The telescope-finder glowed and clarified. On the deck of the ship we saw the brigands working with the assembling of ore-carts. A deck landing-porte was open. The ore-carts were being carried out through a porte-lock and down a landing incline. And on the rocks outside, we saw several of the carts—and rail-sections and the sections of an ore-shute.

Miko was unloading his mining apparatus! He was making ready to come up for the treasure!

The discovery, startling as it was, nevertheless was far overshadowed by an imperative danger alarm from our main building. Brigands were outside on our ledge! Miko's search-beam, sweeping the ledge a moment before, had carefully avoided revealing them. It had been done just for that purpose, no doubt—making us sure that the ledge was unoccupied and thus to guard against our own light making a search.

But there was a brigand group here close outside our walls! By the merest chance the radiating glow from our search-ray had shown the helmeted figures scurrying for shelter.

Grantline leaped to his feet.

We rushed for the rear exit-porte which was nearest us. The giant bloated figures had been seen running along the outside of the connecting corridor, in this direction. But before we ever got there, a new alarm came. A brigand was crouching at a front corner of the main building! His hydrogen heat-torch had already opened a rift in the wall!

CHAPTER XXXV
Desperate Offensive

IN with you!" ordered Grantline. "Get your helmets on! How many? Six? Enough—get back there, Williams—you were last. The lock won't hold any more."

I was one of the six who jammed into the manual exit lock. We went through it: in a moment we were outside. It was less than three minutes since the prowling brigands had been seen.

Grantline touched me just as we emerged. "Don't wait for orders! Get them!"

"That fellow with the torch, the most dangerous—"

"Yes! I'm with you."

We went out with a rush. We had already discarded our shoe and belt weights. I leaped, regardless of my companions.

The scurrying Martians had disappeared. Through my visor bull's-eye I could see only the Earthlit rocky surface of the ledge. Beside me stretched the dark wall of our building.

I bounded toward the front. The brigand with the torch had been at this front corner. I could not see him from here: he had been crouching just around the angle.

I had a tiny bullet projector, the best weapon for short range outdoors. I was aware of Grantline close behind me.

It took only a few of my giant leaps. I landed at the corner, recovered my balance, and whirled around to the front.

The Martian was here, a giant misshapen lump as he crouched. His torch was a little stab of blue in the deep shadow enveloping him. Intent upon his work, he did not see me. Perhaps he thought his fellows had broken our exits by now.

I LANDED like a leopard upon his back and fired, my weapon muzzle ramming him. His torch fell hissing with a silent rain of blue fire upon the rocks.

As my grip upon him made audiphone contact, his agonized scream rattled the diaphragms of my ear-grids with horrible, deafening intensity.

He lay writhing under me, then was still. His scream choked into silence. His suit deflated within my encircling grip. He was dead; my leaden, steel-tipped pellet had punctured the double surface of his Erentz-fabric, penetrated his chest.

Grantline's following leap landed him over me.

"Dead?"

"Yes."

I climbed from the inert body. The torch had hissed itself out. Grantline swung on our building corner, and I leaned down with him to examine it. The torch had fused and scarred the surface of the wall, burned almost through. A pressure-rift had opened. We could see it, a curving gash in the metal wall-plate like a crack in a glass window-pane.

I went cold. This was serious damage! The rarefied Erentz-air would seep out. It was leaking now: we could see the magnetic radiance of it all up the length of the ten-foot crack. The leak would change the pressure of the Erentz system, constantly lower it, demanding steady renewal. The Erentz motors would overheat; some might go bad from the strain.

Grantline stood gripping me.

"Damn bad!"

"Yes. Can't we repair it, Johnny?"

"No. Have to take that whole plate-section out, shut off the Erentz plant and exhaust the interior air of all this bulkhead of the building. Day's job—maybe more."

AND the crack would get worse, I knew. It would gradually spread and widen. The Erentz circulation would fail. All our power would be drained struggling to maintain it. This brigand who had unwittingly committed suicide by his daring act had accomplished more than he perhaps had realized. I could envisage our weapons, useless from lack of power. The air in our buildings turning fetid and frigid: ourselves forced to the helmets. A rush out to abandon the camp and escape. The buildings exploding—scattering into a litter on the ledge like a child's broken toy. The treasure abandoned, with the brigands coming up and loading it on their ship.

