Muller knew the maze quite well by this time. He understood its snares and its delusions, its pitfalls, its deadly traps. He had lived within it for nine years. That was long enough to come to terms with the maze, if not with the situation that had driven him to take refuge within it.
He still moved warily. Three or four times already he had learned that his knowledge of the maze, although adequate and workable, was not wholly complete. At least once he had come right to the edge of destruction, pulling back only by some improbable bit of luck just before the unexpected fountaining of an energy flare sent a stream of raw power boiling across his path. Muller had charted that flare, and fifty others; but as he moved through the city-sized labyrinth he knew there was no guarantee that he would not meet an uncharted one.
Overhead the sky was darkening; the deep, rich green of late afternoon was giving way to the black of night. Muller paused a moment in his hunting to look up at the pattern of the stars. Even that was becoming familiar now. He had chosen his own constellations on this desolate world, searching the heavens for arrangements of brightness that suited his peculiarly harsh and bitter taste. Now they appeared: the Dagger, the Back, the Shaft, the Ape, the Toad. In the forehead of the Ape flickered the small grubby star that Muller believed was the sun of Earth. He was not sure, because he had destroyed his chart tank after landing here somehow, though, he felt that that minor fireball must be Sol. The same dim star formed the left eye of the Toad. There were times when Muller told himself that Sol would not be visible in the sky of this world ninety light-years from Earth, but at other times he was quite convinced. Beyond the Toad lay the constellation that Muller had named Libra, the Scales. Of course, this set of scales was badly out of balance.
Three small moons glittered here. The air was thin but breathable; Muller had long ago ceased to notice that it had too much nitrogen, not enough oxygen. It was a little short on carbon dioxide, too, and one effect of that was that he hardly ever seemed to yawn. That did not trouble him. Gripping the butt of his gun tightly, he walked slowly through the alien city in search of his dinner. This too was part of a fixed routine. He had six months' supply of food stored in a radiation locker half a kilometer away, but yet each night he went hunting so that he could replace at once whatever he drew from his cache. It was a way of devouring the time. And he needed that cache, undepleted, against the day when the maze might cripple or paralyze him. His keen eyes scanned the angled streets ahead. About him rose the walls, screens, traps and confusions of the maze within which he lived. He breathed deeply. He put each foot firmly down before lifting the other. He looked in all directions. The triple moonlight analyzed and dissected his shadow, splitting it into reduplicated images that danced and sprawled before him.
The mass detector mounted over his left ear emitted a high-pitched sound. That told Muller that it had picked up the thermals of an animal in the 50-100 kilogram range. He had the detector programmed to scan in three horizons, of which this was the middle one, the food-beast range. The detector would also report to him on the proximity of 10-20 kilogram creatures--the teeth-beast range--and on the emanations of beasts over 500 kilograms--the big-beast range. The small ones had a way of going quickly for the throat, and the great ones were careless tramplers; Muller hunted those in between and avoided the others.
Now he crouched, readying his weapon. The animals that wandered the maze here on Lemnos could be slain without stratagem; they kept watch on one another, but even after all the years of Muller's presence among them they had not learned that he was predatory. Not in several million years had an intelligent life-form done any hunting on this planet, evidently, and Muller had been potting them nightly without teaching them a thing about the nature of mankind. His only concern in hunting was to strike from a secure, well-surveyed point so that in his concentration on his prey he would not fall victim to some more dangerous creature. With the kickstaff mounted on the heel of his left boot he probed the wall behind him, making certain that it would not open and engulf him. It was solid. Good. Muller edged himself backward until his back touched the cool, polished stone. His left knee rested on the faintly yielding pavement. He sighted along the barrel of his gun. He was safe. He could wait. Perhaps three minutes went by. The mass detector continued to whine, indicating that the beast was remaining within a hundred-meter radius; the pitch rose slightly from moment to moment as the thermals grew stronger. Muller was in no hurry. He was at one side of a vast plaza bordered by glassy curving partitions, and anything that emerged from those gleaming crescents would be an easy shot. Muller was hunting tonight in Zone E of the maze, the fifth sector out from the heart, and one of the most dangerous. He rarely went past the relatively innocuous Zone D, but some daredevil mood had prodded him into E this evening. Since finding his way into the maze he had never risked G or H again at all, and had been as far out as F only twice. He came to E perhaps five times a year.
