+
+
+<p>The sun was glowing dull red as it slipped down behind the curving
+horizon of Mars, but Gregory Hunter was not able to see it.</p>
+
+<p>There was no viewscreen in the ship's cabin; it was too tiny for that.
+Greg twisted around in the cockpit that had been built just big enough
+to hold him, and shifted his long legs against the brace-webbing, trying
+to get them comfortable.</p>
+
+<p>He knew he was afraid ... but nobody else knew that, not even the
+captain waiting at the control board on the satellite, and in spite of
+the fear Greg Hunter would not have traded places at this moment with
+anyone else in the universe.</p>
+
+<p>He had worked too hard and waited too long for this moment.</p>
+
+<p>He heard the count-down monitor clicking in his ears, and his hands
+clenched into fists. How far from Mars would he be ten minutes from now?
+He didn't know. Farther than any man had ever traveled before in the
+space of ten minutes, he knew, and faster. How far and how fast would
+depend on him alone.</p>
+
+<p>"All set, Greg?" It was the captain's voice in the earphones.</p>
+
+<p>"All set, Captain."</p>
+
+<p>"You understand the program?"</p>
+
+<p>Greg nodded. "Twenty-four hours out, twenty-four hours back, ninety
+degrees to the ecliptic, and all the accelleration I can stand both
+ways."</p>
+
+<p>Greg grinned to himself. He thought of the months of conditioning he had
+gone through to prepare for this run ... the hours in the centrifuge to
+build up his tolerance to accelleration, the careful diet, the rigorous
+hours of physical conditioning. It was only one experiment, one tiny
+step in the work that could someday give men the stars, but to Gregory
+Hunter at this moment it was everything.</p>
+
+<p>"Good luck, then." The captain cut off, and the blastoff buzzer sounded.</p>
+
+<p>He was off. His heart hammered in his throat, and his eyes ached
+fiercely, but he paid no attention. His finger crept to the air-speed
+indicator, then to the cut-off switch. When the pressure became too
+great, when he began to black out, he would press it.</p>
+
+<p>But not yet. It was speed they wanted; they had to know how much
+accelleration a man could take for how long and still survive, and now
+it was up to him to show them.</p>
+
+<p>Fleetingly, he thought of Tom ... poor old stick-in-the-mud Tom, working
+away in his grubby little Mars-bound laboratory, watching bacteria grow.
+Tom could never have qualified for a job like this. Tom couldn't even go
+into free-fall for ten minutes without getting sick all over the place.
+Greg felt a surge of pity for his brother, and then a twinge of
+malicious anticipation. Wait until Tom heard the reports on <i>this</i> run!
+It was all right to spend your time poking around with bottles and test
+tubes if you couldn't do anything else, but it took something special to
+pilot an XP ship for Project Star-Jump. And after this run was over,
+even Tom would have to admit it....</p>
+
+<p>There was a lurch, and quite suddenly the enormous pressure was gone.</p>
+
+<p>Something was wrong. He hadn't pushed the cut-off button, yet the ship's
+engines were suddenly silent. He jabbed at the power switch. Nothing
+happened. Then the side-jets sputted, and he was slammed sideways into
+the cot.</p>
+
+<p>He snapped on the radio speaker. "Control ... can you hear me?
+Something's gone wrong out here...."</p>
+
+<p>"Nothing's wrong," the captain's voice said in his earphones. "Just sit
+tight. I'm bringing you back in. There's a call here from Sun Lake City.
+They want you down there in a hurry. We'll have to scratch you on this
+run."</p>
+
+<p>"<i>Who</i> wants me down there?"</p>
+
+<p>"The U.N. Council office. Signed by Major Briarton himself and I can't
+argue with the Major. We're bringing you in."</p>
+
+<p>Greg Hunter sank back, disappointment so thick he could taste it in his
+mouth. Sun Lake City! That meant two days at least, one down, one back,
+maybe more if connections weren't right. It meant that the captain would
+send Morton or one of the others out in his place. It meant....</p>
+
+<p>Suddenly he thought of what else it meant, and a chill ran up his back.</p>
+
+<p>There was only one reason Major Briarton would call him in like this.
+Something had happened to Dad.</p>
+
+<p>Greg leaned back in the cot, suddenly tense, as a thousand frightful
+possibilities flooded his mind. It could only mean that Dad was in some
+kind of trouble.</p>
+
+<p>And if anything had happened to Dad....</p>
+
+<hr style='width: 45%;' />
+
+<p>The sun was sinking rapidly toward the horizon when the city finally
+came into sight in the distance, but try as he would, Tom Hunter could
+not urge more than thirty-five miles an hour from the huge lurching
+vehicle he was driving.</p>
+
+<p>On an open paved highway the big pillow-wheeled Sloppy Joe would do
+sixty in a breeze, but this desert route was far from a paved road.
+Inside the pressurized passenger cab, Tom gripped the shock-bars with
+one arm and the other leg, and jammed the accelerator to the floor. The
+engine coughed, but thirty-five was all it would do.</p>
+
+<p>Through the windshield Tom could see the endless rolling dunes of the
+Martian desert stretching to the horizon on every side. They called Mars
+the Red Planet, but it was not red when you were close to it. There were
+multitudes of colors here ... yellow, orange, brown, gray, occasional
+patches of gray-green ... all shifting and changing in the fading
+sunlight. Off to the right were the worn-down peaks of the Mesabi II,
+one of the long, low mountain ranges of almost pure iron ore that helped
+give the planet its dull red appearance from outer space. And behind
+him, near the horizon, the tiny sun glowed orange out of a blue-black
+sky.</p>
+
+<p>Tom fought the wheel as the Sloppy Joe jounced across a dry creek bed,
+and swore softly to himself. Why hadn't he kept his head and waited for
+the mail ship that had been due at the Lab to give him a lift back? He'd
+have been in Sun Lake City an hour ago ... but the urgency of the
+message had driven caution from his mind.</p>
+
+<p>A summons from the Mars Coordinator of the U.N. Interplanetary Council
+was the same as an order ... but there was more to Tom's haste than
+that. There was only one reason that Major Briarton would be calling him
+in to Sun Lake City, and that reason meant trouble.</p>
+
+<p>Something was wrong. Something had happened to Dad.</p>
+
+<p>Now Tom peered up at the dark sky, squinting into the sun. Somewhere out
+there between Mars and Jupiter was a no-man's-land of danger, a great
+circling ring of space dirt and debris, the Asteroid belt. And somewhere
+out there, Dad was working.</p>
+
+<p>Tom thought for a moment of the pitiful little mining rig that Roger
+Hunter had taken out to the Belt ... the tiny orbit-ship to be used for
+headquarters and storage of the ore; the even tinier scout ship, Pete
+Racely's old <i>Scavenger</i> that he had sold to Roger Hunter for back taxes
+and repairs when he went broke in the Belt looking for his Big Strike.
+It wasn't much of a mining rig for anybody to use, and the dangers of a
+small mining operation in the Asteroid Belt were frightening. It took
+skill to bring a little scout-ship in for a landing on an asteroid rock
+hardly bigger than the ship itself; it took even more skill to rig the
+controlled-Murexide charges to blast the rock into tiny fragments, and
+then run out the shiny magnetic net to catch the explosion debris and
+bring it in to the hold of the orbit-ship....</p>
+
+<p>Tom Hunter scowled, trying to shake off the feeling of uneasiness that
+was nibbling at his mind. Asteroid mining was dangerous ... but Dad was
+no novice. Nobody on Mars knew how to handle a mining rig better than
+Roger Hunter did. He knew what he was doing out there, there was no real
+danger for him or was there....</p>
+
+<p>Roger Hunter, a good man, a gentle and peaceful man, had finally seen
+all he could stomach of Jupiter Equilateral and its company mining
+policies six months before. He had told them so in plain, simple
+language when he turned in his resignation. They didn't try to stop
+him ... a man was still free to quit a job on Mars if he wanted to, even
+a job with Jupiter Equilateral. But it was an open secret that the big
+mining outfit had not liked Roger Hunter's way of resigning, taking half
+a dozen of their first-rate mining engineers with him. There had been
+veiled threats, rumors of attempts to close the markets to Roger
+Hunter's ore, in open violation of U.N. Council policies on Mars....</p>
+
+<p>Tom fought the wheel as the big tractor lumbered up another rise, and
+the huge plastic bubble of Sun Lake City came into view far down the
+valley below.</p>
+
+<p>He thought of Greg. Had Greg been summoned too? He closed his lips
+tightly as a wave of anger passed through his mind. If anything had
+happened, no matter what, he thought, Greg would be there. Taking over
+and running things, as usual. He thought of the last time he had seen
+his brother, and then deliberately blocked out the engulfing bitterness.</p>
+
+<p>That had been more than a year ago. Maybe Greg had changed since then.</p>
+
+<p>But somehow, Tom didn't think so.</p>
+
+<p>The Sloppy Joe was on the valley floor now, and ahead the bubble
+covering the city was drawing closer. The sun was almost gone; lights
+were appearing inside the plastic shielding. Born and raised on Mars,
+Tom had seen the teeming cities of Earth only once in his life ... but
+to him none of the splendors of the Earth cities could match the simple,
+quiet beauty of this Martian outpost settlement. There had been a time
+when people had said that Sun Lake City could never be built, that it
+could never survive if it were, but with each successive year it grew
+larger and stronger, the headquarters city for the planet that had
+become the new frontier of Earth.</p>
+
+<p>The radiophone buzzed, and the airlock guard hailed him when he returned
+the signal. Tom gave his routine ID. He guided the tractor into the
+lock, waited until pressure and atmosphere rose to normal, and then
+leaped out of the cab.</p>
+
+<p>Five minutes later he was walking across the lobby of the Interplanetary
+Council building, stepping into the down elevator. Three flights below
+he stepped out into the office corridor of the U.N. Interplanetary
+Council on Mars.</p>
+
+<p>If there was trouble, this was where he would find it.</p>
+
+<p>He paused for a minute before the gray plastic door marked MAJOR FRANK
+BRIARTON in raised stainless steel letters. Then he pushed open the door
+and walked into the ante-room.</p>
+
+<p>It was empty. Suddenly he felt a touch on his shoulder. Behind him, a
+familiar voice said, "Hello, Twin."</p>
+
+<hr style='width: 45%;' />
+
+<p>At first glance they looked like carbon copies of each other, although
+they were no more identical than identical twins ever are. Greg stood a
+good two inches taller than Tom. His shoulders were broad, and there was
+a small gray scar over one eye that stood out in contrast to the healthy
+tanned color of his face. Tom was of slighter build, and wirier, his
+skin much more pale.</p>
+
+<p>But they had the same dark hair, the same gray eyes, the same square,
+stubborn line to the jaw. They looked at each other for a moment without
+speaking. Then Greg grinned and clapped his brother on the shoulder.</p>
+
+<p>"So you got here, finally," he said. "I was beginning to think I'd have
+to go out on the desert and find you."</p>
+
+<p>"Oh, I got here, all right," Tom said. "I see you did too."</p>
+
+<p>"Yes," Greg said heavily. "Can't argue with the major, you know."</p>
+
+<p>"But what does he want?"</p>
+
+<p>"How should I know? All he said was to get down here fast. And now he
+isn't even here himself."</p>
+
+<p>"Is Dad on Mars?" Tom asked.</p>
+
+<p>Greg looked at him. "I don't know."</p>
+
+<p>"We could check the register."</p>
+
+<p>"I already checked it. He has not logged in, but that doesn't mean
+anything."</p>
+
+<p>"I suppose not," Tom said glumly.</p>
+
+<p>They were silent for a moment. Then Greg said, "Look, what are you
+worried about? Nothing could have happened to Dad. He's been mining the
+Belt for years."</p>
+
+<p>"I know. I just wish he were here, that's all. If he's in some kind of
+trouble...."</p>
+
+<p>"What kind of trouble? You're looking for spooks."</p>
+
+<p>"Spooks like Jupiter Equilateral, maybe," Tom said. "They could make
+plenty of trouble for Dad."</p>
+
+<p>"With the U.N. in the driver's seat here? They wouldn't dare. Why do you
+think the major rides them so hard with all the claim-filing
+regulations? He'd give his right arm for a chance to break that outfit
+into pieces."</p>
+
+<p>"I still wish somebody had gone out to the Belt with Dad," Tom said.</p>
+
+<p>Just then the door opened. The newcomer was a tall, gray-haired man with
+U.N. Council stripes on his lapel, and major's rockets on his shoulders.
+"Sorry I'm late, boys," Major Briarton said. "I'd hoped to be here when
+you arrived. I'm sorry to pull you in here like this, but I'm afraid I
+had no choice. When did you boys hear from your father last?"</p>
+
+<p>They looked at each other. "I saw him six weeks ago," Tom said. "Just
+before he left to go out to the Belt again."</p>
+
+<p>"Nothing since then?"</p>
+
+<p>"Not a word."</p>
+
+<p>The major chewed his lip. "Greg?"</p>
+
+<p>"I had a note at Christmas, I think. But what...."</p>
+
+<p>"What did he say in the note?"</p>
+
+<p>"He said Merry Christmas and Happy New Year. Dad isn't much of a letter
+writer."</p>
+
+<p>"Nothing at all about what he was doing?"</p>
+
+<p>Greg shook his head. "Look, Major, if there's some sort of trouble...."</p>
+
+<p>"Yes, I'm afraid there's trouble," the major said. He looked up at them,
+and spread his hands helplessly. "There isn't any easy way to tell you,
+but you've got to know. There's been an accident, out in the Belt."</p>
+
+<p>"Accident?" Greg said.</p>
+
+<p>"A very serious accident. A fuel tank exploded in the scooter your
+father was riding back to the <i>Scavenger</i>. It must have been very
+sudden, and by the time help arrived...." The major broke off, unable to
+find words.</p>
+
+<p>For a long moment there was utter silence in the room. Outside, an
+elevator was buzzing, and a typewriter clicked monotonously somewhere in
+the building.</p>
+
+<p>Then Tom Hunter broke the silence. "Who was it, Major?" he said. "Who
+killed Dad? Tell us, or we'll find out!"</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="c2_Jupiter_Equilateral" id="c2_Jupiter_Equilateral"></a>2. Jupiter Equilateral</h2>
+
+
+<p>For a moment, Major Briarton just stared at him. Then he was on his
+feet, shaking his head as he came around the desk. "Tom, use your head,"
+he said. "It's as much of a shock to me as it is to you, but you can't
+afford to jump to false conclusions...."</p>
+
+<p>Tom Hunter looked up bitterly. "He's dead, isn't he?"</p>
+
+<p>"Yes, he's dead. He must have died the instant of the explosion...."</p>
+
+<p>"You mean you don't know?"</p>
+
+<p>"I wasn't there at the time it happened, no."</p>
+
+<p>"Then who was?"</p>
+
+<hr style='width: 45%;' />
+
+<p>Major Briarton spread his hands helplessly. "Nobody was. Your father was
+alone. From what we could tell later, he'd left the <i>Scavenger</i> to land
+on one of his claims, using the ship's scooter for the landing. He was
+on the way back to the <i>Scavenger</i> when the rear tank exploded. There
+wasn't enough left of it to tell what went wrong ... but it was an
+accident, there was no evidence to suggest anything else."</p>
+
+<p>Tom looked at him. "You really believe that?"</p>
+
+<p>"I can only tell you what we found."</p>
+
+<p>"Well, I don't believe it for a minute," Tom said angrily. "How long
+have you and Dad been friends? Twenty years? Twenty-five? Do you really
+think Dad would have an accident with a mining rig?"</p>
+
+<p>"I know he was an expert engineer," the major said. "But things can
+happen that even an expert can't foresee, mining in the Belt."</p>
+
+<p>"Things like a fuel tank exploding? Not to Dad, they would never happen.
+I don't care what anybody says...."</p>
+
+<p>"Easy, Tom," Greg said.</p>
+
+<p>"Well, I won't take it easy. Dad was too careful for something like that
+to happen. If he had an accident, somebody <i>made</i> it happen."</p>
+
+<p>Greg turned to the major. "What was Dad doing out there?"</p>
+
+<p>"Mining."</p>
+
+<p>"By himself? No crew at all?"</p>
+
+<p>"No, he was alone."</p>
+
+<p>"I thought the regulations said there always had to be at least two men
+working an asteroid claim."</p>
+
+<p>"That's right. Your father had Johnny Coombs with him when he left Sun
+Lake City. They signed out as a team ... and then Johnny came back to
+Mars on the first shuttle ship."</p>
+
+<p>"How come?"</p>
+
+<p>"Not even Johnny knows. Your father just sent him back, and there was
+nothing we could do about it then. The U.N. has no jurisdiction in the
+belt, unless a major crime has been committed." Major Briarton shook his
+head helplessly. "If a man is determined to mine a claim all by himself
+out there, he can find a dozen different ways to wiggle out of the
+regulations."</p>
+
+<p>"But Dad would never be that stupid," Greg said. "If he was alone when
+it happened, who found him?"</p>
+
+<p>"A routine U.N. Patrol ship. When Roger failed to check in at the
+regular eight-hour signal, they went out to see what was wrong. But by
+the time they reached him, it was too late to help."</p>
+
+<p>"I just don't get it," Greg said. "Dad had more sense than to try to
+mine out there all by himself."</p>
+
+<p>"I know," the major said. "I don't know the answer. I had the Patrol
+ship go over the scene of the accident with a comb after they found what
+had happened, but there was nothing there to find. It was an accident,
+and that's that."</p>
+
+<p>"What about Jupiter Equilateral?" Tom said hotly. "Everybody knows they
+were out to get Dad ... why don't you find out what <i>they</i> were doing
+when it happened, bring them in for questioning...."</p>
+
+<p>"I can't do that, I haven't a scrap of evidence," the major said
+wearily.</p>
+
+<p>"Why can't you? You're the Mars Coordinator, aren't you? You act like
+you're scared of them."</p>
+
+<p>Major Briarton's lips tightened angrily. "All right, since you put it
+that way ... I <i>am</i> scared of them. They're big, and they're powerful.
+If they had their way, there wouldn't be any United Nations control on
+Mars, there wouldn't be <i>anybody</i> to fight them and keep them in check.
+There wouldn't be any independent miners out in the Belt, either,
+because they'd all be bought out or dead, and Earth would pay through
+the nose for every ounce of metal that they got from the Asteroid Belt.
+That company has been trying to drive the U.N. off Mars for thirty
+years, and they've come so close to it that it scares me plenty." He
+pushed his chair back sharply and rose to his feet. "And that is
+exactly why I refuse to stir up a mess over this thing, unhappy as
+it is, without something more than suspicions and rumors to back me
+up ... because all Jupiter Equilateral needs is one big issue to make us
+look like fools out here, and we're through."</p>
+
+<p>He crossed the room to a wall cabinet, opened it, and pulled out a
+scarred aluminum box. "We found this in the cabin of the <i>Scavenger</i>. I
+thought you boys might want it."</p>
+
+<p>They both recognized it instantly ... the battered old spacer's pack
+that Roger Hunter had used for as long as they could remember. It seemed
+to them, suddenly, as if a part of him had appeared here in the room
+with them. Greg looked at the box and turned away. "You open it," he
+said to Tom in a sick voice.</p>
+
+<p>There was nothing much inside ... some clothing, a pipe and tobacco
+pouch, a jack knife, half a dozen other items so familiar that Tom could
+hardly bear to touch them. At the bottom of the pack was the heavy
+leather gun case which had always held Roger Hunter's ancient .44
+revolver. Tom dropped it back without even opening the flap. He closed
+the box and took a deep breath. "Then you really believe that it was an
+accident and nothing more?" he said to the major.</p>
+
+<p>Major Briarton shook his head. "What I think or don't think doesn't make
+any difference. It just doesn't matter. In order to do anything, I've
+got to have evidence, and there just isn't any evidence. I can't even
+take a ship out there for a second look, with the evidence I have, and
+that's all there is to it."</p>
+
+<p>"But you think that maybe it wasn't an accident, just the same," Tom
+pursued.</p>
+
+<p>The major hesitated. Then he shook his head again. "I'm sorry, but I've
+got to stand on what I've said. And I think you'd better stand on it,
+too. There's nothing else to be done."</p>
+
+<hr style='width: 45%;' />
+
+<p>It should have been enough, but it wasn't. As Tom Hunter walked with his
+brother down the broad Upper Ramp to the business section of Sun Lake
+City, he could not shake off the feeling of helpless anger, the growing
+conviction that Roger Hunter's death involved something more than the
+tragic accident in space that Major Briarton had insisted it was.</p>
+
+<p>"He didn't tell us everything he knew," Tom said fiercely. "He didn't
+say everything he wanted to say, either. He doesn't think it was an
+accident any more than I do."</p>
+
+<p>"How do you know, are you a mind reader?"</p>
+
+<p>"No."</p>
+
+<p>"Well, Dad wasn't a superman, either. He was taking an awful risk,
+trying to work a mining rig by himself, and he had a bad break. Why do
+you have to have somebody to blame for it?"</p>
+
+<p>"Keep talking," Tom said. "You'll convince yourself yet."</p>
+
+<p>Greg just jammed his hands in his pockets, and they walked in silence
+for a moment.</p>
+
+<p>For Tom and Greg Hunter, Sun Lake City had always been home. Now they
+walked along the Main Concourse, Tom with the aluminum box under his
+arm, Greg with his own spacer's pack thrown over his shoulder. They
+didn't talk; rather than being drawn closer by the news of the tragedy,
+it seemed that they had drawn farther apart, as though the one common
+link that had held them together had suddenly been broken.</p>
+
+<p>Finally Tom broke the silence. "At least there's one thing we can do,"
+he said. "I'm going to call Johnny Coombs."</p>
+
+<p>He shortly found a phone booth and dialed a number. Johnny had been a
+friend of the family for years; he and Roger Hunter had been partners in
+many mining ventures in the Asteroid Belt before Roger had taken his
+position with Jupiter Equilateral. If Johnny had any suspicions that
+Roger Hunter's accident had been more than an accident, he certainly
+would not hesitate to voice them....</p>
+
+<p>After a dozen rings, Tom hung up, tried another number. There was no
+answer there, either. Frowning, Tom rang the city's central paging
+system. "Put in a personal call for Johnny Coombs," he said when the
+"record" signal flashed on. "Tell him to contact the Hunters when he
+comes in. We'll be at home...."</p>
+
+<p>They resumed their silent walk. When they reached H wing on the fourth
+level, they turned right down an apartment corridor, and stopped in
+front of a familiar doorway. Tom pressed his palm against the
+lock-plate, and the door swung open.</p>
+
+<p>It was home to them, the only home they had ever known. Soft lights
+sprang up on the walls of the apartment as the door opened. Tom saw the
+old bookcases lining the walls, the drafting-board and light at the far
+end of the room, the simple chairs and dining table, the door which led
+into the bedroom and kitchen beyond. The room had the slightly
+disheveled look that it had had ever since Mom had died ... a slipper on
+the floor here, a book face down on the couch there....</p>
+
+<p>It looked as though Dad had just stepped out for an hour or so.</p>
+
+<p>Tom was three steps into the room before he saw the visitor.</p>
+
+<p>The man was sitting comfortably in Roger Hunter's easy chair, a short,
+fat man with round pink cheeks that sagged a little and a double chin
+that rested on his neck scarf. There were two other men in the room,
+both large and broad-shouldered; one of them nodded to the fat man, and
+moved to stand between the boys and the door.</p>
+
+<p>The fat man was out of his seat before the boys could speak, smiling at
+them and holding out his hand. "I wanted to be sure to see you before
+you left the city," he was saying, "so we just came on in to wait. I
+hope you don't mind our ... butting in, so to speak." He chuckled,
+looking from one twin to the other. "You don't know me, I suppose. I'm
+Merrill Tawney. Representing Jupiter Equilateral, you know."</p>
+
+<p>Tom took the card he was holding out, looked at the name and the tiny
+gold symbol in the corner, a letter "J" in the center of a triangle. He
+handed the card to Greg. "I've seen you before," he told the fat man.
+"What do you want with us?"</p>
+
+<p>Tawney smiled again, spreading his hands. "We've heard about the
+tragedy, of course. A shocking thing ... Roger was one of our group so
+recently. We wanted you to know that if there is anything at all we can
+do to help, we'd be only too glad...."</p>
+
+<p>"Thanks," Greg said. "But we're doing just fine."</p>
+
+<p>Tawney's smile tightened a little, but he hung onto it. "I always felt
+close to your father," he said. "All of us at Jupiter Equilateral did.
+We were all sorry to see him leave."</p>
+
+<p>"I bet you were," Greg said, "he was the best mining engineer you ever
+had. But Dad could never stand liars, or crooked ways of doing
+business."</p>
+
+<p>One of the men started for Greg, but the fat man stopped him with a wave
+of his hand. "We had our differences of opinion," he said. "We saw
+things one way, your father saw them another way. But he was a fine man,
+one of the finest...."</p>
+
+<p>"Look, Mr. Tawney, you'd better say what you came to say and get out of
+here," Greg said dangerously, "before we give your friends here
+something to do."</p>
+
+<p>"I merely came to offer you some help," Tawney said. He was no longer
+smiling. "Since your father's death, you two have acquired certain
+responsibilities. I thought we might relieve you of some of them."</p>
+
+<p>"What sort of responsibilities?"</p>
+
+<p>"You have an unmanned orbit-ship which is now a derelict in the Asteroid
+Belt. You have a scout-ship out there also. You can't just leave them
+there as a navigation hazard to every ship traveling in the sector.
+There are also a few mining claims which aren't going to be of much
+value to you now."</p>
+
+<p>"I see," Greg said. "Are you offering to buy Dad's mining rig?"</p>
+
+<p>"Well, I doubt very much that we'd have any use for it, as such. But we
+could save you the trouble of going out there to haul it in."</p>
+
+<p>"That's very thoughtful," Greg said. "How much are you offering?"</p>
+
+<p>Tom looked up in alarm. "Wait a minute," he said. "That rig's not for
+sale...."</p>
+
+<p>"How much?" Greg repeated.</p>
+
+<p>"Forty thousand dollars," Merrill Tawney said. "Ship, rig and claims.
+We'll even pay the transfer tax."</p>
+
+<p>Tom stared at the man, wondering if he had heard right. He knew what
+Roger Hunter had paid for the rig; he had been with Dad when the papers
+were signed. Tawney's offer was three times as much as the rig was
+worth.</p>
+
+<p>But Greg was shaking his head. "I don't think we could sell at that
+price."</p>
+
+<p>The fat man's hands fluttered. "You understand that those ships are
+hardly suited to a major mining operation like ours," he said, "and the
+claims...." He dismissed them with a wave of his hand. "Still, we'd want
+you to be happy with the price. Say, forty-five thousand?"</p>
+
+<p>Greg hesitated, shook his head again. "I guess we'd better think it
+over, Mr. Tawney."</p>
+
+<p>"Fifty thousand is absolutely the top," Tawney said sharply. "I have the
+papers right here, drawn up for your signatures, but I'm afraid we can't
+hold the offer open."</p>
+
+<p>"I don't know, we might want to do some mining ourselves," Greg said.
+"For all we know, Dad might have struck some rich ore on one of those
+claims."</p>
+
+<p>Tawney laughed. "I hardly think so. Those claims were all Jupiter
+Equilateral rejects. Our own engineers found nothing but low grade ore
+on any of them."</p>
+
+<p>"Still, it might be fun to look."</p>
+
+<p>"It could be very expensive fun. Asteroid mining is a dangerous
+business, even for experts. For amateurs...." Tawney spread his hands.
+"Accidents occur...."</p>
+
+<p>"Yes, we've heard about those accidents," Greg said coldly. "I don't
+think we're quite ready to sell, Mr. Tawney. We may never be ready to
+sell to you, so don't stop breathing until we call you. Now if there's
+nothing else, why don't you take your friends and go somewhere else?"</p>
+
+<p>The fat man scowled; he started to say something more, then saw the look
+on Greg's face, and shrugged. "I'd advise you to give it some careful
+thought," he said as he started for the door. "It might be very foolish
+for you to try to use that rig."</p>
+
+<p>Smiling, Greg closed the door in his face. Then he turned and winked at
+Tom. "Great fellow, Mr. Tawney. He almost had me sold."</p>
+
+<p>"So I noticed," Tom said. "For a while I thought you were serious."</p>
+
+<p>"Well, we found out how high they'd go. That's a very generous outfit
+Mr. Tawney works for."</p>
+
+<p>"Or else a very crooked one," Tom said. "Are you wondering the same
+thing I'm wondering?"</p>
+
+<p>"Yes," Greg said slowly. "I think I am."</p>
+
+<p>"Then that makes three of us," a heavy voice rumbled from the bedroom
+door.</p>
+
+<hr style='width: 45%;' />
+
+<p>Johnny Coombs was a tall man, so thin he was almost gangling, with a
+long nose and shaggy eyebrows jutting out over his eyes. With his rudely
+cropped hair and his huge hands, he looked like a caricature of a
+frontier Mars-farmer, but the blue eyes under the eyebrows were not
+dull.</p>
+
+<p>"Johnny!" Tom cried. "We were trying to find you."</p>
+
+<p>"I know," Johnny said. "So have a lot of other people, includin' your
+friends there."</p>
+
+<p>"Well, did you hear what Tawney wanted?"</p>
+
+<p>"I'm not so quick on my feet any more," Johnny Coombs said, "but I got
+nothin' wrong with my ears." He scratched his jaw and looked up sharply
+at Greg. "Not many people nowadays get a chance to bargain with Merrill
+Tawney."</p>
+
+<p>Greg shrugged. "He named a price and I didn't like it."</p>
+
+<p>"Three times what the rig is worth," Coombs said.</p>
+
+<p>"That's what I didn't like," Greg said. "That outfit wouldn't give us a
+break like that just for old times' sake. Do you think they would?"</p>
+
+<p>"Well, I don't know," Johnny said slowly. "Back before they built the
+city here, they used to have rats getting into the grub. Came right down
+off the ships. Got rid of most of them, finally, but it seems to me
+we've still got some around, even if they've got different shapes now."
+He jerked his thumb toward the bedroom door. "In case you're wondering,
+that's why I was standin' back there all this time ... just to make sure
+you didn't sell out to Tawney no matter what price he offered."</p>
+
+<p>Tom jumped up excitedly. "Then you know something about Dad's accident!"</p>
+
+<p>"No, I can't say I do. I wasn't there."</p>
+
+<p>"Do you really think it was an accident?"</p>
+
+<p>"Can't prove it wasn't."</p>
+
+<p>"But at least you've got some ideas," Tom said.</p>
+
+<p>"Takes more than ideas to make a case," he said at length. "But there's
+one thing I do know. I've got no proof, not a shred of it, but I'm sure
+of one thing just as sure as I'm on Mars." He looked at the twins
+thoughtfully. "Your dad wasn't just prospecting, out in the Belt. He'd
+run onto something out there, something big."</p>
+
+<p>The twins looked at him. "Run onto something?" Greg said. "You mean...."</p>
+
+<p>"I mean I think your dad hit a Big Strike out there, rich metal, a real
+bonanza lode. Maybe the biggest strike that's ever been made," the miner
+said slowly. "And then somebody got to him before he could bring it in."</p>
+
+
+

+<h2><a name="c3_Too_Many_Warnings" id="c3_Too_Many_Warnings"></a>3. Too Many Warnings</h2>
+
+
+<p>For a moment, neither of the boys could say anything at all.</p>
+
+<p>From the time they had learned to talk, they had heard stories and tales
+that the miners and prospectors told about the Big Strike, the pot of
+gold at the end of the rainbow, the wonderful, elusive goal of every man
+who had ever taken a ship into the Asteroid Belt.</p>
+
+<p>For almost a hundred and fifty years ... since the earliest days of
+space exploration ... there had been miners prospecting in the
+Asteroids. Out there, beyond the orbit of Mars and inside the orbit of
+Jupiter, were a hundred thousand ... maybe a hundred million, for all
+anybody knew ... chunks of rock, metal and debris, spinning in silent
+orbit around the sun. Some few of the Asteroids were big enough to be
+called planets ... Ceres, five hundred miles in diameter; Juno, Vesta,
+Pallas, half a dozen more. A few hundred others, ranging in size from
+ten to a hundred miles in diameter, had been charted and followed in
+their orbits by the observatories, first from Earth's airless Moon, then
+from Mars. There were tens of thousands more that had never been
+charted. Together they made up the Asteroid Belt, spread out in space
+like a broad road around the sun, echoing the age-old call of the
+bonanza.</p>
+
+<p>For there was wealth in the Asteroids ... wealth beyond a man's wildest
+dreams ... if only he could find it.</p>
+
+<p>Earth, with its depleted iron ranges, its exhausted tin and copper
+mines, and its burgeoning population, was hungry for metal. Earth needed
+steel, tin, nickel, and zinc; more than anything, Earth needed
+ruthenium, the rare-earth catalyst that made the huge solar energy
+converters possible.</p>
+
+<p>Mars was rich in the ores of these metals ... but the ores were buried
+deep in the ground. The cost of mining them, and of lifting the heavy
+ore from Mars' gravitational field and carrying it to Earth was
+prohibitive. Only the finest carbon steel, and the radioactive metals,
+smelted and purified on Mars and transported to Earth, could be made
+profitable.</p>
+
+<p>But from the Asteroid Belt, it was a different story. There was no
+gravity to fight on the tiny asteroids. On these chunks of debris, the
+metals lay close to the surface, easy to mine. Ships orbiting in the
+Belt could fill their holds with their precious metal cargoes and
+transfer them in space to the interplanetary orbit-ships spinning back
+toward Earth. It was hard work, and dangerous work; most of the ore was
+low-grade, and brought little return. But always there was the lure of
+the Big Strike, the lode of almost-pure metal that could bring a fortune
+back to the man who found it.</p>
+
+<hr style='width: 45%;' />
+
+<p>A few such strikes had been made. Forty years before a single claim had
+brought its owner seventeen million dollars in two years. A dozen other
+men had stumbled onto fortunes in the Belt ... but such metal-rich
+fragments were grains of sand in a mighty river. For every man who found
+one, a thousand others spent years looking and then perished in the
+fruitless search.</p>
+
+<p>And now Johnny Coombs was telling them that their father had been one of
+that incredible few.</p>
+
+<p>"You really think Dad hit a bonanza lode out there?"</p>
+
+<p>"That's what I said."</p>
+
+<p>"Did you see it with your own eyes?"</p>
+
+<p>"No."</p>
+
+<p>"You weren't even out there with him!"</p>
+
+<p>"No."</p>
+
+<p>"Then why are you so sure he found something?"</p>
+
+<p>"Because he told me so," Johnny Coombs said quietly.</p>
+
+<p>The boys looked at each other. "He actually <i>said</i> he'd found a rich
+lode?" Tom asked eagerly.</p>
+
+<p>"Not exactly," Johnny said. "Matter of fact, he never actually told me
+<i>what</i> he'd found. He needed somebody to sign aboard the <i>Scavenger</i>
+with him in order to get a clearance to blast off, but he never did plan
+to take me out there with him. 'I can't take you now, Johnny,' he told
+me. 'I've found something out there, but I've got to work it alone for a
+while.' I asked him what he'd found, and he just gave me that funny
+little grin of his and said, 'Never mind what it is, it's big enough for
+both of us. You just keep your mouth shut, and you'll find out soon
+enough.' And then he wouldn't say another word until we were homing in
+on the shuttle ship to drop me off."</p>
+
+<p>Johnny finished his coffee and pushed the cup aside. "I knew he wasn't
+joking. He was excited, and I think he was scared, too. Just before I
+left him, he said, 'There's one other thing, Johnny. Things might not
+work out quite the way I figure them, and if they don't ... make sure
+the twins know what I've told you.' I told him I would, and headed back.
+That was the last I heard from him until the Patrol ship found him
+floating in space with a torn-open suit and a ruined scooter floating a
+few miles away."</p>
+
+<p>"Do you think that Jupiter Equilateral knew Dad had found something?"
+Tom asked.</p>
+
+<p>"Who knows? I'm sure that <i>he</i> never told them, but it's awful hard to
+keep a secret like that, and they sound awful eager to buy that rig,"
+Johnny Coombs said.</p>
+
+<p>"Yes, and it doesn't make sense. I mean, if they were responsible for
+Dad's accident, why didn't they just check in for him on schedule and
+then quietly bring in their rig to jump the claim?"</p>
+
+<p>"Maybe they couldn't find it," Johnny said. "If they'd killed your dad,
+they wouldn't have dared hang around very long right then. Even if
+they'd kept the signal going, a Patrol ship might have come into the
+region any time. And if a U.N. Patrol ship ever caught them working a
+dead man's claim without reporting the dead man, the suit would really
+start to leak." Johnny shook his head. "Remember, your Dad had a dozen
+claims out there. They might have had to scout the whole works to find
+the right one. Much easier to do it out in the open, with your
+signatures on a claim transfer. But one thing is sure ... if they <i>knew</i>
+what Roger found out there, and where it was, Tawney would never be
+offering you triple price for the rig."</p>
+
+<p>"Then whatever Dad found is still out there," Tom said.</p>
+
+<p>"I'd bet my last dime on it."</p>
+
+<p>"There might even be something to show that the accident wasn't an
+accident," Tom went on. "Something even the Major would have to admit
+was evidence."</p>
+
+<p>Johnny Coombs pursed his lips, looking up at Tom. "Might be," he
+conceded.</p>
+
+<p>"Well, what are we waiting for? We turned Tawney's offer down ... he
+might be sending a crew out to jump the claim right now."</p>
+
+<p>"If he hasn't already," Johnny said.</p>
+
+<p>"Then we've got to get out there."</p>
+
+<p>Johnny turned to Greg. "You could pilot us out and handle the
+navigation, and as for Tom...."</p>
+
+<p>"As for Tom, he could get sick all over the place and keep us busy just
+taking care of him," Greg said sourly. "You and me, yes. Not Tom. You
+don't know that boy in a spaceship."</p>
+
+<p>Tom started to his feet, glaring at his brother. "That's got nothing to
+do with it...."</p>
+
+<p>"It's true, isn't it? You'd be a big help out there."</p>
+
+<p>Johnny looked at Tom. "You always get sick in free fall?"</p>
+
+<p>"Look, let's be reasonable," Greg said. "You'd just be in the way. There
+are plenty of things you could do right here, and Johnny and I could
+handle the rig alone...."</p>
+
+<p>Tom faced his brother angrily. "If you think I'm going to stay here and
+keep myself company, you're crazy," he said. "This is one show you're
+not going to run, so just quit trying. If you go out there, I go."</p>
+
+<p>Greg shrugged. "Okay, Twin. It's your stomach, not mine."</p>
+
+<p>"Then let me worry about it."</p>
+
+<p>"I hope," Johnny said, "that that's the worst we have to worry about.
+Let's get started planning."</p>
+
+<hr style='width: 45%;' />
+
+<p>Time was the factor uppermost in their minds. They knew that even under
+the best of conditions, it could take weeks to outfit and prepare for a
+run out to the Belt. A ship had to be leased and fueled; there were
+supplies to lay in. There was the problem of clearance to take care of,
+claims to be verified and spotted, orbit coordinates to be computed and
+checked ... a thousand details to be dealt with, anyone of which might
+delay embarkation from an hour to a day or more.</p>
+
+<p>It was not surprising that Tom and Greg were dubious when Johnny told
+them they could be ready to clear ground in less than twenty-four hours.
+Even knowing that Merrill Tawney might already have a mining crew at
+work on Roger Hunter's claims, they could not believe that the red tape
+of preparation and clearance could be cut away so swiftly.</p>
+
+<p>They underestimated Johnny Coombs.</p>
+
+<p>Six hours after he left them, he was back with a signed lease giving
+them the use of a scout-ship and fuel to take them out to the Belt and
+back again; the ship was in the Sun Lake City racks waiting for them
+whenever they were ready.</p>
+
+<p>"What kind of a ship?" Greg wanted to know.</p>
+
+<p>"A Class III Flying Dutchman with overhauled atomics and hydrazine
+side-jets," Johnny said, waving the transfer order. "Think you can fly
+it?"</p>
+
+<p>Greg whistled. "Can I? I trained in a Dutchman ... just about the
+fastest scouter there is. What condition?"</p>
+
+<p>"Lousy ... but it's fueled, with six weeks' supplies in the hold, and it
+doesn't cost us a cent. Courtesy of a friend. You'll have to check it
+over, but it'll do."</p>
+
+<p>They inspected the ship, a weatherbeaten scouter that looked like a
+relic of the '90's. Inside there were signs of many refittings and
+overhauls, but the atomics were well shielded, and it carried a
+surprising chemical fuel auxiliary for the cabin size. Greg disappeared
+into the engine room, and Tom and Johnny left him testing valves and
+circuits while they headed down to the U.N. Registry office in the
+control tower.</p>
+
+<p>On the way Johnny outlined the remaining outfitting steps. Tom would be
+responsible for getting the clearance permit through Registry; Johnny
+would check out all supplies, and then contact the observatory for the
+orbit coordinates of Roger Hunter's claims.</p>
+
+<p>"I thought the orbits were mapped on the claim papers," Tom said. "I
+mean, every time an asteroid is claimed, the orbit has to be
+charted...."</p>
+
+<p>"That's right, but the orbit goes all the way around the sun. We know
+where the <i>Scavenger</i> was when the Patrol ship found her ... but she's
+been travelling in orbit ever since. The observatory computer will
+pinpoint her for us and chart a collision course so we can cut out and
+meet her instead of trailing her for a week. Do you have the crew-papers
+Greg and I signed?"</p>
+
+<p>"Right here."</p>
+
+<p>They were stepping off the ramp below the ship when a man loomed up out
+of the shadows. It was a miner Tom had never seen before. Johnny nodded
+as he approached. "Any news, Jack?"</p>
+
+<p>"Quiet as a church," the man said.</p>
+
+<p>"We'll be held up another eight hours at least," Johnny said. "Don't go
+to sleep on us, Jack."</p>
+
+<p>"Don't worry about us sleepin'," the man said grimly. "There's been
+nobody around but yourselves, so far ... except the clearance
+inspector."</p>
+
+<p>Johnny looked up sharply. "You check his papers?"</p>
+
+<p>"<i>And</i> his prints. He was all right."</p>
+
+<p>Johnny took Tom's arm, and they headed through the gate toward the
+control tower. "I guess I'm just naturally suspicious," he grinned, "but
+I'd sure hate to have a broken cut-off switch, or a fuel valve go out of
+whack at just the wrong moment."</p>
+
+<p>"You think Tawney would dare to try something here?" Tom said.</p>
+
+<p>"Never hurts to check. We've got our hands full for a few hours getting
+set, so I just asked my friends to keep an eye on things. Always did say
+that a man who's going to gamble is smart to cover his bets."</p>
+
+<p>At the control tower they parted, and Tom walked into the clearance
+office. Johnny's watch-man had startled him, and for the first time he
+felt a chill of apprehension. If they were right ... if this trip to the
+Belt were not a wild goose chase from the very start ... then Roger
+Hunter's accident had been no accident at all.</p>
+
+<p>Quite suddenly, Tom felt very thankful that Johnny Coombs had
+friends....</p>
+
+<hr style='width: 45%;' />
+
+<p>"I don't like it," the Major said, facing Tom and Greg across the desk
+in the U.N. Registry office below the control tower. "You've gotten an
+idea in your heads, and you just won't listen to reason."</p>
+
+<p>Somewhere above them, Tom could hear the low-pitched rumble of a
+scout-ship blasting from its launching rack. "All we want to do is go
+out and work Dad's claim," he said for the second time.</p>
+
+<p>"I know perfectly well what you want to do, that's why I told the people
+here to alert me if you tried to clear a ship. You don't know what
+you're doing ... and I'm not going to sign those clearance papers."</p>
+
+<p>"Why not?" Greg said.</p>
+
+<p>"Because you're going out there asking for trouble, that's why not."</p>
+
+<p>"But you told us before that there wasn't any trouble. Dad had an
+accident, that was all. So how could we get in trouble?"</p>
+
+<p>The Major's face was an angry red. He started to say something, then
+stopped, and scowled at them instead. They met his stare. Finally he
+threw up his hands. "All right, so I can't legally stop you," he said.
+"But at least I can beg you to use your heads. You're wasting time and
+money on a foolish idea. You're walking into dangers and risks that you
+can't handle, and I hate to see it happen.</p>
+
+<p>"Mining in the Belt is a job for experienced men, not rank novices."</p>
+
+<p>"Johnny Coombs is no novice."</p>
+
+<p>"No, but he's lost his wits, taking you two out there."</p>
+
+<p>"Well, are there any other dangers you have in mind?"</p>
+
+<p>Once more the Major searched for words, and failed to find them. "No,"
+he sighed, "and you wouldn't listen if I did."</p>
+
+<p>"It seems everybody is warning us about how dangerous this trip is
+likely to be," Greg said quietly. "Last night it was Merrill Tawney. He
+offered to buy us out, he was so eager for a deal that he offered us a
+fantastic price. Then Johnny tells us that Dad mined some rich ore when
+he was out there on his last trip, but never got a chance to bring it in
+because of his ... accident. Up until now I haven't been so sure Dad
+<i>didn't</i> just have an accident, but now I'm beginning to wonder. Too
+many people have been warning us...."</p>
+
+<p>"You're determined to go out there, then?"</p>
+
+<p>"That's about right."</p>
+
+<p>The Major picked up the clearance papers, glanced at them quickly,
+and signed them. "All right, you're cleared. I hate to do it, but I
+suppose I'd go with you if the law would let me. And I'll tell you one
+thing ... if you can find a single particle of evidence that will link
+Jupiter Equilateral or anybody else to your father's death, I'll use all
+the power I have to break them." He handed the papers back to Tom. "But
+be careful, because if Jupiter Equilateral is involved in it, they're
+going to play dirty."</p>
+
+<p>At the door he turned. "Good trip, and good luck."</p>
+
+<p>Tom folded the papers and stuck them thoughtfully into his pocket.</p>
+
+<p>They met Johnny Coombs in the Registry offices upstairs; Tom patted his
+pocket happily. "We're cleared in forty-five minutes," he said.</p>
+
+<p>Johnny grinned. "Then we're all set." They headed up the ramp, reached
+ground level, and started out toward the launching racks.</p>
+
+<p>At the far end of the field a powerful Class I Ranger, one of the
+Jupiter Equilateral scout fleet, was settling down into its slot in a
+perfect landing maneuver. The triangle-and-J-insignia gleamed brightly
+on her dark hull. She was a rich, luxurious-looking ship. Many miners on
+Mars could remember when Jupiter Equilateral had been nothing more than
+a tiny mining company working claims in the remote "equilateral" cluster
+of asteroids far out in Jupiter's orbit. Gradually the company had grown
+and flourished, accumulating wealth and power as it grew, leaving behind
+it a thousand half-confirmed stories of cheating, piracy, murder and
+theft. Other small mining outfits had fallen by the wayside until now
+over two-thirds of all asteroid mining claims were held by Jupiter
+Equilateral, and the small independent miners were forced more and more
+to take what was left.</p>
+
+<p>They reached the gate to the Dutchman's launching slot and entered.</p>
+
+<p>Inside the ship Tom and Johnny strapped down while Greg made his final
+check-down on the engines, gyros and wiring. The cabin was a tiny vault,
+with none of the spacious "living room" of the orbit-ships. Tom leaned
+back in the accelleration cot, and listened to the count-down signals
+that came at one minute intervals now. In the earphones he could hear
+the sporadic chatter between Greg and the control tower. No hint that
+this was anything but a routine blastoff....</p>
+
+<p>But there was trouble ahead, Tom was certain of that. Everybody on Mars
+was aware that Roger Hunter's sons were heading out to the Belt to pick
+up where he had left off. Greg had secured a leave of absence from
+Project Star-Jump ... unhappily granted, even though his part in their
+program had already been disrupted. Even they had heard the rumors that
+were adrift....</p>
+
+<p>And if there was trouble now, they were on their own. The Asteroid Belt
+was a wilderness, untracked and unexplored, and except for an almost
+insignificant fraction, completely unknown. If there was trouble out
+there, there would be no one to help.</p>
+
+<p>Somewhere below the engines roared, and Tom felt the weight on his
+chest, sudden and breath-taking.</p>
+
+<p>They were on their way.</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="c4_Between_Mars_and_Jupiter" id="c4_Between_Mars_and_Jupiter"></a>4. "Between Mars and Jupiter...."</h2>
+
+
+<p>After all the tension of preparing for it, the trip out seemed
+interminable.</p>
+
+<p>They were all impatient to reach their destination. During blastoff and
+accelleration they had watched Mars dwindle to a tiny red dot; then time
+seemed to stop altogether, and there was nothing to do but wait.</p>
+
+<p>For the first eight hours of free fall, after the engines had cut out,
+Tom was violently ill. He fought it desperately, gulping the pills
+Johnny offered and trying to keep them down. Gradually the waves of
+nausea subsided, but it was a full twenty-four hours before Tom felt
+like stirring from his cot to take up the shipboard routine.</p>
+
+<p>And then there was nothing for him to do. Greg handled the navigation
+skilfully, while Johnny kept radio contact and busied himself in the
+storeroom, so Tom spent hours at the viewscreen. On the second day he
+spotted a tiny chunk of rock that was unquestionably an asteroid moving
+swiftly toward them. It passed at a tangent ten thousand miles ahead of
+them, and Greg started work at the computer, feeding in the data tapes
+that would ultimately guide the ship to its goal.</p>
+
+<hr style='width: 45%;' />
+
+<p>Pinpointing a given spot in the Asteroid Belt was a gargantuan task,
+virtually impossible without the aid of the ship's computer to compute
+orbits, speeds, and distances. Tom spent more and more time at the
+viewscreen, searching the blackness of space for more asteroid
+sightings. But except for an occasional tiny bit of debris hurtling by,
+he saw nothing but the changeless panorama of stars.</p>
+
+<p>Johnny Coombs found him there on the third day, and laughed at his sour
+expression. "Gettin' impatient?"</p>
+
+<p>"Just wondering when we'll reach the Belt, is all," Tom said.</p>
+
+<p>Johnny chuckled. "Hope you're not holdin' your breath. We've already
+been <i>in</i> the Belt for the last forty-eight hours."</p>
+
+<p>"Then where are all the asteroids?" Tom said.</p>
+
+<p>"Oh, they're here. You just won't see many of them. People always think
+there ought to be dozens of them around, like sheep on a hillside, but
+it just doesn't work that way." Johnny peered at the screen. "Of course,
+to an astronomer the Belt is just loaded ... hundreds of thousands of
+chunks, all sizes from five hundred miles in diameter on down. But
+actually, those chunks are all tens of thousands of miles apart, and the
+Belt <i>looks</i> just as empty as the space between Mars and Earth."</p>
+
+<p>"Well, I don't see how we're ever going to find one particular rock,"
+Tom said, watching the screen gloomily.</p>
+
+<p>"It's not too hard. Every asteroid has its own orbit around the sun, and
+everyone that's been registered as a claim has the orbit charted. The
+one we want isn't where it was when your Dad's body was found ... it's
+been travelling in its orbit ever since. But by figuring in the fourth
+dimension, we can locate it."</p>
+
+<p>Tom blinked. "Fourth dimension?"</p>
+
+<p>"Time," Johnny Coombs said. "If we just used the three linear
+dimensions ... length, width and depth ... we'd end up at the place where
+the asteroid <i>was</i>, but that wouldn't help us much because it's been
+moving in orbit ever since the Patrol Ship last pinpointed it. So we
+figure in a fourth dimension ... the time that's passed since it was last
+spotted ... and we can chart a collision course with it, figure out just
+where <i>we'll</i> have to be to meet it."</p>
+
+<p>It was the first time that the idea of time as a "dimension" had ever
+made sense to Tom. They talked some more, until Johnny started bringing
+in fifth and sixth dimensions, and problems of irrational space and
+hyperspace, and got even himself confused.</p>
+
+<p>"Anyway," Tom said, "I'm glad we've got a computer aboard."</p>
+
+<p>"And a navigator," Johnny added. "Don't sell your brother short."</p>
+
+<p>"Fat chance of that. Greg would never stand for it."</p>
+
+<p>Johnny frowned. "You lads don't like each other very much, do you?" he
+said.</p>
+
+<p>Tom was silent for a moment. Then he looked away. "We get along, I
+guess."</p>
+
+<p>"Maybe. But sometimes just gettin' along isn't enough. Especially when
+there's trouble. Give it a thought, when you've got a minute or two...."</p>
+
+<p>Later, the three of them went over the computer results together. Johnny
+and Greg fed the navigation data into the ship's drive mechanism,
+checking and rechecking speeds and inclination angles. Already the
+Dutchman's orbital speed was matching the speed of Roger Hunter's
+asteroid ... but the orbit had to be tracked so that they would arrive
+at the exact point in space to make contact. Tom was assigned to the
+viewscreen, and the long wait began.</p>
+
+<p>He spotted their destination point an hour before the computer had
+predicted contact ... at first a tiny pinpoint of reflected light in the
+scope, gradually resolving into two pinpoints, then three in a tiny
+cluster. Greg cut in the rear and lateral jets momentarily, stabilizing
+their contact course; the dots grew larger.</p>
+
+<p>Ten minutes later, Tom could see their goal clearly in the
+viewscreen ... the place where Roger Hunter had died.</p>
+
+<hr style='width: 45%;' />
+
+<p>It was neither large nor small for an asteroid, an irregular chunk of
+rock and metal, perhaps five miles in diameter, lighted only by the dull
+reddish glow from the dime-sized sun. Like many such jagged chunks of
+debris that sprinkled the Belt, this asteroid did not spin on any axis,
+but constantly presented the same face to the sun.</p>
+
+<p>Just off the bright side the orbit-ship floated, stable in its orbit
+next to the big rock, but so small in comparison that it looked like a
+tiny glittering toy balloon. And clamped on its rack on the orbit-ship's
+side, airlock to airlock, was the <i>Scavenger</i>, the little scout ship
+that Roger Hunter had brought out from Mars on his last journey.</p>
+
+<p>While Greg maneuvered the Dutchman into the empty landing rack below the
+<i>Scavenger</i> on the hull of the orbit-ship, Johnny scanned the blackness
+around them through the viewscope, a frown wrinkling his forehead.</p>
+
+<p>"Do you see anybody?" Tom asked.</p>
+
+<p>"Not a sign ... but I'm really looking for other rocks. I can see three
+that aren't too far away, but none of them have claim marks. This one
+must have been the only one Roger was working."</p>
+
+<p>They stared at the ragged surface of the planetoid. Raw veins of
+metallic ore cut through it with streaks of color, but most of the
+sun-side showed only the dull gray of iron and granite. There was
+nothing unusual about the surface that Tom could see. "Could there be
+anything on the dark side?"</p>
+
+<p>"Could be," Johnny said. "We'll have to go over it foot by foot ... but
+first, we should go through the orbit-ship and the <i>Scavenger</i>. If the
+Patrol ship missed anything, we want to know it."</p>
+
+<p>The interior of the orbit-ship was dark. It spun slowly on its axis,
+giving them just enough weight so they would not float free whenever
+they moved. Their boots clanged on the metal decks as they climbed up
+the curving corridor toward the control cabin.</p>
+
+<p>Then Johnny threw a light switch, and they stared around them in
+amazement.</p>
+
+<p>The cabin was a shambles. Everything that was not bolted down had been
+ripped open and thrown aside.</p>
+
+<p>Greg whistled through his teeth. "The Major said the Patrol crew had
+gone through the ship ... but he didn't say they'd wrecked it."</p>
+
+<p>"They didn't," Johnny said grimly. "No Patrol ship would ever do this.