Our defeat. In a few hours now—or minutes. This crack could slowly widen, or it could break suddenly at any time. Disaster, come now so abruptly upon us at the very start of the brigand attack....

Grantline's voice in my audiphone broke my despairing rush of thoughts. "Bad. Come on, Gregg; nothing to do here."

We were aware that our other four men had run along the building's other side. They emerged now—with the running brigands in front of them, rushing out toward the staircase on the ledge. Three giant Martian figures in flight, with our four men chasing.

A bullet projector spat, with its queer stab of exploding powder fed by the burning oxygen fumes of its artificial air-chamber—one of our men firing. A brigand fell to the rocks by the brink of the ledge. The others reached the descending staircase, tumbled down it with reckless leaps.

Our men turned back. Before we could join them, the enemy ship down in the valley sent up a cautious search-beam which located its returning men. Then the beam swung up to the ledge, landed upon us.

We stood confused, blinded by the brilliant glare. Grantline stumbled against me.

"Run, Gregg! They'll be firing at us."

We dashed away. Our companions joined us, rushing back for the porte. I saw it open, reinforcements coming out to help us—half a dozen figures carrying a ten-foot insulated shield. They could barely get it out through the porte.

THE Martian search-ray abruptly vanished. Then almost instantly the electronic ray came with its deadly stab. Missed us at first, as we ran for the shield. It vanished, and stabbed again. It caught us, but now we were behind the shield, carrying it back to the porte, hiding behind it.

The ray stabbed once or twice more.

Whether Miko's instruments showed him how serious that damage was to our front wall, we never knew. But I think that he realized. His search-beam clung to it, and his zed-ray pried into our interiors.

The brigand ship was active now. We were desperate: we used our telescope freely for observation. And used our zed-ray and search-light. Miko's ore-carts and mining apparatus were unloaded on the rocks. The rail-sections were being carried a mile out, nearly to the center of the valley. A subsidiary camp was being established there, only a mile from the base of our cliff, but still far beyond reach of our weapons. We could see the brigand lights down there.

Then the ore-shute sections were brought over. We could see Miko's men carrying some of the giant projectors, mounting them in the new position. Power tanks and cables. Light-flare catapults—little mechanical cannons for throwing the bombs.

The enemy search-light constantly raked our vicinity. Occasionally the giant electronic projector flung up its bolt as though warning us not to dare leave our buildings.

HALF an hour went by. Our situation was even worse than Miko could know. The Erentz motors were running hot—our power draining, the crack widening. When it would break we could not tell; but the danger was like a sword over us.

An anxious thirty minutes for us, this second interlude. Grantline called a meeting of all our little force, with every man having his say. Inactivity was no longer a feasible policy. We recklessly used our power to search the sky. Our rescue ship might be up there; but we could not see it with our disabled instruments. No signals came. We could not—or, at least, did not—receive them.

"They wouldn't signal," Grantline protested. "They'd know the Martians would be more likely to get the signal than us. Of what use to warn Miko?"

But he did not dare wait for a rescue ship that might or might not be coming! Miko was playing the waiting game now—making ready for a quick loading of the ore when we were forced to abandon our buildings.

The brigand ship suddenly moved its position! It rose up in a low flat arc, came forward and settled in the center of the valley where the carts and rail-sections were piled, and the outside projectors newly mounted on the rocks. But the projectors only shot at us occasionally.

The brigands now began laying the rails from the ship toward the base of our cliff. The chute would bring the ore down from the ledge, and the carts would take it to the ship.

The laying of the rails was done under cover of occasional stabs from the electronic projector.

And then we discovered that Miko had made still another move. The brigand rays, fired from the depths of the valley, could strike our front building, but could not reach all our ledge. And from the ship's new and nearer position this disadvantage was intensified. Then abruptly we realized that under cover of darkness-bombs an electronic projector and search-ray had been carried to the top of the crater-rim, diagonally across and only half a mile from us. Their beams shot down, raking all our vicinity from this new angle.