To his right the converging lines of a shadow appeared, jutting from one of the curving glassy walls. The song of the mass detector reached into the upper end of the pitch spectrum for an animal of this size. The smallest moon, Atropos, swinging giddily through the sky, changed the shadow pattern; the lines no longer converged, but now one bar of blackness cut across the other two. The shadow of a snout, Miller knew. An instant later he saw his victim. The animal was the size of a large dog, gray of muzzle and tawny of body, hump-shouldered, ugly, spectacularly carnivorous. For his first few years here Muller had avoided hunting the carnivores, thinking that their meat would not be tasty. He had gone instead after the local equivalent of cows and sheep--mild-mannered ungulates which drifted blithely through the maze cropping the grasses in the garden places. Only when that bland meat palled did he go after one of the fanged, clawed creatures that harvested the herbivores, and to his surprise their flesh was excellent. He watched the animal emerge into the plaza. Its long snout twitched. Muller could hear the sniffing sounds from where he crouched. But the scent of man meant nothing to this beast.
Confidently, swaggeringly, the carnivore strode across the sleek pavement of the plaza, its unretracted claws clicking and scraping. Muller fined his beam down to needle aperture and took thoughtful aim, sighting now on the hump, now on the hindquarters. The gun was proximity-responsive and would score a hit automatically, but Muller always keyed in the manual sighting. He and the gun had different goals--the gun was concerned with killing, Muller with eating; and it was easier to do his own aiming than to try to convince the weapon that a bolt through the tender, juicy hump would deprive him of the tastiest cut. The gun, seeking the simplest target, would lance through that hump to the spine and bring the beast down: Muller favored more finesse.
He chose a target six inches forward from the hump: the place where the spine entered the skull. One shot did it. The animal toppled heavily. Muller went toward it as rapidly as he dared, checking every footfall. Quickly he carved away the inessentials--limbs, head, belly--and sprayed a seal around the raw slab of flesh he cut from the hump. He sliced a hefty steak from the hindquarters, too, and strapped both parcels to his shoulders. Then he swung around, searching for the zigzagging road that was the only safe entry to the core of the maze. In less than an hour he could be at his lair in the heart of Zone A.
He was halfway across the plaza when he heard an unfamiliar sound.
Pausing, he looked back. Three small loping creatures were heading toward the carcass he had abandoned. But the scrabbling of the scavengers was not what he had heard. Was the maze preparing some new deviltry? It had been a low rumbling sound overlaid by a hoarse throb in the middle frequencies, too prolonged to be the roaring of one of the large animals. It was a sound Muller had not heard before.
No: a sound he had not heard here before. It registered somewhere in his memory banks. He searched. The sound was familiar. That double boom, slowly dopplering into the distance--what was it?
He placed its position. The sound had come from over his right shoulder, so it seemed. Muller looked there and saw only the triple cascade of the maze's secondary wall, rising in tier upon glittering amber tier. Above that wall? He saw the star-brightened sky: the Ape, the Toad, the Scales.
Muller remembered the sound now.
A ship; a starship, cutting out of warp onto ion drive to make a planetary landing. The boom of the expellers, the throb of the deceleration tubes, passing over the city. It was a sound he had not heard in nine years, since his self-exile on Lemnos had begun. So he was having visitors. Casual intruders, or had he been traced? What did they want? Anger blazed through him. He had had enough of them and their world. Why did they have to trouble him here? Muller stood braced, legs apart, a segment of his mind searching as always for perils even while he glared toward the probable landing point of the ship. He wanted nothing to do with Earth or Earthmen. He glowered at the faint point of light in the eye of the Toad, in the forehead of the Ape.
They would not reach him, he decided.
They would die in the maze, and their bones would join the million-year accumulation that lay strewn in the outer corridors.
And if they succeeded in entering, as he had done--
Well, then they would have to contend with him. They would not find that pleasant. Muller smiled grimly, adjusted the meat on his back, and returned his full concentration to the job of penetrating the maze. Soon he was within Zone C, and safe. He reached his lair. He stowed his meat. He prepared his dinner. Pain hammered at his skull. After nine years he was no longer alone on this world. They had soiled his solitude. Once again, Muller felt betrayed. He wanted nothing more from Earth than privacy, now; and even that they would not give him. But they would suffer if they managed to reach him within the maze. If.

As the first human to interact with an intelligent alien species, Richard Muller learned almost nothing during his year-long visit to the home planet of the strange, silent Hydrans. At the end of his mission, Muller discovers that the Hydrans secretly altered his mind to radiate his emotions to any human who comes near. He quickly learns from his friends and companions that experiencing the horrifying reality of a human soul invariably induces revulsion and despair. Rejected from society, Muller renounces his allegiance to the human race and isolates himself as the only being ... human or alien ... to successfully navigate the hidden death-traps into the center of the abandoned city of Lemnos. After nine years of contented solitude, a bitter and cynical Muller watches as a human crew arrives at the gate of the city and attempts to penetrate the maze. He is not aware that their mission to end his self-imposed isolation is more than the rescue of one man, it is a desperate attempt to rescue the fate of mankind.