+Somebody else has been here since." He turned to the control panel,
+flipped switches, checked gauges. "Hydroponics are all right. Atmosphere
+is still good; we can take off these helmets. Fuel looks all right,
+storage holds ..." He shook his head. "They weren't looting, but they
+were looking for something, all right. Let's look around and see if they
+missed anything."</p>
+
+<p>It took them an hour to survey the wreckage. Not a compartment had been
+missed. Even the mattresses on the accelleration cots had been torn
+open, the spring-stuffing tossed about helter-skelter. Tom went through
+the lock into the <i>Scavenger</i>; the scout ship too had been searched,
+rapidly but thoroughly.</p>
+
+<p>But there was no sign of anything that Roger Hunter might have found.</p>
+
+<p>Back in the control cabin Johnny was checking the ship's log. The old
+entries were on microfilm, stored on their spools near the reader. More
+recent entries were still recorded on tape. From the jumbled order,
+there was no doubt that marauders had examined them. Johnny ran through
+them nevertheless, but there was nothing of interest. Routine
+navigational data; a record of the time of contact with the asteroid; a
+log of preliminary observations on the rock; nothing more. The last tape
+recorded the call-schedule Roger Hunter had set up with the Patrol, a
+routine precaution used by all miners, to bring help if for some reason
+they should fail to check in on schedule.</p>
+
+<p>There was no hint in the log of any extraordinary discovery.</p>
+
+<p>"Are any tapes missing?" Greg wanted to know.</p>
+
+<p>"Doesn't look like it. There's one here for each day-period."</p>
+
+<p>"I wonder," Tom said. "Dad always kept a personal log. You know, a sort
+of a diary, on microfilm." He peered into the film storage bin, checked
+through the spools. Then, from down beneath the last row of spools he
+pulled out a slightly smaller spool. "Here's something our friends
+missed, I bet."</p>
+
+<p>It was not really a diary, just a sequence of notes, calculations and
+ideas that Roger Hunter had jotted down and microfilmed from time to
+time. The entries on the one spool went back for several years. Tom fed
+the spool into the reader, and they stared eagerly at the last few
+entries.</p>
+
+<p>A series of calculations, covering several pages, but with no notes to
+indicate what, exactly, Roger Hunter had been calculating. "Looks like
+he was plotting an orbit," Greg said. "But what orbit? And why? Nothing
+here to tell."</p>
+
+<p>"It must have been important, though, or Dad wouldn't have filmed the
+pages," Tom said. "Anything else?"</p>
+
+<p>Another sheet with more calculations. Then a short paragraph written in
+Roger Hunter's hurried scrawl. "No doubt now what it is," the words
+said. "Wish Johnny were here, show him a <i>real</i> bonanza, but he'll know
+soon enough if...."</p>
+
+<p>They stared at the scribbled, uncompleted sentence. Then Johnny Coombs
+let out a whoop. "I told you he found something! And he found it <i>here</i>,
+not somewhere else."</p>
+
+<p>"Hold it," Greg said, peering at the film reader. "There's something
+more on the last page, but I can't read it."</p>
+
+<p>Tom blinked at the entry. "'Inter Jovem et Martem planetam interposui,'"
+he read. He scratched his head. "That's Latin, and it's famous, too.
+Kepler wrote it, back before the asteroids were discovered. 'Between
+Jupiter and Mars I will put a planet.'"</p>
+
+<p>Greg and Johnny looked at each other. "I don't get it," Greg said.</p>
+
+<p>"Dad told me about that once," Tom said. "Kepler couldn't understand
+the long jump between Mars and Jupiter, when Venus and Earth and Mars
+were so close together. He figured there ought to be a planet out
+here ... and he was right, in a way. There wasn't any one planet, unless
+you'd call Ceres a planet, but it wasn't just empty space between Mars
+and Jupiter either. The asteroids were here."</p>
+
+<p>"But why would Dad be writing that down?" Greg asked. "And what has it
+got to do with what he found out here?" He snapped off the reader switch
+angrily. "I don't understand any of this, and I don't like it. If Dad
+found something out here, where is it? And who tore this ship apart
+after the Patrol ship left?"</p>
+
+<p>"Probably the same ones that caused the 'accident' in the first place,"
+Johnny said.</p>
+
+<p>"But why did they come back?" Greg protested. "If they killed Dad, they
+must have known what he'd found before they killed him."</p>
+
+<p>"You'd think so," Johnny conceded.</p>
+
+<p>"Then why take the risk of coming back here again?"</p>
+
+<p>"Maybe they <i>didn't</i> know," Tom said thoughtfully.</p>
+
+<p>"What do you mean?"</p>
+
+<p>"I mean maybe they killed him too soon. Maybe they thought they knew
+what he'd found and where it was ... and then found out that they
+didn't, after all. Maybe Dad hid it...."</p>
+
+<p>Johnny Coombs shook his head. "No way a man can hide an ore strike."</p>
+
+<p>"But suppose Dad did, somehow, and whoever killed him couldn't find it?
+It would be too late to make him tell them. They'd <i>have</i> to come back
+and look again, wouldn't they? And from the way they went about it, it
+looks as though they weren't having much luck."</p>
+
+<p>"Then whatever Dad found would still be here, somewhere," Greg said.</p>
+
+<p>"That's right."</p>
+
+<p>"But where? There's nothing on this ship."</p>
+
+<p>"Maybe not," Tom said, "but I'd like to take a look at that asteroid
+before we give up."</p>
+
+<hr style='width: 45%;' />
+
+<p>They paused in the big ore-loading lock to reclamp their pressure
+suit helmets, and looked down at the jagged chunk of rock a hundred
+yards below them. In the lock they had found scooters ... the little
+one-man propulsion units so commonly used for short distance work in
+space ... but decided not to use them. "They're clumsy," Johnny said,
+"and the bumper units in your suits will do just as well for this
+distance." He looked down at the rock. "I'll take the center section.
+You each take an edge and work in. Look for any signs of work on the
+surface ... chisel marks, Murexide charges, anything."</p>
+
+<p>"What about the dark side?" Greg asked.</p>
+
+<p>"If we want to see anything there, we'll either have to rig up lights or
+turn the rock around," Johnny said. "Let's cover this side first and see
+what we come up with."</p>
+
+<p>He turned and leaped from the airlock, moving gracefully down toward
+the surface, using the bumper unit to guide himself with short bursts
+of compressed CO<sub>2</sub>, from the nozzle. Greg followed, pushing off
+harder and passing Johnny halfway down. Tom hesitated. It looked easy
+enough ... but he remembered the violent nausea of his first few hours
+of free fall.</p>
+
+<p>Finally he gritted his teeth and jumped off after Greg. Instantly he
+knew that he had jumped too hard. He shot away from the orbit-ship like
+a bullet; the jagged asteroid surface leaped up at him. Frantically he
+grabbed for the bumper nozzle and pulled the trigger, trying to break
+his fall.</p>
+
+<p>He felt the nozzle jerk in his hand, and then, abruptly, he was spinning
+off at a wild tangent from the asteroid, head over heels. For a moment
+it seemed that asteroid, orbit-ship and stars were all wheeling crazily
+around him. Then he realized what had happened. He fired the bumper
+again, and went spinning twice as fast. The third time he timed the
+blast, aiming the nozzle carefully, and the spinning almost stopped.</p>
+
+<p>He fought down nausea, trying to get his bearings. He was three hundred
+yards out from the asteroid, almost twice as far from the orbit-ship. He
+stared down at the rock as he moved slowly away from it. Before, from
+the orbit-ship, he had been able to see only the bright side of the huge
+rock; now he could see the sharp line of darkness across one side.</p>
+
+<p>But there was something else....</p>
+
+<p>He fired the bumper again to steady himself, peering into the blackness
+beyond the light-line on the rock. He snapped on his helmet lamp, aimed
+the spotlight beam down to the dark rock surface. Greg and Johnny were
+landing now on the bright side, with Greg almost out of sight over the
+"horizon" ... but Tom's attention was focussed on something he could see
+only now as he moved away from the asteroid surface.</p>
+
+<p>His spotlight caught it ... something bright and metallic, completely
+hidden on the dark side, lying in close to the surface but not quite on
+the surface. Then suddenly Tom knew what it was ... the braking jets of
+a Class I Ranger, crouching beyond the reach of sunlight in the shadow
+of the asteroid....</p>
+
+<p>Swiftly he fired the bumper again, turning back toward the orbit-ship.
+His hand went to the speaker-switch, but he caught himself in time. Any
+warning shouted to Greg and Johnny would certainly be picked up by the
+ship. But he had to give warning somehow.</p>
+
+<p>He tumbled into the airlock, searching for a flare in his web belt. It
+was a risk ... the Ranger ship might pick up the flash ... but he had to
+take it. He was unscrewing the fuse cap from the flare when he saw Greg
+and Johnny leap up from the asteroid surface.</p>
+
+<p>Then he saw what had alarmed them. Slowly, the Ranger was moving out
+from its hiding place behind the rock. Tom reached out to catch Greg as
+he came plummeting into the lock. There was a flash from the Ranger's
+side, and Johnny Coombs' voice boomed in his earphones: "Get inside! Get
+the lock closed, fast ... hurry up, can't waste a second."</p>
+
+<p>Johnny caught the lip of the lock, dragged himself inside frantically.
+They were spinning the airlock door closed when they heard the
+thundering explosion, felt the ship lurch under their feet, and all
+three of them went crashing to the deck.</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="c5_The_Black_Raider" id="c5_The_Black_Raider"></a>5. The Black Raider</h2>
+
+
+<p>For a stunned moment they were helpless as they struggled to pick
+themselves up. The stable airlock deck was suddenly no longer
+stable ... it was lurching back and forth like a rowboat on a heavy sea,
+and they grabbed the shock-bars along the bulkheads to steady themselves.
+"What happened?" Greg yelped. "I saw a ship...."</p>
+
+<p>As if in answer there was another crash belowdecks, and the lurching
+became worse. "They're firing on us, that's what happened," Johnny
+Coombs growled.</p>
+
+<p>"Well, they're shaking us loose at the seams," Greg said. "We've got to
+get this crate out of here." He reached for his helmet, began unsnapping
+his pressure suit.</p>
+
+<p>"Leave it on," Johnny snapped.</p>
+
+<p>"But we can't move fast enough in these things...."</p>
+
+<p>"Leave it on all the same. If they split the hull open, you'll be dead
+in ten seconds without a suit."</p>
+
+<p>Somewhere below they heard the steady <i>clang-clang-clang</i> of the
+emergency-station's bell ... already one of the compartments somewhere
+had been breached, and was pouring its air out into the vacuum of space.
+"But what can we do?" Greg said. "They could tear us apart!"</p>
+
+<p>"First, we see what they've already done," Johnny said, spinning the
+wheel on the inner lock. "If they plan to tear us apart, we're done for,
+but they may want to try to board us.... We'll wait and see."</p>
+
+<p>An orbit-ship under fire was completely vulnerable. One well-placed
+shell could rip it open like a balloon.</p>
+
+<p>Tom and Greg followed Johnny to where the control cabin was located. In
+control they found alarm lights flashing in three places on the
+instrument panel. Another muffled crash roared through the ship, and a
+new row of lights sprang on along the panel.</p>
+
+<p>"How are the engines?" Greg said, staring at the flickering lights.</p>
+
+<p>"Can't tell. Looks like they're firing at the main jets, but they've
+ripped open three storage holds, too. They're trying to disable us...."</p>
+
+<p>"What about the <i>Scavenger</i>?"</p>
+
+<p>Johnny checked a gauge. "The airlock compartment is all right, so the
+scout ships haven't been touched. They couldn't fire on them without
+splitting the whole ship down the middle." Johnny leaned forward,
+flipped on the viewscreen, and an image came into focus.</p>
+
+<hr style='width: 45%;' />
+
+<p>It was a Class I Ranger, and there was no doubt of its origin. Like the
+one they had seen berthing at the Sun Lake City racks, this ship had a
+glossy black hull, with the golden triangle-and-J insignia standing out
+in sharp relief in the dim sunlight.</p>
+
+<p>"It's our friends, all right," Johnny said.</p>
+
+<p>"But what are they trying to do?" Tom said.</p>
+
+<p>Even as they watched, a pair of scooters broke from the side of the
+Ranger and slid down toward the sun side of the asteroid. "I don't
+know," Johnny said. "I think they intended to stay hidden, until Tom
+lost control of his bumper, and got far enough around there to spot
+them." He frowned as the first scooter touched down on the asteroid
+surface.</p>
+
+<p>"Can't we fire on them?" Greg said angrily.</p>
+
+<p>"Not the way this tub is lurching around. They've got our main gyros,
+and the auxilliaries aren't powerful enough to steady us. Another blast
+or two could send us spinning like a top, and we'd have nothing to
+stabilize us...."</p>
+
+<p>There was another flash from the Ranger's hull, and the ship jerked
+under their feet. "Well, we're a sitting duck here," Greg said. "Maybe
+those engines will still work." He slid into the control seat, flipped
+the drive switches to fire the side jets in opposite pairs. They fired,
+steadying the lurching of the ship somewhat, but there was no response
+from the main engines. "No good. We couldn't begin to run from them.
+We're stuck here."</p>
+
+<p>"They could outrun us anyway," Tom said, watching the viewscreen. "And
+they're moving in closer now."</p>
+
+<p>"They're going to board us," Tom said.</p>
+
+<p>Johnny nodded, his eyes suddenly bright. "I think you're right. And if
+they do, we may have a chance. But we've got to split up.... Greg, you
+take the control cabin here, try to keep them out if you can. Tom can
+cover the main corridor to the storage holds, and I'll take the engine
+room section. That will sew up the entrances to control, here, and give
+us a chance to stop them."</p>
+
+<p>"They may have a dozen men," Tom said. "They could just shoot us down."</p>
+
+<p>"I don't think so," Johnny said. "They want <i>us</i>, not the ship, or they
+wouldn't bother to board us. We may not be able to hold them off, but we
+can try."</p>
+
+<p>"What about making a run for it in the <i>Scavenger</i>?" Greg said.</p>
+
+<p>Johnny chuckled grimly. "It'd be a mighty short run. That Ranger's got
+homing shells that could blow the <i>Scavenger</i> to splinters if we tried
+it. Our best bet is to put up such a brawl that they think twice about
+taking us."</p>
+
+<p>They parted in the corridor outside control, Johnny heading down for the
+engine room corridors, while Tom ran up toward the main outer-shell
+corridor, a Markheim stunner in his hand. The entire outer shell of the
+ship was storage space, each compartment separately sealed and connected
+with the two main corridors that circled the ship. On each side these
+corridors came together to join the short entry corridors from the
+scout-ship airlocks.</p>
+
+<p>Tom knew that the only way the ship could be boarded was through those
+locks; a man stationed at the place where the main corridors joined
+could block any entry from the locks ... as long as he could hold his
+position. Tom reached the junction of the corridors, and crouched close
+to the wall. By peering around the corner, he had a good view of the
+airlock corridor.</p>
+
+<p>Tom gripped the Markheim tightly, and he dialed it down to a narrow
+beam. Nobody had ever been killed by a stunner ... but a direct hit with
+a narrow beam could paralyze a man for three days.</p>
+
+<p>There was movement at the far end of the airlock corridor. A helmeted
+head peered around the turn in the corridor; then two men in pressure
+suits moved into view, walking cautiously, weapons in hand. Tom shrank
+back against the wall, certain they had not seen him. He waited until
+they were almost to the junction with the main corridor; then he took
+aim and pressed the trigger stud on his Markheim. There was an ugly
+ripping sound as the gun jerked in his hand. The two men dropped as
+though they had been pole-axed.</p>
+
+<p>A shout, a scrape of metal against metal, and a shot ripped back at him
+from the end of the corridor. Tom jerked back fast, but not quite fast
+enough. He felt a sledge-hammer blow on his shoulder, felt his arm jerk
+in a cramping spasm while the corridor echoed the low rumble of
+sub-sonics. He flexed his arm to work out the spasm ... they were using
+a wide beam, hardly strong enough to stun a man. His heart pounded. They
+were being careful, very careful....</p>
+
+<p>Two more men rounded the bend in the corridor. Tom fired, but they hit
+the deck fast, and the beam missed. The first one jerked to his feet,
+charged up the corridor toward him, dodging and sliding. Tom followed
+him in his sights, fired three times as the Markheim heated up in his
+hand. The beam hit the man's leg, dumping him to the deck, and bounced
+off to catch the second one.</p>
+
+<p>But now there was another sound, coming from the corridor behind him.
+Voices, shouts, clanging of boots. He pressed against the wall,
+listening. The sounds were from below. They must have gotten past
+Johnny ... probably the men on the scooters. Tom looked around
+helplessly. If they came up behind him, he was trapped in a crossfire.
+But if he left his position, more men could come in through the airlock.
+Even now two more came around the bend, starting up the corridor for
+him....</p>
+
+<p>Quite suddenly, the lights went out.</p>
+
+<p>The men stopped. Sound stopped. The corridor was pitch black. Tom fired
+wildly down the corridor, heard shouts and oaths from the men, but he
+could see nothing. Then, ahead, a flicker of light as a headlamp went
+on. The men from the airlock were close, moving in on him, and from
+behind he saw light bouncing off the corridor walls....</p>
+
+<p>He jerked open the hatch to a storage hold, ducked inside, and slammed
+the hatch behind him. He pressed against the wall, panting.</p>
+
+<p>He waited.</p>
+
+<p>Suddenly an idea flickered in Tom's mind.</p>
+
+<p>It was a chance ... a long chance ... but it was something. If they were
+going to be captured in spite of anything they could do, even a long
+chance would be worth trying....</p>
+
+<p>He waited in the darkness, tried to think it through. It was a wild
+idea, an utterly impossible idea, he had never heard of it being tried
+before ... but <i>any</i> chance was better than none. He remembered what
+Johnny had said in the control cabin. The Ranger ship would have homing
+shells. An attempt to make a run with the <i>Scavenger</i> might be
+disastrous.</p>
+
+<p>He thought about it, trying to reason it out. The Jupiter Equilateral
+men obviously wanted them alive. They did not dare to kill Roger
+Hunter's sons, because Roger Hunter might have told them where the
+bonanza was. And Jupiter Equilateral would not dare let anyone of them
+break away. If one of them got back to Mars, the whole U.N. Patrol would
+be out in the Belt....</p>
+
+<p>The plan became clear in his mind, but he had to let Greg know. He
+fingered the control of his helmet radio. The boarding party would have
+a snooper, but if he was quick, they wouldn't have time to nail him. He
+buzzed an attention code. "Greg? Can you hear me?"</p>
+
+<p>Silence. He buzzed again, and waited. What was wrong? Had they already
+broken through to the control cabin and taken Greg? He buzzed again.
+"Greg! Sound off if you can hear me."</p>
+
+<p>More silence. Then a click. "Tom?"</p>
+
+<p>"Here. Are you all right?"</p>
+
+<p>"So far. You?"</p>
+
+<p>"They got past me, but they didn't hit me. How's Johnny?"</p>
+
+<p>"I don't know," Greg said. "I think he's been hurt. Tom, you'd better
+get off, they'll have snoopers...."</p>
+
+<p>"All right, listen," Tom said. "How does it look to you?"</p>
+
+<p>"Bad. We're outnumbered, they'll be through to here any minute."</p>
+
+<p>"All right, I've got an idea. It's risky, but it might let us pull
+something out of this mess. I'll need some time, though."</p>
+
+<p>"How much?"</p>
+
+<p>"Ten, fifteen minutes."</p>
+
+<p>There was an edge to Greg's voice. "What are you planning?"</p>
+
+<p>"I can't tell you, they're listening in. But if it works...."</p>
+
+<p>"Look, don't do anything stupid."</p>
+
+<p>"I can't hear you," Tom said. "You try to hold them for fifteen
+minutes ... and don't worry. Take care of yourself."</p>
+
+<p>Tom snapped off the speaker and moved to the hatchway. The corridor was
+empty, and pitch black. He started down toward the airlock, then stopped
+short at the sound of voices and the flicker of headlamps up ahead.</p>
+
+<p>He crouched back, but the lights were not moving. Guards at the lock,
+making certain that nobody tried to board their own ship. Tom grinned to
+himself. They weren't missing any bets, he thought.</p>
+
+<p>Except one. There was one bet they wouldn't even think of.</p>
+
+<p>He backtracked to the storage hold, crossed through it, and out into the
+far corridor. He followed the gentle curve of the deck a quarter of the
+way around the ship. Twice along the way he stumbled in the darkness,
+but saw no sign of the raiders. At last he reached the far side, and the
+corridor leading to No. 2 airlock. Again he could see the lamps of the
+guards around the bend; they were stationed directly inside their own
+lock.</p>
+
+<p>Inching forward, he peered into blackness. Each step made a muffled
+clang on the deck plates. He edged his boots along as quietly as
+possible, reaching along the wall with his hand until he felt the lip of
+a hatchway.</p>
+
+<p>The lights and voices seemed nearer now. In the dim reflected light he
+saw the sign on the door of the hatchway:</p>
+
+<div class="blockquot"><p>No. 2 Airlock</p>
+
+<p>BE SURE PRESSURE GAUGE IS AT ZERO BEFORE OPENING HATCH</p></div>
+
+<p>He checked the gauge, silently spun the wheel. There was a <i>ping</i> as the
+seals broke. He pulled the hatch open just enough to squeeze into the
+lock, then closed it behind him. Then he switched on the pumps, waiting
+impatiently until the red "all clear" signal flashed on. Then he opened
+the outside lock.</p>
+
+<p>Just beyond, he could see the sleek silvery lines of the <i>Scavenger</i>.</p>
+
+<p>It was their only chance.</p>
+
+<p>He took a deep breath, and jumped across the gap to the open lock of the
+<i>Scavenger</i>.</p>

+<h2><a name="c6_The_Last_Run_of_the_Scavenger" id="c6_The_Last_Run_of_the_Scavenger"></a>6. The Last Run of the Scavenger</h2>
+
+
+<p>To Greg Hunter the siege of the orbit-ship had been a nerve-wracking
+game of listening and waiting for something to happen.</p>
+
+<p>In the darkness of the control cabin he stretched his fingers, cramped
+from gripping the heavy Markheim stunner, and checked the corridor
+outside again. There was no sound in the darkness there, no sign of
+movement. Somewhere far below he heard metal banging on metal; minutes
+before he thought he had heard the sharp ripping sound of a stunner
+blast overhead, but he wasn't sure. Wherever the fighting was going on,
+it was not here.</p>
+
+<p>He shook his head as his uneasiness mounted. Why hadn't Johnny come
+back? He'd gone off to try and disable the Ranger ship leaving Greg to
+guard the control cabin. Why no sign of the marauders in the control
+cabin corridor? This should have been the first place they would head
+for, if they planned to take the ship, but there had been nothing but
+silence and darkness. Johnny had been gone near 15 minutes already. Greg
+became more uneasy.</p>
+
+<p>He waited. Suddenly, bitterly, he realized the hopelessness of it. Even
+if Johnny did manage to damage the Ranger ship, what difference would it
+make? They had been fools to come out here, idiots to ignore Tawney's
+warning, the three of them. Tawney had told them in so many words that
+there would be trouble, and they had come out anyway, just begging for
+it.</p>
+
+<p>Well, now they had what they'd begged for. Greg slammed his fist into
+his palm angrily. What had they expected? That the big company would
+step humbly aside for them, with a fortune hanging in the balance? If
+they had even begun to think it through before they started....</p>
+
+<p>But they hadn't, and now it was too late. They were under attack; Johnny
+was off on a fool's errand, gone too long for comfort, and Tom ... Greg
+glanced at his watch. It had been ten minutes since Tom's call. What had
+he meant by it? A plan, he said. A long chance.</p>
+
+<p>He couldn't shake off the cold feeling in his chest when he thought
+about Tom. What if something happened to him....</p>
+
+<p>Greg remembered how he had grown to resent his brother. The time when
+they were very young and Tom had been struck by the sickness, a native
+Martian virus they called it. He remembered the endless nights of
+attention given to Tom alone. From then on somehow they weren't friends
+any more. But now all that seemed to disappear and Greg only wished that
+Tom would appear down the corridor....</p>
+
+<p>A sound startled him. He tensed, gripping the stunner, peering into the
+darkness. Had he heard something? Or was it his own foot scraping on
+the deck plate? He held his breath, listening, and the sound came
+again, louder.</p>
+
+<p>Someone was moving stealthily up the corridor.</p>
+
+<p>Greg waited, covered by the edge of the hatchway. It might be Johnny
+returning, or maybe even Tom ... but there was no sign of recognition.
+Whoever it was was coming silently....</p>
+
+<p>Then a beam of light flared from a headlamp, and he saw the blue crackle
+of a stunner. He jerked back as the beam bounced off the metal walls.
+Then he was firing point blank down the corridor, his stunner on a tight
+beam, a deadly pencil of violent energy. He heard a muffled scream and a
+bulk loomed up in front of him, crashed to the deck at his feet.</p>
+
+<p>He fired again. Another crash, a shout, and then the sound of footsteps
+retreating. He waited, his heart pounding, but there was nothing more.</p>
+
+<p>The first attempt on the control cabin had failed.</p>
+
+<hr style='width: 45%;' />
+
+<p>Five minutes later the second attempt began. This time there was no
+warning sound. A sudden, ear-splitting crash, a groan of tortured metal,
+and the barricaded hatchway glowed dull red. Another crash followed. The
+edge of the hatch split open, pouring acrid Murexide fumes into the
+cabin. A third explosion breached the door six inches; Greg could see
+headlamps in the corridor beyond.</p>
+
+<p>He fired through the crack, pressing down the stud until the stunner
+scorched his hand. Then he heard boots clanging up the other corridor.
+He pressed back against the wall, waited until the sounds were near,
+then threw open the hatch. For an instant he made a perfect target, but
+the raiders did not fire. The stunner buzzed in his hand, and once again
+the footfalls retreated.</p>
+
+<p>They <i>were</i> being careful!</p>
+
+<p>Silence then, and blackness. Minutes passed ... five, ten.... Greg
+checked the time again. It was over twenty minutes since Tom had talked
+to him. What had happened? Whatever Tom had planned must have misfired,
+or something would have happened by now. For a moment he considered
+leaving his post and starting down the dark corridor to search ... but
+where to search? There was nothing to do but wait and hope for a
+miracle.</p>
+
+<p>Then suddenly the lights blazed on in the control cabin and the corridor
+outside. An attention signal buzzed in Greg's earphones. "All right,
+Hunter, it's all over," a voice grated. "You've got five minutes to get
+down to No. 3 lock. If you make us come get you, you'll get hurt."</p>
+
+<p>"I'll chance it," Greg snapped back. "Come on up."</p>
+
+<p>"We're through fooling," the voice said. "You'd better get down here.
+And bring your brother with you."</p>
+
+<p>"Sure," Greg said. "Start holding your breath."</p>
+
+<p>The contact broke for a moment, then clicked on again. This time it was
+another voice. "We've got Johnny Coombs down here," it said. "You want
+him to stay alive, you start moving. Without your stunner."</p>
+
+<p>Greg chewed his lip. They could be bluffing ... but they might not be.
+"I want to see Johnny," he said.</p>
+
+<p>On the control panel a viewscreen flickered to life. "Take a look,
+then," the voice said in his earphones.</p>
+
+<p>They had Johnny, all right. A burly guard was holding his good arm
+behind his back. Greg could see the speaker wires jerked loose from his
+helmet.</p>
+
+<p>"It's up to you," the voice said. "You've got three minutes. If you're
+not down here by then, this helmet comes off and your friend goes out
+the lock. It's quick that way, but it's not very pleasant."</p>
+
+<p>Johnny was shaking his head violently; the guard wrenched at his arm,
+and the miner's face twisted in pain. "Two minutes," the voice said.</p>
+
+<p>"Okay," Greg said. "I'm coming down."</p>
+
+<p>"Drop the stunner right there."</p>
+
+<p>He dropped the weapon onto the deck. Three steps out into the corridor,
+and two guards were there to meet him, stunners raised. They marched him
+up the ramp to the outer level corridor and around to No. 3 lock.</p>
+
+<p>They were waiting there with Johnny. A moment later the guards herded
+them through the lock and into the hold of the Ranger ship, stripped off
+their suits, and searched them.</p>
+
+<p>A big man with a heavy face and coarse black hair came into the cabin.
+He looked at Johnny and Greg and grunted. "You must be Hunter," he said
+to Greg. "Where's the other one?"</p>
+
+<p>"What other one?" Greg said.</p>
+
+<p>"Your brother. Where is he?"</p>
+
+<p>"How would I know?" Greg said.</p>
+
+<p>The man's face darkened. "You'd be smart to watch your tongue," he said.
+"We know there were three of you, we want the other one."</p>
+
+<p>The man turned to a guard. "What about it?"</p>
+
+<p>"Don't know, Doc. Nobody's reported him."</p>
+
+<p>"Then take a crew and search the ship. We were due back hours ago. He's
+in there somewhere."</p>
+
+<p>"Sure, Doc." The guard disappeared through the lock. The man called Doc
+motioned Greg and Johnny through into the main cabin.</p>
+
+<p>"What are you planning to do with us?" Greg demanded.</p>
+
+<p>"You'll find out soon enough." Doc's mouth twisted angrily.</p>
+
+<p>A guard burst into the cabin. "Doc, there's just nobody there! We've
+scoured the ship."</p>
+
+<p>"You think he just floated away in his space suit?" Doc growled. "<i>Find
+him.</i> Tawney only needs one of them, but we can't take a chance on the
+other one getting back...." He broke off, his eyes on the viewscreen.
+"Did you check those scout ships?"</p>
+
+<p>"No, I thought...."</p>
+
+<p>"Get down there and check them." Doc turned back to the viewscreen
+impatiently.</p>
+
+<p>Greg caught Johnny's eye, saw the big miner's worried frown. "Where is
+he?" he whispered.</p>
+
+<p>"I don't know. Thought you did...."</p>
+
+<p>"All I know is that he had some kind of scheme in mind."</p>
+
+<p>"Shut up," Doc said to them. "If you're smart, you'll be strapping down
+before we...." He broke off in mid sentence, listening.</p>
+
+<p>Quite suddenly, the Ranger ship had begun to vibrate. Somewhere, far
+away, there was the muffled rumble of engines.</p>
+
+<p>Doc whirled to the viewscreen. Greg and Johnny looked at the same
+instant, and Johnny groaned.</p>
+
+<p>Below them, the <i>Scavenger</i>'s jets were flaring. First the pale starter
+flame, then a long stream of fire, growing longer as the engines
+developed thrust.</p>
+
+<p>Doc slammed down a switch, roared into a speaker. "That scout
+ship ... stop it! He's trying to make a break!"</p>
+
+<p>Two guards appeared at the lock almost instantly, but it was too late.
+Already she was straining at her magnetic cable moorings; then the
+exhaust flared, and the little scout ship leaped away from the
+orbit-ship, moving out at a tangent to the asteroid's orbit, picking up
+speed, moving faster and faster....</p>
+
+<p>In toward the orbit of Mars.</p>
+
+<p>The man called Doc had gone pale. Now he snapped on the speaker again.
+"Frank? Stand by on missile control. He's asking for it."</p>
+
+<p>"Right," the voice came back. "I'm sighting in."</p>
+
+<p>The <i>Scavenger</i> was moving fast now, dwindling in the viewscreen. One
+panel of the screen went telescopic to track her. "All right," Doc said.
+"Fire one and two."</p>
+
+<p>From both sides of the Ranger, tiny rockets flared. Like twin bullets
+the homing shells moved out, side by side, in the track of the escaping
+<i>Scavenger</i>. With a strangled cry, Greg leaped forward, but Johnny
+caught his arm.</p>
+
+<p>"Johnny, <i>Tom's on ... that thing</i>...."</p>
+
+<p>"I know. But he's got a chance."</p>
+
+<p>Already the homing shells were out of sight; only the twin flares were
+visible. Greg stared helplessly at the tiny light-spot of the
+<i>Scavenger</i>. At first she had been moving straight, but now she was
+dodging and twisting, her side-jets flaring at irregular intervals. The
+twin pursuit shells mimicked each change in course, drawing closer to
+her every second.</p>
+
+<p>And then there was a flash, so brilliant it nearly blinded them, and the
+<i>Scavenger</i> burst apart in space. The second shell struck a fragment;
+there was another flash. Then there was nothing but a nebulous powdering
+of tiny metal fragments.</p>
+
+<p>The last run of the <i>Scavenger</i> had ended.</p>
+
+<p>Dazed, Greg turned away from the screen, and somewhere, as if in a
+dream, he heard Doc saying, "All right, boys, strap this pair down.
+We've got a lot of work to do before we can get out of here."</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="c7_Prisoners" id="c7_Prisoners"></a>7. Prisoners</h2>
+
+
+<p>Wherever they were planning to take them, the captors took great pains
+to make sure that their two prisoners did not escape before they were
+underway. Greg and Johnny were strapped down securely into accelleration
+cots. Two burly guards were assigned to them, and the guards were taking
+their job seriously. One of the two was watching them at all times, and
+both men held their stunners on ready.</p>
+
+<p>Meanwhile, under Doc's orders, the crew of the Jupiter Equilateral ship
+began a systematic looting of the orbit-ship they had disabled. Earlier
+they had merely searched the cabins and compartments. Now a steady
+stream of pressure-suited men crossed through the airlocks into the
+crippled vessel, marched back with packing cases full of tape records,
+microfilm spools, stored computer data ... anything that might
+conceivably contain information. The control cabin was literally torn
+apart. Every storage hold was ransacked.</p>
+
+<p>A team of six men was dispatched to the asteroid surface, searching for
+any sign of mining or prospecting activity. They came back an hour
+later, long-faced and empty handed. Doc took their reports, his scowl
+growing deeper and deeper.</p>
+
+<p>Finally the last of the searchers reported in. "Doc, we'd scraped it
+clean, and there's nothing there. Not one thing that we didn't check
+before."</p>
+
+<p>"There's <i>got</i> to be something there," Doc said.</p>
+
+<p>"You tell me where else to look, and I'll do it."</p>
+
+<p>Doc shook his head ominously. "Tawney's not going to like it," he said.
+"There's no other place it could be...."</p>
+
+<p>"Well, at least we have this pair," the other said, jerking a thumb at
+Greg and Johnny. "They'll know."</p>
+
+<p>Doc looked at them darkly. "Yes, and they'll tell, too, or I don't know
+Tawney."</p>
+
+<p>Greg watched it all happening, heard the noises, saw the packing-cases
+come through the cabin, and still he could not quite believe it. He
+caught Johnny's eye, then turned away, suddenly sick. Johnny shook his
+head. "Take it easy, boy."</p>
+
+<p>"He didn't even have a chance," Greg said.</p>
+
+<p>"I know that. He must have known it too."</p>
+
+<p>"But why? What was he thinking of?"</p>
+
+<p>"Maybe he thought he could make it. Maybe he thought it was the only
+chance...."</p>
+
+<p>There was no other answer that Greg could see, and the ache in his chest
+was deeper.</p>
+
+<p>There was no way to bring Tom back now. However things had been between
+them, they could never be changed now. But he knew that as long as he
+was still breathing, somebody somehow was going to answer for that last
+desperate run of the <i>Scavenger</i>....</p>
+
+<hr style='width: 45%;' />
+
+<p>It had been an excellent idea, Tom Hunter thought to himself, and it had
+worked perfectly, exactly as he had planned it ... so far. But now, as
+he clung to his precarious perch, he wondered if it had not worked out a
+little too well. The first flush of excitement that he had felt when he
+saw the <i>Scavenger</i> blow apart in space had begun to die down now; on
+its heels came the unpleasant truth, the realization that only the easy
+part lay behind him so far. The hard part was yet to come, and if that
+were to fail....</p>
+
+<p>He realized, suddenly, that he was afraid. He was well enough concealed
+at the moment, clinging tightly against the outside hull of the Ranger
+ship, hidden behind the open airlock door. But soon the airlock would be
+pulled closed, and then the real test would come.</p>
+
+<p>Carefully, he ran through the plan again in his mind. He was certain now
+that his reasoning was right. There had been two dozen men on the raider
+ship; there had been no question, even from the start, that they would
+succeed in boarding the orbit-ship and taking its occupants prisoners.
+The Jupiter Equilateral ship had not appeared there by coincidence. They
+had come looking for something that they had not found.</p>
+
+<p>And the only source of information left was Roger Hunter's sons. The
+three of them together might have held the ship for hours, or even
+days ... but with engines and radios smashed, there had been no hope
+of contacting Mars for help. Ultimately, they would have been taken.</p>
+
+<p>As he had crouched in the dark storage hold in the orbit-ship, Tom had
+realized this. He had also realized that, once captured, they would
+never have been freed and allowed to return to Mars.</p>
+
+<p>If the three of them were taken, they were finished. But what if only
+two were taken? He had pushed it aside as a foolish idea, at first. The
+boarding party would never rest until they had accounted for all three.
+They wouldn't dare go back to their headquarters leaving one live man
+behind to tell the story....</p>
+
+<p>Unless they thought the third man was dead. If they were sure of
+that ... <i>certain</i> of it ... they would not hesitate to take the
+remaining two away. And if, by chance, the third man wasn't as dead as
+they thought he was, and could find a way to follow them home, there
+might still be a chance to free the other two.</p>
+
+<p>It was then that he thought of the <i>Scavenger</i>, and knew that he had
+found a way.</p>
+
+<p>In the cabin of the little scout ship he had worked swiftly, fearful
+that at any minute one of the marauders might come aboard to search it.
+Tom was no rocket pilot, but he did know that the count-down was
+automatic, and that every ship could run on an autopilot, as a drone,
+following a prescribed course until it ran out of fuel. Even the
+shell-evasion mechanism could be set on automatic....</p>
+
+<p>Quickly he set the autopilot, plotted a simple high school math course
+for the ship, a course the Ranger ship would be certain to see, and to
+fire upon. He set the count-down clock to give himself plenty of time
+for the next step.</p>
+
+<p>Both the airlock to the <i>Scavenger</i> and to the orbit-ship worked on
+electric motors. The <i>Scavenger</i> was grappled to the orbit-ship's hull
+by magnetic cables. Tom dug into the ship's repair locker, found the
+wires and fuses that he needed, and swiftly started to work.</p>
+
+<p>It was an ingenious device. The inner airlock door in the orbit-ship was
+triggered to a fuse. He had left it ajar; the moment it was closed, by
+anyone intending to board the <i>Scavenger</i>, the fuse would burn, a
+circuit would open, and the little ship's autopilot would go on active.
+The ship would blast away from its moorings, head out toward Mars....</p>
+
+<p>And the fireworks would begin. All that he would have to worry about
+then would be getting himself aboard the Ranger ship without being
+detected.</p>
+
+<p>Which was almost impossible. But he knew there was a way. There was one
+place no one would think to look for him, if he could manage to keep out
+of range of the viewscreen lenses ... the outer hull of the ship. If he
+could clamp himself to the hull, somehow, and manage to cling there
+during blastoff, he could follow Greg and Johnny right home.</p>
+
+<p>He checked the fuse on the airlock once again to make certain it would
+work. Then he waited, hidden behind the little scout ship's hull,
+until the orbit-ship swung around into shadow. He checked his suit
+dials ... oxygen for twenty-two hours, heater pack fully charged,
+soda-ash only half saturated ... it would do. Above him he could see the
+rear jets of the Ranger. He swung out onto the orbit-ship's hull, and
+began crawling up toward the enemy ship.</p>
+
+<p>It was slow going. Every pressure suit had magnetic boots and hand-pads
+to enable crewmen to go outside and make repairs on the hull of a ship
+in transit. Tom clung, and moved, and clung again, trying to reach the
+protecting hull of the Ranger before the orbit-ship swung him around to
+the sun-side again....</p>
+
+<p>He couldn't move fast enough. He saw the line of sunlight coming around
+the ship as it swung full into the sun. He froze, crouching motionless.
+If somebody on the Ranger spotted him now, it was all over. He was
+exposed like a lizard on a rock. He waited, hardly daring to breathe, as
+the ship spun ponderously around, carrying him into shadow again.</p>
+
+<p>And nothing happened. He started crawling upward again, reached up to
+grab the mooring cable, and swung himself across to the hull of the
+Ranger. The airlock hung open; he scuttled behind it, clinging to the
+hull in its shadow just as Greg and Johnny were herded across by the
+Jupiter Equilateral guards.</p>
+
+<p>Then he waited. There was no sound, no sign of life. After a while the
+Ranger's inner lock opened, and a group of men hurried across to the
+orbit-ship. Probably a searching party, Tom thought. Soon the men came
+back, then returned to the orbit-ship. After another minute, he felt the
+vibration of the <i>Scavenger</i>'s motors, and he knew that his snare had
+been triggered.</p>
+
+<p>He saw the little ship break free and streak out in its curving
+trajectory. He saw the homing shells burst from the Ranger's tubes. The
+<i>Scavenger</i> vanished from his range of vision, but moments later he saw
+the sudden flare of light reflected against the hull of the orbit-ship,
+and he knew his plan had worked, but the ordeal lay ahead.</p>
+
+<p>And at the end of it, he might really be a dead man.</p>
+
+<hr style='width: 45%;' />
+
+<p>Hours later, the last group of looters left the orbit-ship, and the
+airlock to the Ranger clanged shut. Tom heard the sucking sound of the
+air-tight seals, then silence. The orbit-ship was empty, its insides
+gutted, its engines no longer operable. The Ranger hung like a long
+splinter of silver alongside her hull, poised and ready to move on.</p>
+
+<p>He knew that the time had come. Very soon the blastoff and the
+accelleration would begin. He had a few moments to find a position of
+safety, no more.</p>
+
+<p>Quickly, he began scrambling toward the rear of the Ranger's hull,
+hugging the metal sides, moving sideways like a crab. Ahead, he knew,
+the viewscreen lenses would be active; if one of them picked him up, it
+would be quite a jolt to the men inside the ship ... but it would be the
+end of his free ride.</p>
+
+<p>But the major peril was the blastoff. Once the engines cut off, the ship
+would be in free fall. Then he could cling easily to the hull, walk all
+over it if he chose to, with the aid of his boots and hand-pads. But
+unless he found a way to anchor himself firmly to the hull during
+blastoff, he could be flung off like a pebble.</p>
+
+<p>He heard a whirring sound, and saw the magnetic mooring cables jerk. The
+ship was preparing for blastoff. Automatic motors were drawing the
+cables and grappling plates into the hull. Moving quickly, Tom reached
+the rear cable. Here was his anchor, something to hold him tight to the
+hull! With one hand he loosened the web belt of his suit, looped it over
+a corner of the grappling plate as it pulled in to the hull.</p>
+
+<p>The plate pulled tight against the belt. Each plate fit into a shallow
+excavation in the hull, fitting so tightly that the plates were all but
+invisible when they were in place. Tom felt himself pulled in tightly as
+the plate gripped the belt against the metal, and the whirring of the
+motor stopped.</p>
+
+<p>For an instant it looked like the answer. The belt was wedged
+tight ... he couldn't possibly pull loose without ripping the nylon
+webbing of the belt. But a moment later the motor started whirring again.
+The plate pushed out from the hull a few inches, then started back, again
+pulling in the belt....</p>
+
+<p>A good idea that just wouldn't work. The automatic machinery on a
+spaceship was built to perfection; nothing could be permitted to
+half-work. Tom realized what was happening. Unless the plate fit
+perfectly in its place, the cable motor could not shut off, and
+presently an alarm signal would start flashing on the control panel.</p>
+
+<p>He pulled the belt loose, reluctantly. He would have to count on his
+boots and his hand-pads alone.</p>
+
+<p>He searched the rear hull, looking for some break in the polished metal
+that might serve as a toehold. To the rear the fins flared out,
+supported by heavy struts. He made his way back, crouching close to the
+hull, and straddled one of the struts. He jammed his magnetic boots down
+against the hull, and wrapped his arms around the strut with all his
+strength.</p>
+
+<p>Clinging there, he waited.</p>
+
+<p>It wasn't a good position. The metal of the strut was polished and
+slick, but it was better than trying to cling to the open hull. He
+tensed now, not daring to relax for fear that the blastoff accelleration
+would slam him when he was unprepared.</p>
+
+<p>Deep in the ship, the engines began to rumble. He felt it rather
+than heard it, a low-pitched vibration that grew stronger and stronger.
+The Ranger would not need a great thrust to move away from the
+orbit-ship ... but if they were in a hurry, they might start out at
+nearly Mars-escape....</p>
+
+<p>The jets flared, and something slammed him down against the fin strut.
+The Ranger moved out, its engines roaring, accellerating hard. Tom felt
+as though he had been hit by a ton of rock. The strut seemed to press in
+against his chest; he could not breathe. His hands were sliding, and he
+felt the pull on his boots. He tightened his grip desperately. This was
+it. He had to hang on, <i>had</i> to hang on....</p>
+
+<p>He saw his boot on the hull surface, sliding slowly, creeping back and
+stretching his leg, suddenly it broke loose; he lurched to one side, and
+the other boot began sliding. There was a terrible ache in his arms, as
+though some malignant giant were tearing at him, trying to wrench him
+loose as he fought for his hold.</p>
+
+<p>There was one black instant when he knew he could not hold on another
+second. He could see the blue flame of the jet streaming behind him, the
+cold blackness of space beyond that. It had been a fool's idea, he
+thought in despair, a million-to-one shot that he had taken, and
+lost....</p>
+
+<p>And then the pressure stopped. His boots clanged down on the hull, and
+he almost lost his hand-grip. He stretched an arm, shook himself, took a
+great painful breath, and then clung to the strut, almost sobbing,
+hardly daring to move.</p>
+
+<p>The ordeal was over. Somewhere, far ahead, an orbit-ship was waiting for
+the Ranger to return. He would have to be ready for the braking thrust
+and the side-maneuvering thrusts, but he would manage to hold on.
+Crouching against the fin, he would be invisible to viewers on the
+orbit-ship ... and who would be looking for a man clinging to the
+outside of a scout-ship?</p>
+
+<p>Tom sighed, and waited. Jupiter Equilateral would have its prisoners,
+all right. He wished now that he had not discarded the stunner, but
+those extra pounds might have made the difference between life and death
+during the blastoff. And at least he was not completely unarmed. He
+still had Dad's revolver at his side.</p>
+
+<p>He smiled to himself. The pirates would have their prisoners,
+indeed ... but they would have one factor to deal with that they
+had not counted on.</p>
+
+<hr style='width: 45%;' />
+
+<p>For Greg it was a bitter, lonely trip.</p>
+
+<p>After ten hours they saw the huge Jupiter Equilateral orbit-ship looming
+up in the viewscreen like a minor planet. Skilfully Doc maneuvered the
+ship into the launching rack. The guards unstrapped the prisoners, and
+handed them pressure suits.</p>
+
+<p>Moments later they were in a section in crews' quarters where they
+stripped off their suits. This orbit-ship was much larger than Roger
+Hunter's; the gravity was almost Mars-normal, and it was comforting just
+to stretch and relax their cramped muscles.</p>
+
+<p>As long as they didn't think of what was ahead.</p>
+
+<p>Finally Johnny grinned and slapped Greg's shoulder. "Cheer up," he said.
