  The ship was a dim spark, climbing up the long slant toward the ecliptic. Up there, Isar and her daughters had deliveries to make and cargoes to take on at Pluto. Gron, their city, had sent them down this long detour to make a survey. The planetoid was now approaching the sun, on its eccentric cometary orbit, for the first time in twenty thousand years. Once here, it would be folly not to surface-mine the planetoid for whatever it might be worth. One child could do. that, and survey the planetoid as well.

  Alone, Zael turned impassively to the six-wheeled crawler. She might have rested awhile in the bubble house, but she had some hours of suit time left, and there was no need to waste it. She lifted herself easily against the slight gravity into the cab; turned on the lights and started the motor.

  The spidery vehicle crawled ahead on its six individually sprung wheels. The terrain was astonishingly broken; giant spires and craters alternated with ravines and with fissures, some of them forty feet wide and thousands of feet deep. The planetoid’s orbit passed near the sun, according to the astronomers, perhaps nearer than the orbit of Venus. Even now, the temperature of the rocks was a few degrees above absolute zero. This was a cold beyond anything Zael had ever experienced. She could feel it drawing at her feet through the long insulator spikes of her boot soles. The molecules of every stone were slowed to stillness; the whole world was one frozen yawn of hunger.

  But once it had been a hot world. The record was here. At every periheiion passage, the rocks must have split, again and again, to make this nightmare of tumbled stone.

  The surface gravitation was only one tenth G, almost like free-fall; the light, puffy-wheeled vehicle crawled easily up slopes within a few degrees of the vertical. Where it could not climb, it went around. Narrow fissures were bridged by the crawler’s extensible legs; when she came to larger ones, Zael fired a harpoon which soared across the gap and embedded itself on the other side. The crawler edged forward, toppled and swung at the end of its cable; but while the slight gravity drew it toward the far side of the fissure, the crawler’s winch motor was reeling in the cable. It arrived with a faint jar at the opposite side and, without pausing, inched up and over.

  Sitting erect behind her instruments, Zael was charting the mineral deposits she passed over, It was a satisfaction to her to find they were rich enough to repay surface mining. The cities could make almost anything out of anything, but they needed a primary source: they had to have metals.

  Methodically, she spiralled outward from the bubble house, charting a region no more than thirty miles in diameter. In the unpressurized crawler, it was not feasible to take in a larger area.

  Labouring alone, hour after hour under the unchanging sky, she identified the richest lodes, marked them and established routes. Between times, she ate and slept in the bubble house, tended her necessary plants, serviced her equipment. Out of her armour, she was slender and spare, quick in her movements, with the harsh, thin-lipped comeliness of her people.

  When her chart was made, she rode out again. At each marked spot, she dropped two widely separated poles. Self-embedding, each pair generated a current which ionized the metals or metallic salts and would slowly deposit pure metal around the cathode, Eventually the concentration would be such that the metal could be sawed out in blocks for convenient loading.

  Only then did she turn her attention to the traces of shaped metal that clung here and there to the rocks. They were fragments, for the most part, such as were commonly found on cold satellites like Mimas and Titan, and occasionally on stony asteroids. It was not a matter of any importance; it simply meant that the planetoid had been inhabited or colonized at one time by the same pre-human civilization that had left its traces throughout the solar system.

  But she had been sent to see whatever was to be seen. Her real work was almost done; she conscientiously examined the traces, photographed some, took others for specimens. She beamed regular radio reports to Gron; sometimes, five days later, there would be a curt acknowledgment waiting for her in the printer; sometimes not. Regularly she made the rounds of the poles, testing the concentration of metal. She was ready to replace any faulty poles she might find, but the occasion did not arise; Gron equipment seldom failed.

