OUT OF THE IRON WOMB! By POUL ANDERSON Behind a pale Venusian mask lay hidden the arch-humanist, the anti-tech killer ... one of Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] 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 blackness in the loom of shadows its teeth ate raggedly across the Milky Way. Before him, a tumbled igneous wilderness slanted crazily gravity was feeble enough. The stars blazed with a cruel wintry brilliance, over him, around Bo Jonsson's tongue was dry and thick in his mouth. He wanted to There are numerous reasons for basing on the Trojan asteroids, but the main one can be given in a single word: stability. They stay put genuinely private enterprise: the prospector, the mine owner, the 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. Bo Jonsson into going there for a final spree before checkoff and departure. "Nothing to compare," he insisted. "Every place else is getting too fantangling civilized, except Venus, and I don't enjoy Venus." nervous movements and dipped accent of that roaring commercial metropolis. He affected the latest styles, brilliant colors in the 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 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, with amiable blue eyes in a battered brown face, he did not consider himself bright, and always wanted to learn. synthetic alcohol, and a dash of caramel they have the gall to label whiskey and charge for!" "Everything's expensive here," said Bo mildly. "That's why so few and we've got to fortify ourselves for the trip. A bottle, a battle, and a wench is what I need. Most especially the wench, because I don't think the eminent Dr. McKittrick is gonna be interested in sociability, "Because I am one at heart. Look, Bo, why don't you get over that knowing more math and physical science than the average professor on Earth. So you had to work your way through the Academy and never had a chance to fan yourself with a lily white hand while somebody tootled "I don't, Johnny," said Bo. "I'll just nurse a beer." It wasn't morals Bo chuckled. The Company consisted of (a) the else but she went wherever there was cargo or people to be moved. Her margin of profit was not great in spite of the charges, for a Bo shook his head and watched his partner move off, swift in the puny Bo sighed, feeling a bit lonesome. If he wasn't going to make a night 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. As he neared, he caught words: "—my girl, dammit." "Like hell I am!" said the girl. "I never saw you before—" A spaceman, that. Knows how to handle himself in low-gee. It was the only clear thought which ran in the sudden storm of Bo's head. Bo had seen death before. That needle wasn't anesthetic, it was poison. tortured swirl of crystallization patterns in the smooth bareness. No place to hide had often stood on winter nights, back in Sweden, and seen its immense sprawl across the weird flicker of aurora He moved with flat low-gee bounds. Besides the danger of springing off the asteroid entirely, there was its low acceleration to keep a man Bo stood unmoving an instant, fighting the impulse to leap away. He was with an ultimate cold. Around him, world and stars rippled as if seen through heat, through fever. He hung on the edge of creation by his fingertips, while chaos shouted beneath. might get too tired at the critical moments. Bo knew he wouldn't be Bo didn't care the first day. He had taken Johnny out to Helmet Hill "Hadn't you heard?" asked Bo. He found it hard to believe she could Bo shrugged, not caring much. "I'll circulate an ad if you want, but—" "Do so, please. Let me know." She switched off. Bo sat for a moment thinking about her. Valeria McKittrick was worth considering. She wasn't beautiful in any conventional sense but she was tall and well built there were good lines in the strong high boned face, and her hair was a cataract of spectacular red. And brains, too ... you didn't get to be a physicist with the Union's radiation labs for nothing. He knew she was still young, and that she had been on Achilles for about a year working on some special project and was now She was human enough, had been to most of the officers' parties and danced and laughed and flirted mildly, but even the dullest rockhound gossip knew she was too lost in her work to do more. Out here a woman was rare, and a virtuous woman unheard-of as a result, unknown to herself, Dr. McKittrick's fame had spread through more thousands of people and millions of miles than her professional achievements were ever likely to reach. Since coming here, on commission from the Lunar lab, to bring her home, Bo Jonsson had given her an occasional wistful thought. He liked intelligent women, and he was getting tired of rootlessness. But of course it would be a catastrophe if he fell in love with her because she wouldn't look twice at a big dumb slob like him. He had sweated out a couple of similar affairs in the past and didn't want to go through another. Lundgard down to the desk. It was a lean, muscular face under close cropped brown hair which appeared in the screen. Lundgard was a tall and supple man, somehow "Oh, yes. Are you looking for a spaceman? I heard your ad and I'm available." Bo felt his mouth gape open. "Huh? I never thought—" "How does a qualified spaceman happen to be marooned?" Bo nodded, for every spaceman knows exactly what every spaceship is while she lay in orbit, she had somehow lost a few hundred pounds of reaction-mass water from a cracked gasket. Why the accident should have occurred, nobody knew ... spacemen Bo had heard of it in the course of Bo understood that kind of loyalty. You couldn't travel space without all told." "Against six months here?" Lundgard laughed it emphasized the bright charm of his manner. "Sunblaze. I'll work for free." hands on it. "Call me Bo. It really is my name ... Swedish." Bo went at his share of the job doggedly, checking and re-checking Bo relaxed against the thrust, thinking of Achilles falling away behind Bo clamped his teeth together, as if he would grip consciousness in Bo's mind wavered back toward life. He opened the valves wide on his felt withered and flayed, but the rasp of air through it was like being born again. 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