+"We'll be honored guests for a while, you can bet on that."</p>
+
+<p>"For a while," Greg said bitterly.</p>
+
+<p>Just then the hatchway opened. "Well, who do we have here?" a familiar
+voice said. "Returning a call, you might say. And maybe this time you'll
+be ready for a bit of bargaining."</p>
+
+<p>They turned to see the heavy face and angry eyes of Merrill Tawney.</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="c8_The_Scavengers_of_Space" id="c8_The_Scavengers_of_Space"></a>8. The Scavengers of Space</h2>
+
+
+<p>The casual observer might have been fooled. Tawney's guard was down only
+for an instant; then the expression of cold fury and determination on
+his face dropped away as though the shutter of a camera had clicked, and
+he was all smiles and affability. They were honored guests here, one
+would have thought, and this pudgy agent of the Jupiter Equilateral
+combine was their genial host, anxious for their welfare, eager to do
+anything he could for their comfort....</p>
+
+<p>They were amazed by the luxuriousness of the ship. For the next few
+hours they received the best treatment, sumptuous accommodations,
+excellent food.</p>
+
+<p>They were finishing their second cup of coffee when Tawney asked,
+"Feeling better, gentlemen?"</p>
+
+<p>"You do things in a big way," Johnny said. "This is real coffee, made
+from grounds. Must have cost a fortune to ship it out here."</p>
+
+<p>Tawney spread his hands. "We keep it for special occasions. Like when we
+have special visitors."</p>
+
+<p>"Even when the visits aren't voluntary," Greg added sourly.</p>
+
+<p>"We have to be realistic," Tawney said. "Would you have come if we
+invited you? Of course not. You gentlemen chose to come out to the Belt
+in spite of my warnings. You thus made things very awkward for us, upset
+certain of our plans." He looked at Greg. "We don't ordinarily allow
+people to upset our plans, but now we find that we're forced to include
+you in our plans, whether you happen to like the idea or not."</p>
+
+<p>"You're doing a lot of talking," Greg said. "Why don't you come to the
+point?"</p>
+
+<p>Tawney was no longer smiling. "We happen to know that your father struck
+a rich lode on one of his claims."</p>
+
+<p>"That's interesting," Greg said. "Did Dad tell you that?"</p>
+
+<p>"He didn't have to. A man can't keep a secret like that, not for very
+long. Ask your friend here, if you don't believe me. And we make it our
+business to know what's going on out here. We have to, in order to
+survive."</p>
+
+<p>"Well, suppose you heard right. The law says that what a man finds on
+his own claim is his."</p>
+
+<p>"Certainly," Tawney said. "Nobody would think of claim-jumping, these
+days. But when a man happens to die before he can bring in his bonanza,
+then it's a question of who gets there first, wouldn't you think?"</p>
+
+<p>"Not when the man is murdered," Greg said hotly, "not by a long shot."</p>
+
+<p>"But you can't prove that your father was murdered."</p>
+
+<p>"If I could, I wouldn't be here."</p>
+
+<p>"Then I think we'll stick to the law," Tawney said, "and call it an
+accident."</p>
+
+<p>"And what about my brother? Was that an accident?"</p>
+
+<p>"Ah, yes, your brother." Tawney's eyes hardened. "Quite a different
+matter, that. Sometimes Doc tends to be over-zealous in carrying out his
+assigned duties. I can assure you that he has been ... disciplined."</p>
+
+<p>"That's not going to help Tom very much."</p>
+
+<p>"Unfortunately not," Tawney said. "Your brother made a very foolish
+move, under the circumstances. But from a practical point of view,
+perhaps it's not entirely a tragedy."</p>
+
+<p>"What do you mean by that?"</p>
+
+<p>"From what I've heard," Tawney said, "you didn't have much use for your
+twin brother. And now you certainly won't have to share your father's
+legacy...."</p>
+
+<p>It was too much. With a roar Greg swung at the little fat man. The blow
+caught Tawney full in the jaw, jerked his head back. Greg threw his
+shoulder into a hard left, slamming Tawney back against the wall. The
+guard charged across the room, dragging them apart as Tawney blubbered
+and tried to cover his face. Greg dug his elbow into the guard's
+stomach, twisted away and started for Tawney again. Then Johnny caught
+his arm and spun him around. "Stop it," he snapped. "Use your head,
+boy...."</p>
+
+<p>Greg stopped, glaring at Tawney and gasping for breath. The company man
+picked himself up, rubbing his hand across his mouth. For a moment he
+trembled with rage. Then he gripped the table with one hand, forcibly
+regaining his control. He even managed a sickly smile. "Just like your
+father," he said, "too hot-headed for your own good. But we'll let it
+pass. I brought you here to make you an offer, a very generous offer,
+and I'll still make it. I'm a businessman, when I want something I want
+I bargain for it. If I have to share a profit to get it, I share the
+profit. All right ... you know where your father's strike is. We want
+it. We can't find it, so you've got us over a barrel. We're ready to
+bargain."</p>
+
+<p>Greg started forward. "I wouldn't bargain with you for...."</p>
+
+<p>"Shut up, Greg," Johnny said.</p>
+
+<p>Greg stared at him. The big miner's voice had cracked like a whip; now
+he was drawing Merrill Tawney aside, speaking rapidly into his ear.
+Tawney listened, shot a venomous glance across at Greg, and finally
+nodded. "All right," he said, "but I can't wait forever...."</p>
+
+<p>"You won't have to."</p>
+
+<p>Tawney turned to the guard. "You have your orders," he said. "They're to
+have these quarters, and the freedom of the ship, except for the outer
+level. They're not to be harmed, and they're not to be out of your sight
+except when they're locked in here. Is that clear?"</p>
+
+<p>The guard nodded. Tawney looked at Johnny, and started for the door,
+still rubbing his jaw. "We'll talk again later," he said, and then he
+was gone.</p>
+
+<p>When the guard had left, and the lock buzzed in the door, Johnny looked
+at Greg and shook his head sadly. "You just about fixed things, boy, you
+really did. You've got to use your head if you want to stay alive a
+while, that's all. Look, there isn't going to be any bargaining with
+Tawney, he just doesn't work that way. It's heads he wins, tails we
+lose. Once he has what he wants we won't last six minutes. All right,
+then there's just one thing that can keep us alive ... stalling him.
+We've got to make him think you'll give in if he plays his cards right."</p>
+
+<p>Greg was silent for a minute. "I hadn't thought of it that way."</p>
+
+<p>"And we've got to use the time we have to find some way to break for
+it." Johnny stood up, staring around the luxurious lounge. "If you want
+my opinion, it's going to take some pretty fancy footwork to get out of
+here with our skins."</p>
+
+<hr style='width: 45%;' />
+
+<p>True to his word, Tawney had given them the freedom of the ship. Greg
+and Johnny discovered that their guard was also an excellent guide. All
+day he had been leading them through the ship, chatting and answering
+their questions about asteroid mining, until they almost forgot that
+they were really prisoners here. And the guard's obvious pride in the
+scope and skill of his company's mining operations was strangely
+infectious.</p>
+
+<p>Watching the Jupiter Equilateral ship in operation, Greg felt his heart
+sink. Here was a huge, powerful organization, with all the equipment and
+men and know-how they could ever need. How could one man, or two or
+three in a team, hope to compete with them? For the independent miner,
+the only hope was the Big Strike, the single lode that could make him
+rich. He might work all his life without finding it, and then stumble
+upon it by sheer chance....</p>
+
+<p>But if he couldn't keep it when he found it, then what? What if the
+great mining company became so strong that they could be their own law
+in the Belt? What if they grew strong enough and powerful enough to
+challenge the United Nations on Mars itself, and gain control of the
+entire mining industry? What chance would the independent miner have
+then?</p>
+
+<p>It was a frightening picture. Suddenly something began to make sense to
+Greg; he realized something about his father that he had never known
+before.</p>
+
+<p>Roger Hunter had been a miner, yes. But he had been something else too,
+something far more important than just a miner.</p>
+
+<p>Roger Hunter had been a fighter, fighting to the end for something he
+believed in....</p>
+
+<p>Tawney interrupted Greg's thought.</p>
+
+<p>"Quite an operation," he said.</p>
+
+<p>Greg looked at him. "So I see."</p>
+
+<p>"And very efficient, too. Our men have everything they need to work
+with. We can mine at far less cost than anyone else."</p>
+
+<p>"But you still can't stand the idea of independent miners working the
+Belt," Greg said.</p>
+
+<p>Tawney's eyebrows went up. "But why not? There's lots of room out here.
+Our operation with Jupiter Equilateral is no different from an
+independent miner's operation. We aren't different kinds of people."
+Tawney smiled. "When you get right down to it, we're both exactly the
+same thing ... scavengers in space, vultures picking over the dead
+remains to see what we can find. We come out to the asteroids, and we
+bring back what we want and leave the rest behind. And it doesn't matter
+whether we've got one ship working or four hundred ... we're still just
+scavengers."</p>
+
+<p>"With just one difference," Greg said, turning away from the viewscreen.</p>
+
+<p>"Difference?"</p>
+
+<p>Greg nodded. "Even vultures don't kill their own," he said.</p>
+
+<hr style='width: 45%;' />
+
+<p>Later, when they were alone in their quarters again, Greg and Johnny
+stared at each other gloomily.</p>
+
+<p>"Didn't you see <i>anything</i> that might help us?" Greg said.</p>
+
+<p>"Not much. For an orbit-ship, this place is a fortress. I got a good
+look at that scout ship coming in ... it was armed to the teeth.
+Probably they all are. And they're keeping a guard now at every
+airlock."</p>
+
+<p>"So we're sewed up tight," Greg said.</p>
+
+<p>"Looks that way. They've got us, boy, and I think Tawney's patience is
+wearing thin, too. We're either going to have to produce or else."</p>
+
+<p>"But what can we do?"</p>
+
+<p>"Start bluffing."</p>
+
+<p>"It seems to me we're just about bluffed out."</p>
+
+<p>"I mean talk business," Johnny said. "Tell Tawney what he wants to
+know."</p>
+
+<p>"When we don't know any more than he does? How?"</p>
+
+<p>Johnny Coombs scratched his jaw. "I've been thinking about that," he
+said slowly, "and I wonder if we don't know a whole lot more than we
+think we do."</p>
+
+<p>"Like what?" Greg said.</p>
+
+<p>"We've all been looking for the same thing ... a Big Strike, a bonanza
+lode. Tawney's men have raked over every one of your Dad's claims, and
+they haven't turned up a thing." Johnny looked at Greg. "Makes you
+wonder a little, doesn't it? Your Dad was smart, but he was no magician.
+And how does a man go about hiding something like a vein of ore?"</p>
+
+<p>"I don't know," Greg said. "It doesn't seem possible."</p>
+
+<p>"It isn't possible," Johnny said flatly. "There's only one possible
+explanation, and we've been missing it all along. Whatever he found, <i>it
+wasn't an ore strike</i>. It was something else, something far different
+from anything we've been thinking of."</p>
+
+<p>Greg stared at him. "But if it wasn't an ore strike, what was it?"</p>
+
+<p>"I don't know," Johnny said. "But I'm sure of one thing ... it was
+something important enough that he was ready to die before he'd reveal
+it. And that means it was important enough that Tawney won't dare kill
+us until he finds out what it was."</p>

+<h2><a name="c9_The_Invisible_Man" id="c9_The_Invisible_Man"></a>9. The Invisible Man</h2>
+
+
+<p>Crouching back into the shadow, Tom Hunter waited as the heavy footsteps
+moved up the corridor, then back down, then up and down again. He peered
+around the corner for a moment, looking quickly up and down the curving
+corridor. The guard was twenty yards away, moving toward him in a slow
+measured pace. Tom jerked his head back, then peered out again as the
+footsteps receded.</p>
+
+<p>The guard was a big man, with a heavy-duty stunner resting in the crook
+of his elbow. He paused, scratched himself, and resumed his pacing. Tom
+waited, hoping that something might distract the big man, but he moved
+stolidly back and forth, not too alert, but far too alert to risk
+breaking out into the main corridor.</p>
+
+<p>Tom moved back into the darkened corridor where he was standing, trying
+to decide what to do. It was a side corridor, and a blind alley; it
+ended in a large hatchway marked HYDROPONICS, and there were no
+branching corridors. If he were discovered here, there would be no place
+to hide.</p>
+
+<p>But he knew that he could never hope to accomplish his purpose here....</p>
+
+<p>A hatch clanged open, and there were more footsteps down the main
+corridor as a change of guards hurried by. There was a rumble of voices,
+and Tom listened to catch the words.</p>
+
+<p>"... don't care what you think, the boss says tighten it up...."</p>
+
+<p>"But they got them locked in...."</p>
+
+<p>"So tell it to the boss. We're supposed to check every compartment in
+the section every hour. Now get moving...."</p>
+
+<p>The footsteps moved up and down the corridor then, and Tom heard hatches
+clanging open. If they sent a light down this spur ... he turned to the
+hatch, spun the big wheel on the door, and slipped inside just as the
+footsteps came closer.</p>
+
+<p>The stench inside was almost overpowering. The big, darkened room was
+extremely warm, the air damp with vapor. The plastic-coated walls
+streamed with moisture. Against the walls Tom could see the great
+hydroponic vats that held the yeast and algae cultures that fed the crew
+of the ship. Water was splashing in one of the vats, and there was a
+gurgling sound as nutrient broth drained out, to be replaced with
+fresh.</p>
+
+<p>He moved swiftly across the compartment, into a darkened area behind the
+rows of vats, and crouched down. He heard footsteps, and the ring of
+metal as the hatchway came open. One of the guards walked in, peered
+into the gloom, wrinkled his nose, and walked out again, closing the
+hatchway behind him.</p>
+
+<p>It would do for a while ... if he didn't suffocate ... but if this ship
+was organized like smaller ones, it would be a blind alley. Modern
+hydroponic tanks did not require much servicing, once the cultures were
+growing; the broth was drained automatically and sluiced through a
+series of pipes to the rendering plant where the yeasts could be
+flavored and pressed into surrogate steaks and other items for spaceship
+cuisine. There would be no other entrances, no way to leave except the
+way he had come in.</p>
+
+<p>And with the guards on duty, that was out of the question. He waited,
+listening, as the check-down continued in nearby compartments. Then
+silence fell again. The heavy yeast aroma had grown more and more
+oppressive; now suddenly a fan went on with a whir, and a cool draft of
+freshened reprocessed air poured down from the ventilator shaft above
+his head.</p>
+
+<p>Getting into the orbit-ship had been easier than he had hoped. In the
+excitement as the new prisoners were brought aboard, security measures
+had been lax. No one had expected a third visitor; in consequence, no
+one looked for one. Huge as it was, the Jupiter Equilateral ship had
+never been planned as a prison, and it had taken time to stake out the
+guards in a security system that was at all effective. In addition,
+every man who served as a guard had been taken from duty somewhere else
+on the ship.</p>
+
+<p>So there had been no guard at the airlock in the first few moments after
+the prisoners were taken off the Ranger ship. Tom had waited until the
+ship was moored, clinging to the fin strut. He watched Greg and Johnny
+taken through the lock, and soon the last of the crew had crossed over
+after securing the ship. Presently the orbit-ship airlock had gone dark,
+and only then had he ventured from his place of concealment, creeping
+along the dark hull of the Ranger ship and leaping across to the
+airlock.</p>
+
+<p>A momentary risk, then, as he opened the lock. In the control room, he
+knew, a signal light would blink on a panel as the lock was opened. Tom
+moved as quickly as he could, hoping that in the excitement of the new
+visitors, the signal would go unnoticed ... or if spotted, that the
+spotter would assume it was only a crewman making a final trip across to
+the Ranger ship.</p>
+
+<p>But once inside, he began to realize the magnitude of his problem. This
+was not a tiny independent orbit-ship with a few corridors and
+compartments. This was a huge ship, a vast complex of corridors and
+compartments and holds. There was probably a crew of a thousand men on
+this ship ... and there was no sign where Greg and Johnny might have
+been taken.</p>
+
+<p>He moved forward, trying to keep to side corridors and darkened areas.
+In the airlock he had wrapped up his pressure suit and stored it on a
+rack; no one would notice it there, and it might be handy later. He had
+strapped his father's gun case to his side, some comfort, but a small
+one.</p>
+
+<p>Now, crouching behind the yeast vat, he lifted out the gun, hefted it
+idly in his hand. It was a weapon, at least. He was not well acquainted
+with guns, and in the shadowy light it seemed to him that this one
+looked odd for a revolver; it even felt wrong, out of balance in his
+hand. He slipped it back in the case. After all, it had been fitted to
+Dad's hand, not his. And Johnny or Greg would know how to use it better
+than he would.</p>
+
+<p>If he could find them. But to do that, he would have to search the ship.
+He would have to move about, he couldn't just wait in a storage hold.
+And with all the guards that were posted, he would certainly stumble
+into one of them sooner or later if he tried leaving this spot....</p>
+
+<p>He shook his head, and started for the hatch. He would have to chance
+it. There was no way to tell how much time he had, but it was a sure bet
+that he didn't have very long.</p>
+
+<p>In the spur corridor again, he waited until the guard's footsteps were
+muffled and distant. Then he darted out into the main corridor, moving
+swiftly and silently away from the guard. At the first hatchway he
+ducked inside, waited in the darkness, panting....</p>
+
+<p>The guard had stopped walking. Then his footsteps resumed, but more
+quickly, coming down the corridor. He stopped, almost outside the
+hatchway door. "Funny," Tom heard him mutter. "I'd have sworn...."</p>
+
+<p>Tom held his breath, waiting. This was a storage hold, but he didn't
+dare to move, even to take cover. The guard stood motionless for a
+moment, then grunted, and resumed his slow pacing.</p>
+
+<p>When he had moved away Tom caught his breath in huge gasps, his heart
+beating in his throat. It was no use, he thought in despair. Once or
+twice he might get away with it, but sooner or later a guard would be
+alert enough to investigate an obscure noise, a flicker of movement in
+the corner of his eye....</p>
+
+<p>There had to be another way. His eye probed the storage hold,
+hopelessly, and then stopped on a metal grill in the wall.</p>
+
+<p>For a moment, he didn't recognize what it was. Then there was a
+<i>whoosh-whoosh-whoosh</i> as a fan went on, and he felt cool air against
+his cheek. He held out his hand to the grill, found the air coming from
+there.</p>
+
+<p>A ventilation shaft. Every space craft had to have reconditioning units
+for the air inside the ship; the men inside needed a constant supply of
+fresh oxygen, but even more, without pumps to move the air in each
+compartment they would soon suffocate from the accumulation of carbon
+dioxide in the air they breathed out, or bake from the heat their bodies
+radiated. On the other hand, the yeasts and algae required carbon
+dioxide and yielded copious amounts of oxygen as they grew.</p>
+
+<p>In Roger Hunter's little orbit-ship the ventilation shafts were small, a
+loose network of foot-square ducts leading from the central pumps and
+air-reconditioning units to every compartment in the ship. But in a ship
+of this size....</p>
+
+<p>The grill was over a yard wide, four feet tall. It started about
+shoulder height and ran up to the overhead. The ducts would network the
+ship, opening into every compartment, and no one would ever open them
+unless something went wrong.</p>
+
+<p>And then he was laughing out loud, working the grill out of the slots
+that held it to the wall, trying to make his hands work in his
+excitement.</p>
+
+<p>He knew he had found his answer.</p>
+
+<p>The grill came loose, lifted down in a piece. He stopped short as
+footsteps approached in the corridor, paused, and went on. Then he
+peered into the black gaping hole behind the grill. It was big enough
+for a man to crawl in. He shinned up into the hole, and pulled the grill
+back into its slot behind him.</p>
+
+<p>Somewhere far away he heard a throbbing of giant pumps. There was a rush
+of cool fresh air past his cheek, cold when it contacted the sweat
+pouring down his forehead. He could not quite stand up, but there was
+plenty of room for him to crouch and move.</p>
+
+<p>Ahead of him was a black tunnel, broken only by a patch of light coming
+through the grill that opened into the next compartment. He started into
+the blackness, his heart racing.</p>
+
+<p>Somewhere in the ship Johnny Coombs and Greg Hunter were
+prisoners ... but now, Tom knew, there was a way to escape.</p>
+
+<hr style='width: 45%;' />
+
+<p>It was a completely different world, a world within a world, a world of
+darkness and silence, of a thousand curving and intersecting tunnels,
+some large, some small. For hours it seemed to him that he had been
+wandering through a tomb, moving through the corridors of a dead ship,
+the lone surviving crewman. There was some contact with the other world,
+of course, the world of the spaceship outside ... each compartment had
+its metal grill, and he passed many of them. But there were like doors
+that only he knew existed. He met no one in <i>these</i> corridors, there was
+no danger of sudden discovery and arrest in these dark alleys....</p>
+
+<p>His boots had made too much noise as he started out, so he had slipped
+them off, hanging them from his belt and moving on in his stocking feet.
+As he went from duct to duct, he had an almost ridiculous feeling of
+freedom and power. In every sense, he was an invisible man. Not one soul
+on this great ship knew he was here, or even suspected. He had the run
+of the ship, complete freedom to go wherever he chose. He could move
+from compartment to compartment as silently and invisibly as if he had
+no substance at all.</p>
+
+<hr style='width: 45%;' />
+
+<p>He knew the first job was to learn the pattern of the ducts, and
+orientation was a problem. He had heard stories of men getting lost in
+the deep underground mining tunnels on Mars, wandering in circles for
+days until their food gave out and they starved. And there was that
+hazard here, for every duct looked like every other one.</p>
+
+<p>But there was a difference here, because the ducts curved just as the
+main ship's corridors did. He could always identify the center of the
+ship by the force of false gravity pulling the other way. Furthermore,
+as the ducts drew closer to the pumps and reconditioning units, they
+opened into larger vents, and the noise of the pumps thundered in his
+ears. After an hour of exploration, Tom was certain that from any place
+in the ship he could at least find his way to the outer layer, and from
+there to one of the scout-ship airlocks.</p>
+
+<p>Finding Greg and Johnny was quite a different matter.</p>
+
+<p>He could not see enough through the compartment grills to identify just
+what the compartments were; he was forced to rely on what he could hear.
+The engine rooms were easily identified. In one area he heard the
+banging of pots and pans, the steaming of kettles ... obviously the
+galley. He found the control area. He could hear the clatter of typing
+instruments, the <i>click-click-click</i> of the computers working out the
+orbits and trajectories for the scout-ships as they moved out from the
+orbit-ship or came back in. In another compartment he heard a dispatcher
+chattering his own special code-language into a microphone in a
+low-pitched voice. He passed another grill, and then stopped short as a
+familiar voice drifted through.</p>
+
+<p>Merrill Tawney's voice.</p>
+
+<p>Tom hugged the grill, straining to catch the words. The company man
+sounded angry; the man he was talking to sounded even angrier. "I can't
+help what you want or don't want, Merrill, I can only report what we've
+found, and that's nothing at all. Every one of those claims has been
+searched twice over. Doc and his boys went over them, and we didn't find
+anything they missed. I think you're barking up the wrong tree."</p>
+
+<p>"There's <i>got</i> to be something," Tawney said, his voice tight with
+anger. "Hunter couldn't have taken anything away from there, he didn't
+have a chance to. You read the reports..."</p>
+
+<p>"I know," the other said wearily, "I know what the reports said."</p>
+
+<p>"Then what he found is still there. There's no other possibility,"
+Tawney said.</p>
+
+<p>"We went over that rock with a microscope. We blew it to shreds. Assay
+has gone through the fragments literally piece by piece. They found low
+grade iron, a trace of nickel, a little tin, and lots of granite. If we
+never found anything richer than that, we'd have been out of business
+ten years ago."</p>
+
+<p>There was a long silence. Tom pressed closer to the grill. Then he heard
+Tawney slam his fist into his palm. "You know what Roger Hunter's doing,
+don't you?" he said. "He's making fools of us, that's what! The man's
+dead, and he's making us look like idiots. If we hadn't been so sure we
+had the lode spotted ..." He broke off. "Well, that's done, we can't
+undo it. But this brat of his...."</p>
+
+<p>"Any luck there?"</p>
+
+<p>"Not a word. He's playing coy."</p>
+
+<p>"Maybe he doesn't know anything. Doc made a bad mistake when he blasted
+the other one ... suppose <i>he</i> was the only one that knew."</p>
+
+<p>"All right, it was a mistake," Tawney snapped. "What was he supposed to
+do, let him get back to Mars? We've got a good front there, but it's not
+that good. If the United Nations gets a toehold out here, the whole Belt
+will go into their pocket, you realize that. They're waiting for us to
+make one slip." He paused, and Tom heard him pacing the compartment.
+"But I think we've got our boy. This one knows. We've been spoiling him
+so far, that's all. Well, now we start digging. When I get through with
+him, he'll be begging us to let him tell. You just watch me, as soon as
+the okay comes through...."</p>
+
+<p>Tom drew back from the grill, moving on in the darkness. So far he had
+not rushed his exploration ... there was a chance to use the ducts for
+escape, he wanted to know them well. But now he knew the hour was
+getting late. So far Greg and Johnny had been stalling Tawney ... but
+Tawney was getting impatient.</p>
+
+<p>He moved quickly and he thought again of what Tawney had said. Tawney
+was right about one thing ... there was no way that Dad could have
+hidden a Big Strike so nobody could find it. It had to be there....</p>
+
+<p>And yet it wasn't. He and Greg hadn't found it. Tawney's men hadn't
+found it, either. Why not? There must be a reason.</p>
+
+<p>But he could not put his finger on it.</p>
+
+<p>Half an hour later he was seriously worried. Half the compartments in
+the area were deserted, the men leaving for the cafeteria. The thought
+reminded Tom how hungry he was, and thirsty. His small emergency ration
+kit was empty. He toyed with the thought of sneaking into a food storage
+compartment, then thrust it out of his mind as too risky. He had to find
+Greg and Johnny before anything.</p>
+
+<p>He passed a grill, and heard a murmur of voices; something in the deep
+bass rumble caught his ear, and he stopped, listened.</p>
+
+<p>The voices stopped also.</p>
+
+<p>He waited for them to begin, pressing against the grill. Johnny Coombs
+was not the only man with a deep bass voice, he might have been
+mistaken. He listened, but there was no sound. He heard the whir of a
+fan begin, still no sound, not even footsteps.</p>
+
+<p>And then it happened, so fast he was taken completely off guard. The
+grill suddenly gave way, pitching him forward into the compartment.
+Something struck him behind the ear as he fell; there was a grunt, a
+sharp command, and he was pinned to the floor in the semi-darkness of
+the compartment.</p>
+
+<p>Then he heard a gasp, and he opened his eyes. He was staring into his
+brother's startled face. Greg was pinning his shoulders to the carpeted
+deck, and behind him Johnny Coombs had a fist raised....</p>
+
+<p>But they had stopped in mid-air, like a tableau of puppets. Greg gaped,
+his jaw falling open, and Tom heard himself saying, "What are you trying
+to do, kill a guy? Seems to me one time is enough."</p>
+
+<p>He had found them.</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="c10_The_Trigger" id="c10_The_Trigger"></a>10. The Trigger</h2>
+
+
+<p>In the first instance of astonishment they were speechless. Later, Tom
+said it was the first time in his life that he had ever seen Greg
+totally without words; his brother jumped back, as if he had seen a
+ghost, and his mouth worked, but no sounds came out.</p>
+
+<p>"Don't worry, it's me all right," Tom said, "and I'm mighty hungry."</p>
+
+<p>Greg and Johnny stared at the black hole behind the grill ... and then
+Greg was pumelling him, pounding him on the back, so excited he couldn't
+get a sentence out, and Johnny was hovering over them, incredulous but
+forced to believe his eyes, like a father overwhelmed by the impossible
+behavior of a pair of unpredictable children. It was a jubilant reunion.
+They broke open the cabinets and refrigerator in the back of the lounge
+and pulled out surro-ham and rolls, while Johnny got some coffee going.
+Tom was so famished he could hardly wait to make sandwiches of the ham.
+He ate it as fast as he got it.</p>
+
+<p>But finally he slowed up, got his mouth empty enough to talk. "All
+right, let's have the story," Greg said, still looking as though he
+couldn't believe his eyes. "The last we saw, you were blown into atoms
+out there in that <i>Scavenger</i> ... you've got some nerve turning up now
+and scaring us half out of our skins...."</p>
+
+<p>"You want me to go back in my hole?"</p>
+
+<p>"Just sit still and talk!"</p>
+
+<p>Tom told them, then, starting from the beginning.</p>
+
+<p>Through it all Greg stared in admiration. "We've got a genius among us,
+that's all," he said finally. "And I always thought you were the timid
+one...."</p>
+
+<p>"But what else could I do?" Tom said. "You know what they say about
+grabbing a tiger by the tail ... once you get hold, you've got to hold
+on."</p>
+
+<p>"Okay," Greg said, "but the next time I make a crack about your retiring
+nature, remind me to stick my foot in my mouth."</p>
+
+<p>"I'll do it for him," Johnny Coombs rumbled.</p>
+
+<p>Tom nodded toward the open grill. "The only thing I don't see is how you
+knew I was back there."</p>
+
+<p>Johnny grinned. "We were busy taking down the grill when you came
+along. We'd found three microphones in this place, and figured they
+might have one behind the grill. And then we heard somebody breathing
+back there ... we thought they'd posted a guard back there, just to snoop
+us."</p>
+
+<p>"Well, I'm glad you didn't hit him any harder...."</p>
+
+<p>Johnny started to say something, then stopped, cocked his head toward
+the door. There were footsteps in the corridor outside; they came
+closer, stopped by the door. "Quick," Johnny hissed, "back inside!"</p>
+
+<p>There was no time to look for other concealment. Tom leaped across the
+room, jumped up into the shaft again, and Greg slammed the grate up into
+place just as the hatchway door swung open.</p>
+
+<p>Merrill Tawney walked into the room, with two burly guards behind him.</p>
+
+<hr style='width: 45%;' />
+
+<p>For the first few seconds, Greg was certain that they were lost. He
+stood with his back to the ventilator grill, frozen in his tracks as the
+fat little company man came in the room. He tried to keep his face
+blank, but he knew he wasn't succeeding. He saw the puzzled frown form
+on Tawney's face.</p>
+
+<p>The company man motioned the guards into the room, peered suspiciously
+at Greg and Johnny. "Am I interrupting something, by any chance?"</p>
+
+<p>"Nothing at all," Johnny blurted. "We were just talking."</p>
+
+<p>"Talking." Tawney repeated the word as if it were some strange language
+he didn't quite understand. He looked at the guard. "Let's just check
+them."</p>
+
+<p>While one guard patted down their clothes, the other withdrew a stunner,
+held it on ready. Tawney prowled the lounge. He glanced at the food on
+the table, then reached under the chair cushion and withdrew the
+disconnected microphone, looked at the loose wires, and tossed it aside.</p>
+
+<p>"They're clean," the guard said.</p>
+
+<p>Tawney's face was a study of uneasiness, but he clearly could not
+pinpoint what the trouble was. Finally he shrugged, turned on the smile
+again, although his eyes remained watchful. "Well, maybe you won't mind
+if I join in the talking for a while," he said. "You've been
+comfortable? No complaints?"</p>
+
+<p>"No complaints," Greg said.</p>
+
+<p>"Then I presume we're ready to talk business." He looked at Greg.</p>
+
+<p>"You said you were ready to bargain," Greg said, "but I haven't heard
+any terms yet."</p>
+
+<p>"Terms? Very simple. You direct us to the lode, we give you half of
+everything we realize from it," Tawney said, smiling.</p>
+
+<p>"You mean you'll write us a contract? With a U.N. witness to it?"</p>
+
+<p>"Well, hardly ... under the circumstances. I'm afraid you'll have to
+take our word."</p>
+
+<p>Greg looked at the company man, and shook his head. "Not that I don't
+trust you," he said, "but I'm afraid I can't give you what you want,"
+Greg said.</p>
+
+<p>"Why not?"</p>
+
+<p>"Because I don't know where Dad made his strike."</p>
+
+<p>The company man's face darkened. "Somebody knows where it is. Your
+father would never have found something like that without telling his
+own sons...."</p>
+
+<p>"Sorry," Greg said. "Of course, I can tell you where you can find out,
+if you want to go look."</p>
+
+<p>"We've already searched his records...."</p>
+
+<p>"<i>Some</i> of his records," Greg said. "Not all of them. There was a
+compartment behind the main control panel in Dad's orbit-ship. Dad used
+it to store deeds, claims, other important papers. There was a packet of
+notes in there before your men fired on the ship. But of course, maybe
+you searched more thoroughly, the second time."</p>
+
+<p>Tawney stared at him for a moment, then at Johnny. Johnny Coombs
+shrugged his shoulders solemnly, and shook his head. Without a word, the
+little company man walked to the intercom speaker on the wall. He spoke
+sharply into it, waited, then had a brief, pungent conversation with
+someone. Then he turned back to Greg, his face heavy with suspicion.
+"You saw these papers?"</p>
+
+<p>"Certainly I saw them. I didn't have time to read them through, but what
+else could they be?"</p>
+
+<p>"Let me warn you," Tawney said coldly, "if I send a crew out there on a
+wild goose chase, the party will be over when they get back, do you
+understand? You've been given every consideration. If this is a fool's
+errand, you'll pay for it very dearly." He turned on his heel, snarled
+at one of the guards. "I want them watched every minute," he said. "One
+of you stay with them constantly. It won't take long to find out if this
+is a stall...."</p>
+
+<p>He stalked out, and the hatchway clanged behind him. One guard went
+along; the big one with the stunner stayed behind, eyeing his prisoners
+unpleasantly. The stunner was in his hand, the safety off.</p>
+
+<p>Johnny Coombs started across the room toward the kitchennette, passing
+close to the guard. Suddenly he turned, swung his fist heavily down on
+the guard's neck. The stunner crackled, but Greg had jumped aside.
+Another blow from Johnny's fist sent the gun flying. Another blow, and
+the guard's legs slid out from under him. He fell unconscious to the
+floor.</p>
+
+<p>In an instant they were across the room, lifting down the grill, helping
+Tom out of his hiding place. "Okay, boy," Johnny said to Greg, "I guess
+you pulled the trigger with that story of yours."</p>
+
+<p>"Not me," Greg said. "Tom did. He's the one that showed us the way
+out ... the same way he came in."</p>
+
+<hr style='width: 45%;' />
+
+<p>The guard was out for a while, they made sure of that first. Then there
+was a hasty consultation. "The airlocks are guarded," Johnny said, "and
+if they tumble to the ventilator shafts, they can smoke us out in no
+time. How are we going to get a scout-ship without showing ourselves?
+For that matter, how are we going to get a scout-ship away from here
+without being blown up the way the <i>Scavenger</i> was blown up?"</p>
+
+<p>"I think I know a way," Tom said. "We have to have something to keep a
+lot of the crew busy. If we could get to the ship's generators and put
+them out of commission somehow, it might do it."</p>
+
+<p>"Why?" Greg wanted to know.</p>
+
+<p>"Because of the air supply," Tom said. "Without the generators, the fans
+won't run. They'll have to get a crew to fix them or they'll suffocate."</p>
+
+<p>"But that would only take a few men," Johnny said. "As soon as
+the generators went out, they'd look for us, and if we were
+missing ... well, they'd have the whole crew beating the bushes for us.
+It wouldn't be long before somebody thought of the ventilators."</p>
+
+<p>"But we've got to do something, and do it fast," Tom said.</p>
+
+<p>"I know." Johnny chewed his lip. "It's a good idea, but we need more
+than just the generators. We've got to disable the ship ... throw so
+many things at them so fast from so many different directions that they
+don't know which way to turn. That means we'd need to split up, and we'd
+need weapons." He hefted the guard's Markheim. "One stunner between
+three of us isn't enough."</p>
+
+<p>"Well, we have this." Tom unbuckled Roger Hunter's gun case from his
+belt. "Dad's revolver. It's not a stunner, but it might help." He tossed
+the case to Johnny. "I can give you both a rundown on how the shafts go.
+We could plan to meet at a certain spot in a certain length of time...."</p>
+
+<p>He broke off, looking at Johnny. The big miner had taken Roger Hunter's
+gun from the case, and hefted it in his hand, started to check it
+automatically as Tom talked. But now his hand froze as he stared at the
+weapon.</p>
+
+<p>"What's wrong?" Tom asked.</p>
+
+<p>"This gun is wrong," Johnny said. "All wrong. Where did you get this
+thing?"</p>
+
+<p>"From Dad's spacer pack, the one the Patrol brought back. The Major gave
+it to us in Sun Lake City." Tom peered at the gun. "Is it broken or
+something? It's just Dad's revolver...."</p>
+
+<p>"It is, eh?" Johnny turned the gun over in his hand. "Whoever told you
+about guns?"</p>
+
+<p>"What's wrong with it?"</p>
+
+<p>There was an odd expression on Johnny's face as he handed the weapon
+back to Tom. "Take a look at it," he said. "Tell me whether it's loaded
+or not."</p>
+
+<p>Tom looked at it. Except for a few hours on the firing range, he had had
+no experience with guns; he couldn't have taken down a Markheim and
+reassembled it if his life depended on it. But he had seen his father
+take the old revolver out of the leather case many times before.</p>
+
+<p>Now Tom could see that this was not the same gun.</p>
+
+<p>The thing in his hand was large and awkward. The hand-grips didn't fit;
+there was no trigger guard, and no trigger. Several inches along the
+gleaming metal barrel was a shiny stud, and below it a dial with notches
+on it.</p>
+
+<p>"That's funny," Tom said. "I've never seen this thing before."</p>
+
+<p>Greg took it from him, balanced it in his hand. "Doesn't feel right," he
+said. "All out of balance."</p>
+
+<p>"Look at the barrel," Johnny said quietly.</p>
+
+<p>Greg looked. There was no hole in the end of the barrel. "This thing's
+crazy," he said.</p>
+
+<p>"And then some," Johnny said. "You haven't had this out of the case
+since you took it from the pack?"</p>
+
+<p>"Just once," said Tom. "And I put it right back. I hardly looked at it.
+Look, maybe it's just a new model Dad got."</p>
+
+<p>"It's no new model. I'm not even sure it's a gun," Johnny said. "Doesn't
+<i>feel</i> like a gun."</p>
+
+<p>"What happens when you push the stud here?" Greg asked.</p>
+
+<p>Johnny licked his lips nervously. "Try it," he said.</p>
+
+<p>Greg leveled the thing at the rear wall of the lounge and pressed the
+stud. There was a sharp buzzing sound, and a blinding flash of blue
+light against the wall. It looked for all the world like the flash of a
+live power line shorting out. They squinted at the flash, rubbed their
+eyes....</p>
+
+<p>And stared at the wall. Or at what was left of the wall, because most of
+the wall was gone. The metal had bellied out in a six-foot hole into the
+storage hold beyond....</p>
+
+<p>Johnny Coombs whistled. "This thing did <i>that</i>?" he whispered.</p>
+
+<p>"It must have...."</p>
+
+<p>"But there's no gun ever made that could do that." He walked over to the
+hole in the wall. "That's half-inch steel plate. There's no way to pack
+that kind of energy into a hand gun."</p>
+
+<p>They stared at the innocent-looking weapon in Greg's hand. "Whatever it
+is, Dad must have put it in the gun-case."</p>
+
+<p>"Yes, he must have," Johnny said.</p>
+
+<p>"Well, don't you see what that means? <i>Dad must have found it
+somewhere</i>. Somewhere out here in the Belt ... a gun that no man could
+have made...."</p>
+
+<p>He took the weapon, ran his finger along the gleaming barrel. "I
+wonder," he said, "what else Dad might have found out there."</p>
+
+<hr style='width: 45%;' />
+
+<p>Somewhere below them they heard a hatch clang shut, and even deeper in
+the ship generator motors began throbbing in a steady even rhythm. In
+the silence of the lounge they could hear their own breathing, and
+outside a thousand tiny sounds of the ship's activity were audible.</p>
+
+<p>But now they had attention only for the odd-shaped piece of metal in
+Greg's hand, and for the hole that gaped in the wall.</p>
+
+<p>"You think that <i>this</i> was what Dad found?" Greg said. "The Big Strike
+he told Johnny about?"</p>
+
+<p>"It must be part of it," Tom said.</p>
+
+<p>"But what is it? And where did it come from? It doesn't make sense,"
+Greg protested.</p>
+
+<p>"It doesn't make sense the way we've been looking at it," Tom said. "All
+we've found was some gobbledegook in Dad's private log to tell us what
+he found ... but it couldn't have been a vein of ore, or Tawney's men
+would have unearthed it. It had to be something else. Something that was
+so big and important that Dad didn't even dare let Johnny in on it."</p>
+
+<p>"Yes, that's been the craziest part of it, to me," Johnny said. "I've
+done a lot of mining with your Dad. If he'd hit rich ore, he would have
+taken me out there to mine it with him. But he didn't. He said it was
+something he had to work on alone for a while, and he sent me back."</p>
+
+<p>"As if he'd found something that scared him," Tom said, "or something
+that he didn't understand. He was <i>afraid</i> to tell anybody. And whatever
+he found, he managed to hide it somewhere, so that nobody would find
+it...."</p>
+
+<p>"Then why didn't he hide this part of it, too?" Greg said.</p>
+
+<p>"Maybe to be sure there was some trace left, if anything happened to
+him," Tom said.</p>
+
+<p>They were silent for a moment. The only sound was the stertorous
+breathing of the unconscious guard. "Well," Greg said finally, "I have
+to admit it makes sense. It makes other things add up better, too. Dad
+was no fool, he must have known that Tawney was onto something. And Dad
+would never have risked his life for an ore strike. He'd either have
+made a deal with Tawney or let him hijack the lode, if that was all
+there was to it. But there's still one big question ... where did he
+hide what he found? And we aren't going to find the answer here." He
+walked over to the hole in the wall.</p>
+
+<p>"Made quite a mess of it, didn't it?" Johnny said.</p>
+
+<p>"Looks like it. I wonder what that thing would do to a ship's generator
+plant." He turned to Johnny. "We haven't much time. With this thing, we
+could tear this ship apart, leave them so confused they'll never know
+what broke loose. And if we could get that gun back to Major Briarton,
+he'd have to listen to us, and get the U.N. Patrol into the search...."</p>
+
+<p>They had been so intent on their talking that they did not hear the
+footsteps in the corridor until the door swung open. It was another
+guard, the one who had departed with Tawney. He stopped short, blinking
+at his companion on the floor, and then at the gaping hole in the wall.
+When he saw the twins, side by side, his jaw sagged and a strangled
+sound came from his throat.</p>
+
+<p>Then Johnny grabbed his arm, jerked him into the lounge, and slammed the
+hatch shut. Greg pulled the stunner from his holster and tossed it to
+Tom. The guard let out a roar, twisted free, and met Johnny's fist as he
+came around. He sagged at the knees and slid to the floor beside the
+other guard. "All right," Johnny said, "we've dealt the cards, now we'd
+better play the hand. Tom, you first."</p>
+
+<p>Tom pulled the ventilator grill down, and climbed up into the shaft.
+Greg followed, with Johnny at his heels, pulling the grill back up into
+place from the inside. They waited for a moment, but there was no sound
+from the lounge.</p>
+
+<p>"All right," Johnny said breathlessly. "Let's move."</p>
+
+<p>Swiftly they started down the dark tunnel.</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="c11_The_Haunted_Ship" id="c11_The_Haunted_Ship"></a>11. The Haunted Ship</h2>
+
+
+<p>They did not pause, even to catch their breath, for the first twenty
+minutes as Tom led them swiftly and silently down through the maze of
+corridors and chutes that made up the ventilation system of the huge
+ship. Greg lost his bearing completely in the first twenty seconds; each
+time his brother paused at a junction of tubes, he felt a wave of panic
+rise up in his throat ... suppose they lost themselves in here! He heard
+Johnny's trousers flapping behind him, saw Tom's figure flit past
+another grill up ahead, and plunged doggedly on.</p>
+
+<p>It was amazingly hard to move quietly. Even in stocking feet they made a
+soft thud with each footfall.</p>
+
+<p>But there was no sign of detection, no sound of alarm. Finally they came
+out into a large shaft which allowed them to stand upright, and they
+stopped to catch their breath.</p>
+
+<p>"Main tube to the living quarters," Tom said when they had caught up to
+him. "Joins with the lower-level tube by a series of chutes. We've
+actually been circumnavigating the ship ... I wanted to get as far away
+from that lounge compartment as possible, in case they check up on you
+right away."</p>
+
+<p>"We can't have much time," Johnny said. "That second guard must have
+been coming to relieve the other, and when the first one doesn't report
+back, they'll smell something fishy."</p>
+
+<hr style='width: 45%;' />
+
+<p>They talked it over for a moment. Johnny had been careful to leave the
+hatchway into the corridor ajar before he climbed into the ventilator
+shaft, and then he had pulled the shaft snugly into place behind him.
+Anyone who came would find two unconscious guards, a burnt-out hole in
+the wall, and the door unlocked.</p>
+
+<p>"We'll hope that he takes things at face value, and assumes we're at
+large in the ship somewhere, for a while at least," Johnny said. "That
+hole in the wall is going to set them back a couple of steps, too."</p>
+
+<p>"But they'll sound the alarm, at least," Tom said.</p>
+
+<p>"You bet they will! They'll have every man on the crew shaking down the
+ship for us. But they may not think of the ventilators until they can't
+find us anywhere else."</p>
+
+<p>"But sooner or later they're bound to think of it."</p>
+
+<p>"That's true," Johnny said. "Unless they keep seeing us in the ship. The
+way I figure it, this crew has been on battle stations plenty of times.
+They'll be able to search the whole ship in half an hour. We're just
+going to have to show ourselves ... at least enough to keep them
+searching."</p>
+
+<p>"Well, what if they do think of the ventilators?" Greg said. "They'd
+still have a time finding us."</p>
+
+<p>"Maybe, but don't underestimate Tawney. He might just mask up his crew
+and flood the tubes with cyanide."</p>
+
+<p>They thought about that for a minute. There was no sound here but their
+own breathing, and the low chug-chug-chug of the pumps somewhere deep in
+the ship. Momentarily they expected to hear the raucous clang of the
+alarm bell, as some crew member or another walked into the lounge and
+found them gone. But so far there was no sign they had been discovered
+missing. "No," Johnny said finally, "if we just hide out in here, and
+hope for a chance at one of the scout ships, they'll find us eventually.
+But we've got three big advantages, if we can figure out how to use
+them. That fancy gun, for one. A way to get around the ship, for
+another ... and the fact that there's one more of us than they count on."
+He flipped on his pocket flash, began drawing lines on the dusty floor of
+the shaft. "My idea is to keep them so busy fighting little fires that
+they won't have a chance to worry about where the big one is."</p>
+
+<p>He drew a rough outline-sketch of the organization of the ship. "This
+look right to you, from what you've seen?" he asked Tom.</p>
+
+<p>"Pretty much," Tom said. "There are more connecting tubes."</p>
+
+<p>"All the better. We want to get the generators with our little toy here
+first. That'll darken the ship, and put the blowers out of commission in
+case they think of using gas. Also, it will cut out their computers and
+missile-launching rigs, which might give us a chance to get a scout-ship
+away in one piece if we could get aboard one."</p>
+
+<p>"All right, the generators are first," Tom said. "But then what? There
+are four hundred men on this ship. They'll have every airlock triple
+guarded. They'll block us for sure."</p>
+
+<p>"Not when we get through, they won't," Johnny grinned. "We've got an old
+friend aboard who's going to help us."</p>
+
+<p>"<i>Friend?</i>"</p>
+
+<p>"Ever hear of panic?" Johnny said. "Just listen a minute."</p>
+
+<p>Quickly then, he outlined his plan. Tom and Greg listened, watched
+Johnny make marks with his finger in the dust. When he finished, Greg
+whistled softly. "You missed your life work," he said. "You should have
+gone into crime."</p>
+
+<p>"If I'd had a ghost to help me, I might have," Johnny said.</p>
+
+<p>"It's perfect," Tom said, "if it works. But it all depends on one
+thing ... keeping it rolling after we start...."</p>
+
+<p>For another five minutes they went over the details. Then Johnny clapped
+them each on the shoulder. "It's up to you two," he said. "Let's go."</p>
+
+<p>They moved down the large shaft to the place where it broke into several
+spurs. Johnny started down the chute toward the engine rooms; Tom and
+Greg headed in opposite directions toward the main body of the ship.
+Just as they broke up, they heard a muffled metallic sound from the
+nearest compartment grill.</p>
+
+<p>It was the <i>clang-clang-clang</i> of the orbit-ship's general alarm.</p>
+
+<hr style='width: 45%;' />
+
+<p>Crewmen stopped with food halfway to their mouths, jerked away from
+tables. Orders buzzed along a dozen wires, and section chiefs began
+reporting their battle-stations alert and ready. Finally Tawney snapped
+on the general public address system speaker. "Now get this," he roared.
+"I want every inch of this ship searched ... every corridor, every
+compartment. I want a special crew standing by for missile launching.
+I want double guards at every airlock. If they get a ship away from
+here, the man who lets them through had better be dead when I find
+him...." He broke off, clutching the speaker until his voice was under
+control again. "All right, move. They're armed, but there's no place they
+can go. Find them."</p>
+
+<p>A section-chief came back over the speaker. "Dead or alive, boss?"</p>
+
+<p>"Alive, you idiot! At least the Hunter brat. I'll take the other one any
+way you can get him."</p>
+
+<p>He switched off, and waited, pacing the control cabin like a caged
+animal. Ten minutes later a buzzer sounded. "Hydroponics, boss. All
+clear."</p>
+
+<p>"No sign of them?"</p>
+
+<p>"Nothing."</p>
+
+<p>Another buzz. "Number seven ore hold. Nothing here."</p>
+
+<p>Still another buzz. "Crew's quarters. Nothing, boss."</p>
+
+<p>One by one the reports came in. Fuming, Tawney checked off the sections,
+watched the net draw tighter throughout the ship. They were somewhere,
+they <i>had</i> to be....</p>
+
+<p>But nobody seemed to find them.</p>
+
+<p>He was buzzing for his first mate when the power went off. The lights
+went out, the speaker went dead in his hand. The computers sighed
+contentedly and stopped computing. Abruptly the emergency circuits went
+into operation, flooding the darkness with harsh white lights. The
+intercom started buzzing again.</p>
+
+<p>"Engine room, boss."</p>
+
+<p>"What happened down there?" Tawney roared.</p>
+
+<p>The man sounded like he'd just run the mile. "Generators," he panted.