I WAS on the little flying platform which sallied out as a test to attack these isolated projectors. Snap and I and one other volunteer went. He and I held the shield; Snap handled the controls.

Our exit-porte was on the lee side of the building from the hostile search-beam. We got out unobserved and sailed upward; but soon a light from the ship caught us. And the projector bolts came up....

Our sortie only lasted a few minutes. To me, it was a confusion of crossing beams, with the stars overhead, the swaying little platform under me, and the shield tingling in my hands when the blasts struck us. Moments of blurred terror....

The voice of the man beside me sounded in my ears: "Now, Haljan, give them one!"

We were up over the peak of the rim with the hostile projectors under us. I gauged our movement, and dropped an explosive powder bomb.

It missed. It flared with a puff on the rocks, twenty feet from where the two projectors were mounted. I saw that two helmeted figures were down there. They tried to swing their grids upward, but could not get them vertical to reach us. The ship was firing at us, but it was far away. And Grantline's search-beam was going full-power, clinging to the ship to dazzle them.

Snap circled us. As we came back I dropped another bomb. Its silent puff seemed littered with flying fragments of the two projectors and the bodies of the men.

We flew swiftly back and got in.

IT decided Grantline. For an hour past Snap and I had been urging our plan to use the gravity platforms. To remain inactive was sure defeat now. Even if our buildings did not explode—if we thought to huddle in them, helmeted in the failing air—then Miko could readily ignore us and proceed with his loading of the treasure under our helpless gaze. He could do that now with safety—if we refused to sally out—for we could not fire our weapons through our windows.¹

1: To fire a projector through the walls or windows would at once wreck the protective Erentz system. The enemy ship has pressure portes, constructed for the emission of the weapon-rays. Grantline's only weapons thus mounted were his search-beam and zed-ray.

To remain defensive would end inevitably in our defeat. We all knew it now; it was obvious. The waiting game was Miko's—not ours! And he was playing it.

The success of our attack upon the distant isolated projectors heartened us. Yet it was a desperate offensive indeed upon which we now decided!

We prepared our little expedition at the larger of the exit portes. Miko's zed-ray was watching all our interior movements. We made a brave show of activity in our workshop with abandoned ore-carts which were stored there. We got them out, started to recondition them.

It seemed to fool Miko. His zed-ray clung to the workshop, watching us. And at the distant porte we gathered the little platforms, the shields, helmets, bombs, and a few hand-projectors.

There were six platforms—three of us upon each. It left four people to remain indoors.

I NEED not describe the emotion with which Snap and I listened to Venza and Anita pleading to be allowed to accompany us. They urged it upon Grantline, and we took no part. It was too important a decision. The treasure—the life or death of all these men—hung now upon the fate of our venture. Snap and I could not intrude our personal feelings.

And the girls won. Both were undeniably more skilful at handling the midget platforms than any of us men. Two of the six platforms could be guided by them. That was a third of our little force! And of what use to go out and be defeated, leaving the girls here to meet death almost immediately afterward?

We gathered at the porte. A last minute change made Grantline order six of his men to remain guarding the buildings. The instruments—the Erentz system—all the appliances had to be attended.

It left four platforms, each with three men, with Grantline at the controls of one of them. And upon the other two of the six Venza rode with Snap, and I with Anita.

We crouched in the shadows outside the porte. So small an army, sallying out to bomb this enemy vessel or be killed in the attempt! Only sixteen of us. And thirty or so brigands.

I envisaged then this tiny Moon-crater, the scene of this battle we were waging. Struggling humans, desperately trying to kill. Alone here on this globe. Around us, the wide reaches of Lunar desolation. In all this world, every human being was gathered here, struggling to kill!

Anita drew me down to the platform. "Ready, Gregg."

The others were rising. We lifted, moved slowly out and away from the protective shadows of the building.

In a tiny queue the six little platforms sailed out over the valley toward the brigand ship.

CHAPTER XXXVI
The Battle in the Crater

GRANTLINE led us. We held about level. Five hundred feet beneath us the brigand ship lay, cradled on the rocks. When it was still a mile away from us I could see all its outline fairly clearly in the dimness. Its tiny hull-windows were now dark; but the blurred shape of the hull was visible and above it the rounded cap of dome, with a dim radiance beneath it.

