He crossed a patch of ground that looked exactly like any other patch. But as the robot thundered over it, the ground gave way. Perceveral had calculated it carefully. The trap, which held under his weight, yielded at once under the robot’s bulk.
The robot thrashed for a handhold. Dirt trickled through his fingers and he slid into the trap that Perceveral had dug—a pit with sloping sides that came together like a great funnel, designed to keep the robot immovably wedged at the bottom.
The robot, however, flung both his legs wide, almost at right angles to his body. His joints creaked as his heels bit into the sloping sides; they sagged under his weight, but held. He was able to stop himself before reaching the bottom, with both legs stiffly outspread and pressed into the soft dirt.
The robot’s hand gouged deep handholds in the dirt. One leg retracted and found a foothold; then the other. Slowly the robot extricated himself, and Perceveral started running again.
His breath came short and hard now and he was getting a stitch in his side. The robot gained more easily, and Perceveral had to strain to stay ahead.
He had counted on those two traps. Now there was just one more left. A very good one, but risky to use.
Perceveral forced himself to concentrate in spite of a growing dizziness. The last trap had to be calculated carefully. He passed a stone marked in white and switched off his flashlight. He began counting strides, slowing until the robot was directly behind him, his fingers inches from his neck.
Eighteen-nineteen-twenty!
On the twentieth step, Perceveral flung himself headfirst into the darkness. For seconds, he seemed to be floating in the air. Then he struck water in a flat, shallow dive, surfaced and waited.
The robot had been too close behind to stop. There was a tremendous splash as he hit the surface of the underground lake; a sound of furious splashing; and, finally, the sound of bubbles as the heavy robot sank beneath the surface.
When he heard that, Perceveral struck out for the opposite shore. He made it and pulled himself out of the icy water. For minutes, he lay shuddering on the slimy rocks. Then he forced himself to climb further ashore on hands and knees, to a cache where he had stored firewood, matches, whisky, blankets and clothes.
During the next hours Perceveral dried himself, changed clothes and built a small fire. He ate and drank and watched the still surface of the underground lake. Days ago, he had tested with a hundred-foot line and had found no bottom. Perhaps the lake was bottomless. More likely it fed into a swift-flowing underwater river that would pull the robot along for weeks and months. Perhaps…
He heard a faint sound in the water and trained his flashlight in its direction. The robot’s head appeared, and then his shoulders and torso emerged.
The lake was very evidently not bottomless. The robot must have walked across the bottom and climbed the steep slope on the opposite side.
The robot began to climb the slimy rocks near shore. Perceveral wearily pulled himself to his feet and broke into a run.
His last trap had failed him and his neurosis was closing in for the kill. Perceveral headed toward a tunnel exit. He wanted the end to come in sunlight.
At a jolting dogtrot, Perceveral led the robot out of the tunnels toward a steep mountain slope. His breath felt like fire in his throat and his stomach muscles were knotted painfully. He ran with his eyes half closed, dizzy from fatigue.
His traps had failed. Why hadn’t he realized the certainty of their failure earlier? The robot was part of himself, his own neurosis moving to destroy him. And how can a man trick the trickiest part of himself? The right hand always finds out what the left hand is doing, the cleverest of devices never fools the supreme fooler for long.
He had gone about the thing in the wrong way, Perceveral thought, as he began to climb the mountain slope. The way to freedom is not through deception. It is…
The robot clutched at his heel, reminding Perceveral of the difference between theoretical and practical knowledge. Re pulled himself out of the way and bombarded the robot with stones. The robot brushed them aside and continued climbing.
Perceveral cut diagonally across the steep rock face. The way to freedom, he told himself, is not through deception. That was bound to fail. The way out is through change ! The way out is through conquest, not of the robot, but of what the robot represented.
Himself!
He was feeling lightheaded and his thoughts poured on unchecked. If, he insisted to himself, he could conquer his sense of kinship with the robot—then obviously the robot would no longer be his neurosis! It would simply be a neurosis, with no power over him.
All he had to do was lose his neurosis—even for ten minutes—and the robot couldn’t harm him!
All sense of fatigue left him and he was flooded with a supreme and intoxicating confidence. Boldly, he ran across a mass of jumbled rocks, a perfect place for a twisted ankle or a broken leg. A year ago, even a month ago, he would infallibly have had an accident. But the changed Perceveral, striding like a demigod, traversed the rocks without error.
The robot, one-armed and one-eyed, doggedly took the accident upon himself. He tripped and sprawled at full length across the sharp rocks. When he picked himself up and resumed the chase, he was limping.
Completely intoxicated but minutely watchful, Perceveral came to a granite wall, and leaped for a fingerhold that was no more than a gray shadow above him. For a heart-stopping second, he dangled in the air. Then, as his fingers began to slip, his foot found a hold. Without hesitation, he pulled himself up.
The robot followed, his dry joints creaking loudly. He bent a finger out of commission making the climb that Perceveral should have failed.
Perceveral leaped from boulder to boulder. The robot came after him, slipping and straining, drawing near. Perceveral didn’t care. The thought struck him that all his years of accident-proneness had gone into the making of this moment. The tide had turned now. He was at last what nature had intended him to be all along—an accident-proof man!
The robot crawled after him up a dazzling surface of white rock. Perceveral, drunk with supreme confidence, pushed boulders into motion and shouted to create an avalanche.
The rocks began to slide, and above him he heard a deep rumble. He dodged around a boulder, evaded the robot’s outflung arm and came to a dead end.
He was in a small, shallow cave. The robot loomed in front of him, blocking the entrance, his iron fist pulled back.
Perceveral burst into laughter at the sight of the poor. clumsy, accident-prone robot. Then the robot’s fist, driven by the full force of his body, shot out.
Perceveral ducked, but it wasn’t necessary. The clumsy robot missed him anyhow, by at least half an inch. It was just the sort of mistake Perceveral had expected of the ridiculous accident-prone creature.
The force of the swing carried the robot outward. He fought hard to regain his balance, poised on the lip of the cliff. Any normal man or robot would have regained it. But not the accident-prone robot. He fell on his face, smashing his last eye cell, and began to roll.
Perceveral leaned out to accelerate the roll, then quickly crouched back inside the shallow cave. The avalanche completed the job for him, rolling a diminishing black dot down the dusty white mountainside and burying it under tons of stone.
Perceveral watched it all, chuckling to himself. Then he began to ask himself what, exactly, he had been doing.
And that was when he started to shake.
Months later, Perceveral stood by the gangplank of the colony ship Cuchulain, watching the colonists step down into Theta’s midwinter sunshine. There were all types and kinds.
They had all come to Theta for a chance at a new life. Each of them was vitally important at least to himself, and each deserved a fighting chance at survival, no matter what his potentialities.