+"Blown out."</p>
+
+<p>"Well, get somebody in there to fix them. Have a crew seal off the
+area...."</p>
+
+<p>"Can't, boss. Fix them, I mean."</p>
+
+<p>"Why not? What have we got electricians for?"</p>
+
+<p>"There's nothing left to fix. The generators aren't wrecked ... they're
+demolished...."</p>
+
+<p>"Then get the pair that did it...."</p>
+
+<p>"They're not here. We've been sealed up tight. There's no way anybody
+could have gotten in here...."</p>
+
+<p>After that, things began to get confusing.</p>
+
+<hr style='width: 45%;' />
+
+<p>For a while Merrill Tawney thought that his crew was going crazy ... and
+then he began to wonder if he were the one who was losing his mind.</p>
+
+<p>Whatever the case, Merrill Tawney was certain of one thing. The things
+that were happening on his orbit-ship could not possibly be happening.</p>
+
+<p>A guard in one of the outer shell storage holds called in with a
+disquieting report. Greg Hunter, it seemed, had just been spotted
+vanishing into one of the storage compartments from the main outer-shell
+corridor. When the guard had broken through the jammed hatchway to
+collar his trapped victim, there was no sign of the victim anywhere
+around.</p>
+
+<p>At the same moment, a report came in from a guard on the opposite side
+of the ship. He had just spotted Greg Hunter <i>there</i>, it seemed, moving
+down a spur corridor. The guard had held his fire (according to Tawney's
+orders) and summoned help to corner the quarry ... but when help
+arrived, the quarry had vanished.</p>
+
+<hr style='width: 45%;' />
+
+<p>Five minutes later the Hunter boy was discovered in the Hydroponics
+section, busily reducing all the yeast vats to shambles with a curious
+weapon that seemed to eat holes in things. It ate the deck out from
+under the guard's feet, sending him plunging through the floor into the
+galley. By the time he had scrambled back again, the Hunter boy was
+gone, and a rapid move to seal off the region failed to turn him up
+again. The guard was upset; Tawney was a great deal more upset, because
+at the time Greg Hunter was (reportedly) playing havoc with the
+yeast-vats in Hydroponics he was also (reportedly) knocking guards down
+like ten-pins in the main corridor off the engine room while
+reinforcements tried to pin him down with a wide-beam stunner....</p>
+
+<p>Quite suddenly emergency circuits closed and lights flashed in the
+control cabin, the special signal for a meteor-collision with the outer
+shell in No. 3 hold. Tawney signalled for the section chief frantically.
+"What's happening down there?"</p>
+
+<p>"I can't talk," the section chief gasped. "Gotta get into a suit, we're
+leaking in here...."</p>
+
+<p>"Well, plug up the hole!"</p>
+
+<p>"The hole's four feet wide, sir!" There was a fit of coughing and the
+contact broke. The signals for No. 4 hold and No. 5 hold were flashing
+now; while the crew members in the vicinity scrambled for pressure suits
+someone systematically proceeded to blow holes in No. 9, No. 10 and No.
+11 holds....</p>
+
+<p>It was impossible. The reports came in thick and fast. Greg Hunter
+was in two places at once, and everywhere he went ... in both
+places ... there was a trail of unbelievable destruction. Bulkheads
+demolished, gaping holes torn in the outer shell, the air-reconditioning
+units smashed beyond repair.... Tawney buzzed for his first mate.</p>
+
+<p>An emergency switch cut into the line, with the frantic voice of a
+section chief. Johnny Coombs had been spotted disappearing into the
+ventilator shaft in the engine sector. "Well, go in after him!" Tawney
+screamed. He got his first mate finally, and snarled orders into the
+speaker. "They're in the ventilators. Get a crew in there and stop
+them."</p>
+
+<p>But it was dark in the ventilator shafts. No emergency lights in there.
+Worse, the crewmen were hearing the things that were being whispered
+around the ship. The ventilator shafts yawned menacingly before them;
+they went in reluctantly. Once in the dark maze of tunnels,
+identification was difficult. Two guards met each other headlong in the
+darkness, and put each other out of the fight in a flurry of nervous
+stunner-fire. While they searched more of the holds were broken open,
+leaking air through gaping rents in the hull....</p>
+
+<p>Tawney felt the panic spreading; he tried to curb it, and it spread in
+spite of him. The fugitives were appearing and disappearing like
+wraiths. Reports back to control cabin took on a frantic note, confused
+and garbled. Now the second-level bulkheads were being attacked. Over a
+third of the compartments were leaking precious air into outer space.</p>
+
+<p>When a terrified section chief came through with a report that two Greg
+Hunters had been spotted by the same man at the same time, and that the
+guards in the sector were shooting at anything that moved, including
+other guards, Tawney made his way to the radio cabin and put through a
+frantic signal to Jupiter Equilateral headquarters on Mars.</p>
+
+<p>The contact took forever, even with the ship's powerful emergency
+boosters. By the time someone at headquarters was reading him, Tawney's
+report sounded confused. He was trying for the third time to explain,
+clearly and logically, how two men and a ghost were scuttling his
+orbit-ship under his very feet when one wall of the cabin vanished in a
+crackle of blue fire, and he found himself staring at two Greg Hunters
+and a grim-faced Johnny Coombs.</p>
+
+<p>He made squeaky noises into the microphone and dropped it with a crash.
+He groped for a chair; Johnny jerked him to his feet again. "A
+scout-ship," he said tersely. "Clear it for launching. We want one with
+plenty of fuel, and we don't want a single guard anywhere near the
+airlock." He picked up an intercom microphone and thrust it into the
+little fat man's trembling hand. "Now move! And you'd better be sure
+they understand you, because you're coming with us."</p>
+
+<p>Merrill Tawney stared first at Tom, then at Greg, and finally at the
+microphone. Then he moved. The orders he gave to his section chiefs were
+very clear and concise.</p>
+
+<p>He had never argued with a ghost before, and he didn't care to start
+now.</p>
+
+<hr style='width: 45%;' />
+
+<p>It was over so quickly that it seemed to Tom it had just begun, and if
+so much had not been at stake, it might have been fun.</p>
+
+<p>It had been the gun ... the remarkable gun that Roger Hunter had left as
+his legacy ... that had been the key. It ate through steel and aluminum
+alloy like putty. Whatever its power source, however it worked, by
+whatever means it had been built, there had been no match for it on the
+orbit-ship.</p>
+
+<p>It had <i>worked</i> ... and that was all that mattered right then.</p>
+
+<p>With it, and with the advantage of a ghost that walked like a
+man ... Tom Hunter, to be exact ... they had reduced the Jupiter
+Equilateral orbit-ship to a smoking wreck in something less than thirty
+minutes.</p>
+
+<p>The signal came back that a scout-ship was ready, unguarded. Johnny
+prodded Tawney with the stunner. "You first," he said.</p>
+
+<p>"But where are you taking me?"</p>
+
+<p>"You'll see," Johnny said.</p>
+
+<p>"It was a trick," Tawney said, glaring at Tom. "They told me they shot
+your ship to pieces...."</p>
+
+<p>"The ship, yes," Tom said. "Not me."</p>
+
+<p>"Well ... well, that's good, that's good," Tawney said quickly. He
+turned to Greg. "You don't have to take me back ... the bargain is still
+good...."</p>
+
+<p>"Move," Johnny Coombs said.</p>
+
+<p>With Tawney between them, Greg and Tom marched down the corridor toward
+the airlock, with Johnny bringing up the rear. No one stopped them. No
+one even came near them. One crewman stumbled on them in the corridor;
+he saw Tawney with a gun in his back, and fled in terror.</p>
+
+<p>They found the scout-ship, and strapped Tawney down to an accelleration
+bunk, binding his hands and feet so he couldn't move. Greg checked the
+controls while Tom and Johnny strapped down. A moment later the engines
+fired, and the leaking wreck of the orbit-ship fell away, dwindling and
+disappearing in the blackness of space.</p>
+
+<p>It was a quiet journey. The red dot that was Mars grew larger every
+hour. One of the three stayed awake at all times to watch Tawney while
+the others slept. During the second rest period, Tom woke up while Greg
+was on duty.</p>
+
+<p>"How's our prisoner doing?" Tom asked.</p>
+
+<p>"No problem there, he can barely move. I almost wish he'd try something,
+he's too quiet."</p>
+
+<p>It was true. Tawney had recovered from his shock ... but rather than
+grow more worried as Mars grew large on the screen, he seemed to become
+more cheerful by the minute. "He doesn't seem very worried, does he?"
+Tom said.</p>
+
+<p>"No, and it doesn't quite add. We've got enough on him to get Jupiter
+Equilateral pushed right out of the Belt."</p>
+
+<p>"I'd still feel better if we had the whole picture for the Major," Tom
+said. "We still don't know what Dad found, or where he hid it...."</p>
+
+<p>The uneasiness grew. Tawney ignored them, staring at the image of the
+red planet on the viewscreen almost eagerly. Then, eight hours out of
+Sun Lake City a U.N. Patrol ship appeared, moving toward them swiftly.
+"Intercepting orbit," Greg said. "Looks like they were waiting for us."</p>
+
+<p>They watched as the big ship moved in to tangential orbit, matching its
+speed to theirs. Then Greg snapped the communicator switch. "Sound off,"
+he said cheerfully. "We've got a prize for you."</p>
+
+<p>"Stand by, we're boarding you," the Patrol sent back. "And put your
+weapons aside."</p>
+
+<p>Four scooters broke from the side of the Patrol ship. Greg activated the
+airlock. Five minutes later a man in Patrol uniform with captain's bars
+stepped into the control cabin, a stunner on ready in his hand. Three
+Patrolmen came in behind him.</p>
+
+<p>The captain looked around the cabin, then saw Tawney, and took a deep
+breath. "Well, thank the stars you're safe at any rate. Pete, Jimmy,
+take the controls."</p>
+
+<p>"Hold on," Greg said. "We don't need a pilot."</p>
+
+<p>The Captain looked at him. "Sorry, but we're taking you in. There won't
+be any trouble unless you make it. You three are under arrest, and I'm
+authorized to make it stick if I have to. I suggest you just cooperate."</p>
+
+<p>They stared at him. Then Johnny said, "What are the charges?"</p>
+
+<p>"You ought to know," the Captain said. "We have a formal complaint from
+the main offices of Jupiter Equilateral, charging you with piracy,
+murder, kidnapping of a company official, and totally wrecking a company
+orbit ship. I don't quite see how you managed it, but we're going to
+find out in short order."</p>
+
+<p>There was a stunned silence in the cabin, and then a sound came from the
+rear of the cabin.</p>
+
+<p>Merrill Tawney was laughing.</p>
+

+
+
+<p>They were taken to a small, drab internment room. A half hour passed and
+still no word from the Major. From the moment the Patrol crew had
+boarded them, everything had seemed like a bad dream. The shock of the
+arrest, the realization that the Captain had been serious when he reeled
+off the charges lodged against them ... they had been certain it was
+some kind of ill-planned joke until they saw the delegation of Jupiter
+Equilateral officials waiting at the port to greet Merrill Tawney like a
+man returned from the dead. They had watched Tawney climb into the sleek
+company car and drive off toward the gate, while the Captain had
+escorted them without a word down to the internment rooms.</p>
+
+<p>The door clicked, and the Captain looked in. "All right, come along
+now," he said.</p>
+
+<p>"Is the Major here?" Tom said.</p>
+
+<p>"You'll see the Major soon enough." The Captain herded them into another
+room, where a clerk efficiently fingerprinted them. Then they went down
+a ramp to a jitney-platform, and boarded a U.N. official car. The trip
+into the city was slow; rush-hour traffic from the port was heavy. When
+they reached U.N. headquarters, there was another wait in an upper
+level ante-room. The Captain stood stiffly with his hands behind his
+back and ignored them.</p>
+
+<p>"Look, this is ridiculous," Greg burst out finally. "We haven't done
+anything. You haven't even let us make a statement."</p>
+
+<p>"Make your statement to the Major. It's his headache, not mine, I'm
+happy to say."</p>
+
+<p>"But you let that man walk out of there scot free...."</p>
+
+<p>The Captain looked at him. "If I were you," he said, "I'd stop
+complaining and start worrying. If I had Jupiter Equilateral at my
+throat, I'd worry plenty, because once they start they don't stop."</p>
+
+<p>A signal light blinked, and he took them downstairs. Major Briarton was
+behind his desk; his eyes tired, his face grim. He dismissed the
+Captain, and motioned them to seats. "All right, let's have the story,"
+he said, "and by the ten moons of Saturn it had better be convincing,
+because I've about had my fill of you three."</p>
+
+<p>He listened without interruption as Tom told the story, with Greg and
+Johnny adding details from time to time. Tom told him everything, from
+the moment they had blasted off for Roger Hunter's claim to the moment
+the Patrol ship had boarded them, except for a single detail.</p>
+
+<p>He didn't mention the remarkable gun from Roger Hunter's gun case. The
+gun was still in the spacer's pack he had slung over his shoulder; he
+had not mentioned it when the Patrolmen had taken their stunners away.
+Now as he talked, he felt a twinge of guilt in not mentioning it....</p>
+
+<p>But he had a reason. Dad had died to keep that gun secret. It seemed
+only right to keep the secret a little longer. When he came to the part
+about their weapons, he simply spoke of "Dad's gun" and omitted any
+details.</p>
+
+<p>And through the story, the Major listened intently, interrupting only
+occasionally, pulling at his lip and scowling.</p>
+
+<p>"So we decided that the best way to convince you that we had the
+evidence you wanted was to bring Tawney back with us," Tom concluded.</p>
+
+<p>"A brilliant maneuver," the Major said dryly. "A real stroke of genius."</p>
+
+<p>"But then the Patrol ship intercepted us and told us we were under
+arrest. And when we landed, they let Tawney drive off without even
+questioning him."</p>
+
+<p>"The least we could do, under the circumstances," the Major said.</p>
+
+<p>"Well, I'd like to know why," Greg broke in bitterly. "Why pick on us?
+We've just been telling you...."</p>
+
+<p>"Yes, yes, I heard every word of it," the Major sighed. "If you knew the
+trouble ... oh, what's the use? I've spent the last three solid hours
+talking myself hoarse, throwing in every bit of authority I could
+muster and jeopardizing my position as Coordinator here, for the sole
+purpose of keeping you three idiots out of jail for a few hours."</p>
+
+<p>"Jail!"</p>
+
+<p>"That's what I said. The brig. The place they put people when they don't
+behave. You three are sitting on a nice, big powder keg right now, and
+when it blows I don't know how much of you is going to be left."</p>
+
+<p>"Do you think we're lying?" Greg said.</p>
+
+<p>"Do you know what you're charged with?" the Major snapped back.</p>
+
+<p>"Some sort of nonsense about piracy...."</p>
+
+<p>"Plus kidnapping. Plus murder. To say nothing of totally disabling a
+seventeen-million-dollar orbit-ship and placing the lives of four
+hundred crewmen in jeopardy." The Major picked up a sheet of paper from
+his desk. "According to Merrill Tawney's statement, the three of you
+hijacked a company scout-ship that chanced to be scouting in the
+vicinity of your father's claim. Your attack was unprovoked and violent.
+Everybody on Mars knows you were convinced that Jupiter Equilateral was
+responsible for your father's death." He looked up. "In the absence of
+any evidence, I might add, although I did my best to tell you that." He
+rattled the report-sheet. "All right. You took the scout-ship by force,
+with the pilot at gunpoint, and made him home in on his orbit-ship. Then
+you proceeded to reduce that orbit-ship to a leaking wreck, although
+Tawney tried to reason with you and even offered you amnesty if you
+would desist. By the time the crew stopped shooting each other in the
+dark ... fifteen of them subsequently expired, it says here ... you had
+stolen another scout-ship and kidnapped Tawney for the purpose of
+extorting a confession out of Jupiter Equilateral, threatening him with
+torture if he did not comply...." The Major dropped the paper to the
+desk.</p>
+
+<p>Johnny Coombs picked it up, looked at it owlishly, and put it back
+again. "Pretty large operation for three men, Major," he said.</p>
+
+<p>The Major shrugged. "You were armed. That orbit-ship was registered as a
+commercial vessel. It had no reason to expect a surprise attack, and had
+no way to defend itself."</p>
+
+<p>"They were armed to the teeth," Greg said disgustedly. "Why don't you
+send somebody out to look?"</p>
+
+<p>"Oh, I could, but why waste the time and fuel? There wouldn't be any
+weapons aboard."</p>
+
+<p>"Then how do they explain the fact that the <i>Scavenger</i> was blown to
+bits and Dad's orbit-ship ripped apart from top to bottom?"</p>
+
+<p>"Details," the Major said. "Mere details. I'm sure that the company's
+lawyers can muddy the waters quite enough so that little details like
+that are overlooked. Particularly with a sympathetic jury and a judge
+that plays along."</p>
+
+<p>He stood up and ran his hand through his hair. "All right, granted I'm
+painting the worst picture possible ... but I'm afraid that's the way
+it's going to be. I believe your story, don't worry about that. I know
+why you went out there to the Belt and I can't really blame you, I
+suppose. But you were asking for trouble, and that's what you got.
+Frankly, I am amazed that you ever returned to Mars, and how you managed
+to make rubble of an orbit-ship with a crew of four hundred men trying
+to stop you is more than I can comprehend. But you did it. All right,
+fine. You were justified; they attacked you, held you prisoner,
+threatened you. Fine. They'd have cut your throats in another few hours,
+perhaps. Fine. I believe you. But there's one big question that you
+can't answer, and unless you can no court in the Solar System will
+listen to you."</p>
+
+<p>"What question?" Tom said.</p>
+
+<p>"The question of motives," the Major replied. "You had plenty of motive
+for doing what Tawney says you did. But what motive did Jupiter
+Equilateral have, if your story is true?"</p>
+
+<p>"They wanted to get what Dad found, out in the Belt."</p>
+
+<p>"Ah, yes, that mysterious bonanza that Roger Hunter found. I was afraid
+that was what you'd say. And it's the reason that Jupiter Equilateral is
+going to win this fight, and you're going to lose it."</p>
+
+<p>"I don't think I understand," Tom said slowly.</p>
+
+<p>"I mean that I'm going to have to testify against you," the Major said.
+"<i>Because your father didn't find a thing in the Asteroid Belt</i>, and I
+happen to know it."</p>
+
+<hr style='width: 45%;' />
+
+<p>"It's been a war," the Major said later, "a dirty vicious war with no
+holds barred and no quarter given. Not a shooting war, of course,
+nothing out in the open ... but a war just the same, with the highest
+stakes of any war in history.</p>
+
+<p>"It didn't look like a war, at first," the Major went on. "Back when the
+colonies were being built, nobody really believed that anything of value
+would come of them ... scientific outposts, perhaps, places for
+laboratories and observatories, not much more. The colonies were placed
+under United Nations control. Nobody argued about it.</p>
+
+<p>"And then things began to change. There was wealth out here ... and
+opportunities for power. With the overpopulation at home, Earth was
+looking more and more to Mars and Venus for a place to move ... not tiny
+colonies, but places for millions of people. And as Mars grew, Jupiter
+Equilateral grew."</p>
+
+<p>"But it was just a mining company," Tom said.</p>
+
+<p>"At first it was, but then its interests began to expand. The company
+accumulated wealth, unbelievable wealth, and it developed many friends.
+Very soon it had friends back on Earth fighting for it, and the United
+Nations found itself fighting to stay on Mars."</p>
+
+<p>"I don't see why," Tom said. "The company already has half the mining
+claims in the Belt...."</p>
+
+<p>"They aren't interested in the mining," the Major said. "They have a
+much longer-range goal than that. The men behind Jupiter Equilateral are
+looking ahead. They know that someday Earthmen are going to have to go
+to the stars for colonies ... it won't be a matter of choice after a
+while, they'll <i>have</i> to go. Well, Jupiter Equilateral's terms are very
+simple. They're perfectly willing to let the United Nations control
+things on Earth. All they want is control of everything else. Mars, if
+they can drive us out. Venus too, if it ever proves up for colonies. And
+if they can gain control of the ships that leave our Solar System for
+the stars, they can build an empire, and they know it."</p>
+
+<p>They were silent for a moment. Then Johnny Coombs said, "Doesn't anybody
+on Earth know about this?"</p>
+
+<p>"There are some who know ... but they don't see the danger. They think
+of Jupiter Equilateral as just another big company. So far U.N. control
+of Mars and Venus has held up, even though the pressure on the
+legislators back on Earth has been getting heavier and heavier. Jupiter
+Equilateral won the greatest fight in its history when they limited U.N.
+jurisdiction to Mars, and kept us out of the Belt. And now they hope to
+convince the lawmakers that we're incompetent to administer the Martian
+colonies and keep peace out here. If they succeed, we'll be called home
+in nothing flat; we've had to fight just to stay."</p>
+
+<p>The Major spread his hands helplessly. "Like I said, it's been a war.
+Our only hope was to prove that the company was using piracy and murder
+to gain control of the asteroids. We had to find a way to smash the
+picture they've been painting of themselves back on Earth as a big,
+benevolent organization interested only in the best for Earth colonists
+on the planets. We had to expose them before they had the Earth in
+chains ... not now, maybe not even a century from now, but sometime,
+years from now, when the breakthrough to the stars comes and Earthmen
+discover that if they want to leave Earth they have to pay toll...."</p>
+
+<p>"They could never do that!" Greg protested.</p>
+
+<p>"They're doing it, son. And they're winning. We have been searching
+desperately for a way to fight back, and that was where your father came
+in. He could see the handwriting, he knew what was happening. That was
+why he broke with the company and tried to organize a competing force
+before it was too late. And it was why he died in the Belt. He knew I
+couldn't send an agent out there without unquestionable evidence of
+major crime of some sort or another. But a private citizen could go out
+there, and if he happened to be working with the U.N. hand in glove,
+nobody could do anything about it."</p>
+
+<p>"Then Dad was a U.N. agent?"</p>
+
+<p>"Oh, not officially. There's not a word in the records. If I were forced
+to testify under oath, I would have to deny any connection. But
+unofficially, he went out there to lay a trap."</p>
+
+<p>The Major told them then. It had been an incredible risk that Roger
+Hunter had taken, but the decision had been his. The plan was simple: to
+involve Jupiter Equilateral in a case of claim-jumping and piracy that
+would hold up in court, pressed by a man who would not be intimidated
+and could not be bought out. Roger Hunter had made a trip to the Belt
+and come back with stories ... very carefully planted in just the right
+ears ... of a fabulous strike. He knew that Jupiter Equilateral had
+jumped a hundred rich claims in the past, forcing the independent miners
+to agree, frightening them into silence or disposing of them with
+"accidents."</p>
+
+<p>But this was one claim they were not going to jump. The U.N. cooperated,
+helping him spread the story of his Big Strike until they were certain
+that Jupiter Equilateral would go for the bait. Then Roger Hunter had
+returned to the Belt, with a U.N. Patrol ship close by in case he needed
+help.</p>
+
+<p>"We thought it would be enough," the Major said unhappily. "We were
+wrong, of course. At first nothing happened ... not a sign of a company
+ship, nothing. Your father contacted me finally. He was ready to give
+up. Somehow they must have learned that it was a trap. But they had just
+been careful, was all. They waited until our guard was down, and then
+moved in fast and hit hard."</p>
+
+<p>He sank down in his seat behind the desk, regarding the Hunter twins
+sadly. "You know the rest. Perhaps you can see now why I tried to keep
+you from going out there. There was no proof to uncover and no bonanza
+lode for you to find. There never was a bonanza lode."</p>
+
+<p>The twins looked at each other, and then at the Major. "Why didn't you
+tell us?" Greg said.</p>
+
+<p>"Would you have listened? Would telling you have kept you from going out
+there? There was no point to telling you, I knew you would have to find
+out for yourselves, however painfully. But what I'm telling you now is
+the truth."</p>
+
+<p>"As far as it goes," Tom Hunter said. "But if this is really the truth,
+there's one thing that doesn't fit into the picture."</p>
+
+<p>Slowly Tom pulled the gun case from his pack and set it down on the
+Major's desk. "It doesn't explain what Dad was doing with this."</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="c13_Pinpoint_in_Space" id="c13_Pinpoint_in_Space"></a>13. Pinpoint in Space</h2>
+
+
+<p>Tom knew now that it was the right thing to do. There was no question,
+after the Major's story, of what Dad had been doing out in the Belt at
+the time he had been killed. He had been doing a job that was more
+important to him than asteroid mining ... but he had found something
+more important than his own life, and had no chance to send word of what
+he had found back to Major Briarton on Mars. That had been the
+unforeseeable part of the trap.</p>
+
+<p>But now, of course, the Major had to know.</p>
+
+<p>The Mars Coordinator looked at the thing on the desk for a long moment
+before he reached out to touch it. The bright metal gleamed in the
+light, pale gray, lustrous. The Major picked it up, balanced it expertly
+in his hand, and a puzzled frown clouded his face. He examined it
+minutely.</p>
+
+<p>"What is this thing?" he said.</p>
+
+<p>"Suppose you tell us," Johnny Coombs said from across the room.</p>
+
+<p>"It looks like a gun."</p>
+
+<p>"That's what it is, all right."</p>
+
+<p>"You've fired it?"</p>
+
+<p>"Yes ... but I wouldn't fire it in here, if I were you," Johnny said.
+"You were wondering how we wrecked Tawney's orbit-ship so thoroughly.
+That's your answer right there." He told about the hole in the bulkhead,
+the way the ship's generators had melted like clay under the powerful
+blast of the weapon.</p>
+
+<p>The Major could hardly control his excitement. "Where did you get it?"
+he asked, turning to Tom.</p>
+
+<p>"From the space pack that you turned over to us. I didn't even look at
+it, until we needed a gun in a hurry. I just assumed it was Dad's
+revolver."</p>
+
+<p>"And your father found it somewhere in the Belt," the Major said softly.
+He looked at the weapon again, shaking his head. "There isn't any such
+gun," he said finally. "These things you say it could do ... they would
+require energy enough to break down the cohesive forces of molecules.
+There isn't any way we know of to harness that kind of energy and
+channel it in a hand weapon. Nobody on Earth...."</p>
+
+<p>He broke off and stared at them.</p>
+
+<p>"That's right," Johnny said. "Nobody on Earth."</p>
+
+<p>"You mean ... extraterrestrial?"</p>
+
+<p>"There isn't any other answer," Johnny said. "<i>Look</i> at the thing,
+Major. <i>Feel</i> it. Does it feel like it was made for a human hand? It
+doesn't fit, it doesn't balance, you have to hold it with both hands to
+aim it...."</p>
+
+<p>"<i>But where did it come from?</i>" the Major said. "We've never had
+visitors from another star system ... not in the course of recorded
+history. And we know that Earthmen are the only intelligent creatures in
+our Solar System."</p>
+
+<p>"You mean that they're the only ones <i>now</i>," Tom said.</p>
+
+<p>"Or any other time."</p>
+
+<p>"We don't know that, for sure," Tom said.</p>
+
+<p>"Look, we've explored Venus, Mars, all the major satellites. If there
+had ever been intelligence on any of them, we'd have known it."</p>
+
+<p>"Maybe there was a planet that Earthmen haven't explored," Tom said.
+"Even Dad tried to tell us that. The quotation from Kepler that he
+scribbled down in his log ... 'Between Jupiter and Mars I will put a
+planet.' Why would Dad have written that? Unless he had suddenly
+discovered proof that there <i>had</i> been a planet there?"</p>
+
+<p>"You mean this ... this gun," the Major said.</p>
+
+<p>"And whatever else he found."</p>
+
+<p>"But there's never been any proof of that theory ... not even a hint of
+proof."</p>
+
+<p>"Maybe Dad found proof. There are hundreds of thousands of asteroid
+fragments out there in the Belt, and only a few hundred of them have
+ever been examined by men."</p>
+
+<p>On the desk the strange weapon stared up at them. Evidence, mute
+evidence, and yet its very existence said more than a thousand words. It
+was there. It could not be denied.</p>
+
+<p>And someone ... or <i>something</i> ... had made it.</p>
+
+<p>Slowly the Major pulled himself to his feet. "It must have happened
+after his last message to me," he said. "It wasn't part of the scheme we
+had set up, but he made a strike just the same ... an archeological
+strike ... and this gun was part of it." He picked up the weapon, turned
+it over in his hand. "But it was days after that last message before his
+signal went off, and the Patrol ship moved in."</p>
+
+<p>"It makes sense," Johnny Coombs said. "He found the gun, and something
+more."</p>
+
+<p>"Like what?"</p>
+
+<p>"I wouldn't even guess," Johnny said. "A planet with a race of creatures
+intelligent enough and advanced enough to make a weapon like that ... it
+could have been anything. But whatever it was, it must have scared him.
+He must have known that a company ship might turn up any minute ... so
+he hid whatever he had found, and all he dared to leave was a hint."</p>
+
+<p>"And now it's vanished," the Major said. "The big flaw in the whole
+idea. My Patrol ship found nothing when it searched the region. You
+looked, and drew a blank. The company men scoured the area." He spread
+his hands helplessly. "You see, it just won't hold up, not a bit of it.
+Even with this gun, it won't hold up. We've got to find the answer."</p>
+
+<p>"It's out there somewhere," Tom said doggedly. "It's got to be."</p>
+
+<p>"But <i>where</i>? Don't you see that everything hangs on that one thing? If
+we could prove that your father found something just before he was
+killed, we could tear Jupiter Equilateral's case against you into
+shreds. We could charge them with piracy and murder, and make it stick.
+We could break their power once and for all ... but until we know what
+Roger Hunter found, we're helpless. They'll take you three to court, and
+I won't be able to stop them. And if you lose that case, it may mean the
+end of U.N. authority on Mars."</p>
+
+<p>"Then there's just one thing to do," Johnny Coombs said. "We've got to
+find Roger Hunter's bonanza."</p>
+
+<hr style='width: 45%;' />
+
+<p>It was almost midnight when they left the Major's office, a gloomy trio,
+walking silently up the ramp to the Main Concourse, heading toward the
+living quarters.</p>
+
+<p>They had been talking with the Major for hours, going over every facet
+of the story, wracking their brains for the answer ... but the answer
+had not come.</p>
+
+<p>Roger Hunter had found something, and hidden it so well that three
+groups of searchers had failed to discover it. After seeing the gun, the
+Major was convinced that there had indeed been a discovery made. But
+whatever that discovery had been, it was gone as if it had never
+existed ... as if by some sort of magic it had been turned invisible,
+or conjured away to another part of the Solar System.</p>
+
+<p>Finally, they had given up, at least for the moment. "It has to be
+there," the Major had said wearily. "It hasn't vanished, or miraculously
+ceased to exist. We know he was working on one claim, one asteroid.
+There were no other asteroids in the region ... and even the ones within
+suicide radius have been searched."</p>
+
+<p>"It's there, all right," Tom said. "We're missing something, that's
+all."</p>
+
+<p>"But what? Asteroids have stable orbits. Nobody can just make one
+disappear...."</p>
+
+<p>They had called it a night, finally.</p>
+
+<p>Once home they found more bad news waiting. There were two messages on
+the recordomat. The first was an official summons to appear before the
+United Nations Board of Investigations at 9:00 the following morning to
+answer "certain charges placed against the above named persons by the
+Governing Board of Jupiter Equilateral Mining Industries, and by one
+Merrill Tawney, plaintiff, representing said Governing Board." They
+listened to the plastic record twice. Then Greg tossed it down the waste
+chute.</p>
+
+<p>The other message was addressed to Greg, from the Commanding Officer of
+Project Star-Jump. The message was very polite and regretful; it was
+also very firm. The pressure of the work there, in his absence, made it
+necessary for the Project to suspend Greg on an indefinite leave of
+absence. Application for reinstatement could be made at a later date,
+but acceptance could not be guaranteed....</p>
+
+<p>"Well, I might have expected it," Greg said, "after what the Major told
+us. The money for Star-Jump must have been coming from somewhere, and
+now we know where. The company probably figures to lay claim on any
+star-drive that's ever developed." He dropped the notice down the chute,
+and laughed. "I guess I really asked for it."</p>
+
+<p>"You mean I pushed you into it," Tom said bitterly. "If I'd kept my big
+mouth shut at the very start of this thing, you'd have gone back to the
+Project and that would have been the end of it...."</p>
+
+<hr style='width: 45%;' />
+
+<p>Greg looked at him. "You big bum, do you think I really care?" He
+grinned. "Don't feel too guilty, Twin. We've been back to back on this
+one."</p>
+
+<p>He pulled off his shirt and walked into the shower room. Johnny Coombs
+was already stretched out on the sofa, snoring softly.</p>
+
+<p>Quite suddenly the room seemed hot and stuffy, oppressive. He couldn't
+make his thoughts come straight. There had been too much thinking, too
+much speculation. Tom stood up and slipped on his jacket.</p>
+
+<p>He had to walk, to move about, to try to think. He slipped open the
+door, and started for the ramp leading to the Main Concourse.</p>
+
+<p>There was an answer, somewhere.</p>
+
+<p>He walked on along the steel walkways, trying to clear his mind of the
+doubts and questions that were plaguing him. At first he just wandered,
+but presently he realized that he had a destination in mind.</p>
+
+<p>He went up a ramp and across the lobby of the United Nations
+Administration Building. He took a spur off the main corridor, and came
+to a doorway with a small circular staircase beyond it. At the bottom of
+the stairs he opened a steel door and stepped into the Map Room.</p>
+
+<p>It was a small darkened amphitheater, with a curving row of seats along
+one wall. On either side were film viewers and micro-readers. And
+curving around on the far wall, like a huge parabolic mirror, was the
+Map.</p>
+
+<p>Tom had been here many times before, and always he gasped in wonder when
+he saw the awesome beauty of the thing. Stepping into the Map Room was
+like stepping into the center of a huge cathedral. Here was the glowing,
+moving panorama of the Solar System spread out before him in a
+breath-taking three-dimensional image. Standing here before the Map it
+seemed as if he had suddenly become enormous and omnipotent, hanging
+suspended in the blackness of space and staring down at the Solar System
+from a vantage point a million miles away.</p>
+
+<p>Once, Dad had told him, there had been a great statue in the harbor of
+Old New York which had been a symbol of freedom for strangers coming to
+that city from across the sea, and a welcome for countrymen returning
+home. And someday, he knew, this view of the Solar System would be
+waiting to greet Earthmen making their way home from distant stars. The
+Map was only an image, a gift from the United Nations to the colonists
+on Mars, but it reproduced the Solar System in the minutest detail that
+astronomers could make possible.</p>
+
+<p>In the center, glowing like a thing alive, was the Sun, the hub of the
+magnificent wheel. Around it, moving constantly in their orbits, were
+the planets, bright points of light on the velvet blackness of the
+screen. Each orbit was computed and held on the screen by the great
+computer in the vault below.</p>
+
+<p>But there was more on the Map than the Sun and the planets, with their
+satellites. Tiny green lights marked the Earth-Mars and the Earth-Venus
+orbit-ships, moving slowly across the screen. Beyond Mars, a myriad of
+tiny lights projected on the screen, the asteroids. Without the
+magnifier Tom could identify the larger ones ... Ceres, on the opposite
+side of the Sun from Mars now as it moved in its orbit; smaller Juno,
+and Pallas, and Vesta....</p>
+
+<p>For each asteroid which had been identified, and its orbit plotted,
+there was a pinpoint of light on the screen. For all its beauty, the Map
+had a very useful purpose ... the registry and identification of
+asteroid claims among the miners of Mars. Each asteroid registered as a
+claim showed up as a red pinpoint; unclaimed asteroids were white. But
+even with the advances of modern astronomy only a small percentage of
+the existing asteroids were on the map, for the vast majority had never
+been plotted.</p>
+
+<p>Tom moved up to the Map and activated the magnifier. Carefully he
+focussed down on the section of the Asteroid Belt they had visited so
+recently. Dozens of pinpoints sprang to view, both red and white, and
+beneath each red light the claim-number neatly registered. Tom peered at
+the section, searching until he found the number of Roger Hunter's last
+claim.</p>
+
+<p>It was quite by itself, not a part of an asteroid cluster. He stepped up
+the magnification, peered at it closely. There were a dozen other
+pinpoints, all unclaimed, within a ten-thousand-mile radius....</p>
+
+<p>But near it, nothing....</p>
+
+<p>No hiding place.</p>
+
+<p>And then, suddenly, he knew the answer. He stared at the Map, his heart
+pounding in his throat. He cut the magnification, scanning a wide area.
+Then he widened the lens still further, and checked the coordinates at
+the bottom of the viewer.</p>
+
+<p>He knew that he was right. He <i>had</i> to be right. But this was no wild
+dream, this was something that could be proved beyond any question of
+error.</p>
+
+<p>Across the room he picked up the phone to Map Control. It buzzed
+interminably; then a sleepy voice answered.</p>
+
+<p>"The Map," Tom managed to say. "It's recorded on time-lapse film, isn't
+it?"</p>
+
+<p>"'Course it is," the sleepy voice said. "Observatory has to have the
+record. One frame every hour...."</p>
+
+<p>"I've got to see some of the old film," Tom said.</p>
+
+<p>"<i>Now?</i> It's three in the morning."</p>
+
+<p>"I don't need the film itself, just project it for me. There's a reader
+here."</p>
+
+<p>He gave the man the dates he wanted, Mars time. The man broke the
+contact, grumbling, but moments later one of the film-viewers sprang to
+life. The Map coordinates showed at the bottom of the screen.</p>
+
+<p>Tom stared at the filmed image ... the image of a segment of the
+Asteroid Belt the day before Roger Hunter had died.</p>
+
+<p>It was there. When he had looked at the Map, he had seen a single red
+pinpoint of light, Roger Hunter's asteroid, with nothing in the heavens
+anywhere near it.</p>
+
+<p>But on the film image taken weeks before there were two points of light.
+One was red, with Roger Hunter's claim number beneath it. The other was
+white, so close to the first that even at full magnification it was
+barely distinguishable.</p>
+
+<p><i>But it was there.</i></p>
+
+<p>Tom's hands were trembling with excitement; he nearly dropped the phone
+receiver as he punched the buttons to ring the apartment. Greg's face
+appeared on the screen, puffy with sleep. "What's that? Thought you were
+in bed...."</p>
+
+<p>"You've got to get down here," Tom said.</p>
+
+<p>Greg blinked, waking up. "What's the matter? Where are you?"</p>
+
+<p>"In the Map Room. Wake Johnny up and get down here. And try to get hold
+of the Major."</p>
+
+<p>"You've found something," Greg said, excited now.</p>
+
+<p>"I've found something," Tom said. "I've found where Dad hid his
+strike ... and I know how we can find it! We've got the answer, Greg."</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="c14_The_Missing_Asteroid" id="c14_The_Missing_Asteroid"></a>14. The Missing Asteroid</h2>
+
+
+<p>It had been a wild twelve hours since Tom Hunter's call to his brother
+from the Map Room in Sun Lake City. The Major had arrived first, still
+buttoning his shirt and wiping sleep from his eyes. Johnny and Greg came
+in on his heels. They had found Tom waiting for them, so excited he
+could hardly keep his words straight.</p>
+
+<p>He told them what he had found, and they wondered why they had not
+thought of it from the first moment. "We knew there had to be an
+answer," Tom said, "some place Dad could have used for a hiding place,
+some place nobody would even think to look. Dad must have realized that
+he didn't have much time. When he saw his chance, he took it."</p>
+
+<p>And it was pure, lucky chance. Tom showed them the section of the Map he
+had examined, with the pinpoint of light representing Roger Hunter's
+asteroid claim. Then the Map Control officer ... much more alert when he
+saw Major Briarton ... brought an armload of films up and loaded them
+into the projector. They stared at the screen, and saw the two pinpoints
+of light where one was now.</p>
+
+<p>"What was the date of this?" the Major asked sharply.</p>
+
+<p>"Two days before Dad died," Tom said. "There's quite a distance between
+them there ... but watch. One frame for every hour. Watch what happens."</p>
+
+<p>He began running the film, the record taken from the Map itself,
+accurate as clockwork. The white dot was moving in toward the red dot at
+a forty-degree angle. For an instant it looked as though the two were
+colliding ... and then the distance between them began to widen again.
+Slowly, hour by hour, the white dot was moving away, off the screen
+altogether....</p>
+
+<p>The Major looked up at Tom and slammed his fist on the chair-arm. "By
+the ten moons of Saturn...." he exploded, and then he was on his feet,
+shouting at the startled Map Control officer. "Get me Martinson down
+here, and fast. Call the port on a scrambled line and tell them to stand
+by with a ship on emergency call, with a crack interceptor pilot ready
+to go. Then get me the plotted orbits of every eccentric asteroid that's
+crossed Mars' orbit in the last two months. And double-A security on
+everything ... we don't want to let Tawney get wind of this...."</p>
+
+<p>Later, while they waited, they went over it to make sure that nothing
+was missing. "No wonder we couldn't spot it," the Major said. "We were
+looking for an asteroid in a standard orbit in the Belt."</p>
+
+<p>"But there wasn't any," Tom said. "Dad's rock was isolated, nowhere near
+any others. And we were so busy thinking of the thousands of rocks in
+normal orbits between Mars and Jupiter that we forgot that there are a
+few eccentric ones that just don't travel that way."</p>
+
+<p>"Like this one." The Major stared at the screen. "A long, intersecting
+orbit. It must swing out almost to Jupiter's orbit at one end, and come
+clear in to intersect Earth's orbit at the other end...."</p>
+
+<p>"Which means that it cuts right through the Asteroid Belt and on out
+again." Tom grinned. "Dad must have seen it coming ... must have thought
+it was on collision course for a while. But he also must have realized
+that if he could hide something on its surface as it came near, it would
+be carried clear out of the Belt altogether in a few days' time."</p>
+
+<p>"And if we can follow it up and intercept it...." The Major was on his
+feet, talking rapidly into the telephone. Sleep was forgotten now,
+nothing mattered but pinpointing a tiny bit of rock speeding through
+space. Within an hour the asteroid had been identified, its eccentric
+orbit plotted. The coordinates were taped into the computers of the
+waiting Patrol ship, as the preparations for launching were made.</p>
+
+<p>It could not be coincidence. Somewhere on the surface of that tiny
+planetoid racing in toward the Sun they knew they would find Roger
+Hunter's secret.</p>
+
+<hr style='width: 45%;' />
+
+<p>Below them, as they watched, the jagged surface of the asteroid drew
+closer.</p>
+
+<p>It was not round ... it was far too tiny a bit of cosmic debris to have
+sufficient gravity to crush down rocks and round off ragged corners. It
+was roughly oblong in shape, and one side was sheer smooth rock surface.
+The other side was rough, bristling with jutting rock. More than
+anything else it looked like a ragged mountain top, broken off at the
+peak and hurled into space by an all-powerful hand.</p>
+
+<p>Slowly the scout-ship moved closer, braking with its forward jets. The
+pilot was expert. Carefully and surely he aligned the ship with the rock
+in speed and direction. In the accelleration cot Tom could feel only an
+occasional gentle tug as the power cut on and off.</p>
+
+<p>Then the Lieutenant said, "I think we can make a landing now, Major."</p>
+
+<p>"Fine. Take a scooter down first, and carry a guy line."</p>
+
+<p>They unstrapped, and changed into pressure suits. In the airlock they
+waited until the Lieutenant had touched the scooter down. Then Major
+Briarton nodded, and they clamped their belts to the guy line.</p>
+
+<p>One by one they leaped down toward the rock.</p>
+
+<p>From a few miles out in space, the job of searching the surface had not
+appeared difficult. From the rock itself, things looked very different.
+There was no way, from the surface, to scan large areas, and the surface
+was so rough that they had to take constant care not to damage their
+boots or rip holes in their suits. There were hundreds of crevices and
+caves, half concealed by the loose rock that crumbled under their feet
+as they moved.</p>
+
+<p>They spread out from the scooter for an hour of fruitless searching. Tom
+spent most of the time pulling his boots free of surface cracks and
+picking his way over heaps of jagged rock. None of them got farther than
+a hundred yards from the starting place. None of them found anything
+remarkable.</p>
+
+<p>"We could spend weeks covering it this way," Greg said when they met at
+the scooter again. "Why don't I take the scooter and criss-cross the
+whole surface at about fifty feet? If I spot anything, I'll yell."</p>
+
+<p>It seemed like a good idea. Greg strapped himself into the scooter's
+saddle, straddling the fuel tanks, using the hand jet to guide himself
+as he lifted lightly off the surface. He disappeared over the horizon of
+rock, then reappeared as he moved over the surface and back.</p>
+
+<p>Tom and Johnny waited with the Major. Twenty minutes later Greg brought
+the tiny craft back again. "It's no good," he said. "I've scanned the
+whole bright-side, came as close as I dared."</p>
+
+<p>"No sign of anything?" Johnny said.</p>
+
+<p>"Not a thing. The dark side looks like a sheer slab, from what my lights
+show. If we only had some idea what we were looking for...."</p>
+
+<p>"Maybe you weren't close enough," Tom said. "Why not drop each of us off
+to take a quarter of the bright-side and work our way in?"</p>
+
+<p>The others agreed. Tom waited until the Major and Johnny had been
+posted; then he hopped on the scooter behind Greg and dropped off almost
+at the line of darkness, where the sheer slab began. All of them had
+hoped that there might be a sign, something that Roger Hunter might have
+left to mark his cache, but if there was one none of them spotted it.
+Tom checked with the others by the radio in his helmet, and started
+moving back toward the center of the bright side.</p>
+
+<p>An hour later he was only halfway to the center, and he was nearly
+exhausted. At a dozen different spots he thought he had found a
+promising cleft in the rock, a place where something might have been
+concealed ... but exploration of the clefts proved fruitless.</p>
+
+<p>And now his confidence began to fail. Supposing he had been wrong? They
+knew the rock had passed very close to Roger Hunter's asteroid, the
+astronomical records proved that. But suppose Dad had not used it as his
+hiding place at all? He pulled himself around another jagged rock shelf,
+staring down at the rough asteroid surface beyond....</p>
+
+<p>At the base of the rock shelf, something glinted in the sunlight. He
+leaped down, and thrust his hand into a small crevice in the rock. His
+hand closed on a small metal object.</p>
+
+<p>It was a gun. It felt well balanced, familiar in his hand ... the
+revolver Dad had always carried in his gun case.</p>
+
+<p>He had to let them know. He was just snapping the speaker switch when he
+heard a growl of static in his earphones, and then Greg's voice,
+high-pitched and excited. "Over here! I think I've found something!"</p>
+
+<p>It took ten minutes of scrambling over the treacherous surface to reach
+Greg. Tom saw his brother tugging at a huge chunk of granite that was
+wedged into a crevice in the rock. Tom got there just as the Major and
+Johnny topped a rise on the other side and hurried down to them.</p>
+
+<p>The rock gave way, rolling aside, and Greg reached down into the
+crevice. Tom leaned over to help him. Between them they lifted out the
+thing that had been wedged down beneath the boulder.</p>
+
+<p>It was a metal cylinder, four feet long, two feet wide, and bluntly
+tapered at either end. In the sunlight it gleamed like polished silver,
+but they could see a hairline break in the metal encircling the center
+portion.</p>
+
+<p>They had found Roger Hunter's bonanza.</p>
+
+<hr style='width: 45%;' />
+
+<p>In the cabin of the scout-ship they broke the cylinder open into two
+perfect halves. It came apart easily, a shell of paper-thin but
+remarkably strong metal, protecting the tightly packed contents.</p>
+
+<p>There was no question what the cylinder was, even though there was
+nothing inside that looked even slightly familiar at first examination.
+There were several hundred very tiny thin discs of metal that fit on the
+spindle of a small instrument that was packed with them. There were
+spools of film, thin as tissue but amazingly strong. Examined against
+the light in the cabin, the film seemed to carry no image at all ... but
+there was another small machine that accepted the loose end of the film,
+and a series of lenses that glowed brightly with no apparent source of
+power. There was a thick block of shiny metal covered on one side with
+almost invisible scratches....</p>
+
+<p>A time capsule, beyond doubt. A confusing treasure, at first glance, but
+the idea was perfectly clear. A hard shell of metal protecting the
+records collected inside....</p>
+
+<p><i>Against what? A planetary explosion? Some sort of cosmic disaster that
+had blown a planet and its people into the fragments that now filled the
+Asteroid Belt?</i></p>
+
+<p>At the bottom of the cylinder was a small tube of metal. They examined
+it carefully, trying to guess what it was supposed to be. At the bottom
+was a tiny stud. When they pressed it, the cylinder began to expand and
+unfold, layer upon layer of thin glistening metallic material that
+spread out into a sheet that stretched halfway across the cabin.</p>
+
+<p>They stared down at it. The metal seemed to have a life of its own,
+glowing and glinting, focussing light into pinpoints on its surface.</p>
+
+<p>It was a map.</p>
+
+<p>At one side, a glowing ball with a fiery corona, an unmistakeable
+symbol that any intelligent creature in the universe that was able to
+perceive it at all would recognize as a star. Around it, in clearly
+marked orbits, ten planets. The third planet had a single satellite, the
+fourth two tiny ones. The sixth eleven. The seventh planet had ten, and
+was encircled by glowing rings.</p>
+
+<p>But the fifth planet was broken into four parts.</p>
+
+<p>Beyond the tenth planet there was nothing across a vast expanse of the
+map ... but at the far side was another star symbol, this one a double
+star with four planetary bodies.</p>
+
+<p>They stared at the glowing map, speechless. There could be no mistaking
+the meaning of the thing that lay before them, marked in symbols that
+could mean only one thing to any intelligence that could recognize stars
+and planets.</p>
+
+<p>But in the center of the sheet was another symbol. It lay halfway
+between the two Solar Systems, in the depths of interstellar space. It
+was a tiny picture, a silvery sliver of light, but it too was
+unmistakeable.</p>
+
+<p>It could be nothing else but a Starship.</p>
+
+<hr style='width: 45%;' />
+
+<p>Later, as they talked, they saw that the map had told each of them,
+individually, the same thing. "They had a star-drive," Tom said.
+"Whatever kind of creatures they were, and whatever the disaster that
+threatened their planet, they had a star-drive to take them out of the
+Solar System to another star."</p>
+
+<p>"But why leave a record?" Greg wanted to know. "If nobody was here to
+use it...."</p>
+
+<p>"Maybe for the same reason that Earthmen bury time capsules with records
+of their civilization," Major Briarton said. "I'd guess that the records
+here will tell, when they have been studied and deciphered. Perhaps
+there was already some sign of intelligent life developing elsewhere in
+the Solar System. Perhaps they hoped that some of their own people would
+survive. But they had a star-drive, so some of them must have escaped.
