The Human Edge
He crept up the tube at an angle into darkness. His eyes were useless, but the musky odor came strongly at him. Soon, he heard sounds.
There was an occasional ticking, then a thumping or shuffling sound. Finally, after he had crawled a long way up through the tube, there was a sound like a heavy puffing or hoarse breathing. It was the sound that had accompanied the strengthening of the musky odor once before; and this time the scent came strong again.
He lay, almost paralyzed with terror in the tube, as the odor grew in his nostrils. He could not move until sound and scent had retreated. As soon as they had, he wormed his way backward down to the lower level and freedom, replaced the grille, and fled for the outside air, once again.
But once more, in time he came back. Eventually he returned to explore the whole network of tubes to which the one he had entered connected. Many of the branching tubes were too small for him to enter, and the biggest tube he could find led to another grille from which the musky-smelling air was blasted with force.
Clearly it was the prime mover for the circulation of air through the exhaust half of the pyramid's ventilating system. Harry did not reason it out to himself in those intellectual terms, but he grasped the concept wordlessly and went back to exploring those smaller tubes that he could crawl into.
These, he found, terminated in grilles set in their floors through which he could look down and catch a glimpse of some chamber or other. What he saw was mainly incomprehensible. There were a number of corridors, a number of what could be rooms containing fixed or movable objects of various sizes and shapes. Some of them could be the equivalent of chairs or beds—but if so, they were scaled for a being plainly larger than himself. The lighting was invariably the low-key illumination he had encountered in the lower, machine level of the pyramid, supplied by the single luminescent strip running across the ceiling.
Occasionally, from one grille or another, he heard in the distance the heavy sound of breathing, among other sounds, and smelled more strongly the musky odor. But for more than a week of surreptitious visits to the pyramid, he watched through various grilles without seeing anything living.

However, a day finally came when he was crouched, staring down into a circular room containing what might be a bed shape, several chair shapes, and a number of other fixed shapes with variously spaced and depthed indentations in their surfaces. In a far edge of the circular room was a narrow alcove, the walls of which were filled with ranked indentations, among which several lights of different colors winked and glowed.
Suddenly, the dim illumination of the room began to brighten. The illumination increased rapidly, so that Harry cringed back from the grille, lifting a palm to protect his dimness-accustomed eyes. At the same moment, he heard approaching the sound of heavy breathing and sniffed a sudden increase in the musky odor.
He froze. Motionless above the grille, he stopped even his breathing. He would have stopped his heart if he could, but it raced, shaking his whole body and sounding its rapid beat in his ears until he felt the noise of it must be booming through the pyramid like a drum. But there was no sign from below that this was so.
Then, sliding into sight below him, came a massive figure on a small platform that seemed to drift without support into the room.
The aperture of the grille was small. Harry's viewpoint was cramped and limited, looking down directly from overhead. He found himself looking down onto thick, hairless brown-skinned shoulders, a thick neck with the skin creased at the back, and a forward sloping, hairless brown head, egg-shaped in outline from above, with the point forward.
Foreshortened below the head and shoulders was a bulging chinline with something like a tusk showing; it had a squat, heavy, hairless brown body and thick short forearms with stubby claws at the end of four-fingered hands. There was something walruslike about the tusks and the hunching; and the musky odor rose sickeningly into Harry's human nostrils.
The platform slid level with the alcove, which was too narrow for it to enter. Breathing hoarsely, the heavy figure on it heaved itself suddenly off the platform into the alcove, and the stubby hands moved over the pattern of indentations. Then, it turned and heaved itself out of the alcove, onto the flat, bed surface adjoining. Just as Harry's gaze began to get a full-length picture of it, the illumination below went out.
Harry was left, staring dazzled into darkness, while the heavy breathing and the sound of the figure readjusting itself on the bed surface came up to his ears. After a while, there was no noise but the breathing. But Harry did not dare move. For a long time he held his cramped posture, hardly breathing himself. Finally, cautiously, inch by inch, he retreated down the tube, which was too small to let him turn around. When he reached the larger tubes, he fled for the outside and the safety of the forest.
