<passage>:
The most dangerous is not the outlawed murderer, who only slays men, but the rebellious philosopher: for he destroys worlds. Darkness and the chill glitter of stars. Bo Jonsson crouched on a whirling speck of stone and waited for the man who was coming to kill him. with him, hunting him down. Bo Jonsson looked at the wrench in his hand. It was long and massive, it would have been heavy on Earth, but it was hardly enough to unscrew the stars and reset the machinery of a universe gone awry. He smiled stiffly at the thought. He wanted to laugh too, but checked himself for fear he wouldn't be able to stop. Let's face it , he told himself. miles, probably more if you allowed for the rough surface. He could skulk around, hide ... and suffocate when his tanked air gave out. He had to be a hunter, too, and track down the other man, before he died. And if he found his enemy, he would probably die anyway. a couple of pounds here. It was ghostly, this soundless progress over fields which had never known life. It was like being dead already. Bo Jonsson's tongue was dry and thick in his mouth. He wanted to find his enemy and give up, buy existence at whatever price it would command. But he couldn't do that. Even if the other man let him do it, rockhound dreaming of the day when his stake is big enough for him to start out on his own—a race of individualists, rough and noisy and jealous, but living under iron rules of hospitality and rescue. flowing tunic and slacks, a beret cocked on his sleek head. But somehow he didn't grate on Bo, they had been partners for several years now. They pushed through a milling crowd at the bar, rockhounds who watched one of Achilles' three live ecdysiasts with hungry eyes, and by some miracle found an empty booth. Bo squeezed his bulk into one side of the cubicle while Johnny, squinting through a reeking smoke-haze, dialed drinks. Bo was larger and heavier than most spacemen—he'd never have gotten his certificate before the ion drive came in—and was usually content to let others talk while he listened. A placid blond giant, "Everything's expensive here," said Bo mildly. "That's why so few rockhounds get rich. They make a lot of money, but they have to spend it just as fast to stay alive." Bo kept on sipping slowly. "Johnny," he said, raising his voice to cut "Because I am one at heart. Look, Bo, why don't you get over that inferiority complex of yours? A man can't run a spaceship without "If we want some women we'd better make our reservations now." "I don't, Johnny," said Bo. "I'll just nurse a beer." It wasn't morals so much as fastidiousness he'd wait till they hit Luna. Bo chuckled. The Company consisted of (a) the Sirius (b) her crew, but it was also more effective in low-gee. "'Scuse me," he said. "I see a target. Sure you don't want me to ask if she has a friend?" Bo shook his head and watched his partner move off, swift in the puny gravity—the Last Chance didn't centrifuge like some of the tommicker places downtown. It was hard to push through the crowd without weight her, but Johnny had The Touch. He'd be bringing her back here in a few minutes. Bo sighed, feeling a bit lonesome. If he wasn't going to make a night of it, there was no point in drinking heavily. He had to make the final inspection of the ship tomorrow, and grudged the cost of anti-hangover There was a tall black haired man, Venusian to judge by his kilts, arguing with Johnny. His face was ugly with anger. Johnny made some reply. Bo heaved up his form and strode toward the discussion, casually picking up anyone in the way and setting him aside. Johnny liked a fight, but this Venusian was big. "Run along and play, son," said Johnny. "Or do you want me to change lifted the jagged end. There was the noise of a fist meeting flesh. Bo had seen death before. That needle wasn't anesthetic, it was poison. He knelt in the riot with Johnny's body in his arms. II Bo stood unmoving an instant, fighting the impulse to leap away. He was a spaceman, not a rockhound he wasn't used to this environment, and if or three are required for non-military craft. This is not only an emergency reserve, but a preventive of emergencies, for one man alone might get too tired at the critical moments. Bo knew he wouldn't be allowed to leave Achilles without a certified partner, and unemployed Bo didn't care the first day. He had taken Johnny out to Helmet Hill and laid him in the barren ground to wait, unchanging now, till Judgement Day. He felt empty then, drained of grief and hope alike, his main thought a dull dread of having to tell Johnny's father when his comforting hand would only break the old man's back. Old Malone had given six sons to space, Johnny was the last "Johnny's dead. We can't leave." had one more man aboard than really required, it was cheaper to leave him behind during my watch, and even if nobody blamed me I couldn't help feeling guilty." Bo understood that kind of loyalty. You couldn't travel space without men who had it. "The Company beamed a message: I'd stay here till their schedule modified, no trip ever turned out just as predicted, but that could be done when needed with a slipstick and the little ship's calculator. Bo went at his share of the job doggedly, checking and re-checking before giving the problem to the machine Lundgard breezed through it and spent his time while waiting for Bo in swapping dirty limericks waited. At the proper time, acceleration jammed them back in a thunder of rockets. Bo relaxed against the thrust, thinking of Achilles falling away behind them. "So long," he whispered. "So long, Johnny." III In another minute, he would be knotted and screaming from the bends, and a couple of minutes later he would be dead. Bo clamped his teeth together, as if he would grip consciousness in his jaws. His hands felt cold and heavy, the hands of a stranger, as he fumbled for the supply pouch. It seemed to recede from him, down a The plastic patch stuck to his metal gauntlet. He peeled it off, trying not to howl with the fury ripping in his nerves. His body was slow, inert, a thing to fight. There was no more feeling in his back, was he dead already? the sucking vacuum. The patch bellied out from internal air pressure, straining to break loose and kill him. Bo's mind wavered back toward life. He opened the valves wide on his tanks, and his thermostatic capacitors pumped heat back into him. For a long time he lay there, only lungs and heart had motion. His throat Born, spewed out of an iron womb into a hollowness of stars and cold, to lie on naked rock while the enemy hunted him. Bo shuddered and wanted to scream again. Slowly he groped back toward awareness. His frostbitten back tingled have spent most of its force punching through the armor, caromed off the inside, scratched his ribs, and fallen dead. Next time he probably gauges. This had cost him a lot of air. There was only about three hours worth left. Lundgard could kill him simply by waiting. It would be easy to die. He lay on his back, staring up at the stars