+And with the record here...."</p>
+
+<p>"We may be able to follow them," Greg said.</p>
+
+<p>"If we can decipher the record," Johnny Coombs said. "But we don't have
+any clue to their language."</p>
+
+<p>"Did you have any trouble understanding what the map had to say?" the
+Major said quietly.</p>
+
+<p>"No...."</p>
+
+<p>"I don't think the rest will be much more difficult. They were
+intelligent creatures. The record will be understandable, all right." He
+started to fold the map back into a tube again. "Maybe Roger Hunter
+tried to use the film projector. We'll never know. But he must have
+realized that he had discovered the secret of a star-drive. He realized
+that the United Nations were the ones to explore it and use it, and he
+gave his life to keep it out of the hands of Tawney and his men...."</p>
+
+<p>"A pity," a cold voice said close behind them, "that he didn't succeed,
+after all."</p>
+
+<p>They whirled. In the hatchway to the after-cabin, Merrill Tawney was
+standing, with a smile on his lips and a Markheim stunner trained
+directly on Major Briarton's chest.</p>
+
+
+
+<hr style="width: 65%;" />
+<h2><a name="c15_The_Final_Move" id="c15_The_Final_Move"></a>15. The Final Move</h2>
+
+
+<p>"I realize I'm much earlier than you expected, Major. You did a very
+neat job of camouflaging your takeoff ... we were almost fooled ... and
+no doubt the dummy ship you sent off later got full fanfare. I suppose
+there will be a dozen Patrol ships converging on this spot in a few
+hours, expecting to surprise a Jupiter Equilateral ship making a
+desperate attempt to hijack your little treasure here."</p>
+
+<p>The little fat man laughed cheerfully. "Unfortunately for you," he
+added, "we have many friends on Mars ... including a man in the Map
+room ... and I'm afraid your little trap isn't going to work after all."</p>
+
+<p>The Major's face was gray. "How did you get here?"</p>
+
+<p>"By hitch-hiking. How else? Most uncomfortable, back there, even with a
+pile of pressure suits for padding, but your pilot was really very
+skillful."</p>
+
+<p>Johnny Coombs turned on the Major. "What does he mean, a trap? I don't
+get this...."</p>
+
+<p>The Major sighed wearily. "I had to try to force his hand. Even if we
+found what we were looking for, we had no case that could stand up
+against them. We needed <i>proof</i> ... and I thought that with this as bait
+we could trap them. He's right about the Patrol ships ... but they won't
+be near for hours."</p>
+
+<p>"And that will be a little late to help," Tawney said pleasantly.</p>
+
+<p>The Major glared at him. "Maybe so ... but you've gone too far this
+time. This is an official U.N. ship. You'll never be able to go back to
+Mars."</p>
+
+<p>"Really?" the fat man said. "And why not? Officially I'm on Mars right
+now, with plenty of people to swear to the fact." He chuckled. "You seem
+to forget that little matter of proof, Major. When your Patrol ships
+find a gutted ship and five corpses, they may suspect that something
+more than an accident was involved, but what can they prove? Nothing
+more than they could prove in the case of Roger Hunter's accident.
+Scout-ships have been known to explode before."</p>
+
+<p>He ran his hand over the metal cylinder. "And as for this ... it's
+really a surprise. Of course when we failed to find any evidence of
+mining activity, we were certain that Roger Hunter's bonanza was
+something more than a vein of ore, but <i>this</i>! You can be certain that
+we will exploit the secret of a star-drive to the very fullest."</p>
+
+<p>"How do you think you can get away with it?" the Major said. "Turning up
+with something like that right after a whole series of suspicious
+accidents in space?"</p>
+
+<p>"Oh, we aren't as impatient as some people. We wouldn't be so foolish as
+to break the news now. Five years from now, maybe ten years, one of our
+orbit-ships will happen upon a silvery capsule on one of our asteroid
+claims, that's all. I wouldn't be surprised if a non-company observer
+might be on board at the time, maybe even a visiting Senator from Earth.
+For something this big, we can afford to be patient."</p>
+
+<p>There was silence in the little scout-ship cabin. The end seemed
+inevitable. This was a desperate move on Tawney's part. He was gambling
+everything on it; he would not take the chance of letting any of them
+return to Mars or anywhere else to testify.</p>
+
+<p>Greg caught Tom's eye, saw the hopelessness on his brother's face. He
+clenched his fists angrily at his side. If it were not for Tom, Dad's
+bonanza might have gone on circling the sun for centuries, maybe
+forever, wedged in its hiding place on the rocky surface of the
+eccentric asteroid.</p>
+
+<p>But it had been found. Earth needed a star-drive badly; a few more
+years, and the need would be desperate. And if a group of power-hungry
+men could control a star-drive and hold it for profit, they could
+blackmail an entire planet for centuries, and build an empire in space
+that could never be broken.</p>
+
+<p>He knew that it must not happen that way. Dad had died to prevent it.
+Now it was up to them.</p>
+
+<hr style='width: 45%;' />
+
+<p>Greg glanced quickly around the cabin, searching for some way out,
+something that might give them a chance. His eyes stopped on the control
+panel, and he sucked in his breath, his heart pounding. A
+possibility....</p>
+
+<p>It would require a swift, sure move, and someone to help, someone with
+fast reflexes. It was dangerous; they might all be killed. But if his
+training at Star-jump was good for anything, it might work.</p>
+
+<p>He caught Johnny Coombs' eye, winked cautiously. A frown creased
+Johnny's forehead. He shot a quick look at Tawney, then lowered his
+eyelid a fraction of an inch. Greg could see the muscles of his
+shoulders tightening.</p>
+
+<p>Greg took quick stock of the cabin again. Then he took a deep breath and
+bellowed, "Johnny ... <i>duck</i>!"</p>
+
+<p>Almost by reflex, Johnny Coombs hurled himself to the floor. Tawney
+swung the gun around. There was an ugly ripping sound as the stunner
+fired ... but Greg was moving by then. In two bounds he was at the
+control panel. He hooked an arm around a shock bar, and slammed the
+drive switch on full.</p>
+
+<p>There was a roar from below as the engines fired. Greg felt a jolt of
+pain as the accelleration jerked at his arm. Tom and the Major were
+slammed back against a bulkhead, then fell in a heap on top of Johnny
+and the Lieutenant as the awful force of the accelleration dragged them
+back. Across the cabin Tawney sprawled on the floor. The stunner flew
+from his hand and crashed against the rear bulkhead.</p>
+
+<p>On the panel Greg could see the accelleration gauge climbing
+swiftly ... past four g's, up to five, to six. The ship was moving
+wildly; there was no pilot, no course.</p>
+
+<p>With all the strength he could muster Greg tightened his arm on the
+shock bar, lifting his other arm slowly toward the cut-off switch. He
+had spent many hours in the accelleration centrifuge at Star-Jump,
+learning to withstand and handle the enormous forces of accelleration
+for brief periods, but the needle was still climbing and he knew he
+could not hold on long. His fingers touched the control panel. He
+strained, inching them up toward the switch....</p>
+
+<p>His fingers closed on the stud, and he pulled. The engine roar ceased.
+On the floor behind him Tawney moved sluggishly, trying to sit up. Blood
+was dripping from his nose. He was still too stunned to know what had
+happened.</p>
+
+<p>Greg leaped across the room, caught up the stunner, and then sank to the
+floor panting. "All right," he said as his breath came back, "that's
+all. Your ship may have trouble finding us now ... but I bet our pilot
+can get us back to Mars."</p>
+
+<hr style='width: 45%;' />
+
+<p>When they left the Sun Lake City infirmary it was almost noon, and the
+red sun was gleaming down from overhead. Walking slowly, the Hunter
+twins moved along the surface street toward the U.N. building.</p>
+
+<p>"He'll recover without any trouble," the doctor had assured them. "He
+caught the stunner beam in the shoulder, and it will be a while before
+he can use it, but Johnny Coombs will be hard to keep down."</p>
+
+<p>They had promised Johnny to return later. They had had check-ups
+themselves. Both Tom's eyes were surrounded by purple splotches, and his
+broken left arm was in a sling. Greg's arms and legs were so stiff he
+could hardly move them. The Major and the Lieutenant had been sore but
+uninjured.</p>
+
+<p>Now the boys walked without talking. Already a U.N. linguist was at work
+on the record tapes from the metal cylinder, and a mathematician was
+doing a preliminary survey on the math symbols on the metal block.</p>
+
+<p>"I hope there's no trouble reading them," Greg said.</p>
+
+<p>"There won't be. It'll take time, but the records are decipherable. And
+Dr. Raymond was certain that the engineering can be figured out. Earth
+is going to get her star-ship, all right."</p>
+
+<p>"And we've got work to do."</p>
+
+<p>"You mean the trial? I guess. The Major says that Jupiter Equilateral is
+trying to pin the whole thing on Tawney now. They won't get away with
+it, but it may be nasty just the same."</p>
+
+<p>"Well, one thing's sure ... there'll be some changes made, with the U.N.
+moving out into the Belt," Greg said.</p>
+
+<p>Somewhere in the distance the twins heard the rumble of engines. They
+stopped and watched as a great silvery cargo ship lifted from the space
+port and headed up into the dark blue sky. They watched it until it
+disappeared from sight.</p>
+
+<p>They were both thinking the same thing.</p>
+
+<p>An Earth-bound ship, powerful and beautiful, but limited now to the sun
+and nine planets, unable to reach farther out.</p>
+
+<p>But someday soon a different kind of ship would rise.</p>

+
+1.F.
+
+1.F.1. Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection. Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.

+fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
+LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
+PROVIDED IN PARAGRAPH F3. YOU AGREE THAT THE FOUNDATION, THE

+
+1.F.4. Except for the limited right of replacement or refund set forth
+in paragraph 1.F.3, this work is provided to you 'AS-IS' WITH NO OTHER

+
+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, is critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at https://www.pglaf.org.
+
+
+Section 3. Information about the Project Gutenberg Literary Archive
+Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Its 501(c)(3) letter is posted at
+https://pglaf.org/fundraising. Contributions to the Project Gutenberg
+Literary Archive Foundation are tax deductible to the full extent
+permitted by U.S. federal laws and your state's laws.
+

+Fairbanks, AK, 99712., but its volunteers and employees are scattered
+throughout numerous locations. Its business office is located at
+809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887, email
+business@pglaf.org. Email contact links and up to date contact

+page at https://pglaf.org
+
+For additional contact information:
+ Dr. Gregory B. Newby
+ Chief Executive and Director
+ gbnewby@pglaf.org
+
+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit https://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including including checks, online payments and credit card
+donations. To donate, please visit: https://pglaf.org/donate
+
+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart was the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ https://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.

+
+
+1. Trouble Times Two
+
+
+The sun was glowing dull red as it slipped down behind the curving
+horizon of Mars, but Gregory Hunter was not able to see it.
+
+There was no viewscreen in the ship's cabin; it was too tiny for that.
+Greg twisted around in the cockpit that had been built just big enough
+to hold him, and shifted his long legs against the brace-webbing, trying
+to get them comfortable.
+
+He knew he was afraid ... but nobody else knew that, not even the
+captain waiting at the control board on the satellite, and in spite of
+the fear Greg Hunter would not have traded places at this moment with
+anyone else in the universe.
+
+He had worked too hard and waited too long for this moment.
+
+He heard the count-down monitor clicking in his ears, and his hands
+clenched into fists. How far from Mars would he be ten minutes from now?
+He didn't know. Farther than any man had ever traveled before in the
+space of ten minutes, he knew, and faster. How far and how fast would
+depend on him alone.
+
+"All set, Greg?" It was the captain's voice in the earphones.
+
+"All set, Captain."
+
+"You understand the program?"
+
+Greg nodded. "Twenty-four hours out, twenty-four hours back, ninety
+degrees to the ecliptic, and all the accelleration I can stand both
+ways."
+
+Greg grinned to himself. He thought of the months of conditioning he had
+gone through to prepare for this run ... the hours in the centrifuge to
+build up his tolerance to accelleration, the careful diet, the rigorous
+hours of physical conditioning. It was only one experiment, one tiny
+step in the work that could someday give men the stars, but to Gregory
+Hunter at this moment it was everything.
+
+"Good luck, then." The captain cut off, and the blastoff buzzer sounded.
+
+He was off. His heart hammered in his throat, and his eyes ached
+fiercely, but he paid no attention. His finger crept to the air-speed
+indicator, then to the cut-off switch. When the pressure became too
+great, when he began to black out, he would press it.
+
+But not yet. It was speed they wanted; they had to know how much
+accelleration a man could take for how long and still survive, and now
+it was up to him to show them.
+
+Fleetingly, he thought of Tom ... poor old stick-in-the-mud Tom, working
+away in his grubby little Mars-bound laboratory, watching bacteria grow.
+Tom could never have qualified for a job like this. Tom couldn't even go
+into free-fall for ten minutes without getting sick all over the place.
+Greg felt a surge of pity for his brother, and then a twinge of
+malicious anticipation. Wait until Tom heard the reports on _this_ run!
+It was all right to spend your time poking around with bottles and test
+tubes if you couldn't do anything else, but it took something special to
+pilot an XP ship for Project Star-Jump. And after this run was over,
+even Tom would have to admit it....
+
+There was a lurch, and quite suddenly the enormous pressure was gone.
+
+Something was wrong. He hadn't pushed the cut-off button, yet the ship's
+engines were suddenly silent. He jabbed at the power switch. Nothing
+happened. Then the side-jets sputted, and he was slammed sideways into
+the cot.
+
+He snapped on the radio speaker. "Control ... can you hear me?
+Something's gone wrong out here...."
+
+"Nothing's wrong," the captain's voice said in his earphones. "Just sit
+tight. I'm bringing you back in. There's a call here from Sun Lake City.
+They want you down there in a hurry. We'll have to scratch you on this
+run."
+
+"_Who_ wants me down there?"
+
+"The U.N. Council office. Signed by Major Briarton himself and I can't
+argue with the Major. We're bringing you in."
+
+Greg Hunter sank back, disappointment so thick he could taste it in his
+mouth. Sun Lake City! That meant two days at least, one down, one back,
+maybe more if connections weren't right. It meant that the captain would
+send Morton or one of the others out in his place. It meant....
+
+Suddenly he thought of what else it meant, and a chill ran up his back.
+
+There was only one reason Major Briarton would call him in like this.
+Something had happened to Dad.
+
+Greg leaned back in the cot, suddenly tense, as a thousand frightful
+possibilities flooded his mind. It could only mean that Dad was in some
+kind of trouble.
+
+And if anything had happened to Dad....
+
+ * * * * *
+
+The sun was sinking rapidly toward the horizon when the city finally
+came into sight in the distance, but try as he would, Tom Hunter could
+not urge more than thirty-five miles an hour from the huge lurching
+vehicle he was driving.
+
+On an open paved highway the big pillow-wheeled Sloppy Joe would do
+sixty in a breeze, but this desert route was far from a paved road.
+Inside the pressurized passenger cab, Tom gripped the shock-bars with
+one arm and the other leg, and jammed the accelerator to the floor. The
+engine coughed, but thirty-five was all it would do.
+
+Through the windshield Tom could see the endless rolling dunes of the
+Martian desert stretching to the horizon on every side. They called Mars
+the Red Planet, but it was not red when you were close to it. There were
+multitudes of colors here ... yellow, orange, brown, gray, occasional
+patches of gray-green ... all shifting and changing in the fading
+sunlight. Off to the right were the worn-down peaks of the Mesabi II,
+one of the long, low mountain ranges of almost pure iron ore that helped
+give the planet its dull red appearance from outer space. And behind
+him, near the horizon, the tiny sun glowed orange out of a blue-black
+sky.
+
+Tom fought the wheel as the Sloppy Joe jounced across a dry creek bed,
+and swore softly to himself. Why hadn't he kept his head and waited for
+the mail ship that had been due at the Lab to give him a lift back? He'd
+have been in Sun Lake City an hour ago ... but the urgency of the
+message had driven caution from his mind.
+
+A summons from the Mars Coordinator of the U.N. Interplanetary Council
+was the same as an order ... but there was more to Tom's haste than
+that. There was only one reason that Major Briarton would be calling him
+in to Sun Lake City, and that reason meant trouble.
+
+Something was wrong. Something had happened to Dad.
+
+Now Tom peered up at the dark sky, squinting into the sun. Somewhere out
+there between Mars and Jupiter was a no-man's-land of danger, a great
+circling ring of space dirt and debris, the Asteroid belt. And somewhere
+out there, Dad was working.
+
+Tom thought for a moment of the pitiful little mining rig that Roger
+Hunter had taken out to the Belt ... the tiny orbit-ship to be used for
+headquarters and storage of the ore; the even tinier scout ship, Pete
+Racely's old _Scavenger_ that he had sold to Roger Hunter for back taxes
+and repairs when he went broke in the Belt looking for his Big Strike.
+It wasn't much of a mining rig for anybody to use, and the dangers of a
+small mining operation in the Asteroid Belt were frightening. It took
+skill to bring a little scout-ship in for a landing on an asteroid rock
+hardly bigger than the ship itself; it took even more skill to rig the
+controlled-Murexide charges to blast the rock into tiny fragments, and
+then run out the shiny magnetic net to catch the explosion debris and
+bring it in to the hold of the orbit-ship....
+
+Tom Hunter scowled, trying to shake off the feeling of uneasiness that
+was nibbling at his mind. Asteroid mining was dangerous ... but Dad was
+no novice. Nobody on Mars knew how to handle a mining rig better than
+Roger Hunter did. He knew what he was doing out there, there was no real
+danger for him or was there....
+
+Roger Hunter, a good man, a gentle and peaceful man, had finally seen
+all he could stomach of Jupiter Equilateral and its company mining
+policies six months before. He had told them so in plain, simple
+language when he turned in his resignation. They didn't try to stop
+him ... a man was still free to quit a job on Mars if he wanted to, even
+a job with Jupiter Equilateral. But it was an open secret that the big
+mining outfit had not liked Roger Hunter's way of resigning, taking half
+a dozen of their first-rate mining engineers with him. There had been
+veiled threats, rumors of attempts to close the markets to Roger
+Hunter's ore, in open violation of U.N. Council policies on Mars....
+
+Tom fought the wheel as the big tractor lumbered up another rise, and
+the huge plastic bubble of Sun Lake City came into view far down the
+valley below.
+
+He thought of Greg. Had Greg been summoned too? He closed his lips
+tightly as a wave of anger passed through his mind. If anything had
+happened, no matter what, he thought, Greg would be there. Taking over
+and running things, as usual. He thought of the last time he had seen
+his brother, and then deliberately blocked out the engulfing bitterness.
+
+That had been more than a year ago. Maybe Greg had changed since then.
+
+But somehow, Tom didn't think so.
+
+The Sloppy Joe was on the valley floor now, and ahead the bubble
+covering the city was drawing closer. The sun was almost gone; lights
+were appearing inside the plastic shielding. Born and raised on Mars,
+Tom had seen the teeming cities of Earth only once in his life ... but
+to him none of the splendors of the Earth cities could match the simple,
+quiet beauty of this Martian outpost settlement. There had been a time
+when people had said that Sun Lake City could never be built, that it
+could never survive if it were, but with each successive year it grew
+larger and stronger, the headquarters city for the planet that had
+become the new frontier of Earth.
+
+The radiophone buzzed, and the airlock guard hailed him when he returned
+the signal. Tom gave his routine ID. He guided the tractor into the
+lock, waited until pressure and atmosphere rose to normal, and then
+leaped out of the cab.
+
+Five minutes later he was walking across the lobby of the Interplanetary
+Council building, stepping into the down elevator. Three flights below
+he stepped out into the office corridor of the U.N. Interplanetary
+Council on Mars.
+
+If there was trouble, this was where he would find it.
+
+He paused for a minute before the gray plastic door marked MAJOR FRANK
+BRIARTON in raised stainless steel letters. Then he pushed open the door
+and walked into the ante-room.
+
+It was empty. Suddenly he felt a touch on his shoulder. Behind him, a
+familiar voice said, "Hello, Twin."
+
+ * * * * *
+
+At first glance they looked like carbon copies of each other, although
+they were no more identical than identical twins ever are. Greg stood a
+good two inches taller than Tom. His shoulders were broad, and there was
+a small gray scar over one eye that stood out in contrast to the healthy
+tanned color of his face. Tom was of slighter build, and wirier, his
+skin much more pale.
+
+But they had the same dark hair, the same gray eyes, the same square,
+stubborn line to the jaw. They looked at each other for a moment without
+speaking. Then Greg grinned and clapped his brother on the shoulder.
+
+"So you got here, finally," he said. "I was beginning to think I'd have
+to go out on the desert and find you."
+
+"Oh, I got here, all right," Tom said. "I see you did too."
+
+"Yes," Greg said heavily. "Can't argue with the major, you know."
+
+"But what does he want?"
+
+"How should I know? All he said was to get down here fast. And now he
+isn't even here himself."
+
+"Is Dad on Mars?" Tom asked.
+
+Greg looked at him. "I don't know."
+
+"We could check the register."
+
+"I already checked it. He has not logged in, but that doesn't mean
+anything."
+
+"I suppose not," Tom said glumly.
+
+They were silent for a moment. Then Greg said, "Look, what are you
+worried about? Nothing could have happened to Dad. He's been mining the
+Belt for years."
+
+"I know. I just wish he were here, that's all. If he's in some kind of
+trouble...."
+
+"What kind of trouble? You're looking for spooks."
+
+"Spooks like Jupiter Equilateral, maybe," Tom said. "They could make
+plenty of trouble for Dad."
+
+"With the U.N. in the driver's seat here? They wouldn't dare. Why do you
+think the major rides them so hard with all the claim-filing
+regulations? He'd give his right arm for a chance to break that outfit
+into pieces."
+
+"I still wish somebody had gone out to the Belt with Dad," Tom said.
+
+Just then the door opened. The newcomer was a tall, gray-haired man with
+U.N. Council stripes on his lapel, and major's rockets on his shoulders.
+"Sorry I'm late, boys," Major Briarton said. "I'd hoped to be here when
+you arrived. I'm sorry to pull you in here like this, but I'm afraid I
+had no choice. When did you boys hear from your father last?"
+
+They looked at each other. "I saw him six weeks ago," Tom said. "Just
+before he left to go out to the Belt again."
+
+"Nothing since then?"
+
+"Not a word."
+
+The major chewed his lip. "Greg?"
+
+"I had a note at Christmas, I think. But what...."
+
+"What did he say in the note?"
+
+"He said Merry Christmas and Happy New Year. Dad isn't much of a letter
+writer."
+
+"Nothing at all about what he was doing?"
+
+Greg shook his head. "Look, Major, if there's some sort of trouble...."
+
+"Yes, I'm afraid there's trouble," the major said. He looked up at them,
+and spread his hands helplessly. "There isn't any easy way to tell you,
+but you've got to know. There's been an accident, out in the Belt."
+
+"Accident?" Greg said.
+
+"A very serious accident. A fuel tank exploded in the scooter your
+father was riding back to the _Scavenger_. It must have been very
+sudden, and by the time help arrived...." The major broke off, unable to
+find words.
+
+For a long moment there was utter silence in the room. Outside, an
+elevator was buzzing, and a typewriter clicked monotonously somewhere in
+the building.
+
+Then Tom Hunter broke the silence. "Who was it, Major?" he said. "Who
+killed Dad? Tell us, or we'll find out!"
+
+
+
+
+2. Jupiter Equilateral
+
+
+For a moment, Major Briarton just stared at him. Then he was on his
+feet, shaking his head as he came around the desk. "Tom, use your head,"
+he said. "It's as much of a shock to me as it is to you, but you can't
+afford to jump to false conclusions...."
+
+Tom Hunter looked up bitterly. "He's dead, isn't he?"
+
+"Yes, he's dead. He must have died the instant of the explosion...."
+
+"You mean you don't know?"
+
+"I wasn't there at the time it happened, no."
+
+"Then who was?"
+
+ * * * * *
+
+Major Briarton spread his hands helplessly. "Nobody was. Your father was
+alone. From what we could tell later, he'd left the _Scavenger_ to land
+on one of his claims, using the ship's scooter for the landing. He was
+on the way back to the _Scavenger_ when the rear tank exploded. There
+wasn't enough left of it to tell what went wrong ... but it was an
+accident, there was no evidence to suggest anything else."
+
+Tom looked at him. "You really believe that?"
+
+"I can only tell you what we found."
+
+"Well, I don't believe it for a minute," Tom said angrily. "How long
+have you and Dad been friends? Twenty years? Twenty-five? Do you really
+think Dad would have an accident with a mining rig?"
+
+"I know he was an expert engineer," the major said. "But things can
+happen that even an expert can't foresee, mining in the Belt."
+
+"Things like a fuel tank exploding? Not to Dad, they would never happen.
+I don't care what anybody says...."
+
+"Easy, Tom," Greg said.
+
+"Well, I won't take it easy. Dad was too careful for something like that
+to happen. If he had an accident, somebody _made_ it happen."
+
+Greg turned to the major. "What was Dad doing out there?"
+
+"Mining."
+
+"By himself? No crew at all?"
+
+"No, he was alone."
+
+"I thought the regulations said there always had to be at least two men
+working an asteroid claim."
+
+"That's right. Your father had Johnny Coombs with him when he left Sun
+Lake City. They signed out as a team ... and then Johnny came back to
+Mars on the first shuttle ship."
+
+"How come?"
+
+"Not even Johnny knows. Your father just sent him back, and there was
+nothing we could do about it then. The U.N. has no jurisdiction in the
+belt, unless a major crime has been committed." Major Briarton shook his
+head helplessly. "If a man is determined to mine a claim all by himself
+out there, he can find a dozen different ways to wiggle out of the
+regulations."
+
+"But Dad would never be that stupid," Greg said. "If he was alone when
+it happened, who found him?"
+
+"A routine U.N. Patrol ship. When Roger failed to check in at the
+regular eight-hour signal, they went out to see what was wrong. But by
+the time they reached him, it was too late to help."
+
+"I just don't get it," Greg said. "Dad had more sense than to try to
+mine out there all by himself."
+
+"I know," the major said. "I don't know the answer. I had the Patrol
+ship go over the scene of the accident with a comb after they found what
+had happened, but there was nothing there to find. It was an accident,
+and that's that."
+
+"What about Jupiter Equilateral?" Tom said hotly. "Everybody knows they
+were out to get Dad ... why don't you find out what _they_ were doing
+when it happened, bring them in for questioning...."
+
+"I can't do that, I haven't a scrap of evidence," the major said
+wearily.
+
+"Why can't you? You're the Mars Coordinator, aren't you? You act like
+you're scared of them."
+
+Major Briarton's lips tightened angrily. "All right, since you put it
+that way ... I _am_ scared of them. They're big, and they're powerful.
+If they had their way, there wouldn't be any United Nations control on
+Mars, there wouldn't be _anybody_ to fight them and keep them in check.
+There wouldn't be any independent miners out in the Belt, either,
+because they'd all be bought out or dead, and Earth would pay through
+the nose for every ounce of metal that they got from the Asteroid Belt.
+That company has been trying to drive the U.N. off Mars for thirty
+years, and they've come so close to it that it scares me plenty." He
+pushed his chair back sharply and rose to his feet. "And that is
+exactly why I refuse to stir up a mess over this thing, unhappy as
+it is, without something more than suspicions and rumors to back me
+up ... because all Jupiter Equilateral needs is one big issue to make us
+look like fools out here, and we're through."
+
+He crossed the room to a wall cabinet, opened it, and pulled out a
+scarred aluminum box. "We found this in the cabin of the _Scavenger_. I
+thought you boys might want it."
+
+They both recognized it instantly ... the battered old spacer's pack
+that Roger Hunter had used for as long as they could remember. It seemed
+to them, suddenly, as if a part of him had appeared here in the room
+with them. Greg looked at the box and turned away. "You open it," he
+said to Tom in a sick voice.
+
+There was nothing much inside ... some clothing, a pipe and tobacco
+pouch, a jack knife, half a dozen other items so familiar that Tom could
+hardly bear to touch them. At the bottom of the pack was the heavy
+leather gun case which had always held Roger Hunter's ancient .44
+revolver. Tom dropped it back without even opening the flap. He closed
+the box and took a deep breath. "Then you really believe that it was an
+accident and nothing more?" he said to the major.
+
+Major Briarton shook his head. "What I think or don't think doesn't make
+any difference. It just doesn't matter. In order to do anything, I've
+got to have evidence, and there just isn't any evidence. I can't even
+take a ship out there for a second look, with the evidence I have, and
+that's all there is to it."
+
+"But you think that maybe it wasn't an accident, just the same," Tom
+pursued.
+
+The major hesitated. Then he shook his head again. "I'm sorry, but I've
+got to stand on what I've said. And I think you'd better stand on it,
+too. There's nothing else to be done."
+
+ * * * * *
+
+It should have been enough, but it wasn't. As Tom Hunter walked with his
+brother down the broad Upper Ramp to the business section of Sun Lake
+City, he could not shake off the feeling of helpless anger, the growing
+conviction that Roger Hunter's death involved something more than the
+tragic accident in space that Major Briarton had insisted it was.
+
+"He didn't tell us everything he knew," Tom said fiercely. "He didn't
+say everything he wanted to say, either. He doesn't think it was an
+accident any more than I do."
+
+"How do you know, are you a mind reader?"
+
+"No."
+
+"Well, Dad wasn't a superman, either. He was taking an awful risk,
+trying to work a mining rig by himself, and he had a bad break. Why do
+you have to have somebody to blame for it?"
+
+"Keep talking," Tom said. "You'll convince yourself yet."
+
+Greg just jammed his hands in his pockets, and they walked in silence
+for a moment.
+
+For Tom and Greg Hunter, Sun Lake City had always been home. Now they
+walked along the Main Concourse, Tom with the aluminum box under his
+arm, Greg with his own spacer's pack thrown over his shoulder. They
+didn't talk; rather than being drawn closer by the news of the tragedy,
+it seemed that they had drawn farther apart, as though the one common
+link that had held them together had suddenly been broken.
+
+Finally Tom broke the silence. "At least there's one thing we can do,"
+he said. "I'm going to call Johnny Coombs."
+
+He shortly found a phone booth and dialed a number. Johnny had been a
+friend of the family for years; he and Roger Hunter had been partners in
+many mining ventures in the Asteroid Belt before Roger had taken his
+position with Jupiter Equilateral. If Johnny had any suspicions that
+Roger Hunter's accident had been more than an accident, he certainly
+would not hesitate to voice them....
+
+After a dozen rings, Tom hung up, tried another number. There was no
+answer there, either. Frowning, Tom rang the city's central paging
+system. "Put in a personal call for Johnny Coombs," he said when the
+"record" signal flashed on. "Tell him to contact the Hunters when he
+comes in. We'll be at home...."
+
+They resumed their silent walk. When they reached H wing on the fourth
+level, they turned right down an apartment corridor, and stopped in
+front of a familiar doorway. Tom pressed his palm against the
+lock-plate, and the door swung open.
+
+It was home to them, the only home they had ever known. Soft lights
+sprang up on the walls of the apartment as the door opened. Tom saw the
+old bookcases lining the walls, the drafting-board and light at the far
+end of the room, the simple chairs and dining table, the door which led
+into the bedroom and kitchen beyond. The room had the slightly
+disheveled look that it had had ever since Mom had died ... a slipper on
+the floor here, a book face down on the couch there....
+
+It looked as though Dad had just stepped out for an hour or so.
+
+Tom was three steps into the room before he saw the visitor.
+
+The man was sitting comfortably in Roger Hunter's easy chair, a short,
+fat man with round pink cheeks that sagged a little and a double chin
+that rested on his neck scarf. There were two other men in the room,
+both large and broad-shouldered; one of them nodded to the fat man, and
+moved to stand between the boys and the door.
+
+The fat man was out of his seat before the boys could speak, smiling at
+them and holding out his hand. "I wanted to be sure to see you before
+you left the city," he was saying, "so we just came on in to wait. I
+hope you don't mind our ... butting in, so to speak." He chuckled,
+looking from one twin to the other. "You don't know me, I suppose. I'm
+Merrill Tawney. Representing Jupiter Equilateral, you know."
+
+Tom took the card he was holding out, looked at the name and the tiny
+gold symbol in the corner, a letter "J" in the center of a triangle. He
+handed the card to Greg. "I've seen you before," he told the fat man.
+"What do you want with us?"
+
+Tawney smiled again, spreading his hands. "We've heard about the
+tragedy, of course. A shocking thing ... Roger was one of our group so
+recently. We wanted you to know that if there is anything at all we can
+do to help, we'd be only too glad...."
+
+"Thanks," Greg said. "But we're doing just fine."
+
+Tawney's smile tightened a little, but he hung onto it. "I always felt
+close to your father," he said. "All of us at Jupiter Equilateral did.
+We were all sorry to see him leave."
+
+"I bet you were," Greg said, "he was the best mining engineer you ever
+had. But Dad could never stand liars, or crooked ways of doing
+business."
+
+One of the men started for Greg, but the fat man stopped him with a wave
+of his hand. "We had our differences of opinion," he said. "We saw
+things one way, your father saw them another way. But he was a fine man,
+one of the finest...."
+
+"Look, Mr. Tawney, you'd better say what you came to say and get out of
+here," Greg said dangerously, "before we give your friends here
+something to do."
+
+"I merely came to offer you some help," Tawney said. He was no longer
+smiling. "Since your father's death, you two have acquired certain
+responsibilities. I thought we might relieve you of some of them."
+
+"What sort of responsibilities?"
+
+"You have an unmanned orbit-ship which is now a derelict in the Asteroid
+Belt. You have a scout-ship out there also. You can't just leave them
+there as a navigation hazard to every ship traveling in the sector.
+There are also a few mining claims which aren't going to be of much
+value to you now."
+
+"I see," Greg said. "Are you offering to buy Dad's mining rig?"
+
+"Well, I doubt very much that we'd have any use for it, as such. But we
+could save you the trouble of going out there to haul it in."
+
+"That's very thoughtful," Greg said. "How much are you offering?"
+
+Tom looked up in alarm. "Wait a minute," he said. "That rig's not for
+sale...."
+
+"How much?" Greg repeated.
+
+"Forty thousand dollars," Merrill Tawney said. "Ship, rig and claims.
+We'll even pay the transfer tax."
+
+Tom stared at the man, wondering if he had heard right. He knew what
+Roger Hunter had paid for the rig; he had been with Dad when the papers
+were signed. Tawney's offer was three times as much as the rig was
+worth.
+
+But Greg was shaking his head. "I don't think we could sell at that
+price."
+
+The fat man's hands fluttered. "You understand that those ships are
+hardly suited to a major mining operation like ours," he said, "and the
+claims...." He dismissed them with a wave of his hand. "Still, we'd want
+you to be happy with the price. Say, forty-five thousand?"
+
+Greg hesitated, shook his head again. "I guess we'd better think it
+over, Mr. Tawney."
+
+"Fifty thousand is absolutely the top," Tawney said sharply. "I have the
+papers right here, drawn up for your signatures, but I'm afraid we can't
+hold the offer open."
+
+"I don't know, we might want to do some mining ourselves," Greg said.
+"For all we know, Dad might have struck some rich ore on one of those
+claims."
+
+Tawney laughed. "I hardly think so. Those claims were all Jupiter
+Equilateral rejects. Our own engineers found nothing but low grade ore
+on any of them."
+
+"Still, it might be fun to look."
+
+"It could be very expensive fun. Asteroid mining is a dangerous
+business, even for experts. For amateurs...." Tawney spread his hands.
+"Accidents occur...."
+
+"Yes, we've heard about those accidents," Greg said coldly. "I don't
+think we're quite ready to sell, Mr. Tawney. We may never be ready to
+sell to you, so don't stop breathing until we call you. Now if there's
+nothing else, why don't you take your friends and go somewhere else?"
+
+The fat man scowled; he started to say something more, then saw the look
+on Greg's face, and shrugged. "I'd advise you to give it some careful
+thought," he said as he started for the door. "It might be very foolish
+for you to try to use that rig."
+
+Smiling, Greg closed the door in his face. Then he turned and winked at
+Tom. "Great fellow, Mr. Tawney. He almost had me sold."
+
+"So I noticed," Tom said. "For a while I thought you were serious."
+
+"Well, we found out how high they'd go. That's a very generous outfit
+Mr. Tawney works for."
+
+"Or else a very crooked one," Tom said. "Are you wondering the same
+thing I'm wondering?"
+
+"Yes," Greg said slowly. "I think I am."
+
+"Then that makes three of us," a heavy voice rumbled from the bedroom
+door.
+
+ * * * * *
+
+Johnny Coombs was a tall man, so thin he was almost gangling, with a
+long nose and shaggy eyebrows jutting out over his eyes. With his rudely
+cropped hair and his huge hands, he looked like a caricature of a
+frontier Mars-farmer, but the blue eyes under the eyebrows were not
+dull.
+
+"Johnny!" Tom cried. "We were trying to find you."
+
+"I know," Johnny said. "So have a lot of other people, includin' your
+friends there."
+
+"Well, did you hear what Tawney wanted?"
+
+"I'm not so quick on my feet any more," Johnny Coombs said, "but I got
+nothin' wrong with my ears." He scratched his jaw and looked up sharply
+at Greg. "Not many people nowadays get a chance to bargain with Merrill
+Tawney."
+
+Greg shrugged. "He named a price and I didn't like it."
+
+"Three times what the rig is worth," Coombs said.
+
+"That's what I didn't like," Greg said. "That outfit wouldn't give us a
+break like that just for old times' sake. Do you think they would?"
+
+"Well, I don't know," Johnny said slowly. "Back before they built the
+city here, they used to have rats getting into the grub. Came right down
+off the ships. Got rid of most of them, finally, but it seems to me
+we've still got some around, even if they've got different shapes now."
+He jerked his thumb toward the bedroom door. "In case you're wondering,
+that's why I was standin' back there all this time ... just to make sure
+you didn't sell out to Tawney no matter what price he offered."
+
+Tom jumped up excitedly. "Then you know something about Dad's accident!"
+
+"No, I can't say I do. I wasn't there."
+
+"Do you really think it was an accident?"
+
+"Can't prove it wasn't."
+
+"But at least you've got some ideas," Tom said.
+
+"Takes more than ideas to make a case," he said at length. "But there's
+one thing I do know. I've got no proof, not a shred of it, but I'm sure
+of one thing just as sure as I'm on Mars." He looked at the twins
+thoughtfully. "Your dad wasn't just prospecting, out in the Belt. He'd
+run onto something out there, something big."
+
+The twins looked at him. "Run onto something?" Greg said. "You mean...."
+
+"I mean I think your dad hit a Big Strike out there, rich metal, a real
+bonanza lode. Maybe the biggest strike that's ever been made," the miner
+said slowly. "And then somebody got to him before he could bring it in."
+
+
+
+
+3. Too Many Warnings
+
+
+For a moment, neither of the boys could say anything at all.
+
+From the time they had learned to talk, they had heard stories and tales
+that the miners and prospectors told about the Big Strike, the pot of
+gold at the end of the rainbow, the wonderful, elusive goal of every man
+who had ever taken a ship into the Asteroid Belt.
+
+For almost a hundred and fifty years ... since the earliest days of
+space exploration ... there had been miners prospecting in the
+Asteroids. Out there, beyond the orbit of Mars and inside the orbit of
+Jupiter, were a hundred thousand ... maybe a hundred million, for all
+anybody knew ... chunks of rock, metal and debris, spinning in silent
+orbit around the sun. Some few of the Asteroids were big enough to be
+called planets ... Ceres, five hundred miles in diameter; Juno, Vesta,
+Pallas, half a dozen more. A few hundred others, ranging in size from
+ten to a hundred miles in diameter, had been charted and followed in
+their orbits by the observatories, first from Earth's airless Moon, then
+from Mars. There were tens of thousands more that had never been
+charted. Together they made up the Asteroid Belt, spread out in space
+like a broad road around the sun, echoing the age-old call of the
+bonanza.
+
+For there was wealth in the Asteroids ... wealth beyond a man's wildest
+dreams ... if only he could find it.
+
+Earth, with its depleted iron ranges, its exhausted tin and copper
+mines, and its burgeoning population, was hungry for metal. Earth needed
+steel, tin, nickel, and zinc; more than anything, Earth needed
+ruthenium, the rare-earth catalyst that made the huge solar energy
+converters possible.
+
+Mars was rich in the ores of these metals ... but the ores were buried
+deep in the ground. The cost of mining them, and of lifting the heavy
+ore from Mars' gravitational field and carrying it to Earth was
+prohibitive. Only the finest carbon steel, and the radioactive metals,
+smelted and purified on Mars and transported to Earth, could be made
+profitable.
+
+But from the Asteroid Belt, it was a different story. There was no
+gravity to fight on the tiny asteroids. On these chunks of debris, the
+metals lay close to the surface, easy to mine. Ships orbiting in the
+Belt could fill their holds with their precious metal cargoes and
+transfer them in space to the interplanetary orbit-ships spinning back
+toward Earth. It was hard work, and dangerous work; most of the ore was
+low-grade, and brought little return. But always there was the lure of
+the Big Strike, the lode of almost-pure metal that could bring a fortune
+back to the man who found it.
+
+ * * * * *
+
+A few such strikes had been made. Forty years before a single claim had
+brought its owner seventeen million dollars in two years. A dozen other
+men had stumbled onto fortunes in the Belt ... but such metal-rich
+fragments were grains of sand in a mighty river. For every man who found
+one, a thousand others spent years looking and then perished in the
+fruitless search.
+
+And now Johnny Coombs was telling them that their father had been one of
+that incredible few.
+
+"You really think Dad hit a bonanza lode out there?"
+
+"That's what I said."
+
+"Did you see it with your own eyes?"
+
+"No."
+
+"You weren't even out there with him!"
+
+"No."
+
+"Then why are you so sure he found something?"
+
+"Because he told me so," Johnny Coombs said quietly.
+
+The boys looked at each other. "He actually _said_ he'd found a rich
+lode?" Tom asked eagerly.
+
+"Not exactly," Johnny said. "Matter of fact, he never actually told me
+_what_ he'd found. He needed somebody to sign aboard the _Scavenger_
+with him in order to get a clearance to blast off, but he never did plan
+to take me out there with him. 'I can't take you now, Johnny,' he told
+me. 'I've found something out there, but I've got to work it alone for a
+while.' I asked him what he'd found, and he just gave me that funny
+little grin of his and said, 'Never mind what it is, it's big enough for
+both of us. You just keep your mouth shut, and you'll find out soon
+enough.' And then he wouldn't say another word until we were homing in
+on the shuttle ship to drop me off."
+
+Johnny finished his coffee and pushed the cup aside. "I knew he wasn't
+joking. He was excited, and I think he was scared, too. Just before I
+left him, he said, 'There's one other thing, Johnny. Things might not
+work out quite the way I figure them, and if they don't ... make sure
+the twins know what I've told you.' I told him I would, and headed back.
+That was the last I heard from him until the Patrol ship found him
+floating in space with a torn-open suit and a ruined scooter floating a
+few miles away."
+
+"Do you think that Jupiter Equilateral knew Dad had found something?"
+Tom asked.
+
+"Who knows? I'm sure that _he_ never told them, but it's awful hard to
+keep a secret like that, and they sound awful eager to buy that rig,"
+Johnny Coombs said.
+
+"Yes, and it doesn't make sense. I mean, if they were responsible for
+Dad's accident, why didn't they just check in for him on schedule and
+then quietly bring in their rig to jump the claim?"
+
+"Maybe they couldn't find it," Johnny said. "If they'd killed your dad,
+they wouldn't have dared hang around very long right then. Even if
+they'd kept the signal going, a Patrol ship might have come into the
+region any time. And if a U.N. Patrol ship ever caught them working a
+dead man's claim without reporting the dead man, the suit would really
+start to leak." Johnny shook his head. "Remember, your Dad had a dozen
+claims out there. They might have had to scout the whole works to find
+the right one. Much easier to do it out in the open, with your
+signatures on a claim transfer. But one thing is sure ... if they _knew_
+what Roger found out there, and where it was, Tawney would never be
+offering you triple price for the rig."
+
+"Then whatever Dad found is still out there," Tom said.
+
+"I'd bet my last dime on it."
+
+"There might even be something to show that the accident wasn't an
+accident," Tom went on. "Something even the Major would have to admit
+was evidence."
+
+Johnny Coombs pursed his lips, looking up at Tom. "Might be," he
+conceded.
+
+"Well, what are we waiting for? We turned Tawney's offer down ... he
+might be sending a crew out to jump the claim right now."
+
+"If he hasn't already," Johnny said.
+
+"Then we've got to get out there."
+
+Johnny turned to Greg. "You could pilot us out and handle the
+navigation, and as for Tom...."
+
+"As for Tom, he could get sick all over the place and keep us busy just
+taking care of him," Greg said sourly. "You and me, yes. Not Tom. You
+don't know that boy in a spaceship."
+
+Tom started to his feet, glaring at his brother. "That's got nothing to
+do with it...."
+
+"It's true, isn't it? You'd be a big help out there."
+
+Johnny looked at Tom. "You always get sick in free fall?"
+
+"Look, let's be reasonable," Greg said. "You'd just be in the way. There
+are plenty of things you could do right here, and Johnny and I could
+handle the rig alone...."
+
+Tom faced his brother angrily. "If you think I'm going to stay here and
+keep myself company, you're crazy," he said. "This is one show you're
+not going to run, so just quit trying. If you go out there, I go."
+
+Greg shrugged. "Okay, Twin. It's your stomach, not mine."
+
+"Then let me worry about it."
+
+"I hope," Johnny said, "that that's the worst we have to worry about.
+Let's get started planning."
+
+ * * * * *
+
+Time was the factor uppermost in their minds. They knew that even under
+the best of conditions, it could take weeks to outfit and prepare for a
+run out to the Belt. A ship had to be leased and fueled; there were
+supplies to lay in. There was the problem of clearance to take care of,
+claims to be verified and spotted, orbit coordinates to be computed and
+checked ... a thousand details to be dealt with, anyone of which might
+delay embarkation from an hour to a day or more.
+
+It was not surprising that Tom and Greg were dubious when Johnny told
+them they could be ready to clear ground in less than twenty-four hours.
+Even knowing that Merrill Tawney might already have a mining crew at
+work on Roger Hunter's claims, they could not believe that the red tape
+of preparation and clearance could be cut away so swiftly.
+
+They underestimated Johnny Coombs.
+
+Six hours after he left them, he was back with a signed lease giving
+them the use of a scout-ship and fuel to take them out to the Belt and
+back again; the ship was in the Sun Lake City racks waiting for them
+whenever they were ready.
+
+"What kind of a ship?" Greg wanted to know.
+
+"A Class III Flying Dutchman with overhauled atomics and hydrazine
+side-jets," Johnny said, waving the transfer order. "Think you can fly
+it?"
+
+Greg whistled. "Can I? I trained in a Dutchman ... just about the
+fastest scouter there is. What condition?"
+
+"Lousy ... but it's fueled, with six weeks' supplies in the hold, and it
+doesn't cost us a cent. Courtesy of a friend. You'll have to check it
+over, but it'll do."
+
+They inspected the ship, a weatherbeaten scouter that looked like a
+relic of the '90's. Inside there were signs of many refittings and
+overhauls, but the atomics were well shielded, and it carried a
+surprising chemical fuel auxiliary for the cabin size. Greg disappeared
+into the engine room, and Tom and Johnny left him testing valves and
+circuits while they headed down to the U.N. Registry office in the
+control tower.
+
+On the way Johnny outlined the remaining outfitting steps. Tom would be
+responsible for getting the clearance permit through Registry; Johnny
+would check out all supplies, and then contact the observatory for the
+orbit coordinates of Roger Hunter's claims.
+
+"I thought the orbits were mapped on the claim papers," Tom said. "I
+mean, every time an asteroid is claimed, the orbit has to be
+charted...."
+
+"That's right, but the orbit goes all the way around the sun. We know
+where the _Scavenger_ was when the Patrol ship found her ... but she's
+been travelling in orbit ever since. The observatory computer will
+pinpoint her for us and chart a collision course so we can cut out and
+meet her instead of trailing her for a week. Do you have the crew-papers
+Greg and I signed?"
+
+"Right here."
+
+They were stepping off the ramp below the ship when a man loomed up out
+of the shadows. It was a miner Tom had never seen before. Johnny nodded
+as he approached. "Any news, Jack?"
+
+"Quiet as a church," the man said.
+
+"We'll be held up another eight hours at least," Johnny said. "Don't go
+to sleep on us, Jack."
+
+"Don't worry about us sleepin'," the man said grimly. "There's been
+nobody around but yourselves, so far ... except the clearance
+inspector."
+
+Johnny looked up sharply. "You check his papers?"
+
+"_And_ his prints. He was all right."
+
+Johnny took Tom's arm, and they headed through the gate toward the
+control tower. "I guess I'm just naturally suspicious," he grinned, "but
+I'd sure hate to have a broken cut-off switch, or a fuel valve go out of
+whack at just the wrong moment."
+
+"You think Tawney would dare to try something here?" Tom said.
+
+"Never hurts to check. We've got our hands full for a few hours getting
+set, so I just asked my friends to keep an eye on things. Always did say
+that a man who's going to gamble is smart to cover his bets."
+
+At the control tower they parted, and Tom walked into the clearance
+office. Johnny's watch-man had startled him, and for the first time he
+felt a chill of apprehension. If they were right ... if this trip to the
+Belt were not a wild goose chase from the very start ... then Roger
+Hunter's accident had been no accident at all.
+
+Quite suddenly, Tom felt very thankful that Johnny Coombs had
+friends....
+
+ * * * * *
+
+"I don't like it," the Major said, facing Tom and Greg across the desk
+in the U.N. Registry office below the control tower. "You've gotten an
+idea in your heads, and you just won't listen to reason."
+
+Somewhere above them, Tom could hear the low-pitched rumble of a
+scout-ship blasting from its launching rack. "All we want to do is go
+out and work Dad's claim," he said for the second time.
+
+"I know perfectly well what you want to do, that's why I told the people
+here to alert me if you tried to clear a ship. You don't know what
+you're doing ... and I'm not going to sign those clearance papers."
+
+"Why not?" Greg said.
+
+"Because you're going out there asking for trouble, that's why not."
+
+"But you told us before that there wasn't any trouble. Dad had an
+accident, that was all. So how could we get in trouble?"
+
+The Major's face was an angry red. He started to say something, then
+stopped, and scowled at them instead. They met his stare. Finally he
+threw up his hands. "All right, so I can't legally stop you," he said.
+"But at least I can beg you to use your heads. You're wasting time and
+money on a foolish idea. You're walking into dangers and risks that you
+can't handle, and I hate to see it happen.
+
+"Mining in the Belt is a job for experienced men, not rank novices."
+
+"Johnny Coombs is no novice."
+
+"No, but he's lost his wits, taking you two out there."
+
+"Well, are there any other dangers you have in mind?"
+
+Once more the Major searched for words, and failed to find them. "No,"
+he sighed, "and you wouldn't listen if I did."
+
+"It seems everybody is warning us about how dangerous this trip is
+likely to be," Greg said quietly. "Last night it was Merrill Tawney. He
+offered to buy us out, he was so eager for a deal that he offered us a
+fantastic price. Then Johnny tells us that Dad mined some rich ore when
+he was out there on his last trip, but never got a chance to bring it in
+because of his ... accident. Up until now I haven't been so sure Dad
+_didn't_ just have an accident, but now I'm beginning to wonder. Too
+many people have been warning us...."
+
+"You're determined to go out there, then?"
+
+"That's about right."
+
+The Major picked up the clearance papers, glanced at them quickly,
+and signed them. "All right, you're cleared. I hate to do it, but I
+suppose I'd go with you if the law would let me. And I'll tell you one
+thing ... if you can find a single particle of evidence that will link
+Jupiter Equilateral or anybody else to your father's death, I'll use all
+the power I have to break them." He handed the papers back to Tom. "But
+be careful, because if Jupiter Equilateral is involved in it, they're
+going to play dirty."