We followed Grantline's platform. It was rising, drawing the others after it like a tail. I touched Anita where she lay beside me with her head half in the small hooded control-bank.

"Going too high."

She nodded, but followed the line nevertheless. It was Grantline's command.

I lay crouched, holding the inner tips of the flexible side-shields. The bottom of the platform was covered with the insulated fabric. There were two side-shields. They extended upward some two feet, flexible so that I could hold them out to see over them, or draw them up and in to cover us.

They afforded a measure of protection against the hostile rays, though just how much we were not sure. With the platform level, a bolt from beneath could not harm us unless it continued for a considerable time. But the platform, except upon direct flight, was seldom level, for it was a frail, unstable little vehicle! To handle it was more than a question of the controls. We balanced, and helped to guide it, with the movement of our bodies—shifting our weight sidewise, or back, or forward to make it dip as the controls altered the gravity-pull in its tiny plate-sections.

Like a bird, wheeling, soaring, swooping. To me, it was a precarious business.

BUT now we were in straight flight diagonally upward. The outline of the brigand ship came under us. I crouched tense, breathless; every moment it seemed that the brigands must discover us and loose their bolts.

They may have seen us for some moments before they fired. I peered over the side-shield down at our mark, then up ahead to get Grantline's firing signal. It seemed long delayed. We were almost over the ship. An added glow down there must have warned Grantline that a shot was coming. The tiny red light flared bright on his platform.

I hissed on our Benson curve-light radiance. We had been dark, but a soft glow now enveloped us. Its sheen went down to the ship to reveal us. But its curving path showed us falsely placed. I saw the little line of platforms ahead of us seem to move suddenly sidewise.

It was everyone for himself now; none of us could tell where the other platforms actually were placed or headed. Anita swooped us sharply down to avoid a possible collision.

"Gregg—?"

"Yes. I'm aiming."

I was making ready to drop the little explosive globe-bomb. Our search-light ray at the camp, answering Grantline's signal, shot down and bathed the ship in a white glare, revealing it for our aim. Simultaneously the brigand bolts came up at us.

I held my bomb out over the shield, calculating the angle to throw it down. The brigand rays flashed around me. They were horribly close; Miko had understood our sudden visible shift and aimed, not where we appeared to be, but where we had been a moment before.

I DROPPED my bomb hastily at the glowing white ship. The touch of a hostile ray would have exploded it in my hand. I could see its blue-sizzling fuse as it fell. I saw the others also dropping from our nearby platforms. The explosions from them merged in a confusion of the white glare—and a cloud of black light-mist as the brigands out on the rocks used their occulting darkness bombs.

We swept past in a blur of leaping hostile beams. Silent battle of lights! Darkness bombs down at the ship struggling to bar our camp search-ray. The Benson radiance-rays from our passing platforms curving down to mingle with the confusion. The electronic rays sending up their bolts....

Our platforms dropped some ten dynamitrine bombs in that first passage over the ship. As we sped by, I dimmed the Benson's radiance. I peered. We had not hit the ship. Or if we had, the damage was inconclusive. But on the rocks I could see a pile of ore-carts scattered—broken wreckage, in which the litter of two or three projectors seemed strewn. And the gruesome deflated forms of several helmeted figures. Others seemed, to be running, scattering—hiding in the rocks and pit-holes. Twenty brigands at least were outside the ship. Some were running over toward the base of our camp-ledge. The darkness bombs were spreading like a curtain over the valley floor; but it seemed that some of the figures were dragging their projectors away.

We sailed off toward the opposite crater-rim. I remember passing over the broken wreckage of Grantline's little space-ship, the Comet. Miko's bolts momentarily had vanished. We had hit some of his outside projectors; the others were abandoned, or being dragged to safer positions.

AFTER a mile we wheeled and went back. I suddenly realized that only four platforms were in the re-formed line ahead of us. One was missing! I saw it now, wavering down, close over the ship. A bolt leaped up diagonally from a distant angle on the rocks and caught the disabled platform. It fell, whirling, glowing red—disappeared into the blur of darkness like a bit of heated metal plunged into water.

One out of six of our platforms already lost! Three men of our little force gone!