  The planetoid hung in its millennial arc. The sky imperceptibly turned around it. The moving spark that was the escape shell traced its path, again and again. Zael grew restless and took the crawler on wider explorations. Deep in the cold crannies of the mountains, she found some metal constructions that were not mere fragments but complete works—dwellings or machines. The dwellings, if they were that, were made for some creature smaller than man; the doorways were ovals not more than a foot across. She dutifully radioed this information back to Gron and received the usual acknowledgment.

  Then, one day the printer came to life out of season. The message read: I AM COMING, ISAR.

  The ship would be three months slower than the message. Zael kept her calendar, rode her rounds, her starlit face impassive. Above her the escape shell, unneeded now, made its monotonous passage over and over. Zael was tracing the remnants of a complex of surface structures that had miraculously survived, some half buried, others naked to the stars. She found where they led, in a crater only forty miles from her base, a week before the ship was due.

  In the crater was a heavily reinforced globe of metal, dented and scarred, but not smashed. As Zael’s light shone steadily on it, a sudden puff of vapour went out; the globe seemed to haze over briefly. Zael peered, interested: the minute warmth of the light beam must have thawed some film of frozen gas.

  Then it happened again, and this time she could see distinctly: the jet escaped from a thin, dark seam that had not been there before.

  The seam widened as she watched. The globe was splitting. In the narrow gap between the two halves, something moved. Startled, Zael threw the crawler into reverse. The cab lights dipped as the crawler retreated up-slope. In the dimness outside the light beams, she saw the globe expanding still more. There was an ambiguous motion between the barely visible halves of the globe, and she wished she had not taken the light away.

  The crawler was tilting sidewise up a steep, broken slab of rock. Zael turned downward, still backing at a sharp angle. The light swung away from the globe altogether, then came back to it as she levelled out.

  The two halves of the globe had separated completely. In the middle, something jerked as the light struck it. She could see nothing but a thick, gleaming coil of metal. While she hesitated, there was new motion between the halves of the globe. Something gleamed briefly; there was a short ground shock; and then something struck the cab a hard, resonant blow. The lights whirled bewilderingly and went out.

  In the darkness, the cab was tipping. Zael clutched at the controls, but she was too slow. The crawler went over on its back.

  Zael felt herself being flung out of the cab. As she rolled over, ears ringing, her first and sharpest impression was of the cold that struck through her armour at gauntlet and knee. She scrambled up quickly to a kneeling position, supporting herself on the brushlike spiked soles of her boots.

  Even the brief contact had made her fingers smart with cold. She searched automatically for the crawler, which meant safety and warmth. She saw it smashed on the mountainside. Even so, her instinct drew her toward it, but she had hardly taken a first step before the wrecked machine leaped again and rolled another dozen yards down the slope.

  She turned now, for the first time fully realizing that something down there was shooting at the crawler. Then she saw a glimmering shape that writhed up toward the wrecked machine. Her helmet light was not turned on; she crouched still and felt two grinding, metallic shocks transmitted through the rock.

  The moving thing appeared again on the other side of the crawler, vanished inside, and after a long time came out again. Zael caught a glimpse of a narrow head upraised, and two red eyes gleaming. The head dropped; the sinuous form glided down into a ravine, coming toward her. Her only thought was to get away. Sh
e scrambled up in the dark, circled a spire. She saw the gleaming head upraised farther down, among a tangle of boulders, and went at a headlong, dangerous run across the slope to the wrecked crawler.

  The control board was ruined, levers bent off or flattened down, dials smashed. She straightened to look at the engine and transmission, but saw at once that it was no use; the heavy drive shaft was bent out of true. The crawler would never run again without shop repairs.

  Down in the bowl, she caught sight of the silvery shape casting along the edge of a fissure. Keeping it in view, she examined her suit and instruments all over. As far as she could tell, the suit was tight, her oxygen tanks and recirculation system undamaged.

  She was thinking coldly and clearly as she looked at the split globe, gaping empty under the stars. The thing must have been coiled in there, inert, for thousands of years. Perhaps there had been a light-sensitive device in the globe, designed to open it when the planetoid approached the sun again. But her light had broken the globe prematurely; the thing inside was awake before its time. What was it, and what would it do, now that it was alive again?