+
+At the door he turned. "Good trip, and good luck."
+
+Tom folded the papers and stuck them thoughtfully into his pocket.
+
+They met Johnny Coombs in the Registry offices upstairs; Tom patted his
+pocket happily. "We're cleared in forty-five minutes," he said.
+
+Johnny grinned. "Then we're all set." They headed up the ramp, reached
+ground level, and started out toward the launching racks.
+
+At the far end of the field a powerful Class I Ranger, one of the
+Jupiter Equilateral scout fleet, was settling down into its slot in a
+perfect landing maneuver. The triangle-and-J-insignia gleamed brightly
+on her dark hull. She was a rich, luxurious-looking ship. Many miners on
+Mars could remember when Jupiter Equilateral had been nothing more than
+a tiny mining company working claims in the remote "equilateral" cluster
+of asteroids far out in Jupiter's orbit. Gradually the company had grown
+and flourished, accumulating wealth and power as it grew, leaving behind
+it a thousand half-confirmed stories of cheating, piracy, murder and
+theft. Other small mining outfits had fallen by the wayside until now
+over two-thirds of all asteroid mining claims were held by Jupiter
+Equilateral, and the small independent miners were forced more and more
+to take what was left.
+
+They reached the gate to the Dutchman's launching slot and entered.
+
+Inside the ship Tom and Johnny strapped down while Greg made his final
+check-down on the engines, gyros and wiring. The cabin was a tiny vault,
+with none of the spacious "living room" of the orbit-ships. Tom leaned
+back in the accelleration cot, and listened to the count-down signals
+that came at one minute intervals now. In the earphones he could hear
+the sporadic chatter between Greg and the control tower. No hint that
+this was anything but a routine blastoff....
+
+But there was trouble ahead, Tom was certain of that. Everybody on Mars
+was aware that Roger Hunter's sons were heading out to the Belt to pick
+up where he had left off. Greg had secured a leave of absence from
+Project Star-Jump ... unhappily granted, even though his part in their
+program had already been disrupted. Even they had heard the rumors that
+were adrift....
+
+And if there was trouble now, they were on their own. The Asteroid Belt
+was a wilderness, untracked and unexplored, and except for an almost
+insignificant fraction, completely unknown. If there was trouble out
+there, there would be no one to help.
+
+Somewhere below the engines roared, and Tom felt the weight on his
+chest, sudden and breath-taking.
+
+They were on their way.
+
+
+
+
+4. "Between Mars and Jupiter...."
+
+
+After all the tension of preparing for it, the trip out seemed
+interminable.
+
+They were all impatient to reach their destination. During blastoff and
+accelleration they had watched Mars dwindle to a tiny red dot; then time
+seemed to stop altogether, and there was nothing to do but wait.
+
+For the first eight hours of free fall, after the engines had cut out,
+Tom was violently ill. He fought it desperately, gulping the pills
+Johnny offered and trying to keep them down. Gradually the waves of
+nausea subsided, but it was a full twenty-four hours before Tom felt
+like stirring from his cot to take up the shipboard routine.
+
+And then there was nothing for him to do. Greg handled the navigation
+skilfully, while Johnny kept radio contact and busied himself in the
+storeroom, so Tom spent hours at the viewscreen. On the second day he
+spotted a tiny chunk of rock that was unquestionably an asteroid moving
+swiftly toward them. It passed at a tangent ten thousand miles ahead of
+them, and Greg started work at the computer, feeding in the data tapes
+that would ultimately guide the ship to its goal.
+
+ * * * * *
+
+Pinpointing a given spot in the Asteroid Belt was a gargantuan task,
+virtually impossible without the aid of the ship's computer to compute
+orbits, speeds, and distances. Tom spent more and more time at the
+viewscreen, searching the blackness of space for more asteroid
+sightings. But except for an occasional tiny bit of debris hurtling by,
+he saw nothing but the changeless panorama of stars.
+
+Johnny Coombs found him there on the third day, and laughed at his sour
+expression. "Gettin' impatient?"
+
+"Just wondering when we'll reach the Belt, is all," Tom said.
+
+Johnny chuckled. "Hope you're not holdin' your breath. We've already
+been _in_ the Belt for the last forty-eight hours."
+
+"Then where are all the asteroids?" Tom said.
+
+"Oh, they're here. You just won't see many of them. People always think
+there ought to be dozens of them around, like sheep on a hillside, but
+it just doesn't work that way." Johnny peered at the screen. "Of course,
+to an astronomer the Belt is just loaded ... hundreds of thousands of
+chunks, all sizes from five hundred miles in diameter on down. But
+actually, those chunks are all tens of thousands of miles apart, and the
+Belt _looks_ just as empty as the space between Mars and Earth."
+
+"Well, I don't see how we're ever going to find one particular rock,"
+Tom said, watching the screen gloomily.
+
+"It's not too hard. Every asteroid has its own orbit around the sun, and
+everyone that's been registered as a claim has the orbit charted. The
+one we want isn't where it was when your Dad's body was found ... it's
+been travelling in its orbit ever since. But by figuring in the fourth
+dimension, we can locate it."
+
+Tom blinked. "Fourth dimension?"
+
+"Time," Johnny Coombs said. "If we just used the three linear
+dimensions ... length, width and depth ... we'd end up at the place where
+the asteroid _was_, but that wouldn't help us much because it's been
+moving in orbit ever since the Patrol Ship last pinpointed it. So we
+figure in a fourth dimension ... the time that's passed since it was last
+spotted ... and we can chart a collision course with it, figure out just
+where _we'll_ have to be to meet it."
+
+It was the first time that the idea of time as a "dimension" had ever
+made sense to Tom. They talked some more, until Johnny started bringing
+in fifth and sixth dimensions, and problems of irrational space and
+hyperspace, and got even himself confused.
+
+"Anyway," Tom said, "I'm glad we've got a computer aboard."
+
+"And a navigator," Johnny added. "Don't sell your brother short."
+
+"Fat chance of that. Greg would never stand for it."
+
+Johnny frowned. "You lads don't like each other very much, do you?" he
+said.
+
+Tom was silent for a moment. Then he looked away. "We get along, I
+guess."
+
+"Maybe. But sometimes just gettin' along isn't enough. Especially when
+there's trouble. Give it a thought, when you've got a minute or two...."
+
+Later, the three of them went over the computer results together. Johnny
+and Greg fed the navigation data into the ship's drive mechanism,
+checking and rechecking speeds and inclination angles. Already the
+Dutchman's orbital speed was matching the speed of Roger Hunter's
+asteroid ... but the orbit had to be tracked so that they would arrive
+at the exact point in space to make contact. Tom was assigned to the
+viewscreen, and the long wait began.
+
+He spotted their destination point an hour before the computer had
+predicted contact ... at first a tiny pinpoint of reflected light in the
+scope, gradually resolving into two pinpoints, then three in a tiny
+cluster. Greg cut in the rear and lateral jets momentarily, stabilizing
+their contact course; the dots grew larger.
+
+Ten minutes later, Tom could see their goal clearly in the
+viewscreen ... the place where Roger Hunter had died.
+
+ * * * * *
+
+It was neither large nor small for an asteroid, an irregular chunk of
+rock and metal, perhaps five miles in diameter, lighted only by the dull
+reddish glow from the dime-sized sun. Like many such jagged chunks of
+debris that sprinkled the Belt, this asteroid did not spin on any axis,
+but constantly presented the same face to the sun.
+
+Just off the bright side the orbit-ship floated, stable in its orbit
+next to the big rock, but so small in comparison that it looked like a
+tiny glittering toy balloon. And clamped on its rack on the orbit-ship's
+side, airlock to airlock, was the _Scavenger_, the little scout ship
+that Roger Hunter had brought out from Mars on his last journey.
+
+While Greg maneuvered the Dutchman into the empty landing rack below the
+_Scavenger_ on the hull of the orbit-ship, Johnny scanned the blackness
+around them through the viewscope, a frown wrinkling his forehead.
+
+"Do you see anybody?" Tom asked.
+
+"Not a sign ... but I'm really looking for other rocks. I can see three
+that aren't too far away, but none of them have claim marks. This one
+must have been the only one Roger was working."
+
+They stared at the ragged surface of the planetoid. Raw veins of
+metallic ore cut through it with streaks of color, but most of the
+sun-side showed only the dull gray of iron and granite. There was
+nothing unusual about the surface that Tom could see. "Could there be
+anything on the dark side?"
+
+"Could be," Johnny said. "We'll have to go over it foot by foot ... but
+first, we should go through the orbit-ship and the _Scavenger_. If the
+Patrol ship missed anything, we want to know it."
+
+The interior of the orbit-ship was dark. It spun slowly on its axis,
+giving them just enough weight so they would not float free whenever
+they moved. Their boots clanged on the metal decks as they climbed up
+the curving corridor toward the control cabin.
+
+Then Johnny threw a light switch, and they stared around them in
+amazement.
+
+The cabin was a shambles. Everything that was not bolted down had been
+ripped open and thrown aside.
+
+Greg whistled through his teeth. "The Major said the Patrol crew had
+gone through the ship ... but he didn't say they'd wrecked it."
+
+"They didn't," Johnny said grimly. "No Patrol ship would ever do this.
+Somebody else has been here since." He turned to the control panel,
+flipped switches, checked gauges. "Hydroponics are all right. Atmosphere
+is still good; we can take off these helmets. Fuel looks all right,
+storage holds ..." He shook his head. "They weren't looting, but they
+were looking for something, all right. Let's look around and see if they
+missed anything."
+
+It took them an hour to survey the wreckage. Not a compartment had been
+missed. Even the mattresses on the accelleration cots had been torn
+open, the spring-stuffing tossed about helter-skelter. Tom went through
+the lock into the _Scavenger_; the scout ship too had been searched,
+rapidly but thoroughly.
+
+But there was no sign of anything that Roger Hunter might have found.
+
+Back in the control cabin Johnny was checking the ship's log. The old
+entries were on microfilm, stored on their spools near the reader. More
+recent entries were still recorded on tape. From the jumbled order,
+there was no doubt that marauders had examined them. Johnny ran through
+them nevertheless, but there was nothing of interest. Routine
+navigational data; a record of the time of contact with the asteroid; a
+log of preliminary observations on the rock; nothing more. The last tape
+recorded the call-schedule Roger Hunter had set up with the Patrol, a
+routine precaution used by all miners, to bring help if for some reason
+they should fail to check in on schedule.
+
+There was no hint in the log of any extraordinary discovery.
+
+"Are any tapes missing?" Greg wanted to know.
+
+"Doesn't look like it. There's one here for each day-period."
+
+"I wonder," Tom said. "Dad always kept a personal log. You know, a sort
+of a diary, on microfilm." He peered into the film storage bin, checked
+through the spools. Then, from down beneath the last row of spools he
+pulled out a slightly smaller spool. "Here's something our friends
+missed, I bet."
+
+It was not really a diary, just a sequence of notes, calculations and
+ideas that Roger Hunter had jotted down and microfilmed from time to
+time. The entries on the one spool went back for several years. Tom fed
+the spool into the reader, and they stared eagerly at the last few
+entries.
+
+A series of calculations, covering several pages, but with no notes to
+indicate what, exactly, Roger Hunter had been calculating. "Looks like
+he was plotting an orbit," Greg said. "But what orbit? And why? Nothing
+here to tell."
+
+"It must have been important, though, or Dad wouldn't have filmed the
+pages," Tom said. "Anything else?"
+
+Another sheet with more calculations. Then a short paragraph written in
+Roger Hunter's hurried scrawl. "No doubt now what it is," the words
+said. "Wish Johnny were here, show him a _real_ bonanza, but he'll know
+soon enough if...."
+
+They stared at the scribbled, uncompleted sentence. Then Johnny Coombs
+let out a whoop. "I told you he found something! And he found it _here_,
+not somewhere else."
+
+"Hold it," Greg said, peering at the film reader. "There's something
+more on the last page, but I can't read it."
+
+Tom blinked at the entry. "'Inter Jovem et Martem planetam interposui,'"
+he read. He scratched his head. "That's Latin, and it's famous, too.
+Kepler wrote it, back before the asteroids were discovered. 'Between
+Jupiter and Mars I will put a planet.'"
+
+Greg and Johnny looked at each other. "I don't get it," Greg said.
+
+"Dad told me about that once," Tom said. "Kepler couldn't understand
+the long jump between Mars and Jupiter, when Venus and Earth and Mars
+were so close together. He figured there ought to be a planet out
+here ... and he was right, in a way. There wasn't any one planet, unless
+you'd call Ceres a planet, but it wasn't just empty space between Mars
+and Jupiter either. The asteroids were here."
+
+"But why would Dad be writing that down?" Greg asked. "And what has it
+got to do with what he found out here?" He snapped off the reader switch
+angrily. "I don't understand any of this, and I don't like it. If Dad
+found something out here, where is it? And who tore this ship apart
+after the Patrol ship left?"
+
+"Probably the same ones that caused the 'accident' in the first place,"
+Johnny said.
+
+"But why did they come back?" Greg protested. "If they killed Dad, they
+must have known what he'd found before they killed him."
+
+"You'd think so," Johnny conceded.
+
+"Then why take the risk of coming back here again?"
+
+"Maybe they _didn't_ know," Tom said thoughtfully.
+
+"What do you mean?"
+
+"I mean maybe they killed him too soon. Maybe they thought they knew
+what he'd found and where it was ... and then found out that they
+didn't, after all. Maybe Dad hid it...."
+
+Johnny Coombs shook his head. "No way a man can hide an ore strike."
+
+"But suppose Dad did, somehow, and whoever killed him couldn't find it?
+It would be too late to make him tell them. They'd _have_ to come back
+and look again, wouldn't they? And from the way they went about it, it
+looks as though they weren't having much luck."
+
+"Then whatever Dad found would still be here, somewhere," Greg said.
+
+"That's right."
+
+"But where? There's nothing on this ship."
+
+"Maybe not," Tom said, "but I'd like to take a look at that asteroid
+before we give up."
+
+ * * * * *
+
+They paused in the big ore-loading lock to reclamp their pressure
+suit helmets, and looked down at the jagged chunk of rock a hundred
+yards below them. In the lock they had found scooters ... the little
+one-man propulsion units so commonly used for short distance work in
+space ... but decided not to use them. "They're clumsy," Johnny said,
+"and the bumper units in your suits will do just as well for this
+distance." He looked down at the rock. "I'll take the center section.
+You each take an edge and work in. Look for any signs of work on the
+surface ... chisel marks, Murexide charges, anything."
+
+"What about the dark side?" Greg asked.
+
+"If we want to see anything there, we'll either have to rig up lights or
+turn the rock around," Johnny said. "Let's cover this side first and see
+what we come up with."
+
+He turned and leaped from the airlock, moving gracefully down toward
+the surface, using the bumper unit to guide himself with short bursts
+of compressed CO_{2}, from the nozzle. Greg followed, pushing off
+harder and passing Johnny halfway down. Tom hesitated. It looked easy
+enough ... but he remembered the violent nausea of his first few hours
+of free fall.
+
+Finally he gritted his teeth and jumped off after Greg. Instantly he
+knew that he had jumped too hard. He shot away from the orbit-ship like
+a bullet; the jagged asteroid surface leaped up at him. Frantically he
+grabbed for the bumper nozzle and pulled the trigger, trying to break
+his fall.
+
+He felt the nozzle jerk in his hand, and then, abruptly, he was spinning
+off at a wild tangent from the asteroid, head over heels. For a moment
+it seemed that asteroid, orbit-ship and stars were all wheeling crazily
+around him. Then he realized what had happened. He fired the bumper
+again, and went spinning twice as fast. The third time he timed the
+blast, aiming the nozzle carefully, and the spinning almost stopped.
+
+He fought down nausea, trying to get his bearings. He was three hundred
+yards out from the asteroid, almost twice as far from the orbit-ship. He
+stared down at the rock as he moved slowly away from it. Before, from
+the orbit-ship, he had been able to see only the bright side of the huge
+rock; now he could see the sharp line of darkness across one side.
+
+But there was something else....
+
+He fired the bumper again to steady himself, peering into the blackness
+beyond the light-line on the rock. He snapped on his helmet lamp, aimed
+the spotlight beam down to the dark rock surface. Greg and Johnny were
+landing now on the bright side, with Greg almost out of sight over the
+"horizon" ... but Tom's attention was focussed on something he could see
+only now as he moved away from the asteroid surface.
+
+His spotlight caught it ... something bright and metallic, completely
+hidden on the dark side, lying in close to the surface but not quite on
+the surface. Then suddenly Tom knew what it was ... the braking jets of
+a Class I Ranger, crouching beyond the reach of sunlight in the shadow
+of the asteroid....
+
+Swiftly he fired the bumper again, turning back toward the orbit-ship.
+His hand went to the speaker-switch, but he caught himself in time. Any
+warning shouted to Greg and Johnny would certainly be picked up by the
+ship. But he had to give warning somehow.
+
+He tumbled into the airlock, searching for a flare in his web belt. It
+was a risk ... the Ranger ship might pick up the flash ... but he had to
+take it. He was unscrewing the fuse cap from the flare when he saw Greg
+and Johnny leap up from the asteroid surface.
+
+Then he saw what had alarmed them. Slowly, the Ranger was moving out
+from its hiding place behind the rock. Tom reached out to catch Greg as
+he came plummeting into the lock. There was a flash from the Ranger's
+side, and Johnny Coombs' voice boomed in his earphones: "Get inside! Get
+the lock closed, fast ... hurry up, can't waste a second."
+
+Johnny caught the lip of the lock, dragged himself inside frantically.
+They were spinning the airlock door closed when they heard the
+thundering explosion, felt the ship lurch under their feet, and all
+three of them went crashing to the deck.
+
+
+
+
+5. The Black Raider
+
+
+For a stunned moment they were helpless as they struggled to pick
+themselves up. The stable airlock deck was suddenly no longer
+stable ... it was lurching back and forth like a rowboat on a heavy sea,
+and they grabbed the shock-bars along the bulkheads to steady themselves.
+"What happened?" Greg yelped. "I saw a ship...."
+
+As if in answer there was another crash belowdecks, and the lurching
+became worse. "They're firing on us, that's what happened," Johnny
+Coombs growled.
+
+"Well, they're shaking us loose at the seams," Greg said. "We've got to
+get this crate out of here." He reached for his helmet, began unsnapping
+his pressure suit.
+
+"Leave it on," Johnny snapped.
+
+"But we can't move fast enough in these things...."
+
+"Leave it on all the same. If they split the hull open, you'll be dead
+in ten seconds without a suit."
+
+Somewhere below they heard the steady _clang-clang-clang_ of the
+emergency-station's bell ... already one of the compartments somewhere
+had been breached, and was pouring its air out into the vacuum of space.
+"But what can we do?" Greg said. "They could tear us apart!"
+
+"First, we see what they've already done," Johnny said, spinning the
+wheel on the inner lock. "If they plan to tear us apart, we're done for,
+but they may want to try to board us.... We'll wait and see."
+
+An orbit-ship under fire was completely vulnerable. One well-placed
+shell could rip it open like a balloon.
+
+Tom and Greg followed Johnny to where the control cabin was located. In
+control they found alarm lights flashing in three places on the
+instrument panel. Another muffled crash roared through the ship, and a
+new row of lights sprang on along the panel.
+
+"How are the engines?" Greg said, staring at the flickering lights.
+
+"Can't tell. Looks like they're firing at the main jets, but they've
+ripped open three storage holds, too. They're trying to disable us...."
+
+"What about the _Scavenger_?"
+
+Johnny checked a gauge. "The airlock compartment is all right, so the
+scout ships haven't been touched. They couldn't fire on them without
+splitting the whole ship down the middle." Johnny leaned forward,
+flipped on the viewscreen, and an image came into focus.
+
+ * * * * *
+
+It was a Class I Ranger, and there was no doubt of its origin. Like the
+one they had seen berthing at the Sun Lake City racks, this ship had a
+glossy black hull, with the golden triangle-and-J insignia standing out
+in sharp relief in the dim sunlight.
+
+"It's our friends, all right," Johnny said.
+
+"But what are they trying to do?" Tom said.
+
+Even as they watched, a pair of scooters broke from the side of the
+Ranger and slid down toward the sun side of the asteroid. "I don't
+know," Johnny said. "I think they intended to stay hidden, until Tom
+lost control of his bumper, and got far enough around there to spot
+them." He frowned as the first scooter touched down on the asteroid
+surface.
+
+"Can't we fire on them?" Greg said angrily.
+
+"Not the way this tub is lurching around. They've got our main gyros,
+and the auxilliaries aren't powerful enough to steady us. Another blast
+or two could send us spinning like a top, and we'd have nothing to
+stabilize us...."
+
+There was another flash from the Ranger's hull, and the ship jerked
+under their feet. "Well, we're a sitting duck here," Greg said. "Maybe
+those engines will still work." He slid into the control seat, flipped
+the drive switches to fire the side jets in opposite pairs. They fired,
+steadying the lurching of the ship somewhat, but there was no response
+from the main engines. "No good. We couldn't begin to run from them.
+We're stuck here."
+
+"They could outrun us anyway," Tom said, watching the viewscreen. "And
+they're moving in closer now."
+
+"They're going to board us," Tom said.
+
+Johnny nodded, his eyes suddenly bright. "I think you're right. And if
+they do, we may have a chance. But we've got to split up.... Greg, you
+take the control cabin here, try to keep them out if you can. Tom can
+cover the main corridor to the storage holds, and I'll take the engine
+room section. That will sew up the entrances to control, here, and give
+us a chance to stop them."
+
+"They may have a dozen men," Tom said. "They could just shoot us down."
+
+"I don't think so," Johnny said. "They want _us_, not the ship, or they
+wouldn't bother to board us. We may not be able to hold them off, but we
+can try."
+
+"What about making a run for it in the _Scavenger_?" Greg said.
+
+Johnny chuckled grimly. "It'd be a mighty short run. That Ranger's got
+homing shells that could blow the _Scavenger_ to splinters if we tried
+it. Our best bet is to put up such a brawl that they think twice about
+taking us."
+
+They parted in the corridor outside control, Johnny heading down for the
+engine room corridors, while Tom ran up toward the main outer-shell
+corridor, a Markheim stunner in his hand. The entire outer shell of the
+ship was storage space, each compartment separately sealed and connected
+with the two main corridors that circled the ship. On each side these
+corridors came together to join the short entry corridors from the
+scout-ship airlocks.
+
+Tom knew that the only way the ship could be boarded was through those
+locks; a man stationed at the place where the main corridors joined
+could block any entry from the locks ... as long as he could hold his
+position. Tom reached the junction of the corridors, and crouched close
+to the wall. By peering around the corner, he had a good view of the
+airlock corridor.
+
+Tom gripped the Markheim tightly, and he dialed it down to a narrow
+beam. Nobody had ever been killed by a stunner ... but a direct hit with
+a narrow beam could paralyze a man for three days.
+
+There was movement at the far end of the airlock corridor. A helmeted
+head peered around the turn in the corridor; then two men in pressure
+suits moved into view, walking cautiously, weapons in hand. Tom shrank
+back against the wall, certain they had not seen him. He waited until
+they were almost to the junction with the main corridor; then he took
+aim and pressed the trigger stud on his Markheim. There was an ugly
+ripping sound as the gun jerked in his hand. The two men dropped as
+though they had been pole-axed.
+
+A shout, a scrape of metal against metal, and a shot ripped back at him
+from the end of the corridor. Tom jerked back fast, but not quite fast
+enough. He felt a sledge-hammer blow on his shoulder, felt his arm jerk
+in a cramping spasm while the corridor echoed the low rumble of
+sub-sonics. He flexed his arm to work out the spasm ... they were using
+a wide beam, hardly strong enough to stun a man. His heart pounded. They
+were being careful, very careful....
+
+Two more men rounded the bend in the corridor. Tom fired, but they hit
+the deck fast, and the beam missed. The first one jerked to his feet,
+charged up the corridor toward him, dodging and sliding. Tom followed
+him in his sights, fired three times as the Markheim heated up in his
+hand. The beam hit the man's leg, dumping him to the deck, and bounced
+off to catch the second one.
+
+But now there was another sound, coming from the corridor behind him.
+Voices, shouts, clanging of boots. He pressed against the wall,
+listening. The sounds were from below. They must have gotten past
+Johnny ... probably the men on the scooters. Tom looked around
+helplessly. If they came up behind him, he was trapped in a crossfire.
+But if he left his position, more men could come in through the airlock.
+Even now two more came around the bend, starting up the corridor for
+him....
+
+Quite suddenly, the lights went out.
+
+The men stopped. Sound stopped. The corridor was pitch black. Tom fired
+wildly down the corridor, heard shouts and oaths from the men, but he
+could see nothing. Then, ahead, a flicker of light as a headlamp went
+on. The men from the airlock were close, moving in on him, and from
+behind he saw light bouncing off the corridor walls....
+
+He jerked open the hatch to a storage hold, ducked inside, and slammed
+the hatch behind him. He pressed against the wall, panting.
+
+He waited.
+
+Suddenly an idea flickered in Tom's mind.
+
+It was a chance ... a long chance ... but it was something. If they were
+going to be captured in spite of anything they could do, even a long
+chance would be worth trying....
+
+He waited in the darkness, tried to think it through. It was a wild
+idea, an utterly impossible idea, he had never heard of it being tried
+before ... but _any_ chance was better than none. He remembered what
+Johnny had said in the control cabin. The Ranger ship would have homing
+shells. An attempt to make a run with the _Scavenger_ might be
+disastrous.
+
+He thought about it, trying to reason it out. The Jupiter Equilateral
+men obviously wanted them alive. They did not dare to kill Roger
+Hunter's sons, because Roger Hunter might have told them where the
+bonanza was. And Jupiter Equilateral would not dare let anyone of them
+break away. If one of them got back to Mars, the whole U.N. Patrol would
+be out in the Belt....
+
+The plan became clear in his mind, but he had to let Greg know. He
+fingered the control of his helmet radio. The boarding party would have
+a snooper, but if he was quick, they wouldn't have time to nail him. He
+buzzed an attention code. "Greg? Can you hear me?"
+
+Silence. He buzzed again, and waited. What was wrong? Had they already
+broken through to the control cabin and taken Greg? He buzzed again.
+"Greg! Sound off if you can hear me."
+
+More silence. Then a click. "Tom?"
+
+"Here. Are you all right?"
+
+"So far. You?"
+
+"They got past me, but they didn't hit me. How's Johnny?"
+
+"I don't know," Greg said. "I think he's been hurt. Tom, you'd better
+get off, they'll have snoopers...."
+
+"All right, listen," Tom said. "How does it look to you?"
+
+"Bad. We're outnumbered, they'll be through to here any minute."
+
+"All right, I've got an idea. It's risky, but it might let us pull
+something out of this mess. I'll need some time, though."
+
+"How much?"
+
+"Ten, fifteen minutes."
+
+There was an edge to Greg's voice. "What are you planning?"
+
+"I can't tell you, they're listening in. But if it works...."
+
+"Look, don't do anything stupid."
+
+"I can't hear you," Tom said. "You try to hold them for fifteen
+minutes ... and don't worry. Take care of yourself."
+
+Tom snapped off the speaker and moved to the hatchway. The corridor was
+empty, and pitch black. He started down toward the airlock, then stopped
+short at the sound of voices and the flicker of headlamps up ahead.
+
+He crouched back, but the lights were not moving. Guards at the lock,
+making certain that nobody tried to board their own ship. Tom grinned to
+himself. They weren't missing any bets, he thought.
+
+Except one. There was one bet they wouldn't even think of.
+
+He backtracked to the storage hold, crossed through it, and out into the
+far corridor. He followed the gentle curve of the deck a quarter of the
+way around the ship. Twice along the way he stumbled in the darkness,
+but saw no sign of the raiders. At last he reached the far side, and the
+corridor leading to No. 2 airlock. Again he could see the lamps of the
+guards around the bend; they were stationed directly inside their own
+lock.
+
+Inching forward, he peered into blackness. Each step made a muffled
+clang on the deck plates. He edged his boots along as quietly as
+possible, reaching along the wall with his hand until he felt the lip of
+a hatchway.
+
+The lights and voices seemed nearer now. In the dim reflected light he
+saw the sign on the door of the hatchway:
+
+ No. 2 Airlock
+ BE SURE PRESSURE GAUGE IS AT ZERO BEFORE OPENING HATCH
+
+He checked the gauge, silently spun the wheel. There was a _ping_ as the
+seals broke. He pulled the hatch open just enough to squeeze into the
+lock, then closed it behind him. Then he switched on the pumps, waiting
+impatiently until the red "all clear" signal flashed on. Then he opened
+the outside lock.
+
+Just beyond, he could see the sleek silvery lines of the _Scavenger_.
+
+It was their only chance.
+
+He took a deep breath, and jumped across the gap to the open lock of the
+_Scavenger_.
+
+
+
+
+6. The Last Run of the Scavenger
+
+
+To Greg Hunter the siege of the orbit-ship had been a nerve-wracking
+game of listening and waiting for something to happen.
+
+In the darkness of the control cabin he stretched his fingers, cramped
+from gripping the heavy Markheim stunner, and checked the corridor
+outside again. There was no sound in the darkness there, no sign of
+movement. Somewhere far below he heard metal banging on metal; minutes
+before he thought he had heard the sharp ripping sound of a stunner
+blast overhead, but he wasn't sure. Wherever the fighting was going on,
+it was not here.
+
+He shook his head as his uneasiness mounted. Why hadn't Johnny come
+back? He'd gone off to try and disable the Ranger ship leaving Greg to
+guard the control cabin. Why no sign of the marauders in the control
+cabin corridor? This should have been the first place they would head
+for, if they planned to take the ship, but there had been nothing but
+silence and darkness. Johnny had been gone near 15 minutes already. Greg
+became more uneasy.
+
+He waited. Suddenly, bitterly, he realized the hopelessness of it. Even
+if Johnny did manage to damage the Ranger ship, what difference would it
+make? They had been fools to come out here, idiots to ignore Tawney's
+warning, the three of them. Tawney had told them in so many words that
+there would be trouble, and they had come out anyway, just begging for
+it.
+
+Well, now they had what they'd begged for. Greg slammed his fist into
+his palm angrily. What had they expected? That the big company would
+step humbly aside for them, with a fortune hanging in the balance? If
+they had even begun to think it through before they started....
+
+But they hadn't, and now it was too late. They were under attack; Johnny
+was off on a fool's errand, gone too long for comfort, and Tom ... Greg
+glanced at his watch. It had been ten minutes since Tom's call. What had
+he meant by it? A plan, he said. A long chance.
+
+He couldn't shake off the cold feeling in his chest when he thought
+about Tom. What if something happened to him....
+
+Greg remembered how he had grown to resent his brother. The time when
+they were very young and Tom had been struck by the sickness, a native
+Martian virus they called it. He remembered the endless nights of
+attention given to Tom alone. From then on somehow they weren't friends
+any more. But now all that seemed to disappear and Greg only wished that
+Tom would appear down the corridor....
+
+A sound startled him. He tensed, gripping the stunner, peering into the
+darkness. Had he heard something? Or was it his own foot scraping on
+the deck plate? He held his breath, listening, and the sound came
+again, louder.
+
+Someone was moving stealthily up the corridor.
+
+Greg waited, covered by the edge of the hatchway. It might be Johnny
+returning, or maybe even Tom ... but there was no sign of recognition.
+Whoever it was was coming silently....
+
+Then a beam of light flared from a headlamp, and he saw the blue crackle
+of a stunner. He jerked back as the beam bounced off the metal walls.
+Then he was firing point blank down the corridor, his stunner on a tight
+beam, a deadly pencil of violent energy. He heard a muffled scream and a
+bulk loomed up in front of him, crashed to the deck at his feet.
+
+He fired again. Another crash, a shout, and then the sound of footsteps
+retreating. He waited, his heart pounding, but there was nothing more.
+
+The first attempt on the control cabin had failed.
+
+ * * * * *
+
+Five minutes later the second attempt began. This time there was no
+warning sound. A sudden, ear-splitting crash, a groan of tortured metal,
+and the barricaded hatchway glowed dull red. Another crash followed. The
+edge of the hatch split open, pouring acrid Murexide fumes into the
+cabin. A third explosion breached the door six inches; Greg could see
+headlamps in the corridor beyond.
+
+He fired through the crack, pressing down the stud until the stunner
+scorched his hand. Then he heard boots clanging up the other corridor.
+He pressed back against the wall, waited until the sounds were near,
+then threw open the hatch. For an instant he made a perfect target, but
+the raiders did not fire. The stunner buzzed in his hand, and once again
+the footfalls retreated.
+
+They _were_ being careful!
+
+Silence then, and blackness. Minutes passed ... five, ten.... Greg
+checked the time again. It was over twenty minutes since Tom had talked
+to him. What had happened? Whatever Tom had planned must have misfired,
+or something would have happened by now. For a moment he considered
+leaving his post and starting down the dark corridor to search ... but
+where to search? There was nothing to do but wait and hope for a
+miracle.
+
+Then suddenly the lights blazed on in the control cabin and the corridor
+outside. An attention signal buzzed in Greg's earphones. "All right,
+Hunter, it's all over," a voice grated. "You've got five minutes to get
+down to No. 3 lock. If you make us come get you, you'll get hurt."
+
+"I'll chance it," Greg snapped back. "Come on up."
+
+"We're through fooling," the voice said. "You'd better get down here.
+And bring your brother with you."
+
+"Sure," Greg said. "Start holding your breath."
+
+The contact broke for a moment, then clicked on again. This time it was
+another voice. "We've got Johnny Coombs down here," it said. "You want
+him to stay alive, you start moving. Without your stunner."
+
+Greg chewed his lip. They could be bluffing ... but they might not be.
+"I want to see Johnny," he said.
+
+On the control panel a viewscreen flickered to life. "Take a look,
+then," the voice said in his earphones.
+
+They had Johnny, all right. A burly guard was holding his good arm
+behind his back. Greg could see the speaker wires jerked loose from his
+helmet.
+
+"It's up to you," the voice said. "You've got three minutes. If you're
+not down here by then, this helmet comes off and your friend goes out
+the lock. It's quick that way, but it's not very pleasant."
+
+Johnny was shaking his head violently; the guard wrenched at his arm,
+and the miner's face twisted in pain. "Two minutes," the voice said.
+
+"Okay," Greg said. "I'm coming down."
+
+"Drop the stunner right there."
+
+He dropped the weapon onto the deck. Three steps out into the corridor,
+and two guards were there to meet him, stunners raised. They marched him
+up the ramp to the outer level corridor and around to No. 3 lock.
+
+They were waiting there with Johnny. A moment later the guards herded
+them through the lock and into the hold of the Ranger ship, stripped off
+their suits, and searched them.
+
+A big man with a heavy face and coarse black hair came into the cabin.
+He looked at Johnny and Greg and grunted. "You must be Hunter," he said
+to Greg. "Where's the other one?"
+
+"What other one?" Greg said.
+
+"Your brother. Where is he?"
+
+"How would I know?" Greg said.
+
+The man's face darkened. "You'd be smart to watch your tongue," he said.
+"We know there were three of you, we want the other one."
+
+The man turned to a guard. "What about it?"
+
+"Don't know, Doc. Nobody's reported him."
+
+"Then take a crew and search the ship. We were due back hours ago. He's
+in there somewhere."
+
+"Sure, Doc." The guard disappeared through the lock. The man called Doc
+motioned Greg and Johnny through into the main cabin.
+
+"What are you planning to do with us?" Greg demanded.
+
+"You'll find out soon enough." Doc's mouth twisted angrily.
+
+A guard burst into the cabin. "Doc, there's just nobody there! We've
+scoured the ship."
+
+"You think he just floated away in his space suit?" Doc growled. "_Find
+him._ Tawney only needs one of them, but we can't take a chance on the
+other one getting back...." He broke off, his eyes on the viewscreen.
+"Did you check those scout ships?"
+
+"No, I thought...."
+
+"Get down there and check them." Doc turned back to the viewscreen
+impatiently.
+
+Greg caught Johnny's eye, saw the big miner's worried frown. "Where is
+he?" he whispered.
+
+"I don't know. Thought you did...."
+
+"All I know is that he had some kind of scheme in mind."
+
+"Shut up," Doc said to them. "If you're smart, you'll be strapping down
+before we...." He broke off in mid sentence, listening.
+
+Quite suddenly, the Ranger ship had begun to vibrate. Somewhere, far
+away, there was the muffled rumble of engines.
+
+Doc whirled to the viewscreen. Greg and Johnny looked at the same
+instant, and Johnny groaned.
+
+Below them, the _Scavenger_'s jets were flaring. First the pale starter
+flame, then a long stream of fire, growing longer as the engines
+developed thrust.
+
+Doc slammed down a switch, roared into a speaker. "That scout
+ship ... stop it! He's trying to make a break!"
+
+Two guards appeared at the lock almost instantly, but it was too late.
+Already she was straining at her magnetic cable moorings; then the
+exhaust flared, and the little scout ship leaped away from the
+orbit-ship, moving out at a tangent to the asteroid's orbit, picking up
+speed, moving faster and faster....
+
+In toward the orbit of Mars.
+
+The man called Doc had gone pale. Now he snapped on the speaker again.
+"Frank? Stand by on missile control. He's asking for it."
+
+"Right," the voice came back. "I'm sighting in."
+
+The _Scavenger_ was moving fast now, dwindling in the viewscreen. One
+panel of the screen went telescopic to track her. "All right," Doc said.
+"Fire one and two."
+
+From both sides of the Ranger, tiny rockets flared. Like twin bullets
+the homing shells moved out, side by side, in the track of the escaping
+_Scavenger_. With a strangled cry, Greg leaped forward, but Johnny
+caught his arm.
+
+"Johnny, _Tom's on ... that thing_...."
+
+"I know. But he's got a chance."
+
+Already the homing shells were out of sight; only the twin flares were
+visible. Greg stared helplessly at the tiny light-spot of the
+_Scavenger_. At first she had been moving straight, but now she was
+dodging and twisting, her side-jets flaring at irregular intervals. The
+twin pursuit shells mimicked each change in course, drawing closer to
+her every second.
+
+And then there was a flash, so brilliant it nearly blinded them, and the
+_Scavenger_ burst apart in space. The second shell struck a fragment;
+there was another flash. Then there was nothing but a nebulous powdering
+of tiny metal fragments.
+
+The last run of the _Scavenger_ had ended.
+
+Dazed, Greg turned away from the screen, and somewhere, as if in a
+dream, he heard Doc saying, "All right, boys, strap this pair down.
+We've got a lot of work to do before we can get out of here."
+
+
+
+
+7. Prisoners
+
+
+Wherever they were planning to take them, the captors took great pains
+to make sure that their two prisoners did not escape before they were
+underway. Greg and Johnny were strapped down securely into accelleration
+cots. Two burly guards were assigned to them, and the guards were taking
+their job seriously. One of the two was watching them at all times, and
+both men held their stunners on ready.
+
+Meanwhile, under Doc's orders, the crew of the Jupiter Equilateral ship
+began a systematic looting of the orbit-ship they had disabled. Earlier
+they had merely searched the cabins and compartments. Now a steady
+stream of pressure-suited men crossed through the airlocks into the
+crippled vessel, marched back with packing cases full of tape records,
+microfilm spools, stored computer data ... anything that might
+conceivably contain information. The control cabin was literally torn
+apart. Every storage hold was ransacked.
+
+A team of six men was dispatched to the asteroid surface, searching for
+any sign of mining or prospecting activity. They came back an hour
+later, long-faced and empty handed. Doc took their reports, his scowl
+growing deeper and deeper.
+
+Finally the last of the searchers reported in. "Doc, we'd scraped it
+clean, and there's nothing there. Not one thing that we didn't check
+before."
+
+"There's _got_ to be something there," Doc said.
+
+"You tell me where else to look, and I'll do it."
+
+Doc shook his head ominously. "Tawney's not going to like it," he said.
+"There's no other place it could be...."
+
+"Well, at least we have this pair," the other said, jerking a thumb at
+Greg and Johnny. "They'll know."
+
+Doc looked at them darkly. "Yes, and they'll tell, too, or I don't know
+Tawney."
+
+Greg watched it all happening, heard the noises, saw the packing-cases
+come through the cabin, and still he could not quite believe it. He
+caught Johnny's eye, then turned away, suddenly sick. Johnny shook his
+head. "Take it easy, boy."
+
+"He didn't even have a chance," Greg said.
+
+"I know that. He must have known it too."
+
+"But why? What was he thinking of?"
+
+"Maybe he thought he could make it. Maybe he thought it was the only
+chance...."
+
+There was no other answer that Greg could see, and the ache in his chest
+was deeper.
+
+There was no way to bring Tom back now. However things had been between
+them, they could never be changed now. But he knew that as long as he
+was still breathing, somebody somehow was going to answer for that last
+desperate run of the _Scavenger_....
+
+ * * * * *
+
+It had been an excellent idea, Tom Hunter thought to himself, and it had
+worked perfectly, exactly as he had planned it ... so far. But now, as
+he clung to his precarious perch, he wondered if it had not worked out a
+little too well. The first flush of excitement that he had felt when he
+saw the _Scavenger_ blow apart in space had begun to die down now; on
+its heels came the unpleasant truth, the realization that only the easy
+part lay behind him so far. The hard part was yet to come, and if that
+were to fail....
+
+He realized, suddenly, that he was afraid. He was well enough concealed
+at the moment, clinging tightly against the outside hull of the Ranger
+ship, hidden behind the open airlock door. But soon the airlock would be
+pulled closed, and then the real test would come.
+
+Carefully, he ran through the plan again in his mind. He was certain now
+that his reasoning was right. There had been two dozen men on the raider
+ship; there had been no question, even from the start, that they would
+succeed in boarding the orbit-ship and taking its occupants prisoners.
+The Jupiter Equilateral ship had not appeared there by coincidence. They
+had come looking for something that they had not found.
+
+And the only source of information left was Roger Hunter's sons. The
+three of them together might have held the ship for hours, or even
+days ... but with engines and radios smashed, there had been no hope
+of contacting Mars for help. Ultimately, they would have been taken.
+
+As he had crouched in the dark storage hold in the orbit-ship, Tom had
+realized this. He had also realized that, once captured, they would
+never have been freed and allowed to return to Mars.
+
+If the three of them were taken, they were finished. But what if only
+two were taken? He had pushed it aside as a foolish idea, at first. The
+boarding party would never rest until they had accounted for all three.
+They wouldn't dare go back to their headquarters leaving one live man
+behind to tell the story....
+
+Unless they thought the third man was dead. If they were sure of
+that ... _certain_ of it ... they would not hesitate to take the
+remaining two away. And if, by chance, the third man wasn't as dead as
+they thought he was, and could find a way to follow them home, there
+might still be a chance to free the other two.
+
+It was then that he thought of the _Scavenger_, and knew that he had
+found a way.
+
+In the cabin of the little scout ship he had worked swiftly, fearful
+that at any minute one of the marauders might come aboard to search it.
+Tom was no rocket pilot, but he did know that the count-down was
+automatic, and that every ship could run on an autopilot, as a drone,
+following a prescribed course until it ran out of fuel. Even the
+shell-evasion mechanism could be set on automatic....
+
+Quickly he set the autopilot, plotted a simple high school math course
+for the ship, a course the Ranger ship would be certain to see, and to
+fire upon. He set the count-down clock to give himself plenty of time
+for the next step.
+
+Both the airlock to the _Scavenger_ and to the orbit-ship worked on
+electric motors. The _Scavenger_ was grappled to the orbit-ship's hull
+by magnetic cables. Tom dug into the ship's repair locker, found the
+wires and fuses that he needed, and swiftly started to work.
+
+It was an ingenious device. The inner airlock door in the orbit-ship was
+triggered to a fuse. He had left it ajar; the moment it was closed, by
+anyone intending to board the _Scavenger_, the fuse would burn, a
+circuit would open, and the little ship's autopilot would go on active.
+The ship would blast away from its moorings, head out toward Mars....
+
+And the fireworks would begin. All that he would have to worry about
+then would be getting himself aboard the Ranger ship without being
+detected.
+
+Which was almost impossible. But he knew there was a way. There was one
+place no one would think to look for him, if he could manage to keep out
+of range of the viewscreen lenses ... the outer hull of the ship. If he
+could clamp himself to the hull, somehow, and manage to cling there
+during blastoff, he could follow Greg and Johnny right home.
+
+He checked the fuse on the airlock once again to make certain it would
+work. Then he waited, hidden behind the little scout ship's hull,
+until the orbit-ship swung around into shadow. He checked his suit
+dials ... oxygen for twenty-two hours, heater pack fully charged,
+soda-ash only half saturated ... it would do. Above him he could see the
+rear jets of the Ranger. He swung out onto the orbit-ship's hull, and
+began crawling up toward the enemy ship.
+
+It was slow going. Every pressure suit had magnetic boots and hand-pads
+to enable crewmen to go outside and make repairs on the hull of a ship
+in transit. Tom clung, and moved, and clung again, trying to reach the
+protecting hull of the Ranger before the orbit-ship swung him around to
+the sun-side again....
+
+He couldn't move fast enough. He saw the line of sunlight coming around
+the ship as it swung full into the sun. He froze, crouching motionless.
+If somebody on the Ranger spotted him now, it was all over. He was
+exposed like a lizard on a rock. He waited, hardly daring to breathe, as
+the ship spun ponderously around, carrying him into shadow again.
+
+And nothing happened. He started crawling upward again, reached up to
+grab the mooring cable, and swung himself across to the hull of the
+Ranger. The airlock hung open; he scuttled behind it, clinging to the
+hull in its shadow just as Greg and Johnny were herded across by the
+Jupiter Equilateral guards.
+
+Then he waited. There was no sound, no sign of life. After a while the
+Ranger's inner lock opened, and a group of men hurried across to the
+orbit-ship. Probably a searching party, Tom thought. Soon the men came
+back, then returned to the orbit-ship. After another minute, he felt the
+vibration of the _Scavenger_'s motors, and he knew that his snare had
+been triggered.
+
+He saw the little ship break free and streak out in its curving
+trajectory. He saw the homing shells burst from the Ranger's tubes. The
+_Scavenger_ vanished from his range of vision, but moments later he saw
+the sudden flare of light reflected against the hull of the orbit-ship,
+and he knew his plan had worked, but the ordeal lay ahead.
+
+And at the end of it, he might really be a dead man.
+
+ * * * * *
+
+Hours later, the last group of looters left the orbit-ship, and the
+airlock to the Ranger clanged shut. Tom heard the sucking sound of the
+air-tight seals, then silence. The orbit-ship was empty, its insides
+gutted, its engines no longer operable. The Ranger hung like a long
+splinter of silver alongside her hull, poised and ready to move on.
+
+He knew that the time had come. Very soon the blastoff and the
+accelleration would begin. He had a few moments to find a position of
+safety, no more.
+
+Quickly, he began scrambling toward the rear of the Ranger's hull,
+hugging the metal sides, moving sideways like a crab. Ahead, he knew,
+the viewscreen lenses would be active; if one of them picked him up, it
+would be quite a jolt to the men inside the ship ... but it would be the
+end of his free ride.
+
+But the major peril was the blastoff. Once the engines cut off, the ship
+would be in free fall. Then he could cling easily to the hull, walk all
+over it if he chose to, with the aid of his boots and hand-pads. But
+unless he found a way to anchor himself firmly to the hull during
+blastoff, he could be flung off like a pebble.
+
+He heard a whirring sound, and saw the magnetic mooring cables jerk. The
+ship was preparing for blastoff. Automatic motors were drawing the
+cables and grappling plates into the hull. Moving quickly, Tom reached
+the rear cable. Here was his anchor, something to hold him tight to the
+hull! With one hand he loosened the web belt of his suit, looped it over
+a corner of the grappling plate as it pulled in to the hull.
+
+The plate pulled tight against the belt. Each plate fit into a shallow
+excavation in the hull, fitting so tightly that the plates were all but
+invisible when they were in place. Tom felt himself pulled in tightly as
+the plate gripped the belt against the metal, and the whirring of the
+motor stopped.
+
+For an instant it looked like the answer. The belt was wedged
+tight ... he couldn't possibly pull loose without ripping the nylon
+webbing of the belt. But a moment later the motor started whirring again.
+The plate pushed out from the hull a few inches, then started back, again
+pulling in the belt....
+
+A good idea that just wouldn't work. The automatic machinery on a
+spaceship was built to perfection; nothing could be permitted to
+half-work. Tom realized what was happening. Unless the plate fit
+perfectly in its place, the cable motor could not shut off, and
+presently an alarm signal would start flashing on the control panel.
+
+He pulled the belt loose, reluctantly. He would have to count on his
+boots and his hand-pads alone.
+
+He searched the rear hull, looking for some break in the polished metal
+that might serve as a toehold. To the rear the fins flared out,
+supported by heavy struts. He made his way back, crouching close to the
+hull, and straddled one of the struts. He jammed his magnetic boots down
+against the hull, and wrapped his arms around the strut with all his
+strength.
+
+Clinging there, he waited.
+
+It wasn't a good position. The metal of the strut was polished and
+slick, but it was better than trying to cling to the open hull. He
+tensed now, not daring to relax for fear that the blastoff accelleration
+would slam him when he was unprepared.
+
+Deep in the ship, the engines began to rumble. He felt it rather
+than heard it, a low-pitched vibration that grew stronger and stronger.
+The Ranger would not need a great thrust to move away from the
+orbit-ship ... but if they were in a hurry, they might start out at
+nearly Mars-escape....
+
+The jets flared, and something slammed him down against the fin strut.
+The Ranger moved out, its engines roaring, accellerating hard. Tom felt
+as though he had been hit by a ton of rock. The strut seemed to press in
+against his chest; he could not breathe. His hands were sliding, and he
+felt the pull on his boots. He tightened his grip desperately. This was
+it. He had to hang on, _had_ to hang on....
+
+He saw his boot on the hull surface, sliding slowly, creeping back and
+stretching his leg, suddenly it broke loose; he lurched to one side, and
+the other boot began sliding. There was a terrible ache in his arms, as
+though some malignant giant were tearing at him, trying to wrench him
+loose as he fought for his hold.
+
+There was one black instant when he knew he could not hold on another
+second. He could see the blue flame of the jet streaming behind him, the
+cold blackness of space beyond that. It had been a fool's idea, he
+thought in despair, a million-to-one shot that he had taken, and
+lost....
+
+And then the pressure stopped. His boots clanged down on the hull, and
+he almost lost his hand-grip. He stretched an arm, shook himself, took a
+great painful breath, and then clung to the strut, almost sobbing,
+hardly daring to move.
+
+The ordeal was over. Somewhere, far ahead, an orbit-ship was waiting for
+the Ranger to return. He would have to be ready for the braking thrust
+and the side-maneuvering thrusts, but he would manage to hold on.
+Crouching against the fin, he would be invisible to viewers on the
+orbit-ship ... and who would be looking for a man clinging to the
+outside of a scout-ship?