But Grantline led us desperately back. Anita caught his signal to break our line. The five platforms scattered, dipping and wheeling like frightened birds—blurring shapes, shifting unnaturally in flight as the Benson curve-angles were altered.

Anita now took our platform in a long swoop downward. Her tense, murmured voice sounded in my ears:

"Hold off: I'll take us low."

A melee. Passing platform shapes. The darting bolts, crossing like ancient rapiers. Falling blue points of fuse-lights as we threw our bombs.

Down in a swoop. Then rising. Away, and then back. This silent warfare of lights! It seemed that around me must be bursting a pandemonium of sound. Yet I heard nothing. Silent, blurred melee, infinitely frightening. A bolt struck us, clung for an instant; but we weathered it. The light was blinding. Through my gloves I could feel the tingle of the over-charged shield as it caught and absorbed the hostile bombardment. Under me the platform seemed heated. My little Erentz motors ran with ragged pulse. I got too much oxygen; my head roared with it. Spots danced before my closed eyes. Then not enough oxygen. I was dully smothering....

Then the bolt was gone. I found us soaring upward, horribly tilted. I shifted over.

"Anita! Anita, dear!"

"Yes. Gregg. All right."

THE melee went on. The brigand ship and all its vicinity was enveloped in darkness-mist now—a turgid sable curtain, made more dense by the dissipating heavy fumes of our exploding bombs which settled low over the ship and the rocks nearby. The search-light from our camp strove futilely to penetrate the cloud.

Our platforms were separated. One went by high over us; I saw another dart close beneath my shield.

"God, Anita!"

"Too close! I did not mean that—I didn't see it."

Almost a collision.

"Oh, Gregg, haven't we broken the ship's dome yet?"

It seemed not. I had dropped nearly all my bombs. This could not go on much longer. Had it been only five minutes? Only that? Reason told me so, yet it seemed an eternity of horror.

Another swoop. My last bomb. Anita had brought us into position to fling it. But I could not. A bolt stabbed up from the gloom and caught us. We huddled, pulling the shields up and over us.

Blurred darkness again. Too much to the side now. I had to wait while Anita swung us back. Then we seemed too high.

We swooped. But not too low! Down in the darkness-mist we would immediately have lost direction, and crashed.

I waited with my last bomb. The other platforms were occasionally dropping them: I had been too hasty, too prodigal.

Had we broken the ship's dome with a direct hit? It seemed not.

THE brigands were occasionally sending up catapulted light-flares. They came from positions on the rocks outside the ship. They mounted in lazy curves and burst over us. The concealing darkness, broken only by the flares of our explosions, enveloped the enemy. Our camp search-light was still struggling with it. But overhead, where the few little platforms were circling and swooping, the flares gave an almost continuous glare. It was dazzling, blinding. Even through the smoked pane which I adjusted to my visor I could not stand it.

But there were thoughts of comparative dimness. In a patch where the Earthlight struck through the darkness of the rocks, I saw another of our fallen platforms! Snap and Venza! Dear God....

It was not they, but three figures of our men. One was dead. Two had survived the fall. They stood up, staggering. And in that instant, before the turgid black curtain closed over them, I saw two brigands come rushing. Their hand projectors stabbed at close range. Our men crumpled and fell.

And now I saw why probably we had never yet hit the ship.

Its outline was revealed. "Now, Gregg—can you fling it from here?"

We were in position again. I flung my last missile, watched its light as it dropped. On the dome-roof two of Miko's men were crouching. My bomb was truly aimed—perhaps one of the few in all our bombardment which would have landed directly on the dome-roof. But the waiting marksmen fired at it with short-range heat projectors and exploded it harmlessly while it was still above them.

We swung up and away. I saw, high above us, Grantline's platform, recognizing its red signal light. There seemed a lull. The enemy fire had died down to only a very occasional bolt. In the confusion of my whirling impressions I wondered if Miko were in distress? Not that! We had not hit his ship; perhaps we had done little damage indeed! It was we who were in distress. Two of our platforms had fallen—two out of six. Or more, of which I did not know.

I SAW one rising off to the side of us. Grantline was over us. Well, we were at least three. And then I saw the fourth.