The next day, he did not go near the pyramid. Or the next. Every time he thought of the heavy brown figure entering the room below the grille, he became soaked with the clammy sweat of a deep, emotional terror. He could understand how the Other had not heard him or seen him up behind the grille. But he could not understand how the alien had not smelled him.
Slowly, however, he came to accept the fact that the Other had not. Possibly the Other did not have a sense of smell. Possibly . . . there was no end to the possibilities. The fact was that the Other had not smelled Harry—or heard him—or seen him. Harry was like a rat in the walls—unknown because he was unsuspected.
* * *
At the end of the week, Harry was once more prowling around back by the pyramid. He had not intended to come back, but his hatred drew him like the need of a drug addict for the drug of his addiction. He had to see the Other again, to feed his hate more surely. He had to look at the Other, while hating the alien, and feel the wild black current of his emotions running toward the brown and hairless shape. At night, buried in his nest of leaves, Harry tossed and snarled in his sleep, dreaming of the small stream backing up to flood the interior of the pyramid, and the Other drowning—of lightning striking the pyramid and fire racing through it—of the Other burning. His dreams became so full of rage and so terrible that he woke, twisting, and with the few rags of clothing that still managed to cling unnoticed to him soaked with sweat.
In the end, he went back into the pyramid.
Daily he went back. And gradually, it came to the point where he was no longer fearful of seeing the Other. Instead, he could barely endure the search and the waiting at the grilles until the Other came into sight. Meanwhile, outside the pyramid in the forest, the frill-edged leaves began to dry and wither and drop. The little stream sank in its bed—only a few inches, but enough so that Harry had to dig out the bottom of the streambed under the killing barrier in order to pass safely underwater into the pyramid area.
One day he noticed that there were hardly any of the treaded machines out taking samples in the woods any more.
He was on his way to the pyramid through the woods, when the realization struck him. He stopped dead, freezing in mid-stride like a hunting dog. Immediately, there flooded into his mind the memory of how the parking chamber for the treaded machines, inside the base of the pyramid, had been full of unmoving vehicles during his last few visits.
Immediately, also, he realized the significance of the drying leaves, the dropping of the water level of the stream. And something with the urgency of a great gong began to ring and ring inside him like the pealing of an alarm over a drowning city.
Time had been, when there had been no pyramid here. Time was now, with the year fading and the work of the collecting machines almost done. Time would be, when the pyramid might leave.
Taking with it the Other.
He began to run, instinctively, toward the pyramid. But, when he came within sight of it, he stopped. For a moment he was torn with indecision, an emotional maelstrom of fear and hatred all whirling together. Then, he went on.
* * *
He emerged a moment later, dripping, a fist-sized rock in each hand, to stand
before the closed door that gave the machines entrance to the pyramid. He stood staring at it, in broad daylight. He had never come here before in full daylight, but his head now was full of madness. Fury seethed in him, but there was no machine to open the door for him. It was then that the fury and madness in him might have driven him to pound wildly on the door with his stones or to wrench off one of the necks of the storklike machine at the stream and try to pry the door open. Any of these insane things he might have done and so have attracted discovery and the awesome power of the machinery and killing weapons at the command of the Other. Any such thing he might have done if he was simply a man out of his head with rage—but he was no longer a man.
He was what the Other had made him, an animal, although with a man locked inside him. And like an animal, he did not rave or rant, any more than does the cat at the mousehole, or the wolf waiting for the shepherd to turn in for the night. Instead, without further question, the human beast that had been Harry Brennan—that still called himself Harry Brennan, in a little, locked-away, back corner of its mind—dropped on his haunches beside the door and hunkered there, panting lightly in the sunlight, and waiting.