+
+Tom sighed, and waited. Jupiter Equilateral would have its prisoners,
+all right. He wished now that he had not discarded the stunner, but
+those extra pounds might have made the difference between life and death
+during the blastoff. And at least he was not completely unarmed. He
+still had Dad's revolver at his side.
+
+He smiled to himself. The pirates would have their prisoners,
+indeed ... but they would have one factor to deal with that they
+had not counted on.
+
+ * * * * *
+
+For Greg it was a bitter, lonely trip.
+
+After ten hours they saw the huge Jupiter Equilateral orbit-ship looming
+up in the viewscreen like a minor planet. Skilfully Doc maneuvered the
+ship into the launching rack. The guards unstrapped the prisoners, and
+handed them pressure suits.
+
+Moments later they were in a section in crews' quarters where they
+stripped off their suits. This orbit-ship was much larger than Roger
+Hunter's; the gravity was almost Mars-normal, and it was comforting just
+to stretch and relax their cramped muscles.
+
+As long as they didn't think of what was ahead.
+
+Finally Johnny grinned and slapped Greg's shoulder. "Cheer up," he said.
+"We'll be honored guests for a while, you can bet on that."
+
+"For a while," Greg said bitterly.
+
+Just then the hatchway opened. "Well, who do we have here?" a familiar
+voice said. "Returning a call, you might say. And maybe this time you'll
+be ready for a bit of bargaining."
+
+They turned to see the heavy face and angry eyes of Merrill Tawney.
+
+
+
+
+8. The Scavengers of Space
+
+
+The casual observer might have been fooled. Tawney's guard was down only
+for an instant; then the expression of cold fury and determination on
+his face dropped away as though the shutter of a camera had clicked, and
+he was all smiles and affability. They were honored guests here, one
+would have thought, and this pudgy agent of the Jupiter Equilateral
+combine was their genial host, anxious for their welfare, eager to do
+anything he could for their comfort....
+
+They were amazed by the luxuriousness of the ship. For the next few
+hours they received the best treatment, sumptuous accommodations,
+excellent food.
+
+They were finishing their second cup of coffee when Tawney asked,
+"Feeling better, gentlemen?"
+
+"You do things in a big way," Johnny said. "This is real coffee, made
+from grounds. Must have cost a fortune to ship it out here."
+
+Tawney spread his hands. "We keep it for special occasions. Like when we
+have special visitors."
+
+"Even when the visits aren't voluntary," Greg added sourly.
+
+"We have to be realistic," Tawney said. "Would you have come if we
+invited you? Of course not. You gentlemen chose to come out to the Belt
+in spite of my warnings. You thus made things very awkward for us, upset
+certain of our plans." He looked at Greg. "We don't ordinarily allow
+people to upset our plans, but now we find that we're forced to include
+you in our plans, whether you happen to like the idea or not."
+
+"You're doing a lot of talking," Greg said. "Why don't you come to the
+point?"
+
+Tawney was no longer smiling. "We happen to know that your father struck
+a rich lode on one of his claims."
+
+"That's interesting," Greg said. "Did Dad tell you that?"
+
+"He didn't have to. A man can't keep a secret like that, not for very
+long. Ask your friend here, if you don't believe me. And we make it our
+business to know what's going on out here. We have to, in order to
+survive."
+
+"Well, suppose you heard right. The law says that what a man finds on
+his own claim is his."
+
+"Certainly," Tawney said. "Nobody would think of claim-jumping, these
+days. But when a man happens to die before he can bring in his bonanza,
+then it's a question of who gets there first, wouldn't you think?"
+
+"Not when the man is murdered," Greg said hotly, "not by a long shot."
+
+"But you can't prove that your father was murdered."
+
+"If I could, I wouldn't be here."
+
+"Then I think we'll stick to the law," Tawney said, "and call it an
+accident."
+
+"And what about my brother? Was that an accident?"
+
+"Ah, yes, your brother." Tawney's eyes hardened. "Quite a different
+matter, that. Sometimes Doc tends to be over-zealous in carrying out his
+assigned duties. I can assure you that he has been ... disciplined."
+
+"That's not going to help Tom very much."
+
+"Unfortunately not," Tawney said. "Your brother made a very foolish
+move, under the circumstances. But from a practical point of view,
+perhaps it's not entirely a tragedy."
+
+"What do you mean by that?"
+
+"From what I've heard," Tawney said, "you didn't have much use for your
+twin brother. And now you certainly won't have to share your father's
+legacy...."
+
+It was too much. With a roar Greg swung at the little fat man. The blow
+caught Tawney full in the jaw, jerked his head back. Greg threw his
+shoulder into a hard left, slamming Tawney back against the wall. The
+guard charged across the room, dragging them apart as Tawney blubbered
+and tried to cover his face. Greg dug his elbow into the guard's
+stomach, twisted away and started for Tawney again. Then Johnny caught
+his arm and spun him around. "Stop it," he snapped. "Use your head,
+boy...."
+
+Greg stopped, glaring at Tawney and gasping for breath. The company man
+picked himself up, rubbing his hand across his mouth. For a moment he
+trembled with rage. Then he gripped the table with one hand, forcibly
+regaining his control. He even managed a sickly smile. "Just like your
+father," he said, "too hot-headed for your own good. But we'll let it
+pass. I brought you here to make you an offer, a very generous offer,
+and I'll still make it. I'm a businessman, when I want something I want
+I bargain for it. If I have to share a profit to get it, I share the
+profit. All right ... you know where your father's strike is. We want
+it. We can't find it, so you've got us over a barrel. We're ready to
+bargain."
+
+Greg started forward. "I wouldn't bargain with you for...."
+
+"Shut up, Greg," Johnny said.
+
+Greg stared at him. The big miner's voice had cracked like a whip; now
+he was drawing Merrill Tawney aside, speaking rapidly into his ear.
+Tawney listened, shot a venomous glance across at Greg, and finally
+nodded. "All right," he said, "but I can't wait forever...."
+
+"You won't have to."
+
+Tawney turned to the guard. "You have your orders," he said. "They're to
+have these quarters, and the freedom of the ship, except for the outer
+level. They're not to be harmed, and they're not to be out of your sight
+except when they're locked in here. Is that clear?"
+
+The guard nodded. Tawney looked at Johnny, and started for the door,
+still rubbing his jaw. "We'll talk again later," he said, and then he
+was gone.
+
+When the guard had left, and the lock buzzed in the door, Johnny looked
+at Greg and shook his head sadly. "You just about fixed things, boy, you
+really did. You've got to use your head if you want to stay alive a
+while, that's all. Look, there isn't going to be any bargaining with
+Tawney, he just doesn't work that way. It's heads he wins, tails we
+lose. Once he has what he wants we won't last six minutes. All right,
+then there's just one thing that can keep us alive ... stalling him.
+We've got to make him think you'll give in if he plays his cards right."
+
+Greg was silent for a minute. "I hadn't thought of it that way."
+
+"And we've got to use the time we have to find some way to break for
+it." Johnny stood up, staring around the luxurious lounge. "If you want
+my opinion, it's going to take some pretty fancy footwork to get out of
+here with our skins."
+
+ * * * * *
+
+True to his word, Tawney had given them the freedom of the ship. Greg
+and Johnny discovered that their guard was also an excellent guide. All
+day he had been leading them through the ship, chatting and answering
+their questions about asteroid mining, until they almost forgot that
+they were really prisoners here. And the guard's obvious pride in the
+scope and skill of his company's mining operations was strangely
+infectious.
+
+Watching the Jupiter Equilateral ship in operation, Greg felt his heart
+sink. Here was a huge, powerful organization, with all the equipment and
+men and know-how they could ever need. How could one man, or two or
+three in a team, hope to compete with them? For the independent miner,
+the only hope was the Big Strike, the single lode that could make him
+rich. He might work all his life without finding it, and then stumble
+upon it by sheer chance....
+
+But if he couldn't keep it when he found it, then what? What if the
+great mining company became so strong that they could be their own law
+in the Belt? What if they grew strong enough and powerful enough to
+challenge the United Nations on Mars itself, and gain control of the
+entire mining industry? What chance would the independent miner have
+then?
+
+It was a frightening picture. Suddenly something began to make sense to
+Greg; he realized something about his father that he had never known
+before.
+
+Roger Hunter had been a miner, yes. But he had been something else too,
+something far more important than just a miner.
+
+Roger Hunter had been a fighter, fighting to the end for something he
+believed in....
+
+Tawney interrupted Greg's thought.
+
+"Quite an operation," he said.
+
+Greg looked at him. "So I see."
+
+"And very efficient, too. Our men have everything they need to work
+with. We can mine at far less cost than anyone else."
+
+"But you still can't stand the idea of independent miners working the
+Belt," Greg said.
+
+Tawney's eyebrows went up. "But why not? There's lots of room out here.
+Our operation with Jupiter Equilateral is no different from an
+independent miner's operation. We aren't different kinds of people."
+Tawney smiled. "When you get right down to it, we're both exactly the
+same thing ... scavengers in space, vultures picking over the dead
+remains to see what we can find. We come out to the asteroids, and we
+bring back what we want and leave the rest behind. And it doesn't matter
+whether we've got one ship working or four hundred ... we're still just
+scavengers."
+
+"With just one difference," Greg said, turning away from the viewscreen.
+
+"Difference?"
+
+Greg nodded. "Even vultures don't kill their own," he said.
+
+ * * * * *
+
+Later, when they were alone in their quarters again, Greg and Johnny
+stared at each other gloomily.
+
+"Didn't you see _anything_ that might help us?" Greg said.
+
+"Not much. For an orbit-ship, this place is a fortress. I got a good
+look at that scout ship coming in ... it was armed to the teeth.
+Probably they all are. And they're keeping a guard now at every
+airlock."
+
+"So we're sewed up tight," Greg said.
+
+"Looks that way. They've got us, boy, and I think Tawney's patience is
+wearing thin, too. We're either going to have to produce or else."
+
+"But what can we do?"
+
+"Start bluffing."
+
+"It seems to me we're just about bluffed out."
+
+"I mean talk business," Johnny said. "Tell Tawney what he wants to
+know."
+
+"When we don't know any more than he does? How?"
+
+Johnny Coombs scratched his jaw. "I've been thinking about that," he
+said slowly, "and I wonder if we don't know a whole lot more than we
+think we do."
+
+"Like what?" Greg said.
+
+"We've all been looking for the same thing ... a Big Strike, a bonanza
+lode. Tawney's men have raked over every one of your Dad's claims, and
+they haven't turned up a thing." Johnny looked at Greg. "Makes you
+wonder a little, doesn't it? Your Dad was smart, but he was no magician.
+And how does a man go about hiding something like a vein of ore?"
+
+"I don't know," Greg said. "It doesn't seem possible."
+
+"It isn't possible," Johnny said flatly. "There's only one possible
+explanation, and we've been missing it all along. Whatever he found, _it
+wasn't an ore strike_. It was something else, something far different
+from anything we've been thinking of."
+
+Greg stared at him. "But if it wasn't an ore strike, what was it?"
+
+"I don't know," Johnny said. "But I'm sure of one thing ... it was
+something important enough that he was ready to die before he'd reveal
+it. And that means it was important enough that Tawney won't dare kill
+us until he finds out what it was."
+
+
+
+
+9. The Invisible Man
+
+
+Crouching back into the shadow, Tom Hunter waited as the heavy footsteps
+moved up the corridor, then back down, then up and down again. He peered
+around the corner for a moment, looking quickly up and down the curving
+corridor. The guard was twenty yards away, moving toward him in a slow
+measured pace. Tom jerked his head back, then peered out again as the
+footsteps receded.
+
+The guard was a big man, with a heavy-duty stunner resting in the crook
+of his elbow. He paused, scratched himself, and resumed his pacing. Tom
+waited, hoping that something might distract the big man, but he moved
+stolidly back and forth, not too alert, but far too alert to risk
+breaking out into the main corridor.
+
+Tom moved back into the darkened corridor where he was standing, trying
+to decide what to do. It was a side corridor, and a blind alley; it
+ended in a large hatchway marked HYDROPONICS, and there were no
+branching corridors. If he were discovered here, there would be no place
+to hide.
+
+But he knew that he could never hope to accomplish his purpose here....
+
+A hatch clanged open, and there were more footsteps down the main
+corridor as a change of guards hurried by. There was a rumble of voices,
+and Tom listened to catch the words.
+
+"... don't care what you think, the boss says tighten it up...."
+
+"But they got them locked in...."
+
+"So tell it to the boss. We're supposed to check every compartment in
+the section every hour. Now get moving...."
+
+The footsteps moved up and down the corridor then, and Tom heard hatches
+clanging open. If they sent a light down this spur ... he turned to the
+hatch, spun the big wheel on the door, and slipped inside just as the
+footsteps came closer.
+
+The stench inside was almost overpowering. The big, darkened room was
+extremely warm, the air damp with vapor. The plastic-coated walls
+streamed with moisture. Against the walls Tom could see the great
+hydroponic vats that held the yeast and algae cultures that fed the crew
+of the ship. Water was splashing in one of the vats, and there was a
+gurgling sound as nutrient broth drained out, to be replaced with
+fresh.
+
+He moved swiftly across the compartment, into a darkened area behind the
+rows of vats, and crouched down. He heard footsteps, and the ring of
+metal as the hatchway came open. One of the guards walked in, peered
+into the gloom, wrinkled his nose, and walked out again, closing the
+hatchway behind him.
+
+It would do for a while ... if he didn't suffocate ... but if this ship
+was organized like smaller ones, it would be a blind alley. Modern
+hydroponic tanks did not require much servicing, once the cultures were
+growing; the broth was drained automatically and sluiced through a
+series of pipes to the rendering plant where the yeasts could be
+flavored and pressed into surrogate steaks and other items for spaceship
+cuisine. There would be no other entrances, no way to leave except the
+way he had come in.
+
+And with the guards on duty, that was out of the question. He waited,
+listening, as the check-down continued in nearby compartments. Then
+silence fell again. The heavy yeast aroma had grown more and more
+oppressive; now suddenly a fan went on with a whir, and a cool draft of
+freshened reprocessed air poured down from the ventilator shaft above
+his head.
+
+Getting into the orbit-ship had been easier than he had hoped. In the
+excitement as the new prisoners were brought aboard, security measures
+had been lax. No one had expected a third visitor; in consequence, no
+one looked for one. Huge as it was, the Jupiter Equilateral ship had
+never been planned as a prison, and it had taken time to stake out the
+guards in a security system that was at all effective. In addition,
+every man who served as a guard had been taken from duty somewhere else
+on the ship.
+
+So there had been no guard at the airlock in the first few moments after
+the prisoners were taken off the Ranger ship. Tom had waited until the
+ship was moored, clinging to the fin strut. He watched Greg and Johnny
+taken through the lock, and soon the last of the crew had crossed over
+after securing the ship. Presently the orbit-ship airlock had gone dark,
+and only then had he ventured from his place of concealment, creeping
+along the dark hull of the Ranger ship and leaping across to the
+airlock.
+
+A momentary risk, then, as he opened the lock. In the control room, he
+knew, a signal light would blink on a panel as the lock was opened. Tom
+moved as quickly as he could, hoping that in the excitement of the new
+visitors, the signal would go unnoticed ... or if spotted, that the
+spotter would assume it was only a crewman making a final trip across to
+the Ranger ship.
+
+But once inside, he began to realize the magnitude of his problem. This
+was not a tiny independent orbit-ship with a few corridors and
+compartments. This was a huge ship, a vast complex of corridors and
+compartments and holds. There was probably a crew of a thousand men on
+this ship ... and there was no sign where Greg and Johnny might have
+been taken.
+
+He moved forward, trying to keep to side corridors and darkened areas.
+In the airlock he had wrapped up his pressure suit and stored it on a
+rack; no one would notice it there, and it might be handy later. He had
+strapped his father's gun case to his side, some comfort, but a small
+one.
+
+Now, crouching behind the yeast vat, he lifted out the gun, hefted it
+idly in his hand. It was a weapon, at least. He was not well acquainted
+with guns, and in the shadowy light it seemed to him that this one
+looked odd for a revolver; it even felt wrong, out of balance in his
+hand. He slipped it back in the case. After all, it had been fitted to
+Dad's hand, not his. And Johnny or Greg would know how to use it better
+than he would.
+
+If he could find them. But to do that, he would have to search the ship.
+He would have to move about, he couldn't just wait in a storage hold.
+And with all the guards that were posted, he would certainly stumble
+into one of them sooner or later if he tried leaving this spot....
+
+He shook his head, and started for the hatch. He would have to chance
+it. There was no way to tell how much time he had, but it was a sure bet
+that he didn't have very long.
+
+In the spur corridor again, he waited until the guard's footsteps were
+muffled and distant. Then he darted out into the main corridor, moving
+swiftly and silently away from the guard. At the first hatchway he
+ducked inside, waited in the darkness, panting....
+
+The guard had stopped walking. Then his footsteps resumed, but more
+quickly, coming down the corridor. He stopped, almost outside the
+hatchway door. "Funny," Tom heard him mutter. "I'd have sworn...."
+
+Tom held his breath, waiting. This was a storage hold, but he didn't
+dare to move, even to take cover. The guard stood motionless for a
+moment, then grunted, and resumed his slow pacing.
+
+When he had moved away Tom caught his breath in huge gasps, his heart
+beating in his throat. It was no use, he thought in despair. Once or
+twice he might get away with it, but sooner or later a guard would be
+alert enough to investigate an obscure noise, a flicker of movement in
+the corner of his eye....
+
+There had to be another way. His eye probed the storage hold,
+hopelessly, and then stopped on a metal grill in the wall.
+
+For a moment, he didn't recognize what it was. Then there was a
+_whoosh-whoosh-whoosh_ as a fan went on, and he felt cool air against
+his cheek. He held out his hand to the grill, found the air coming from
+there.
+
+A ventilation shaft. Every space craft had to have reconditioning units
+for the air inside the ship; the men inside needed a constant supply of
+fresh oxygen, but even more, without pumps to move the air in each
+compartment they would soon suffocate from the accumulation of carbon
+dioxide in the air they breathed out, or bake from the heat their bodies
+radiated. On the other hand, the yeasts and algae required carbon
+dioxide and yielded copious amounts of oxygen as they grew.
+
+In Roger Hunter's little orbit-ship the ventilation shafts were small, a
+loose network of foot-square ducts leading from the central pumps and
+air-reconditioning units to every compartment in the ship. But in a ship
+of this size....
+
+The grill was over a yard wide, four feet tall. It started about
+shoulder height and ran up to the overhead. The ducts would network the
+ship, opening into every compartment, and no one would ever open them
+unless something went wrong.
+
+And then he was laughing out loud, working the grill out of the slots
+that held it to the wall, trying to make his hands work in his
+excitement.
+
+He knew he had found his answer.
+
+The grill came loose, lifted down in a piece. He stopped short as
+footsteps approached in the corridor, paused, and went on. Then he
+peered into the black gaping hole behind the grill. It was big enough
+for a man to crawl in. He shinned up into the hole, and pulled the grill
+back into its slot behind him.
+
+Somewhere far away he heard a throbbing of giant pumps. There was a rush
+of cool fresh air past his cheek, cold when it contacted the sweat
+pouring down his forehead. He could not quite stand up, but there was
+plenty of room for him to crouch and move.
+
+Ahead of him was a black tunnel, broken only by a patch of light coming
+through the grill that opened into the next compartment. He started into
+the blackness, his heart racing.
+
+Somewhere in the ship Johnny Coombs and Greg Hunter were
+prisoners ... but now, Tom knew, there was a way to escape.
+
+ * * * * *
+
+It was a completely different world, a world within a world, a world of
+darkness and silence, of a thousand curving and intersecting tunnels,
+some large, some small. For hours it seemed to him that he had been
+wandering through a tomb, moving through the corridors of a dead ship,
+the lone surviving crewman. There was some contact with the other world,
+of course, the world of the spaceship outside ... each compartment had
+its metal grill, and he passed many of them. But there were like doors
+that only he knew existed. He met no one in _these_ corridors, there was
+no danger of sudden discovery and arrest in these dark alleys....
+
+His boots had made too much noise as he started out, so he had slipped
+them off, hanging them from his belt and moving on in his stocking feet.
+As he went from duct to duct, he had an almost ridiculous feeling of
+freedom and power. In every sense, he was an invisible man. Not one soul
+on this great ship knew he was here, or even suspected. He had the run
+of the ship, complete freedom to go wherever he chose. He could move
+from compartment to compartment as silently and invisibly as if he had
+no substance at all.
+
+ * * * * *
+
+He knew the first job was to learn the pattern of the ducts, and
+orientation was a problem. He had heard stories of men getting lost in
+the deep underground mining tunnels on Mars, wandering in circles for
+days until their food gave out and they starved. And there was that
+hazard here, for every duct looked like every other one.
+
+But there was a difference here, because the ducts curved just as the
+main ship's corridors did. He could always identify the center of the
+ship by the force of false gravity pulling the other way. Furthermore,
+as the ducts drew closer to the pumps and reconditioning units, they
+opened into larger vents, and the noise of the pumps thundered in his
+ears. After an hour of exploration, Tom was certain that from any place
+in the ship he could at least find his way to the outer layer, and from
+there to one of the scout-ship airlocks.
+
+Finding Greg and Johnny was quite a different matter.
+
+He could not see enough through the compartment grills to identify just
+what the compartments were; he was forced to rely on what he could hear.
+The engine rooms were easily identified. In one area he heard the
+banging of pots and pans, the steaming of kettles ... obviously the
+galley. He found the control area. He could hear the clatter of typing
+instruments, the _click-click-click_ of the computers working out the
+orbits and trajectories for the scout-ships as they moved out from the
+orbit-ship or came back in. In another compartment he heard a dispatcher
+chattering his own special code-language into a microphone in a
+low-pitched voice. He passed another grill, and then stopped short as a
+familiar voice drifted through.
+
+Merrill Tawney's voice.
+
+Tom hugged the grill, straining to catch the words. The company man
+sounded angry; the man he was talking to sounded even angrier. "I can't
+help what you want or don't want, Merrill, I can only report what we've
+found, and that's nothing at all. Every one of those claims has been
+searched twice over. Doc and his boys went over them, and we didn't find
+anything they missed. I think you're barking up the wrong tree."
+
+"There's _got_ to be something," Tawney said, his voice tight with
+anger. "Hunter couldn't have taken anything away from there, he didn't
+have a chance to. You read the reports..."
+
+"I know," the other said wearily, "I know what the reports said."
+
+"Then what he found is still there. There's no other possibility,"
+Tawney said.
+
+"We went over that rock with a microscope. We blew it to shreds. Assay
+has gone through the fragments literally piece by piece. They found low
+grade iron, a trace of nickel, a little tin, and lots of granite. If we
+never found anything richer than that, we'd have been out of business
+ten years ago."
+
+There was a long silence. Tom pressed closer to the grill. Then he heard
+Tawney slam his fist into his palm. "You know what Roger Hunter's doing,
+don't you?" he said. "He's making fools of us, that's what! The man's
+dead, and he's making us look like idiots. If we hadn't been so sure we
+had the lode spotted ..." He broke off. "Well, that's done, we can't
+undo it. But this brat of his...."
+
+"Any luck there?"
+
+"Not a word. He's playing coy."
+
+"Maybe he doesn't know anything. Doc made a bad mistake when he blasted
+the other one ... suppose _he_ was the only one that knew."
+
+"All right, it was a mistake," Tawney snapped. "What was he supposed to
+do, let him get back to Mars? We've got a good front there, but it's not
+that good. If the United Nations gets a toehold out here, the whole Belt
+will go into their pocket, you realize that. They're waiting for us to
+make one slip." He paused, and Tom heard him pacing the compartment.
+"But I think we've got our boy. This one knows. We've been spoiling him
+so far, that's all. Well, now we start digging. When I get through with
+him, he'll be begging us to let him tell. You just watch me, as soon as
+the okay comes through...."
+
+Tom drew back from the grill, moving on in the darkness. So far he had
+not rushed his exploration ... there was a chance to use the ducts for
+escape, he wanted to know them well. But now he knew the hour was
+getting late. So far Greg and Johnny had been stalling Tawney ... but
+Tawney was getting impatient.
+
+He moved quickly and he thought again of what Tawney had said. Tawney
+was right about one thing ... there was no way that Dad could have
+hidden a Big Strike so nobody could find it. It had to be there....
+
+And yet it wasn't. He and Greg hadn't found it. Tawney's men hadn't
+found it, either. Why not? There must be a reason.
+
+But he could not put his finger on it.
+
+Half an hour later he was seriously worried. Half the compartments in
+the area were deserted, the men leaving for the cafeteria. The thought
+reminded Tom how hungry he was, and thirsty. His small emergency ration
+kit was empty. He toyed with the thought of sneaking into a food storage
+compartment, then thrust it out of his mind as too risky. He had to find
+Greg and Johnny before anything.
+
+He passed a grill, and heard a murmur of voices; something in the deep
+bass rumble caught his ear, and he stopped, listened.
+
+The voices stopped also.
+
+He waited for them to begin, pressing against the grill. Johnny Coombs
+was not the only man with a deep bass voice, he might have been
+mistaken. He listened, but there was no sound. He heard the whir of a
+fan begin, still no sound, not even footsteps.
+
+And then it happened, so fast he was taken completely off guard. The
+grill suddenly gave way, pitching him forward into the compartment.
+Something struck him behind the ear as he fell; there was a grunt, a
+sharp command, and he was pinned to the floor in the semi-darkness of
+the compartment.
+
+Then he heard a gasp, and he opened his eyes. He was staring into his
+brother's startled face. Greg was pinning his shoulders to the carpeted
+deck, and behind him Johnny Coombs had a fist raised....
+
+But they had stopped in mid-air, like a tableau of puppets. Greg gaped,
+his jaw falling open, and Tom heard himself saying, "What are you trying
+to do, kill a guy? Seems to me one time is enough."
+
+He had found them.
+
+
+
+
+10. The Trigger
+
+
+In the first instance of astonishment they were speechless. Later, Tom
+said it was the first time in his life that he had ever seen Greg
+totally without words; his brother jumped back, as if he had seen a
+ghost, and his mouth worked, but no sounds came out.
+
+"Don't worry, it's me all right," Tom said, "and I'm mighty hungry."
+
+Greg and Johnny stared at the black hole behind the grill ... and then
+Greg was pumelling him, pounding him on the back, so excited he couldn't
+get a sentence out, and Johnny was hovering over them, incredulous but
+forced to believe his eyes, like a father overwhelmed by the impossible
+behavior of a pair of unpredictable children. It was a jubilant reunion.
+They broke open the cabinets and refrigerator in the back of the lounge
+and pulled out surro-ham and rolls, while Johnny got some coffee going.
+Tom was so famished he could hardly wait to make sandwiches of the ham.
+He ate it as fast as he got it.
+
+But finally he slowed up, got his mouth empty enough to talk. "All
+right, let's have the story," Greg said, still looking as though he
+couldn't believe his eyes. "The last we saw, you were blown into atoms
+out there in that _Scavenger_ ... you've got some nerve turning up now
+and scaring us half out of our skins...."
+
+"You want me to go back in my hole?"
+
+"Just sit still and talk!"
+
+Tom told them, then, starting from the beginning.
+
+Through it all Greg stared in admiration. "We've got a genius among us,
+that's all," he said finally. "And I always thought you were the timid
+one...."
+
+"But what else could I do?" Tom said. "You know what they say about
+grabbing a tiger by the tail ... once you get hold, you've got to hold
+on."
+
+"Okay," Greg said, "but the next time I make a crack about your retiring
+nature, remind me to stick my foot in my mouth."
+
+"I'll do it for him," Johnny Coombs rumbled.
+
+Tom nodded toward the open grill. "The only thing I don't see is how you
+knew I was back there."
+
+Johnny grinned. "We were busy taking down the grill when you came
+along. We'd found three microphones in this place, and figured they
+might have one behind the grill. And then we heard somebody breathing
+back there ... we thought they'd posted a guard back there, just to snoop
+us."
+
+"Well, I'm glad you didn't hit him any harder...."
+
+Johnny started to say something, then stopped, cocked his head toward
+the door. There were footsteps in the corridor outside; they came
+closer, stopped by the door. "Quick," Johnny hissed, "back inside!"
+
+There was no time to look for other concealment. Tom leaped across the
+room, jumped up into the shaft again, and Greg slammed the grate up into
+place just as the hatchway door swung open.
+
+Merrill Tawney walked into the room, with two burly guards behind him.
+
+ * * * * *
+
+For the first few seconds, Greg was certain that they were lost. He
+stood with his back to the ventilator grill, frozen in his tracks as the
+fat little company man came in the room. He tried to keep his face
+blank, but he knew he wasn't succeeding. He saw the puzzled frown form
+on Tawney's face.
+
+The company man motioned the guards into the room, peered suspiciously
+at Greg and Johnny. "Am I interrupting something, by any chance?"
+
+"Nothing at all," Johnny blurted. "We were just talking."
+
+"Talking." Tawney repeated the word as if it were some strange language
+he didn't quite understand. He looked at the guard. "Let's just check
+them."
+
+While one guard patted down their clothes, the other withdrew a stunner,
+held it on ready. Tawney prowled the lounge. He glanced at the food on
+the table, then reached under the chair cushion and withdrew the
+disconnected microphone, looked at the loose wires, and tossed it aside.
+
+"They're clean," the guard said.
+
+Tawney's face was a study of uneasiness, but he clearly could not
+pinpoint what the trouble was. Finally he shrugged, turned on the smile
+again, although his eyes remained watchful. "Well, maybe you won't mind
+if I join in the talking for a while," he said. "You've been
+comfortable? No complaints?"
+
+"No complaints," Greg said.
+
+"Then I presume we're ready to talk business." He looked at Greg.
+
+"You said you were ready to bargain," Greg said, "but I haven't heard
+any terms yet."
+
+"Terms? Very simple. You direct us to the lode, we give you half of
+everything we realize from it," Tawney said, smiling.
+
+"You mean you'll write us a contract? With a U.N. witness to it?"
+
+"Well, hardly ... under the circumstances. I'm afraid you'll have to
+take our word."
+
+Greg looked at the company man, and shook his head. "Not that I don't
+trust you," he said, "but I'm afraid I can't give you what you want,"
+Greg said.
+
+"Why not?"
+
+"Because I don't know where Dad made his strike."
+
+The company man's face darkened. "Somebody knows where it is. Your
+father would never have found something like that without telling his
+own sons...."
+
+"Sorry," Greg said. "Of course, I can tell you where you can find out,
+if you want to go look."
+
+"We've already searched his records...."
+
+"_Some_ of his records," Greg said. "Not all of them. There was a
+compartment behind the main control panel in Dad's orbit-ship. Dad used
+it to store deeds, claims, other important papers. There was a packet of
+notes in there before your men fired on the ship. But of course, maybe
+you searched more thoroughly, the second time."
+
+Tawney stared at him for a moment, then at Johnny. Johnny Coombs
+shrugged his shoulders solemnly, and shook his head. Without a word, the
+little company man walked to the intercom speaker on the wall. He spoke
+sharply into it, waited, then had a brief, pungent conversation with
+someone. Then he turned back to Greg, his face heavy with suspicion.
+"You saw these papers?"
+
+"Certainly I saw them. I didn't have time to read them through, but what
+else could they be?"
+
+"Let me warn you," Tawney said coldly, "if I send a crew out there on a
+wild goose chase, the party will be over when they get back, do you
+understand? You've been given every consideration. If this is a fool's
+errand, you'll pay for it very dearly." He turned on his heel, snarled
+at one of the guards. "I want them watched every minute," he said. "One
+of you stay with them constantly. It won't take long to find out if this
+is a stall...."
+
+He stalked out, and the hatchway clanged behind him. One guard went
+along; the big one with the stunner stayed behind, eyeing his prisoners
+unpleasantly. The stunner was in his hand, the safety off.
+
+Johnny Coombs started across the room toward the kitchennette, passing
+close to the guard. Suddenly he turned, swung his fist heavily down on
+the guard's neck. The stunner crackled, but Greg had jumped aside.
+Another blow from Johnny's fist sent the gun flying. Another blow, and
+the guard's legs slid out from under him. He fell unconscious to the
+floor.
+
+In an instant they were across the room, lifting down the grill, helping
+Tom out of his hiding place. "Okay, boy," Johnny said to Greg, "I guess
+you pulled the trigger with that story of yours."
+
+"Not me," Greg said. "Tom did. He's the one that showed us the way
+out ... the same way he came in."
+
+ * * * * *
+
+The guard was out for a while, they made sure of that first. Then there
+was a hasty consultation. "The airlocks are guarded," Johnny said, "and
+if they tumble to the ventilator shafts, they can smoke us out in no
+time. How are we going to get a scout-ship without showing ourselves?
+For that matter, how are we going to get a scout-ship away from here
+without being blown up the way the _Scavenger_ was blown up?"
+
+"I think I know a way," Tom said. "We have to have something to keep a
+lot of the crew busy. If we could get to the ship's generators and put
+them out of commission somehow, it might do it."
+
+"Why?" Greg wanted to know.
+
+"Because of the air supply," Tom said. "Without the generators, the fans
+won't run. They'll have to get a crew to fix them or they'll suffocate."
+
+"But that would only take a few men," Johnny said. "As soon as
+the generators went out, they'd look for us, and if we were
+missing ... well, they'd have the whole crew beating the bushes for us.
+It wouldn't be long before somebody thought of the ventilators."
+
+"But we've got to do something, and do it fast," Tom said.
+
+"I know." Johnny chewed his lip. "It's a good idea, but we need more
+than just the generators. We've got to disable the ship ... throw so
+many things at them so fast from so many different directions that they
+don't know which way to turn. That means we'd need to split up, and we'd
+need weapons." He hefted the guard's Markheim. "One stunner between
+three of us isn't enough."
+
+"Well, we have this." Tom unbuckled Roger Hunter's gun case from his
+belt. "Dad's revolver. It's not a stunner, but it might help." He tossed
+the case to Johnny. "I can give you both a rundown on how the shafts go.
+We could plan to meet at a certain spot in a certain length of time...."
+
+He broke off, looking at Johnny. The big miner had taken Roger Hunter's
+gun from the case, and hefted it in his hand, started to check it
+automatically as Tom talked. But now his hand froze as he stared at the
+weapon.
+
+"What's wrong?" Tom asked.
+
+"This gun is wrong," Johnny said. "All wrong. Where did you get this
+thing?"
+
+"From Dad's spacer pack, the one the Patrol brought back. The Major gave
+it to us in Sun Lake City." Tom peered at the gun. "Is it broken or
+something? It's just Dad's revolver...."
+
+"It is, eh?" Johnny turned the gun over in his hand. "Whoever told you
+about guns?"
+
+"What's wrong with it?"
+
+There was an odd expression on Johnny's face as he handed the weapon
+back to Tom. "Take a look at it," he said. "Tell me whether it's loaded
+or not."
+
+Tom looked at it. Except for a few hours on the firing range, he had had
+no experience with guns; he couldn't have taken down a Markheim and
+reassembled it if his life depended on it. But he had seen his father
+take the old revolver out of the leather case many times before.
+
+Now Tom could see that this was not the same gun.
+
+The thing in his hand was large and awkward. The hand-grips didn't fit;
+there was no trigger guard, and no trigger. Several inches along the
+gleaming metal barrel was a shiny stud, and below it a dial with notches
+on it.
+
+"That's funny," Tom said. "I've never seen this thing before."
+
+Greg took it from him, balanced it in his hand. "Doesn't feel right," he
+said. "All out of balance."
+
+"Look at the barrel," Johnny said quietly.
+
+Greg looked. There was no hole in the end of the barrel. "This thing's
+crazy," he said.
+
+"And then some," Johnny said. "You haven't had this out of the case
+since you took it from the pack?"
+
+"Just once," said Tom. "And I put it right back. I hardly looked at it.
+Look, maybe it's just a new model Dad got."
+
+"It's no new model. I'm not even sure it's a gun," Johnny said. "Doesn't
+_feel_ like a gun."
+
+"What happens when you push the stud here?" Greg asked.
+
+Johnny licked his lips nervously. "Try it," he said.
+
+Greg leveled the thing at the rear wall of the lounge and pressed the
+stud. There was a sharp buzzing sound, and a blinding flash of blue
+light against the wall. It looked for all the world like the flash of a
+live power line shorting out. They squinted at the flash, rubbed their
+eyes....
+
+And stared at the wall. Or at what was left of the wall, because most of
+the wall was gone. The metal had bellied out in a six-foot hole into the
+storage hold beyond....
+
+Johnny Coombs whistled. "This thing did _that_?" he whispered.
+
+"It must have...."
+
+"But there's no gun ever made that could do that." He walked over to the
+hole in the wall. "That's half-inch steel plate. There's no way to pack
+that kind of energy into a hand gun."
+
+They stared at the innocent-looking weapon in Greg's hand. "Whatever it
+is, Dad must have put it in the gun-case."
+
+"Yes, he must have," Johnny said.
+
+"Well, don't you see what that means? _Dad must have found it
+somewhere_. Somewhere out here in the Belt ... a gun that no man could
+have made...."
+
+He took the weapon, ran his finger along the gleaming barrel. "I
+wonder," he said, "what else Dad might have found out there."
+
+ * * * * *
+
+Somewhere below them they heard a hatch clang shut, and even deeper in
+the ship generator motors began throbbing in a steady even rhythm. In
+the silence of the lounge they could hear their own breathing, and
+outside a thousand tiny sounds of the ship's activity were audible.
+
+But now they had attention only for the odd-shaped piece of metal in
+Greg's hand, and for the hole that gaped in the wall.
+
+"You think that _this_ was what Dad found?" Greg said. "The Big Strike
+he told Johnny about?"
+
+"It must be part of it," Tom said.
+
+"But what is it? And where did it come from? It doesn't make sense,"
+Greg protested.
+
+"It doesn't make sense the way we've been looking at it," Tom said. "All
+we've found was some gobbledegook in Dad's private log to tell us what
+he found ... but it couldn't have been a vein of ore, or Tawney's men
+would have unearthed it. It had to be something else. Something that was
+so big and important that Dad didn't even dare let Johnny in on it."
+
+"Yes, that's been the craziest part of it, to me," Johnny said. "I've
+done a lot of mining with your Dad. If he'd hit rich ore, he would have
+taken me out there to mine it with him. But he didn't. He said it was
+something he had to work on alone for a while, and he sent me back."
+
+"As if he'd found something that scared him," Tom said, "or something
+that he didn't understand. He was _afraid_ to tell anybody. And whatever
+he found, he managed to hide it somewhere, so that nobody would find
+it...."
+
+"Then why didn't he hide this part of it, too?" Greg said.
+
+"Maybe to be sure there was some trace left, if anything happened to
+him," Tom said.
+
+They were silent for a moment. The only sound was the stertorous
+breathing of the unconscious guard. "Well," Greg said finally, "I have
+to admit it makes sense. It makes other things add up better, too. Dad
+was no fool, he must have known that Tawney was onto something. And Dad
+would never have risked his life for an ore strike. He'd either have
+made a deal with Tawney or let him hijack the lode, if that was all
+there was to it. But there's still one big question ... where did he
+hide what he found? And we aren't going to find the answer here." He
+walked over to the hole in the wall.
+
+"Made quite a mess of it, didn't it?" Johnny said.
+
+"Looks like it. I wonder what that thing would do to a ship's generator
+plant." He turned to Johnny. "We haven't much time. With this thing, we
+could tear this ship apart, leave them so confused they'll never know
+what broke loose. And if we could get that gun back to Major Briarton,
+he'd have to listen to us, and get the U.N. Patrol into the search...."
+
+They had been so intent on their talking that they did not hear the
+footsteps in the corridor until the door swung open. It was another
+guard, the one who had departed with Tawney. He stopped short, blinking
+at his companion on the floor, and then at the gaping hole in the wall.
+When he saw the twins, side by side, his jaw sagged and a strangled
+sound came from his throat.
+
+Then Johnny grabbed his arm, jerked him into the lounge, and slammed the
+hatch shut. Greg pulled the stunner from his holster and tossed it to
+Tom. The guard let out a roar, twisted free, and met Johnny's fist as he
+came around. He sagged at the knees and slid to the floor beside the
+other guard. "All right," Johnny said, "we've dealt the cards, now we'd
+better play the hand. Tom, you first."
+
+Tom pulled the ventilator grill down, and climbed up into the shaft.
+Greg followed, with Johnny at his heels, pulling the grill back up into
+place from the inside. They waited for a moment, but there was no sound
+from the lounge.
+
+"All right," Johnny said breathlessly. "Let's move."
+
+Swiftly they started down the dark tunnel.
+
+
+
+
+11. The Haunted Ship
+
+
+They did not pause, even to catch their breath, for the first twenty
+minutes as Tom led them swiftly and silently down through the maze of
+corridors and chutes that made up the ventilation system of the huge
+ship. Greg lost his bearing completely in the first twenty seconds; each
+time his brother paused at a junction of tubes, he felt a wave of panic
+rise up in his throat ... suppose they lost themselves in here! He heard
+Johnny's trousers flapping behind him, saw Tom's figure flit past
+another grill up ahead, and plunged doggedly on.
+
+It was amazingly hard to move quietly. Even in stocking feet they made a
+soft thud with each footfall.
+
+But there was no sign of detection, no sound of alarm. Finally they came
+out into a large shaft which allowed them to stand upright, and they
+stopped to catch their breath.
+
+"Main tube to the living quarters," Tom said when they had caught up to
+him. "Joins with the lower-level tube by a series of chutes. We've
+actually been circumnavigating the ship ... I wanted to get as far away
+from that lounge compartment as possible, in case they check up on you
+right away."
+
+"We can't have much time," Johnny said. "That second guard must have
+been coming to relieve the other, and when the first one doesn't report
+back, they'll smell something fishy."
+
+ * * * * *
+
+They talked it over for a moment. Johnny had been careful to leave the
+hatchway into the corridor ajar before he climbed into the ventilator
+shaft, and then he had pulled the shaft snugly into place behind him.
+Anyone who came would find two unconscious guards, a burnt-out hole in
+the wall, and the door unlocked.
+
+"We'll hope that he takes things at face value, and assumes we're at
+large in the ship somewhere, for a while at least," Johnny said. "That
+hole in the wall is going to set them back a couple of steps, too."
+
+"But they'll sound the alarm, at least," Tom said.
+
+"You bet they will! They'll have every man on the crew shaking down the
+ship for us. But they may not think of the ventilators until they can't
+find us anywhere else."
+
+"But sooner or later they're bound to think of it."
+
+"That's true," Johnny said. "Unless they keep seeing us in the ship. The
+way I figure it, this crew has been on battle stations plenty of times.
+They'll be able to search the whole ship in half an hour. We're just
+going to have to show ourselves ... at least enough to keep them
+searching."
+
+"Well, what if they do think of the ventilators?" Greg said. "They'd
+still have a time finding us."
+
+"Maybe, but don't underestimate Tawney. He might just mask up his crew
+and flood the tubes with cyanide."
+
+They thought about that for a minute. There was no sound here but their
+own breathing, and the low chug-chug-chug of the pumps somewhere deep in
+the ship. Momentarily they expected to hear the raucous clang of the
+alarm bell, as some crew member or another walked into the lounge and
+found them gone. But so far there was no sign they had been discovered
+missing. "No," Johnny said finally, "if we just hide out in here, and
+hope for a chance at one of the scout ships, they'll find us eventually.
+But we've got three big advantages, if we can figure out how to use
+them. That fancy gun, for one. A way to get around the ship, for
+another ... and the fact that there's one more of us than they count on."
+He flipped on his pocket flash, began drawing lines on the dusty floor of
+the shaft. "My idea is to keep them so busy fighting little fires that
+they won't have a chance to worry about where the big one is."
+
+He drew a rough outline-sketch of the organization of the ship. "This
+look right to you, from what you've seen?" he asked Tom.
+
+"Pretty much," Tom said. "There are more connecting tubes."
+
+"All the better. We want to get the generators with our little toy here
+first. That'll darken the ship, and put the blowers out of commission in
+case they think of using gas. Also, it will cut out their computers and
+missile-launching rigs, which might give us a chance to get a scout-ship
+away in one piece if we could get aboard one."
+
+"All right, the generators are first," Tom said. "But then what? There
+are four hundred men on this ship. They'll have every airlock triple
+guarded. They'll block us for sure."
+
+"Not when we get through, they won't," Johnny grinned. "We've got an old
+friend aboard who's going to help us."
+
+"_Friend?_"
+
+"Ever hear of panic?" Johnny said. "Just listen a minute."
+
+Quickly then, he outlined his plan. Tom and Greg listened, watched
+Johnny make marks with his finger in the dust. When he finished, Greg
+whistled softly. "You missed your life work," he said. "You should have
+gone into crime."
+
+"If I'd had a ghost to help me, I might have," Johnny said.
+
+"It's perfect," Tom said, "if it works. But it all depends on one
+thing ... keeping it rolling after we start...."
+
+For another five minutes they went over the details. Then Johnny clapped
+them each on the shoulder. "It's up to you two," he said. "Let's go."
+
+They moved down the large shaft to the place where it broke into several
+spurs. Johnny started down the chute toward the engine rooms; Tom and
+Greg headed in opposite directions toward the main body of the ship.
+Just as they broke up, they heard a muffled metallic sound from the
+nearest compartment grill.
+
+It was the _clang-clang-clang_ of the orbit-ship's general alarm.
+
+ * * * * *
+
+Crewmen stopped with food halfway to their mouths, jerked away from
+tables. Orders buzzed along a dozen wires, and section chiefs began
+reporting their battle-stations alert and ready. Finally Tawney snapped
+on the general public address system speaker. "Now get this," he roared.
+"I want every inch of this ship searched ... every corridor, every
+compartment. I want a special crew standing by for missile launching.
+I want double guards at every airlock. If they get a ship away from
+here, the man who lets them through had better be dead when I find
+him...." He broke off, clutching the speaker until his voice was under
+control again. "All right, move. They're armed, but there's no place they
+can go. Find them."
+
+A section-chief came back over the speaker. "Dead or alive, boss?"
+
+"Alive, you idiot! At least the Hunter brat. I'll take the other one any
+way you can get him."
+
+He switched off, and waited, pacing the control cabin like a caged
+animal. Ten minutes later a buzzer sounded. "Hydroponics, boss. All
+clear."
+
+"No sign of them?"
+
+"Nothing."
+
+Another buzz. "Number seven ore hold. Nothing here."
+
+Still another buzz. "Crew's quarters. Nothing, boss."
+
+One by one the reports came in. Fuming, Tawney checked off the sections,
+watched the net draw tighter throughout the ship. They were somewhere,
+they _had_ to be....
+
+But nobody seemed to find them.
+
+He was buzzing for his first mate when the power went off. The lights
+went out, the speaker went dead in his hand. The computers sighed
+contentedly and stopped computing. Abruptly the emergency circuits went
+into operation, flooding the darkness with harsh white lights. The
+intercom started buzzing again.
+
+"Engine room, boss."
+
+"What happened down there?" Tawney roared.
+
+The man sounded like he'd just run the mile. "Generators," he panted.
+"Blown out."
+
+"Well, get somebody in there to fix them. Have a crew seal off the
+area...."
+
+"Can't, boss. Fix them, I mean."
+
+"Why not? What have we got electricians for?"
+
+"There's nothing left to fix. The generators aren't wrecked ... they're
+demolished...."
+
+"Then get the pair that did it...."
+
+"They're not here. We've been sealed up tight. There's no way anybody
+could have gotten in here...."
+
+After that, things began to get confusing.
+
+ * * * * *
+
+For a while Merrill Tawney thought that his crew was going crazy ... and
+then he began to wonder if he were the one who was losing his mind.
+
+Whatever the case, Merrill Tawney was certain of one thing. The things
+that were happening on his orbit-ship could not possibly be happening.
+
+A guard in one of the outer shell storage holds called in with a
+disquieting report. Greg Hunter, it seemed, had just been spotted
+vanishing into one of the storage compartments from the main outer-shell
+corridor. When the guard had broken through the jammed hatchway to
+collar his trapped victim, there was no sign of the victim anywhere
+around.
+
+At the same moment, a report came in from a guard on the opposite side
+of the ship. He had just spotted Greg Hunter _there_, it seemed, moving
+down a spur corridor. The guard had held his fire (according to Tawney's
+orders) and summoned help to corner the quarry ... but when help
+arrived, the quarry had vanished.
+
+ * * * * *
+
+Five minutes later the Hunter boy was discovered in the Hydroponics
+section, busily reducing all the yeast vats to shambles with a curious
+weapon that seemed to eat holes in things. It ate the deck out from
+under the guard's feet, sending him plunging through the floor into the
+galley. By the time he had scrambled back again, the Hunter boy was
+gone, and a rapid move to seal off the region failed to turn him up
+again. The guard was upset; Tawney was a great deal more upset, because
+at the time Greg Hunter was (reportedly) playing havoc with the
+yeast-vats in Hydroponics he was also (reportedly) knocking guards down
+like ten-pins in the main corridor off the engine room while
+reinforcements tried to pin him down with a wide-beam stunner....
+
+Quite suddenly emergency circuits closed and lights flashed in the
+control cabin, the special signal for a meteor-collision with the outer
+shell in No. 3 hold. Tawney signalled for the section chief frantically.
+"What's happening down there?"
+
+"I can't talk," the section chief gasped. "Gotta get into a suit, we're
+leaking in here...."
+
+"Well, plug up the hole!"
+
+"The hole's four feet wide, sir!" There was a fit of coughing and the
+contact broke. The signals for No. 4 hold and No. 5 hold were flashing
+now; while the crew members in the vicinity scrambled for pressure suits
+someone systematically proceeded to blow holes in No. 9, No. 10 and No.
+11 holds....
+
+It was impossible. The reports came in thick and fast. Greg Hunter
+was in two places at once, and everywhere he went ... in both
+places ... there was a trail of unbelievable destruction. Bulkheads
+demolished, gaping holes torn in the outer shell, the air-reconditioning
+units smashed beyond repair.... Tawney buzzed for his first mate.
+
+An emergency switch cut into the line, with the frantic voice of a
+section chief. Johnny Coombs had been spotted disappearing into the
+ventilator shaft in the engine sector. "Well, go in after him!" Tawney
+screamed. He got his first mate finally, and snarled orders into the
+speaker. "They're in the ventilators. Get a crew in there and stop
+them."
+
+But it was dark in the ventilator shafts. No emergency lights in there.
+Worse, the crewmen were hearing the things that were being whispered
+around the ship. The ventilator shafts yawned menacingly before them;
+they went in reluctantly. Once in the dark maze of tunnels,
+identification was difficult. Two guards met each other headlong in the
+darkness, and put each other out of the fight in a flurry of nervous
+stunner-fire. While they searched more of the holds were broken open,
+leaking air through gaping rents in the hull....
+
+Tawney felt the panic spreading; he tried to curb it, and it spread in
+spite of him. The fugitives were appearing and disappearing like
+wraiths. Reports back to control cabin took on a frantic note, confused
+and garbled. Now the second-level bulkheads were being attacked. Over a
+third of the compartments were leaking precious air into outer space.