"Grantline is calling us up, Gregg."

"Yes."

Grantline's signal-light was summoning us from the attack. He was a thousand or two thousand feet above.

I was suddenly shocked with horror. The search-ray from our camp abruptly vanished! Anita wheeled us to face the distant ledge. The camp-lights showed, and over one of the buildings was a distress light!

Had the crack in our front wall broken, threatening explosion of all the buildings? The wild thoughts swept me. But it was not that. I could see light-stabs from the cliff outside the main building. Miko had dared to send some of his men to attack our almost abandoned camp!

Grantline realized it. His red helmet-light semaphored the command to follow him. His platform soared away, heading for the camp, with the other two behind him.

Anita lifted us to follow. But I checked her.

"No! Off to the right, across the valley."

"But Gregg!"

"Do as I say, Anita."

She swung us diagonally away from both the camp and the brigand ship. I prayed that we might not be noticed by the brigands.

"Anita, listen: I've an idea!"

The attack on the brigand ship was over. It lay enveloped in the darkness of the powder-gas cloud and its own darkness bombs. But it was uninjured.

Miko had answered us with our own tactics. He had practically unmanned the ship, no doubt, and had sent his men to our buildings. The fight had shifted. But I was now without ammunition, save for two or three small bullet projectors.

Of what use for our platform to rush back? Miko expected that. His attack on the camp was undoubtedly made just for that purpose.

"Anita, if we can get down on the rocks somewhere near the ship, and creep up on it unobserved in that blackness...."

I MIGHT be able to open its manual hull-lock, rip it open and let the air out. If I could get into its pressure chamber and unseal the inner slide....

"It would wreck the ship, Anita, exhaust all its air. Shall we try it?"

"Whatever you say, Gregg."

We seemed to be unobserved. We skimmed close to the valley floor, a mile from the ship. We headed slowly toward it, sailing low over the rocks.

Then we landed, left the platform.

"Let me go first, Anita."

I held a bullet projector. With slow, cautious leaps, we advanced. Anita was behind me. I had wanted to leave her with the platform, but she would not stay. And to be with me seemed at least equally safe.

The rocks were deserted. I thought there was very little chance that any of the enemy would lurk here. We clambered over the pitted, scarred surface. The higher crags, etched with Earthlight, stood like sentinels in the gloom.

The brigand ship with its surrounding darkness was not far from us. Then we entered the cloud.

No one was out here. We passed the wreckage of broken projectors, and gruesome, shattered human forms.

We prowled closer. The hull of the ship loomed ahead of us. All dark.

We came at last close against the sleek metal hull-side, slid along it toward where I was sure the manual-porte was located.

Abruptly I realized that Anita was not behind me! Then I saw her at a little distance, struggling in the grip of a giant helmeted figure! The brigand lifted her—turned, and, carrying her, ran the other way!

I did not dare fire. I bounded after them along the hull-side, around under the curve of the pointed bow, down along the other side.

I had mistaken the hull-porte location. It was here. The running, bounding figure reached it, slid the panel. I was only fifty feet away—not much more than a single leap. I saw Anita being shoved into the pressure lock. The Martian flung himself after her.

I fired at him, but missed. I came with a rush. And as I reached the porte it slid closed in my face, barring me!

CHAPTER XXXVII
In the Pressure Lock.

WITH puny fists I pounded the panel. A small pane in it was transparent. Within the lock I could see the blurred figures of Anita and her captor—and, it seemed, another figure. The lock was some ten feet square, with a low ceiling. It glowed with a dim tube-light.

I pounded, thumped with futile, silent blows. The mechanism was here to open this manual; but it was now clasped from within and would not operate.

A few seconds only, while I stood there in a panic of confusion, raging to get in. This disaster had come so suddenly! I did not plan; I had no thought save to batter my way in and rescue Anita. I recall that I beat on the glassite pane with my bullet projector until the weapon was bent and useless; and I flung it with a wild, despairing rage at my feet.

They were letting the ship's air-pressure into this lock. Soon they would open the inner panel, step into the secondary chamber—and in a moment more would be within the ship's hull corridor. Anita, lost to me!