Four hours later, as the sun was dropping close to the treetops, a single machine came trundling out of the woods. Harry tricked it with one of his stones and, still carrying the other, ran into the pyramid.
He waited patiently for the small collecting machine to come and empty out the machine returned from outside, then dodged ahead of it, when it came, into the interior, lower level of the pyramid. He made his way calmly to the grille that gave him entrance to the ventilating system, took out the grille, and entered the tube. Once in the system, he crawled through the maze of ductwork, until he came at last to the grille overlooking the room with the alcove and the rows of indentations on the alcove walls.
When he looked down through the grille, it was completely dark below. He could hear the hoarse breathing and smell the musky odor of the Other, resting or perhaps asleep, on the bed surface. Harry lay there for a number of slow minutes, smelling and listening. Then he lifted the second rock and banged with it upon the grille.
* * *
For a second there was nothing but the echoing clang of the beaten metal in the darkness. Then the room suddenly blazed with light, and Harry, blinking his blinded eyes against the glare, finally made out the figure of the Other rising upright upon the bed surface. Great, round, yellow eyes in a puglike face with a thick upper lip wrinkled over two tusks stared up through the grille at Harry.
The lip lifted, and a bubbling roar burst from the heavy fat-looking shape of the Other. He heaved his round body off the bed surface and rolled, waddling across the floor to just below the grille.
Reaching up with one blunt-clawed hand, he touched the grille, and it fell to the floor at his feet. Left unguarded in the darkness of the ductwork, Harry shrank back. But the Other straightened up to his full near six-and-a-half feet of height and reached up into the ductwork. His blunt-clawed hand fastened on Harry and jerked. Off balance, Harry came tumbling to the floor of the chamber.
A completely human man probably would have stiffened up and broken both arms, if not his neck, in such a fall. Harry, animallike, attempted to cling to the shape of the Other as he fell, and so broke the impact of his landing. On the floor, he let go of the Other and huddled away from the heavy shape, whimpering.
The Other looked down, and his round, yellow eyes focused on the stone Harry had clung to even through his fall. The Other reached down and grasped it, and Harry gave it up like a child releasing something he has been told many times not to handle. The Other made another, lower-toned, bubbling roar deep in his chest, examining the rock. Then he laid it carefully aside on a low table surface and turned back to stare down at Harry.
Harry cringed away from the alien stare and huddled into himself, as the blunt fingers reached down to feel some of the rags of a shirt that still clung about his shoulders.
The Other rumbled interrogatively at Harry. Harry hid his head. When he looked up again, the Other had moved over to a wall at the right of the alcove and was feeling about in some indentations there. He bubbled at the wall, and a second later Harry's voice sounded eerily in the room.
"You . . . You are . . . the one I . . . made a beast . . ."
Harry whimpered, hiding his head again.
"You can't . . ." said Harry's voice, " . . . even speak now. Is . . . that so . . ."
Harry ventured to peek upward out of his folded arms, but ducked his head again at the sight of the cold, yellow eyes staring down at him.
" . . . I thought . . . you would be . . . dead by now," said the disembodied voice of Harry, hanging in the air of the chamber. " . . . Amazing . . . survival completely without . . . equipment. Must keep you now . . ." The eyes, yellow as topaz, considered Harry, huddled abjectly on the floor. " . . . cage . . . collector's item . . ."
The alien revolved back to the indentation of the wall a little way from the alcove. The broad, fleshy back turned contemptuously on Harry, who stared up at it.
The pitiful expression of fear on Harry's face faded suddenly into a soundless snarl. Silently, he uncoiled, snatched up the rock the Other had so easily taken from him, and sprang with it onto the broad back.
As he caught and clung there, one arm wrapped around a thick neck, the stone striking down on the hairless skull, his silent snarl burst out at last into the sound of a scream of triumph.