+
+When a terrified section chief came through with a report that two Greg
+Hunters had been spotted by the same man at the same time, and that the
+guards in the sector were shooting at anything that moved, including
+other guards, Tawney made his way to the radio cabin and put through a
+frantic signal to Jupiter Equilateral headquarters on Mars.
+
+The contact took forever, even with the ship's powerful emergency
+boosters. By the time someone at headquarters was reading him, Tawney's
+report sounded confused. He was trying for the third time to explain,
+clearly and logically, how two men and a ghost were scuttling his
+orbit-ship under his very feet when one wall of the cabin vanished in a
+crackle of blue fire, and he found himself staring at two Greg Hunters
+and a grim-faced Johnny Coombs.
+
+He made squeaky noises into the microphone and dropped it with a crash.
+He groped for a chair; Johnny jerked him to his feet again. "A
+scout-ship," he said tersely. "Clear it for launching. We want one with
+plenty of fuel, and we don't want a single guard anywhere near the
+airlock." He picked up an intercom microphone and thrust it into the
+little fat man's trembling hand. "Now move! And you'd better be sure
+they understand you, because you're coming with us."
+
+Merrill Tawney stared first at Tom, then at Greg, and finally at the
+microphone. Then he moved. The orders he gave to his section chiefs were
+very clear and concise.
+
+He had never argued with a ghost before, and he didn't care to start
+now.
+
+ * * * * *
+
+It was over so quickly that it seemed to Tom it had just begun, and if
+so much had not been at stake, it might have been fun.
+
+It had been the gun ... the remarkable gun that Roger Hunter had left as
+his legacy ... that had been the key. It ate through steel and aluminum
+alloy like putty. Whatever its power source, however it worked, by
+whatever means it had been built, there had been no match for it on the
+orbit-ship.
+
+It had _worked_ ... and that was all that mattered right then.
+
+With it, and with the advantage of a ghost that walked like a
+man ... Tom Hunter, to be exact ... they had reduced the Jupiter
+Equilateral orbit-ship to a smoking wreck in something less than thirty
+minutes.
+
+The signal came back that a scout-ship was ready, unguarded. Johnny
+prodded Tawney with the stunner. "You first," he said.
+
+"But where are you taking me?"
+
+"You'll see," Johnny said.
+
+"It was a trick," Tawney said, glaring at Tom. "They told me they shot
+your ship to pieces...."
+
+"The ship, yes," Tom said. "Not me."
+
+"Well ... well, that's good, that's good," Tawney said quickly. He
+turned to Greg. "You don't have to take me back ... the bargain is still
+good...."
+
+"Move," Johnny Coombs said.
+
+With Tawney between them, Greg and Tom marched down the corridor toward
+the airlock, with Johnny bringing up the rear. No one stopped them. No
+one even came near them. One crewman stumbled on them in the corridor;
+he saw Tawney with a gun in his back, and fled in terror.
+
+They found the scout-ship, and strapped Tawney down to an accelleration
+bunk, binding his hands and feet so he couldn't move. Greg checked the
+controls while Tom and Johnny strapped down. A moment later the engines
+fired, and the leaking wreck of the orbit-ship fell away, dwindling and
+disappearing in the blackness of space.
+
+It was a quiet journey. The red dot that was Mars grew larger every
+hour. One of the three stayed awake at all times to watch Tawney while
+the others slept. During the second rest period, Tom woke up while Greg
+was on duty.
+
+"How's our prisoner doing?" Tom asked.
+
+"No problem there, he can barely move. I almost wish he'd try something,
+he's too quiet."
+
+It was true. Tawney had recovered from his shock ... but rather than
+grow more worried as Mars grew large on the screen, he seemed to become
+more cheerful by the minute. "He doesn't seem very worried, does he?"
+Tom said.
+
+"No, and it doesn't quite add. We've got enough on him to get Jupiter
+Equilateral pushed right out of the Belt."
+
+"I'd still feel better if we had the whole picture for the Major," Tom
+said. "We still don't know what Dad found, or where he hid it...."
+
+The uneasiness grew. Tawney ignored them, staring at the image of the
+red planet on the viewscreen almost eagerly. Then, eight hours out of
+Sun Lake City a U.N. Patrol ship appeared, moving toward them swiftly.
+"Intercepting orbit," Greg said. "Looks like they were waiting for us."
+
+They watched as the big ship moved in to tangential orbit, matching its
+speed to theirs. Then Greg snapped the communicator switch. "Sound off,"
+he said cheerfully. "We've got a prize for you."
+
+"Stand by, we're boarding you," the Patrol sent back. "And put your
+weapons aside."
+
+Four scooters broke from the side of the Patrol ship. Greg activated the
+airlock. Five minutes later a man in Patrol uniform with captain's bars
+stepped into the control cabin, a stunner on ready in his hand. Three
+Patrolmen came in behind him.
+
+The captain looked around the cabin, then saw Tawney, and took a deep
+breath. "Well, thank the stars you're safe at any rate. Pete, Jimmy,
+take the controls."
+
+"Hold on," Greg said. "We don't need a pilot."
+
+The Captain looked at him. "Sorry, but we're taking you in. There won't
+be any trouble unless you make it. You three are under arrest, and I'm
+authorized to make it stick if I have to. I suggest you just cooperate."
+
+They stared at him. Then Johnny said, "What are the charges?"
+
+"You ought to know," the Captain said. "We have a formal complaint from
+the main offices of Jupiter Equilateral, charging you with piracy,
+murder, kidnapping of a company official, and totally wrecking a company
+orbit ship. I don't quite see how you managed it, but we're going to
+find out in short order."
+
+There was a stunned silence in the cabin, and then a sound came from the
+rear of the cabin.
+
+Merrill Tawney was laughing.
+
+
+
+
+12. The Sinister Bonanza
+
+
+They were taken to a small, drab internment room. A half hour passed and
+still no word from the Major. From the moment the Patrol crew had
+boarded them, everything had seemed like a bad dream. The shock of the
+arrest, the realization that the Captain had been serious when he reeled
+off the charges lodged against them ... they had been certain it was
+some kind of ill-planned joke until they saw the delegation of Jupiter
+Equilateral officials waiting at the port to greet Merrill Tawney like a
+man returned from the dead. They had watched Tawney climb into the sleek
+company car and drive off toward the gate, while the Captain had
+escorted them without a word down to the internment rooms.
+
+The door clicked, and the Captain looked in. "All right, come along
+now," he said.
+
+"Is the Major here?" Tom said.
+
+"You'll see the Major soon enough." The Captain herded them into another
+room, where a clerk efficiently fingerprinted them. Then they went down
+a ramp to a jitney-platform, and boarded a U.N. official car. The trip
+into the city was slow; rush-hour traffic from the port was heavy. When
+they reached U.N. headquarters, there was another wait in an upper
+level ante-room. The Captain stood stiffly with his hands behind his
+back and ignored them.
+
+"Look, this is ridiculous," Greg burst out finally. "We haven't done
+anything. You haven't even let us make a statement."
+
+"Make your statement to the Major. It's his headache, not mine, I'm
+happy to say."
+
+"But you let that man walk out of there scot free...."
+
+The Captain looked at him. "If I were you," he said, "I'd stop
+complaining and start worrying. If I had Jupiter Equilateral at my
+throat, I'd worry plenty, because once they start they don't stop."
+
+A signal light blinked, and he took them downstairs. Major Briarton was
+behind his desk; his eyes tired, his face grim. He dismissed the
+Captain, and motioned them to seats. "All right, let's have the story,"
+he said, "and by the ten moons of Saturn it had better be convincing,
+because I've about had my fill of you three."
+
+He listened without interruption as Tom told the story, with Greg and
+Johnny adding details from time to time. Tom told him everything, from
+the moment they had blasted off for Roger Hunter's claim to the moment
+the Patrol ship had boarded them, except for a single detail.
+
+He didn't mention the remarkable gun from Roger Hunter's gun case. The
+gun was still in the spacer's pack he had slung over his shoulder; he
+had not mentioned it when the Patrolmen had taken their stunners away.
+Now as he talked, he felt a twinge of guilt in not mentioning it....
+
+But he had a reason. Dad had died to keep that gun secret. It seemed
+only right to keep the secret a little longer. When he came to the part
+about their weapons, he simply spoke of "Dad's gun" and omitted any
+details.
+
+And through the story, the Major listened intently, interrupting only
+occasionally, pulling at his lip and scowling.
+
+"So we decided that the best way to convince you that we had the
+evidence you wanted was to bring Tawney back with us," Tom concluded.
+
+"A brilliant maneuver," the Major said dryly. "A real stroke of genius."
+
+"But then the Patrol ship intercepted us and told us we were under
+arrest. And when we landed, they let Tawney drive off without even
+questioning him."
+
+"The least we could do, under the circumstances," the Major said.
+
+"Well, I'd like to know why," Greg broke in bitterly. "Why pick on us?
+We've just been telling you...."
+
+"Yes, yes, I heard every word of it," the Major sighed. "If you knew the
+trouble ... oh, what's the use? I've spent the last three solid hours
+talking myself hoarse, throwing in every bit of authority I could
+muster and jeopardizing my position as Coordinator here, for the sole
+purpose of keeping you three idiots out of jail for a few hours."
+
+"Jail!"
+
+"That's what I said. The brig. The place they put people when they don't
+behave. You three are sitting on a nice, big powder keg right now, and
+when it blows I don't know how much of you is going to be left."
+
+"Do you think we're lying?" Greg said.
+
+"Do you know what you're charged with?" the Major snapped back.
+
+"Some sort of nonsense about piracy...."
+
+"Plus kidnapping. Plus murder. To say nothing of totally disabling a
+seventeen-million-dollar orbit-ship and placing the lives of four
+hundred crewmen in jeopardy." The Major picked up a sheet of paper from
+his desk. "According to Merrill Tawney's statement, the three of you
+hijacked a company scout-ship that chanced to be scouting in the
+vicinity of your father's claim. Your attack was unprovoked and violent.
+Everybody on Mars knows you were convinced that Jupiter Equilateral was
+responsible for your father's death." He looked up. "In the absence of
+any evidence, I might add, although I did my best to tell you that." He
+rattled the report-sheet. "All right. You took the scout-ship by force,
+with the pilot at gunpoint, and made him home in on his orbit-ship. Then
+you proceeded to reduce that orbit-ship to a leaking wreck, although
+Tawney tried to reason with you and even offered you amnesty if you
+would desist. By the time the crew stopped shooting each other in the
+dark ... fifteen of them subsequently expired, it says here ... you had
+stolen another scout-ship and kidnapped Tawney for the purpose of
+extorting a confession out of Jupiter Equilateral, threatening him with
+torture if he did not comply...." The Major dropped the paper to the
+desk.
+
+Johnny Coombs picked it up, looked at it owlishly, and put it back
+again. "Pretty large operation for three men, Major," he said.
+
+The Major shrugged. "You were armed. That orbit-ship was registered as a
+commercial vessel. It had no reason to expect a surprise attack, and had
+no way to defend itself."
+
+"They were armed to the teeth," Greg said disgustedly. "Why don't you
+send somebody out to look?"
+
+"Oh, I could, but why waste the time and fuel? There wouldn't be any
+weapons aboard."
+
+"Then how do they explain the fact that the _Scavenger_ was blown to
+bits and Dad's orbit-ship ripped apart from top to bottom?"
+
+"Details," the Major said. "Mere details. I'm sure that the company's
+lawyers can muddy the waters quite enough so that little details like
+that are overlooked. Particularly with a sympathetic jury and a judge
+that plays along."
+
+He stood up and ran his hand through his hair. "All right, granted I'm
+painting the worst picture possible ... but I'm afraid that's the way
+it's going to be. I believe your story, don't worry about that. I know
+why you went out there to the Belt and I can't really blame you, I
+suppose. But you were asking for trouble, and that's what you got.
+Frankly, I am amazed that you ever returned to Mars, and how you managed
+to make rubble of an orbit-ship with a crew of four hundred men trying
+to stop you is more than I can comprehend. But you did it. All right,
+fine. You were justified; they attacked you, held you prisoner,
+threatened you. Fine. They'd have cut your throats in another few hours,
+perhaps. Fine. I believe you. But there's one big question that you
+can't answer, and unless you can no court in the Solar System will
+listen to you."
+
+"What question?" Tom said.
+
+"The question of motives," the Major replied. "You had plenty of motive
+for doing what Tawney says you did. But what motive did Jupiter
+Equilateral have, if your story is true?"
+
+"They wanted to get what Dad found, out in the Belt."
+
+"Ah, yes, that mysterious bonanza that Roger Hunter found. I was afraid
+that was what you'd say. And it's the reason that Jupiter Equilateral is
+going to win this fight, and you're going to lose it."
+
+"I don't think I understand," Tom said slowly.
+
+"I mean that I'm going to have to testify against you," the Major said.
+"_Because your father didn't find a thing in the Asteroid Belt_, and I
+happen to know it."
+
+ * * * * *
+
+"It's been a war," the Major said later, "a dirty vicious war with no
+holds barred and no quarter given. Not a shooting war, of course,
+nothing out in the open ... but a war just the same, with the highest
+stakes of any war in history.
+
+"It didn't look like a war, at first," the Major went on. "Back when the
+colonies were being built, nobody really believed that anything of value
+would come of them ... scientific outposts, perhaps, places for
+laboratories and observatories, not much more. The colonies were placed
+under United Nations control. Nobody argued about it.
+
+"And then things began to change. There was wealth out here ... and
+opportunities for power. With the overpopulation at home, Earth was
+looking more and more to Mars and Venus for a place to move ... not tiny
+colonies, but places for millions of people. And as Mars grew, Jupiter
+Equilateral grew."
+
+"But it was just a mining company," Tom said.
+
+"At first it was, but then its interests began to expand. The company
+accumulated wealth, unbelievable wealth, and it developed many friends.
+Very soon it had friends back on Earth fighting for it, and the United
+Nations found itself fighting to stay on Mars."
+
+"I don't see why," Tom said. "The company already has half the mining
+claims in the Belt...."
+
+"They aren't interested in the mining," the Major said. "They have a
+much longer-range goal than that. The men behind Jupiter Equilateral are
+looking ahead. They know that someday Earthmen are going to have to go
+to the stars for colonies ... it won't be a matter of choice after a
+while, they'll _have_ to go. Well, Jupiter Equilateral's terms are very
+simple. They're perfectly willing to let the United Nations control
+things on Earth. All they want is control of everything else. Mars, if
+they can drive us out. Venus too, if it ever proves up for colonies. And
+if they can gain control of the ships that leave our Solar System for
+the stars, they can build an empire, and they know it."
+
+They were silent for a moment. Then Johnny Coombs said, "Doesn't anybody
+on Earth know about this?"
+
+"There are some who know ... but they don't see the danger. They think
+of Jupiter Equilateral as just another big company. So far U.N. control
+of Mars and Venus has held up, even though the pressure on the
+legislators back on Earth has been getting heavier and heavier. Jupiter
+Equilateral won the greatest fight in its history when they limited U.N.
+jurisdiction to Mars, and kept us out of the Belt. And now they hope to
+convince the lawmakers that we're incompetent to administer the Martian
+colonies and keep peace out here. If they succeed, we'll be called home
+in nothing flat; we've had to fight just to stay."
+
+The Major spread his hands helplessly. "Like I said, it's been a war.
+Our only hope was to prove that the company was using piracy and murder
+to gain control of the asteroids. We had to find a way to smash the
+picture they've been painting of themselves back on Earth as a big,
+benevolent organization interested only in the best for Earth colonists
+on the planets. We had to expose them before they had the Earth in
+chains ... not now, maybe not even a century from now, but sometime,
+years from now, when the breakthrough to the stars comes and Earthmen
+discover that if they want to leave Earth they have to pay toll...."
+
+"They could never do that!" Greg protested.
+
+"They're doing it, son. And they're winning. We have been searching
+desperately for a way to fight back, and that was where your father came
+in. He could see the handwriting, he knew what was happening. That was
+why he broke with the company and tried to organize a competing force
+before it was too late. And it was why he died in the Belt. He knew I
+couldn't send an agent out there without unquestionable evidence of
+major crime of some sort or another. But a private citizen could go out
+there, and if he happened to be working with the U.N. hand in glove,
+nobody could do anything about it."
+
+"Then Dad was a U.N. agent?"
+
+"Oh, not officially. There's not a word in the records. If I were forced
+to testify under oath, I would have to deny any connection. But
+unofficially, he went out there to lay a trap."
+
+The Major told them then. It had been an incredible risk that Roger
+Hunter had taken, but the decision had been his. The plan was simple: to
+involve Jupiter Equilateral in a case of claim-jumping and piracy that
+would hold up in court, pressed by a man who would not be intimidated
+and could not be bought out. Roger Hunter had made a trip to the Belt
+and come back with stories ... very carefully planted in just the right
+ears ... of a fabulous strike. He knew that Jupiter Equilateral had
+jumped a hundred rich claims in the past, forcing the independent miners
+to agree, frightening them into silence or disposing of them with
+"accidents."
+
+But this was one claim they were not going to jump. The U.N. cooperated,
+helping him spread the story of his Big Strike until they were certain
+that Jupiter Equilateral would go for the bait. Then Roger Hunter had
+returned to the Belt, with a U.N. Patrol ship close by in case he needed
+help.
+
+"We thought it would be enough," the Major said unhappily. "We were
+wrong, of course. At first nothing happened ... not a sign of a company
+ship, nothing. Your father contacted me finally. He was ready to give
+up. Somehow they must have learned that it was a trap. But they had just
+been careful, was all. They waited until our guard was down, and then
+moved in fast and hit hard."
+
+He sank down in his seat behind the desk, regarding the Hunter twins
+sadly. "You know the rest. Perhaps you can see now why I tried to keep
+you from going out there. There was no proof to uncover and no bonanza
+lode for you to find. There never was a bonanza lode."
+
+The twins looked at each other, and then at the Major. "Why didn't you
+tell us?" Greg said.
+
+"Would you have listened? Would telling you have kept you from going out
+there? There was no point to telling you, I knew you would have to find
+out for yourselves, however painfully. But what I'm telling you now is
+the truth."
+
+"As far as it goes," Tom Hunter said. "But if this is really the truth,
+there's one thing that doesn't fit into the picture."
+
+Slowly Tom pulled the gun case from his pack and set it down on the
+Major's desk. "It doesn't explain what Dad was doing with this."
+
+
+
+
+13. Pinpoint in Space
+
+
+Tom knew now that it was the right thing to do. There was no question,
+after the Major's story, of what Dad had been doing out in the Belt at
+the time he had been killed. He had been doing a job that was more
+important to him than asteroid mining ... but he had found something
+more important than his own life, and had no chance to send word of what
+he had found back to Major Briarton on Mars. That had been the
+unforeseeable part of the trap.
+
+But now, of course, the Major had to know.
+
+The Mars Coordinator looked at the thing on the desk for a long moment
+before he reached out to touch it. The bright metal gleamed in the
+light, pale gray, lustrous. The Major picked it up, balanced it expertly
+in his hand, and a puzzled frown clouded his face. He examined it
+minutely.
+
+"What is this thing?" he said.
+
+"Suppose you tell us," Johnny Coombs said from across the room.
+
+"It looks like a gun."
+
+"That's what it is, all right."
+
+"You've fired it?"
+
+"Yes ... but I wouldn't fire it in here, if I were you," Johnny said.
+"You were wondering how we wrecked Tawney's orbit-ship so thoroughly.
+That's your answer right there." He told about the hole in the bulkhead,
+the way the ship's generators had melted like clay under the powerful
+blast of the weapon.
+
+The Major could hardly control his excitement. "Where did you get it?"
+he asked, turning to Tom.
+
+"From the space pack that you turned over to us. I didn't even look at
+it, until we needed a gun in a hurry. I just assumed it was Dad's
+revolver."
+
+"And your father found it somewhere in the Belt," the Major said softly.
+He looked at the weapon again, shaking his head. "There isn't any such
+gun," he said finally. "These things you say it could do ... they would
+require energy enough to break down the cohesive forces of molecules.
+There isn't any way we know of to harness that kind of energy and
+channel it in a hand weapon. Nobody on Earth...."
+
+He broke off and stared at them.
+
+"That's right," Johnny said. "Nobody on Earth."
+
+"You mean ... extraterrestrial?"
+
+"There isn't any other answer," Johnny said. "_Look_ at the thing,
+Major. _Feel_ it. Does it feel like it was made for a human hand? It
+doesn't fit, it doesn't balance, you have to hold it with both hands to
+aim it...."
+
+"_But where did it come from?_" the Major said. "We've never had
+visitors from another star system ... not in the course of recorded
+history. And we know that Earthmen are the only intelligent creatures in
+our Solar System."
+
+"You mean that they're the only ones _now_," Tom said.
+
+"Or any other time."
+
+"We don't know that, for sure," Tom said.
+
+"Look, we've explored Venus, Mars, all the major satellites. If there
+had ever been intelligence on any of them, we'd have known it."
+
+"Maybe there was a planet that Earthmen haven't explored," Tom said.
+"Even Dad tried to tell us that. The quotation from Kepler that he
+scribbled down in his log ... 'Between Jupiter and Mars I will put a
+planet.' Why would Dad have written that? Unless he had suddenly
+discovered proof that there _had_ been a planet there?"
+
+"You mean this ... this gun," the Major said.
+
+"And whatever else he found."
+
+"But there's never been any proof of that theory ... not even a hint of
+proof."
+
+"Maybe Dad found proof. There are hundreds of thousands of asteroid
+fragments out there in the Belt, and only a few hundred of them have
+ever been examined by men."
+
+On the desk the strange weapon stared up at them. Evidence, mute
+evidence, and yet its very existence said more than a thousand words. It
+was there. It could not be denied.
+
+And someone ... or _something_ ... had made it.
+
+Slowly the Major pulled himself to his feet. "It must have happened
+after his last message to me," he said. "It wasn't part of the scheme we
+had set up, but he made a strike just the same ... an archeological
+strike ... and this gun was part of it." He picked up the weapon, turned
+it over in his hand. "But it was days after that last message before his
+signal went off, and the Patrol ship moved in."
+
+"It makes sense," Johnny Coombs said. "He found the gun, and something
+more."
+
+"Like what?"
+
+"I wouldn't even guess," Johnny said. "A planet with a race of creatures
+intelligent enough and advanced enough to make a weapon like that ... it
+could have been anything. But whatever it was, it must have scared him.
+He must have known that a company ship might turn up any minute ... so
+he hid whatever he had found, and all he dared to leave was a hint."
+
+"And now it's vanished," the Major said. "The big flaw in the whole
+idea. My Patrol ship found nothing when it searched the region. You
+looked, and drew a blank. The company men scoured the area." He spread
+his hands helplessly. "You see, it just won't hold up, not a bit of it.
+Even with this gun, it won't hold up. We've got to find the answer."
+
+"It's out there somewhere," Tom said doggedly. "It's got to be."
+
+"But _where_? Don't you see that everything hangs on that one thing? If
+we could prove that your father found something just before he was
+killed, we could tear Jupiter Equilateral's case against you into
+shreds. We could charge them with piracy and murder, and make it stick.
+We could break their power once and for all ... but until we know what
+Roger Hunter found, we're helpless. They'll take you three to court, and
+I won't be able to stop them. And if you lose that case, it may mean the
+end of U.N. authority on Mars."
+
+"Then there's just one thing to do," Johnny Coombs said. "We've got to
+find Roger Hunter's bonanza."
+
+ * * * * *
+
+It was almost midnight when they left the Major's office, a gloomy trio,
+walking silently up the ramp to the Main Concourse, heading toward the
+living quarters.
+
+They had been talking with the Major for hours, going over every facet
+of the story, wracking their brains for the answer ... but the answer
+had not come.
+
+Roger Hunter had found something, and hidden it so well that three
+groups of searchers had failed to discover it. After seeing the gun, the
+Major was convinced that there had indeed been a discovery made. But
+whatever that discovery had been, it was gone as if it had never
+existed ... as if by some sort of magic it had been turned invisible,
+or conjured away to another part of the Solar System.
+
+Finally, they had given up, at least for the moment. "It has to be
+there," the Major had said wearily. "It hasn't vanished, or miraculously
+ceased to exist. We know he was working on one claim, one asteroid.
+There were no other asteroids in the region ... and even the ones within
+suicide radius have been searched."
+
+"It's there, all right," Tom said. "We're missing something, that's
+all."
+
+"But what? Asteroids have stable orbits. Nobody can just make one
+disappear...."
+
+They had called it a night, finally.
+
+Once home they found more bad news waiting. There were two messages on
+the recordomat. The first was an official summons to appear before the
+United Nations Board of Investigations at 9:00 the following morning to
+answer "certain charges placed against the above named persons by the
+Governing Board of Jupiter Equilateral Mining Industries, and by one
+Merrill Tawney, plaintiff, representing said Governing Board." They
+listened to the plastic record twice. Then Greg tossed it down the waste
+chute.
+
+The other message was addressed to Greg, from the Commanding Officer of
+Project Star-Jump. The message was very polite and regretful; it was
+also very firm. The pressure of the work there, in his absence, made it
+necessary for the Project to suspend Greg on an indefinite leave of
+absence. Application for reinstatement could be made at a later date,
+but acceptance could not be guaranteed....
+
+"Well, I might have expected it," Greg said, "after what the Major told
+us. The money for Star-Jump must have been coming from somewhere, and
+now we know where. The company probably figures to lay claim on any
+star-drive that's ever developed." He dropped the notice down the chute,
+and laughed. "I guess I really asked for it."
+
+"You mean I pushed you into it," Tom said bitterly. "If I'd kept my big
+mouth shut at the very start of this thing, you'd have gone back to the
+Project and that would have been the end of it...."
+
+ * * * * *
+
+Greg looked at him. "You big bum, do you think I really care?" He
+grinned. "Don't feel too guilty, Twin. We've been back to back on this
+one."
+
+He pulled off his shirt and walked into the shower room. Johnny Coombs
+was already stretched out on the sofa, snoring softly.
+
+Quite suddenly the room seemed hot and stuffy, oppressive. He couldn't
+make his thoughts come straight. There had been too much thinking, too
+much speculation. Tom stood up and slipped on his jacket.
+
+He had to walk, to move about, to try to think. He slipped open the
+door, and started for the ramp leading to the Main Concourse.
+
+There was an answer, somewhere.
+
+He walked on along the steel walkways, trying to clear his mind of the
+doubts and questions that were plaguing him. At first he just wandered,
+but presently he realized that he had a destination in mind.
+
+He went up a ramp and across the lobby of the United Nations
+Administration Building. He took a spur off the main corridor, and came
+to a doorway with a small circular staircase beyond it. At the bottom of
+the stairs he opened a steel door and stepped into the Map Room.
+
+It was a small darkened amphitheater, with a curving row of seats along
+one wall. On either side were film viewers and micro-readers. And
+curving around on the far wall, like a huge parabolic mirror, was the
+Map.
+
+Tom had been here many times before, and always he gasped in wonder when
+he saw the awesome beauty of the thing. Stepping into the Map Room was
+like stepping into the center of a huge cathedral. Here was the glowing,
+moving panorama of the Solar System spread out before him in a
+breath-taking three-dimensional image. Standing here before the Map it
+seemed as if he had suddenly become enormous and omnipotent, hanging
+suspended in the blackness of space and staring down at the Solar System
+from a vantage point a million miles away.
+
+Once, Dad had told him, there had been a great statue in the harbor of
+Old New York which had been a symbol of freedom for strangers coming to
+that city from across the sea, and a welcome for countrymen returning
+home. And someday, he knew, this view of the Solar System would be
+waiting to greet Earthmen making their way home from distant stars. The
+Map was only an image, a gift from the United Nations to the colonists
+on Mars, but it reproduced the Solar System in the minutest detail that
+astronomers could make possible.
+
+In the center, glowing like a thing alive, was the Sun, the hub of the
+magnificent wheel. Around it, moving constantly in their orbits, were
+the planets, bright points of light on the velvet blackness of the
+screen. Each orbit was computed and held on the screen by the great
+computer in the vault below.
+
+But there was more on the Map than the Sun and the planets, with their
+satellites. Tiny green lights marked the Earth-Mars and the Earth-Venus
+orbit-ships, moving slowly across the screen. Beyond Mars, a myriad of
+tiny lights projected on the screen, the asteroids. Without the
+magnifier Tom could identify the larger ones ... Ceres, on the opposite
+side of the Sun from Mars now as it moved in its orbit; smaller Juno,
+and Pallas, and Vesta....
+
+For each asteroid which had been identified, and its orbit plotted,
+there was a pinpoint of light on the screen. For all its beauty, the Map
+had a very useful purpose ... the registry and identification of
+asteroid claims among the miners of Mars. Each asteroid registered as a
+claim showed up as a red pinpoint; unclaimed asteroids were white. But
+even with the advances of modern astronomy only a small percentage of
+the existing asteroids were on the map, for the vast majority had never
+been plotted.
+
+Tom moved up to the Map and activated the magnifier. Carefully he
+focussed down on the section of the Asteroid Belt they had visited so
+recently. Dozens of pinpoints sprang to view, both red and white, and
+beneath each red light the claim-number neatly registered. Tom peered at
+the section, searching until he found the number of Roger Hunter's last
+claim.
+
+It was quite by itself, not a part of an asteroid cluster. He stepped up
+the magnification, peered at it closely. There were a dozen other
+pinpoints, all unclaimed, within a ten-thousand-mile radius....
+
+But near it, nothing....
+
+No hiding place.
+
+And then, suddenly, he knew the answer. He stared at the Map, his heart
+pounding in his throat. He cut the magnification, scanning a wide area.
+Then he widened the lens still further, and checked the coordinates at
+the bottom of the viewer.
+
+He knew that he was right. He _had_ to be right. But this was no wild
+dream, this was something that could be proved beyond any question of
+error.
+
+Across the room he picked up the phone to Map Control. It buzzed
+interminably; then a sleepy voice answered.
+
+"The Map," Tom managed to say. "It's recorded on time-lapse film, isn't
+it?"
+
+"'Course it is," the sleepy voice said. "Observatory has to have the
+record. One frame every hour...."
+
+"I've got to see some of the old film," Tom said.
+
+"_Now?_ It's three in the morning."
+
+"I don't need the film itself, just project it for me. There's a reader
+here."
+
+He gave the man the dates he wanted, Mars time. The man broke the
+contact, grumbling, but moments later one of the film-viewers sprang to
+life. The Map coordinates showed at the bottom of the screen.
+
+Tom stared at the filmed image ... the image of a segment of the
+Asteroid Belt the day before Roger Hunter had died.
+
+It was there. When he had looked at the Map, he had seen a single red
+pinpoint of light, Roger Hunter's asteroid, with nothing in the heavens
+anywhere near it.
+
+But on the film image taken weeks before there were two points of light.
+One was red, with Roger Hunter's claim number beneath it. The other was
+white, so close to the first that even at full magnification it was
+barely distinguishable.
+
+_But it was there._
+
+Tom's hands were trembling with excitement; he nearly dropped the phone
+receiver as he punched the buttons to ring the apartment. Greg's face
+appeared on the screen, puffy with sleep. "What's that? Thought you were
+in bed...."
+
+"You've got to get down here," Tom said.
+
+Greg blinked, waking up. "What's the matter? Where are you?"
+
+"In the Map Room. Wake Johnny up and get down here. And try to get hold
+of the Major."
+
+"You've found something," Greg said, excited now.
+
+"I've found something," Tom said. "I've found where Dad hid his
+strike ... and I know how we can find it! We've got the answer, Greg."
+
+
+
+
+14. The Missing Asteroid
+
+
+It had been a wild twelve hours since Tom Hunter's call to his brother
+from the Map Room in Sun Lake City. The Major had arrived first, still
+buttoning his shirt and wiping sleep from his eyes. Johnny and Greg came
+in on his heels. They had found Tom waiting for them, so excited he
+could hardly keep his words straight.
+
+He told them what he had found, and they wondered why they had not
+thought of it from the first moment. "We knew there had to be an
+answer," Tom said, "some place Dad could have used for a hiding place,
+some place nobody would even think to look. Dad must have realized that
+he didn't have much time. When he saw his chance, he took it."
+
+And it was pure, lucky chance. Tom showed them the section of the Map he
+had examined, with the pinpoint of light representing Roger Hunter's
+asteroid claim. Then the Map Control officer ... much more alert when he
+saw Major Briarton ... brought an armload of films up and loaded them
+into the projector. They stared at the screen, and saw the two pinpoints
+of light where one was now.
+
+"What was the date of this?" the Major asked sharply.
+
+"Two days before Dad died," Tom said. "There's quite a distance between
+them there ... but watch. One frame for every hour. Watch what happens."
+
+He began running the film, the record taken from the Map itself,
+accurate as clockwork. The white dot was moving in toward the red dot at
+a forty-degree angle. For an instant it looked as though the two were
+colliding ... and then the distance between them began to widen again.
+Slowly, hour by hour, the white dot was moving away, off the screen
+altogether....
+
+The Major looked up at Tom and slammed his fist on the chair-arm. "By
+the ten moons of Saturn...." he exploded, and then he was on his feet,
+shouting at the startled Map Control officer. "Get me Martinson down
+here, and fast. Call the port on a scrambled line and tell them to stand
+by with a ship on emergency call, with a crack interceptor pilot ready
+to go. Then get me the plotted orbits of every eccentric asteroid that's
+crossed Mars' orbit in the last two months. And double-A security on
+everything ... we don't want to let Tawney get wind of this...."
+
+Later, while they waited, they went over it to make sure that nothing
+was missing. "No wonder we couldn't spot it," the Major said. "We were
+looking for an asteroid in a standard orbit in the Belt."
+
+"But there wasn't any," Tom said. "Dad's rock was isolated, nowhere near
+any others. And we were so busy thinking of the thousands of rocks in
+normal orbits between Mars and Jupiter that we forgot that there are a
+few eccentric ones that just don't travel that way."
+
+"Like this one." The Major stared at the screen. "A long, intersecting
+orbit. It must swing out almost to Jupiter's orbit at one end, and come
+clear in to intersect Earth's orbit at the other end...."
+
+"Which means that it cuts right through the Asteroid Belt and on out
+again." Tom grinned. "Dad must have seen it coming ... must have thought
+it was on collision course for a while. But he also must have realized
+that if he could hide something on its surface as it came near, it would
+be carried clear out of the Belt altogether in a few days' time."
+
+"And if we can follow it up and intercept it...." The Major was on his
+feet, talking rapidly into the telephone. Sleep was forgotten now,
+nothing mattered but pinpointing a tiny bit of rock speeding through
+space. Within an hour the asteroid had been identified, its eccentric
+orbit plotted. The coordinates were taped into the computers of the
+waiting Patrol ship, as the preparations for launching were made.
+
+It could not be coincidence. Somewhere on the surface of that tiny
+planetoid racing in toward the Sun they knew they would find Roger
+Hunter's secret.
+
+ * * * * *
+
+Below them, as they watched, the jagged surface of the asteroid drew
+closer.
+
+It was not round ... it was far too tiny a bit of cosmic debris to have
+sufficient gravity to crush down rocks and round off ragged corners. It
+was roughly oblong in shape, and one side was sheer smooth rock surface.
+The other side was rough, bristling with jutting rock. More than
+anything else it looked like a ragged mountain top, broken off at the
+peak and hurled into space by an all-powerful hand.
+
+Slowly the scout-ship moved closer, braking with its forward jets. The
+pilot was expert. Carefully and surely he aligned the ship with the rock
+in speed and direction. In the accelleration cot Tom could feel only an
+occasional gentle tug as the power cut on and off.
+
+Then the Lieutenant said, "I think we can make a landing now, Major."
+
+"Fine. Take a scooter down first, and carry a guy line."
+
+They unstrapped, and changed into pressure suits. In the airlock they
+waited until the Lieutenant had touched the scooter down. Then Major
+Briarton nodded, and they clamped their belts to the guy line.
+
+One by one they leaped down toward the rock.
+
+From a few miles out in space, the job of searching the surface had not
+appeared difficult. From the rock itself, things looked very different.
+There was no way, from the surface, to scan large areas, and the surface
+was so rough that they had to take constant care not to damage their
+boots or rip holes in their suits. There were hundreds of crevices and
+caves, half concealed by the loose rock that crumbled under their feet
+as they moved.
+
+They spread out from the scooter for an hour of fruitless searching. Tom
+spent most of the time pulling his boots free of surface cracks and
+picking his way over heaps of jagged rock. None of them got farther than
+a hundred yards from the starting place. None of them found anything
+remarkable.
+
+"We could spend weeks covering it this way," Greg said when they met at
+the scooter again. "Why don't I take the scooter and criss-cross the
+whole surface at about fifty feet? If I spot anything, I'll yell."
+
+It seemed like a good idea. Greg strapped himself into the scooter's
+saddle, straddling the fuel tanks, using the hand jet to guide himself
+as he lifted lightly off the surface. He disappeared over the horizon of
+rock, then reappeared as he moved over the surface and back.
+
+Tom and Johnny waited with the Major. Twenty minutes later Greg brought
+the tiny craft back again. "It's no good," he said. "I've scanned the
+whole bright-side, came as close as I dared."
+
+"No sign of anything?" Johnny said.
+
+"Not a thing. The dark side looks like a sheer slab, from what my lights
+show. If we only had some idea what we were looking for...."
+
+"Maybe you weren't close enough," Tom said. "Why not drop each of us off
+to take a quarter of the bright-side and work our way in?"
+
+The others agreed. Tom waited until the Major and Johnny had been
+posted; then he hopped on the scooter behind Greg and dropped off almost
+at the line of darkness, where the sheer slab began. All of them had
+hoped that there might be a sign, something that Roger Hunter might have
+left to mark his cache, but if there was one none of them spotted it.
+Tom checked with the others by the radio in his helmet, and started
+moving back toward the center of the bright side.
+
+An hour later he was only halfway to the center, and he was nearly
+exhausted. At a dozen different spots he thought he had found a
+promising cleft in the rock, a place where something might have been
+concealed ... but exploration of the clefts proved fruitless.
+
+And now his confidence began to fail. Supposing he had been wrong? They
+knew the rock had passed very close to Roger Hunter's asteroid, the
+astronomical records proved that. But suppose Dad had not used it as his
+hiding place at all? He pulled himself around another jagged rock shelf,
+staring down at the rough asteroid surface beyond....
+
+At the base of the rock shelf, something glinted in the sunlight. He
+leaped down, and thrust his hand into a small crevice in the rock. His
+hand closed on a small metal object.
+
+It was a gun. It felt well balanced, familiar in his hand ... the
+revolver Dad had always carried in his gun case.
+
+He had to let them know. He was just snapping the speaker switch when he
+heard a growl of static in his earphones, and then Greg's voice,
+high-pitched and excited. "Over here! I think I've found something!"
+
+It took ten minutes of scrambling over the treacherous surface to reach
+Greg. Tom saw his brother tugging at a huge chunk of granite that was
+wedged into a crevice in the rock. Tom got there just as the Major and
+Johnny topped a rise on the other side and hurried down to them.
+
+The rock gave way, rolling aside, and Greg reached down into the
+crevice. Tom leaned over to help him. Between them they lifted out the
+thing that had been wedged down beneath the boulder.
+
+It was a metal cylinder, four feet long, two feet wide, and bluntly
+tapered at either end. In the sunlight it gleamed like polished silver,
+but they could see a hairline break in the metal encircling the center
+portion.
+
+They had found Roger Hunter's bonanza.
+
+ * * * * *
+
+In the cabin of the scout-ship they broke the cylinder open into two
+perfect halves. It came apart easily, a shell of paper-thin but
+remarkably strong metal, protecting the tightly packed contents.
+
+There was no question what the cylinder was, even though there was
+nothing inside that looked even slightly familiar at first examination.
+There were several hundred very tiny thin discs of metal that fit on the
+spindle of a small instrument that was packed with them. There were
+spools of film, thin as tissue but amazingly strong. Examined against
+the light in the cabin, the film seemed to carry no image at all ... but
+there was another small machine that accepted the loose end of the film,
+and a series of lenses that glowed brightly with no apparent source of
+power. There was a thick block of shiny metal covered on one side with
+almost invisible scratches....
+
+A time capsule, beyond doubt. A confusing treasure, at first glance, but
+the idea was perfectly clear. A hard shell of metal protecting the
+records collected inside....
+
+_Against what? A planetary explosion? Some sort of cosmic disaster that
+had blown a planet and its people into the fragments that now filled the
+Asteroid Belt?_
+
+At the bottom of the cylinder was a small tube of metal. They examined
+it carefully, trying to guess what it was supposed to be. At the bottom
+was a tiny stud. When they pressed it, the cylinder began to expand and
+unfold, layer upon layer of thin glistening metallic material that
+spread out into a sheet that stretched halfway across the cabin.
+
+They stared down at it. The metal seemed to have a life of its own,
+glowing and glinting, focussing light into pinpoints on its surface.
+
+It was a map.
+
+At one side, a glowing ball with a fiery corona, an unmistakeable
+symbol that any intelligent creature in the universe that was able to
+perceive it at all would recognize as a star. Around it, in clearly
+marked orbits, ten planets. The third planet had a single satellite, the
+fourth two tiny ones. The sixth eleven. The seventh planet had ten, and
+was encircled by glowing rings.
+
+But the fifth planet was broken into four parts.
+
+Beyond the tenth planet there was nothing across a vast expanse of the
+map ... but at the far side was another star symbol, this one a double
+star with four planetary bodies.
+
+They stared at the glowing map, speechless. There could be no mistaking
+the meaning of the thing that lay before them, marked in symbols that
+could mean only one thing to any intelligence that could recognize stars
+and planets.
+
+But in the center of the sheet was another symbol. It lay halfway
+between the two Solar Systems, in the depths of interstellar space. It
+was a tiny picture, a silvery sliver of light, but it too was
+unmistakeable.
+
+It could be nothing else but a Starship.
+
+ * * * * *
+
+Later, as they talked, they saw that the map had told each of them,
+individually, the same thing. "They had a star-drive," Tom said.
+"Whatever kind of creatures they were, and whatever the disaster that
+threatened their planet, they had a star-drive to take them out of the
+Solar System to another star."
+
+"But why leave a record?" Greg wanted to know. "If nobody was here to
+use it...."
+
+"Maybe for the same reason that Earthmen bury time capsules with records
+of their civilization," Major Briarton said. "I'd guess that the records
+here will tell, when they have been studied and deciphered. Perhaps
+there was already some sign of intelligent life developing elsewhere in
+the Solar System. Perhaps they hoped that some of their own people would
+survive. But they had a star-drive, so some of them must have escaped.
+And with the record here...."
+
+"We may be able to follow them," Greg said.
+
+"If we can decipher the record," Johnny Coombs said. "But we don't have
+any clue to their language."
+
+"Did you have any trouble understanding what the map had to say?" the
+Major said quietly.
+
+"No...."
+
+"I don't think the rest will be much more difficult. They were
+intelligent creatures. The record will be understandable, all right." He
+started to fold the map back into a tube again. "Maybe Roger Hunter
+tried to use the film projector. We'll never know. But he must have
+realized that he had discovered the secret of a star-drive. He realized
+that the United Nations were the ones to explore it and use it, and he
+gave his life to keep it out of the hands of Tawney and his men...."
+
+"A pity," a cold voice said close behind them, "that he didn't succeed,
+after all."
+
+They whirled. In the hatchway to the after-cabin, Merrill Tawney was
+standing, with a smile on his lips and a Markheim stunner trained
+directly on Major Briarton's chest.
+
+
+
+
+15. The Final Move
+
+
+"I realize I'm much earlier than you expected, Major. You did a very
+neat job of camouflaging your takeoff ... we were almost fooled ... and
+no doubt the dummy ship you sent off later got full fanfare. I suppose
+there will be a dozen Patrol ships converging on this spot in a few
+hours, expecting to surprise a Jupiter Equilateral ship making a
+desperate attempt to hijack your little treasure here."
+
+The little fat man laughed cheerfully. "Unfortunately for you," he
+added, "we have many friends on Mars ... including a man in the Map
+room ... and I'm afraid your little trap isn't going to work after all."
+
+The Major's face was gray. "How did you get here?"
+
+"By hitch-hiking. How else? Most uncomfortable, back there, even with a
+pile of pressure suits for padding, but your pilot was really very
+skillful."
+
+Johnny Coombs turned on the Major. "What does he mean, a trap? I don't
+get this...."
+
+The Major sighed wearily. "I had to try to force his hand. Even if we
+found what we were looking for, we had no case that could stand up
+against them. We needed _proof_ ... and I thought that with this as bait
+we could trap them. He's right about the Patrol ships ... but they won't
+be near for hours."
+
+"And that will be a little late to help," Tawney said pleasantly.
+
+The Major glared at him. "Maybe so ... but you've gone too far this
+time. This is an official U.N. ship. You'll never be able to go back to
+Mars."
+
+"Really?" the fat man said. "And why not? Officially I'm on Mars right
+now, with plenty of people to swear to the fact." He chuckled. "You seem
+to forget that little matter of proof, Major. When your Patrol ships
+find a gutted ship and five corpses, they may suspect that something
+more than an accident was involved, but what can they prove? Nothing
+more than they could prove in the case of Roger Hunter's accident.
+Scout-ships have been known to explode before."
+
+He ran his hand over the metal cylinder. "And as for this ... it's
+really a surprise. Of course when we failed to find any evidence of
+mining activity, we were certain that Roger Hunter's bonanza was
+something more than a vein of ore, but _this_! You can be certain that
+we will exploit the secret of a star-drive to the very fullest."
+
+"How do you think you can get away with it?" the Major said. "Turning up
+with something like that right after a whole series of suspicious
+accidents in space?"
+
+"Oh, we aren't as impatient as some people. We wouldn't be so foolish as
+to break the news now. Five years from now, maybe ten years, one of our
+orbit-ships will happen upon a silvery capsule on one of our asteroid
+claims, that's all. I wouldn't be surprised if a non-company observer
+might be on board at the time, maybe even a visiting Senator from Earth.
+For something this big, we can afford to be patient."
+
+There was silence in the little scout-ship cabin. The end seemed
+inevitable. This was a desperate move on Tawney's part. He was gambling
+everything on it; he would not take the chance of letting any of them
+return to Mars or anywhere else to testify.
+
+Greg caught Tom's eye, saw the hopelessness on his brother's face. He
+clenched his fists angrily at his side. If it were not for Tom, Dad's
+bonanza might have gone on circling the sun for centuries, maybe
+forever, wedged in its hiding place on the rocky surface of the
+eccentric asteroid.
+
+But it had been found. Earth needed a star-drive badly; a few more
+years, and the need would be desperate. And if a group of power-hungry
+men could control a star-drive and hold it for profit, they could
+blackmail an entire planet for centuries, and build an empire in space
+that could never be broken.
+
+He knew that it must not happen that way. Dad had died to prevent it.
+Now it was up to them.
+
+ * * * * *
+
+Greg glanced quickly around the cabin, searching for some way out,
+something that might give them a chance. His eyes stopped on the control
+panel, and he sucked in his breath, his heart pounding. A
+possibility....
+
+It would require a swift, sure move, and someone to help, someone with
+fast reflexes. It was dangerous; they might all be killed. But if his
+training at Star-jump was good for anything, it might work.
+
+He caught Johnny Coombs' eye, winked cautiously. A frown creased
+Johnny's forehead. He shot a quick look at Tawney, then lowered his
+eyelid a fraction of an inch. Greg could see the muscles of his
+shoulders tightening.
+
+Greg took quick stock of the cabin again. Then he took a deep breath and
+bellowed, "Johnny ... _duck_!"
+
+Almost by reflex, Johnny Coombs hurled himself to the floor. Tawney
+swung the gun around. There was an ugly ripping sound as the stunner
+fired ... but Greg was moving by then. In two bounds he was at the
+control panel. He hooked an arm around a shock bar, and slammed the
+drive switch on full.
+
+There was a roar from below as the engines fired. Greg felt a jolt of
+pain as the accelleration jerked at his arm. Tom and the Major were
+slammed back against a bulkhead, then fell in a heap on top of Johnny
+and the Lieutenant as the awful force of the accelleration dragged them
+back. Across the cabin Tawney sprawled on the floor. The stunner flew
+from his hand and crashed against the rear bulkhead.
+
+On the panel Greg could see the accelleration gauge climbing
+swiftly ... past four g's, up to five, to six. The ship was moving
+wildly; there was no pilot, no course.
+
+With all the strength he could muster Greg tightened his arm on the
+shock bar, lifting his other arm slowly toward the cut-off switch. He
+had spent many hours in the accelleration centrifuge at Star-Jump,
+learning to withstand and handle the enormous forces of accelleration
+for brief periods, but the needle was still climbing and he knew he
+could not hold on long. His fingers touched the control panel. He
+strained, inching them up toward the switch....
+
+His fingers closed on the stud, and he pulled. The engine roar ceased.
+On the floor behind him Tawney moved sluggishly, trying to sit up. Blood
+was dripping from his nose. He was still too stunned to know what had
+happened.
+
+Greg leaped across the room, caught up the stunner, and then sank to the
+floor panting. "All right," he said as his breath came back, "that's
+all. Your ship may have trouble finding us now ... but I bet our pilot
+can get us back to Mars."
+
+ * * * * *
+
+When they left the Sun Lake City infirmary it was almost noon, and the
+red sun was gleaming down from overhead. Walking slowly, the Hunter
+twins moved along the surface street toward the U.N. building.
+
+"He'll recover without any trouble," the doctor had assured them. "He
+caught the stunner beam in the shoulder, and it will be a while before
+he can use it, but Johnny Coombs will be hard to keep down."
+
+They had promised Johnny to return later. They had had check-ups
+themselves. Both Tom's eyes were surrounded by purple splotches, and his
+broken left arm was in a sling. Greg's arms and legs were so stiff he
+could hardly move them. The Major and the Lieutenant had been sore but
+uninjured.
+
+Now the boys walked without talking. Already a U.N. linguist was at work
+on the record tapes from the metal cylinder, and a mathematician was
+doing a preliminary survey on the math symbols on the metal block.
+
+"I hope there's no trouble reading them," Greg said.
+
+"There won't be. It'll take time, but the records are decipherable. And
+Dr. Raymond was certain that the engineering can be figured out. Earth
+is going to get her star-ship, all right."
+
+"And we've got work to do."
+
+"You mean the trial? I guess. The Major says that Jupiter Equilateral is
+trying to pin the whole thing on Tawney now. They won't get away with
+it, but it may be nasty just the same."
+
+"Well, one thing's sure ... there'll be some changes made, with the U.N.
+moving out into the Belt," Greg said.
+
+Somewhere in the distance the twins heard the rumble of engines. They
+stopped and watched as a great silvery cargo ship lifted from the space
+port and headed up into the dark blue sky. They watched it until it
+disappeared from sight.
+
+They were both thinking the same thing.
+
+An Earth-bound ship, powerful and beautiful, but limited now to the sun
+and nine planets, unable to reach farther out.
+
+But someday soon a different kind of ship would rise.

+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, is critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at https://www.pglaf.org.
+
+
+Section 3. Information about the Project Gutenberg Literary Archive
+Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the

+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit https://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including including checks, online payments and credit card
+donations. To donate, please visit: https://pglaf.org/donate
+
+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart was the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ https://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