The outer panel suddenly opened! I had lunged against it with my shoulder; the giant figure inside slid it. I was taken by surprise! I half-fell inward.

Huge arms went around me. The goggled face of the helmet peered into mine.

"So it is you, Haljan! I thought I recognized that little device over your helmet-bracket. And there is my little Anita, come back to me again!"

Miko!

THIS was he. His great bloated arms encircling me, bending me backward, holding me almost helpless. I saw over his shoulder that Anita was clutched in the grip of another helmeted figure. No giant, but tall for an Earthman—almost as tall as myself. Then the tube-light in the room illumined the visor. I saw the face, recognized it. Moa!

I gasped, "So—I've—got you, Miko—"

"Got me! You're a fool to the last, Gregg Haljan! A fool to the last! But you were always a fool."

I could scarcely move in his grip. My arms were pinned. As he slowly bent me backward, I wound my legs around one of his; it was as unyielding as a steel pillar. He had closed the outer panel; the air-pressure in the lock was rising. I could feel it against my suit.

My helmeted head was being forced backward; Miko's left arm held me. In his gloved right hand as it came slowly up over my throat I saw a knife-blade, its naked, sharpened metal glistening blue-white in the light from overhead.

I seized his wrist. But my puny strength could not hold him. The knife, against all my efforts, came slowly down.

A moment of this slow deadly combat—the end of everything for me.

I was aware of the helmeted figure of Moa casting off Anita—and then the two girls leaping together upon Miko. It threw him off his balance, and my hanging weight made him topple forward. He took a step to recover himself; his hand with the knife was flung up with an instinctive, involuntary balancing gesture. And as it came swiftly down again, I forced the knife-blade to graze his throat. Its point caught in the fabric of his suit.

His startled oath jangled in my ears. The girls were clawing at him; we were all four scrambling, swaying. With despairing strength I twisted at his waist. The knife went into his throat. I plunged it deeper.

HIS suit went flabby. He crumpled over me and fell, knocking me to the floor. His voice, with the horrible gurgling rasp of death in it, rattled my ear-grids.

"Not such a fool—are you, Haljan—"

Moa's helmeted head was close over us. I saw that she had seized the knife, jerked it from her brother's throat. She leaped backward, waving it.

I twisted from under Miko's inert, lifeless body. As I got to my feet, Anita flung herself to shield me. Moa was across the lock, backed up against its wall. The knife in her hand went up. She stood for the briefest instant regarding Anita and me holding each other. I thought that she was about to leap upon us; but before I could move, the knife came down and plunged into her breast. She fell forward, her grotesque helmet striking the floor-grid almost at my feet.

"Gregg!"

"She's dead."

"No! She moved! Get her helmet off! There's enough air here."

My helmet pressure-indicator was faintly buzzing to show that a safe pressure was in the room. I shut off Moa's Erentz motors, unfastened her helmet, raised it off. We gently turned her body. She lay with closed eyes, her pallid face blue-cast from the light in the lock.

With our own helmets off, we knelt over her.

"Oh. Gregg, is she dead?"

"No. Not quite—but dying."

"Oh Gregg, I don't want her to die! She was trying to help you there at the last."

She opened her eyes; the film of death was glazing them. But she saw me, recognized me.

"Gregg—"

"Yes, Moa, I'm here."

HER livid lips were faintly drawn in a smile. "I'm—so glad—you took the helmets off, Gregg. I'm—going—you know."

"No!"

"Going—back to Mars—to rest with the fire-makers—where I came from. I was thinking—maybe you would kiss me, Gregg—?"

Anita gently pushed me down. I pressed the white, faintly smiling lips with mine. She sighed, and it ended with a rattle in her throat.

"Thank you—Gregg—closer—I can't talk so loudly—"

One of her gloved hands struggled to touch me, but she had no strength and it fell back. Her words were the faintest of whispers:

"There was no use living—without your love. But I want you to see—now—that a Martian girl can—die with a smile—"

Her eyelids fluttered down: it seemed that she sighed and then was not breathing. But on her livid face the faint smile still lingered to show me how a Martian girl could die.

We had forgotten for the moment where we were. As I glanced up I saw that through the inner panel, past the secondary lock, the ship's hull-corridor was visible, and along its length a group of Martians were advancing! They saw us, and came running.