  Whatever happened, her first duty was to warn the ship. She turned on the broadcast transmitter in her suit; its range was small, but now that the ship was so near, there was a chance.

  She waited long minutes, but no answer came. From where she stood, the sun was not visible; one of the high crags must be blocking her transmission.

  The loss of the crawler had been a disaster. She was alone and afoot, forty miles across an impassable terrain from the bubble house. Her chances of survival now, she knew, were very small.

  Still, to save herself now, without finding out more about the thing, would be less than her duty. Zaellooked doubtfully down at the empty globe in the starlight. The way between was broken and dangerous; she would have to go slowly, for fear of attracting the thing if she used a light.

  She started down nevertheless, picking her way carefully among the tumbled stones. Several times she leaped fissures too long to by-pass. When she was halfway down the slope, she saw movement, and froze. The thing writhed into view over a broken ridge—she saw the triangular head again, and a waving ruff of tentacles—and then disappeared inside the open globe.

  Zael moved cautiously nearer, circling to get a view directly into the gap. After a few moments the thing emerged again, curiously stiff and thick-looking. On a level place outside the globe, it separated into two parts, and she saw now that one was the thing itself, the other a rigid metal framework, narrow and perhaps ten feet long. The thing retreated inside the globe again. When it came out, it was burdened with a bulbous mechanism which it fitted on somehow to one end of the framework. It continued working for some time, using the tentacle-like jointed members that sprouted from just behind its head. Then it returned to the globe, and this time came out with two large cubical objects. These it began to attach to the opposite end of the framework, connecting them by a series of tubes to the bulbous mechanism.

  For the first time, the suspicion entered her mind that the thing was building a spacecraft. Nothing could look less like a conventional ship, to be sure: there was no hull, nothing but a narrow shaft on which the thing could lie, the bulbous object which might be an engine, and the two big containers for reaction mass. Abruptly, she was certain. She had no Geiger with her—it was back in the crawler—but she felt sure there must be radio actives in the bulbous mechanism—a micropile, unshielded, for a spaceship without a hull! It would kill any living creature that rode on it—but what creature of flesh and blood could survive for twenty thousand years on this airless planetoid, at close to absolute zero?

  She stood gravely still. Like all her people, she had seen the evidences of an eons-old war among the cold planetoids. Some thought the war had ended with the deliberate destruction of the fourth planet, the one which had formerly occupied the place of the asteroids. A bitter war, that one must have been; and now Zael thought she could understand why. If one side had been humanlike, and the other like this thing, then neither could rest until it had wiped out the other. And if this thing were now to escape, and perhaps breed more of its kind…

  Zael inched forward, making her way from stone to stone, moving only when the thing was out of sight. The alien had finished attaching several small ambiguous objects to the front of the frame. It went back inside the globe. To Zael, the structure looked almost complete. It did not seem possible to encumber it any more and still leave space for the rider.

  Her heart was thudding. She left her concealment and went forward in a clumsy tiptoe pace that was faster than leaping. When she was almost in reach of the framework, the thing came out of the open globe. It glided toward her, enormous in the starlight, with its metal head rearing high.

  Out of pure instinct she hit the light switch. The helmet beams flared: she had an instant’s glimpse of skeletal metal ribs and gleaming jaws. Then the thing was thrashing away from her into the darkness. For a moment more she was stunned. She thought, it can’t stand light! And she scrambled forward desperately into the globe.

  The thing was coiled there, hiding. When the light struck it, it hurled itself out the other side. Zael pursued again, and caught it once more on the far side of the low ridge. It dived into a ravine and was gone.