The Other screamed too—a bubbling roar—as he clumsily turned, trying to reach around himself with his thick short arms and pluck Harry loose. His claws raked Harry's throat-encircling arm, and blood streamed from the arm; but it might have been so much stage makeup for the effect it had in loosening Harry's hold. Screaming, Harry continued to pound crushingly on the Other's skull. With a furious spasm, the alien tore Harry loose, and they both fell on the floor.
The Other was first up; and for a second he loomed like a giant over Harry, as Harry was scrambling to his own feet and retrieving the fallen rock. But instead of attacking, the Other flung away, lunging for the alcove and the control indentations there.
Harry reached the alcove entrance before him. The alien dodged away from the striking rock. Roaring and bubbling, he fled waddling from his human pursuer, trying to circle around the room and get back to the alcove. Half a head taller than Harry and twice Harry's weight, he was refusing personal battle and putting all his efforts into reaching the alcove with its rows of indented controls. Twice Harry headed him off; and then by sheer mass and desperation, the Other turned and burst past into the alcove, thick hands outstretched and grasping at its walls. Harry leaped in pursuit, landing and clinging to the broad, fleshy back.
The Other stumbled under the added weight, and fell, face down. Triumphantly yelling, Harry rode the heavy body to the floor, striking at the hairless head . . . and striking . . . and striking . . .
VI
Sometime later, Harry came wearily to his senses and dropped a rock he no longer had the strength to lift. He blinked around himself like a man waking from a dream, becoming aware of a brilliantly lit room full of strange shapes—and of a small alcove, the walls of which were covered with rows of indentations, in which something large and dead lay with its head smashed into ruin. A deep, clawing thirst rose to take Harry by the throat, and he staggered to his feet.
He looked longingly up at the dark opening of the ventilator over his head; but he was too exhausted to jump up, cling to its edge, and pull himself back into the ductwork, from which he could return to the stream outside the pyramid and to the flowing water there. He turned and stumbled from the chamber into unfamiliar rooms and corridors.
A brilliant light illuminated everything around him as he went. He sniffed and thought he scented, through the musky reek that filled the air about him, the clear odor of water. Gradually, the scent grew stronger and led him at last to a room where a bright stream leaped from a wall into a basin where it pooled brightly before dra
ining away. He drank deeply and rested.
Finally, satiated, he turned away from the basin and came face-to-face with a wall that was an all-reflecting surface; and he stopped dead, staring at himself, like Adam before the Fall.
It was only then, with the upwelling of his returning humanness, that he realized his condition. And words spoken aloud for the first time in months broke harshly and rustily from his lips like the sounds of a machine unused for years.
"My God!" he said croakingly. "I've got no clothes left!"
And he began to laugh. Cackling, cackling rasping more unnaturally even than his speech, his laughter lifted and echoed hideously through the silent, alien rooms. But it was laughter all the same—the one sound that distinguishes man from the animal.
* * *
He was six months after that learning to be a complete human being again and finding out how to control the pyramid. If it had not been for the highly sophisticated safety devices built into the alien machine, he would never have lived to complete that bit of self-education.
But finally he mastered the controls and got the pyramid into orbit, where he collected the rest of his official self and shifted back through the alternate universe to Earth.
He messaged ahead before he landed; and everybody who could be there was on hand to meet him as he landed the pyramid. Some of the hands that had slapped his back on leaving were raised to slap him again when at last he stepped forth among them.
But, not very surprisingly, when his gaunt figure in a spare coverall now too big for it, with shoulder-length hair and burning eyes, stepped into their midst, not one hand finished its gesture. No one in his right senses slaps an unchained wolf on the back; and no one, after one look, wished to risk slapping the man who seemed to have taken the place of Harry.
Of course, he was still the same man they had sent out—of course he was. But at the same time he was also the man who had returned from a world numbered 1242 and from a duel to the death there with a representative of a race a hundred times more advanced than his own. And in the process he had been pared down to something very basic in his human blood and bone, something dating back to before the first crude wheel or chipped flint knife.