"Anita! Look! We've got to get out of here!"

The secondary lock was open to the corridor. We jammed on our helmets. The unhelmeted brigands by then were fumbling at the inner panel. I pulled at the lever of the outer panel. The brigands were hurrying, thinking they could be in time to stop me. One of the more cautious fumbled with a helmet.

"Anita, run! Try and keep your feet."

I slid the outer panel and pushed at Anita. Simultaneously the brigands opened the inner porte.

The air came with a tempestuous rush. A blast through the inner porte—through the little pressure-lock—a wild rush out to the airless Moon. All the air in the ship madly rushing to escape....

Like feathers we were blown with it. I recall an impression of the hurtling brigand figures and swift-flying rocks under me. A silent crash as I struck.

Then soundless, empty blackness.

CHAPTER XXXVIII
Triumph!

"Is he conscious? We'd better take him back, get his helmet off."

"It's over. We can get back now. Venza, dear, we've won—it's over."

"He hears us!"

"Gregg!"

"He hears us—he's all right!"

I opened my eyes. I lay on the rocks. Over my helmet other helmets were peering, and faint, familiar voices mingled with the roaring in my ears.

"—back to the camp and get his helmet off."

"Are his motors smooth? Keep them right, Snap—he must have good air."

I seemed unhurt. But Anita....

She was here. "Gregg, dear one!"

Anita safe! All four of us here on the Earthlit rocks, close outside the brigand ship.

"Anita!"

She held me, lifted me. I was uninjured. I could stand; I staggered up and stood swaying. The brigand ship, a hundred feet away, loomed dark and silent, a lifeless bulk, already empty of air, drained in that mad blast outward. Like the wreck of the Planetara—a dead, pulseless hulk already.

We four stood together, triumphant. The battle was over. The brigands were worsted, almost the last man of them dead or dying. No more than ten or fifteen had been available for that final assault upon the camp buildings. Miko's last strategy. I think perhaps he had intended, with his few remaining men, to take the ship and make away, deserting his fellows.

All on the ship, caught unhelmeted by the explosion, were dead long since.

I stood listening to Snap's triumphant account. It had not been difficult for the flying platforms to hunt down the attacking brigands on the open rocks. We had only lost one more platform.

Human hearts beat sometimes with very selfish emotions. It was a triumphant ending for us, and we hardly gave a thought that half of Grantline's little group had perished.

We huddled on Snap's platform. It rose, lurching drunkenly, barely carrying us.

And as we headed for the Grantline buildings, where still the rift in the wall had not quite broken, there came the final triumph. Miko had been aware of it, and knew he had lost. Grantline's search-light leaped upward, swept the sky, caught its sought-for object—a huge silver cylinder, bathed brightly in the white search-beam glare.

The police-ship from Earth!

CHAPTER XXXIX
My Exit

MY narrative lies now in this permanently recorded form before you, and I prepare my exit bow with the humble hope that I may have given you pleasure. If so, I do beg you to tell me of it. There are some who already have flashed their approval of my discs; I thank them most earnestly and gratefully.

My errors of recording unquestionably are many; and for them I ask your indulgence. There have been, I can readily see, errors of omission. I have not mentioned, for instance, the final rescue of the Planetara's marooned passengers on the asteroid. You will bear with me, since the disc-space has its technical limitations, that such omissions have been unavoidable.

Since the passage of the Earth-law by the Federated Board of Education, forcing narrative fiction to cling so closely to sworn facts of actual happening, I need offer no assurance of the truth of my narrative. My witnesses have filed their corroborating declarations. Indeed, the Planetara's wreck and the brigands' attack upon the Moon-treasure were given the widest news-casters' publicity, as you all know. Yet I, who was unwittingly involved in those stirring events, may have added a more personal note, making the scenes more vivid to your imagination. I have tried to do that. I do hope that in some measure you will think I have succeeded.

There are many foolish girls now who say that they would like to know Gregg Haljan. They doubtless would be very disappointed. I really crave no more publicity. And the girls of all the Universe have no charm for me. There is only one, for me—an Earth-girl.

I think that life has very beautifully endowed me with its blessings.