  She turned back. The framework lay on the rock where it had been left. Zael picked it up tentatively. It had more mass than she had expected, but she was able to swing it at arm’s length until it gained a respectable speed. She dashed it against the nearest stone; the impact numbed her fingers. The framework leaped free, slid to rest on the stone. The two containers were detached: the bulbous mechanism was bent away from the frame. She picked it up again, and again swung it hard against the rock. The frame bent and buckled; small pieces came loose. She swung it again, and again, until the frame broke and the bulbous part came free.

  The alien thing was not in sight. Zael carried the pieces of the framework to the nearest fissure and dropped them in. In her helmet beams, they drifted silently down and were gone.

  She returned to the globe. The creature was still nowhere to be seen. She examined the interior: it was full of oddly shaped partitions and of machines, most too large to be moved, some that were detached and portable. She could not with certainty identify any of them as weapons. To be safe, she took all the movable objects and dropped them after the framework.

  She had done all she could, and perhaps more than was prudent. Her task now was to survive—to get back to the bubble house, call the escape shell down, and get away.

  She turned back up the slope, past the wrecked crawler, retracing her route until she came to the crater wall.

  The crags loomed over her, hundreds of feet above her head, and so sheer that when she tried to climb them, even her momentum would not keep her upright; she began to topple back and had to dance her way slowly down again to firmer footing.

  She made the full circuit of the crater before she was convinced; there was no way out.

  She was sweating under the armour: a bad beginning. The ragged tops of the mountains seemed to bend forward, peering down at her mockingly. She stood still to calm herself, took a salt pill and a sip of water from the dispenser in her helmet. The indicators showed that she had less than five hours of air left. It was little enough. She had to get out.

  She chose what seemed to be the easiest slope within reach. She went up with a rush. When her momentum began to fall, she used her hands. The cold bit through her gauntlets like needles of fire. The slightest contact was painful; to grasp firmly became an agony. She was within yards of the top when her fingers began to grow numb. She clawed upward furiously, but her fingers refused to grip; her hands slid uselessly away from the rock.

  She was falling. She toppled slowly down the slope she had climbed with so much pain; caught herself with an effort and came to rest, shaken and trembling, at the bottom.

  Cold despair settled at her heart. She was young; she had no taste for death, even for a
quick and clean one. To die slowly, gasping for air in a foul suit, or bleeding out her warmth against the stone, would be horrible.

  Out across the crater floor, she saw a dim movement in the starlight. It was the alien thing; what could it be doing, now that she had destroyed its means of escape? The thought came to her slowly that perhaps it could not get out of the crater, either. After a moment, hesitantly, she went down the slope toward it.

  Halfway down, she remembered to turn off her suit lights so as not to drive it away. The crater floor was crisscrossed with innumerable fissures. As she came nearer, she saw that the split sphere was surrounded by them on all sides. Down at one end of this long, irregular island of rock, the alien was throwing itself back and forth.

  It turned to face her as she leaped the last gap. She could see its red eyes gleaming in the darkness, and the circle of thin, jointed arms that formed a collar behind its head. As she approached, the head reared higher, and the jaws gaped.

  The sight of the thing, so near, filled her with a cold loathing she had never experienced before. It was not only that the creature was metal, and alive; it was some radiance of evil that seemed to reach her directly from the thing, as if to say, I am the death of all you love.

  The blind, red eyes stared with implacable hatred. How could she make it understand?

  The body of the thing was sinuous and strong; its jointed arms could grasp and hold. It was made for climbing, but not for jumping.

  Abruptly, her loathing for the alien was more than she could master. She turned and jumped the chasm again. On the far side, she looked back. The alien was swaying high, with more than half its length raised from the rock. She saw now that there was another cluster of gripping members at its tail. The thing glided forward to the very edge of the fissure and swayed upright again, jaws agape, eyes glaring.

  They had nothing in common but hatred—and fear. Staring across at the alien. Zael realized that it must be as afraid as she. Metal though it was, it could not live for ever without warmth. She had broken its machines, and now, like her, it was trapped. But how could she make it understand?
