He lay still.

Vanning didn’t look at the motionless body. He turned and began to follow Callahan’s trail. But he wasn’t watching the footprints. Some instinct seemed to guide him.
North ... North!
His head no longer hurt. It felt strangely cool, numb and stinging almost pleasantly. The magnetic pull drew him on. Deeper and deeper into the jungle....
Distantly he heard Goodenow’s shout, but ignored it. The consul couldn’t stop him. But he might try. Vanning ran for a while, lightly and easily, till the wilderness of Venus had swallowed him without trace. Then he slowed down to a walk. He would have been grateful for a brief rest, but he could not stop. Not Now....
The fog closed in. Silver mist veiled the strange, ghostly forest. Then it was torn away as a gust of wind drove down from the upper air. Above, the clouds twisted in tortured writhings; but Vanning did not look up. Not once did he turn his head. He faced north ... he plodded north ... he slogged through mushy, stinking swamp that rose at times to his waist....
A sane man would have skirted the bog. Vanning floundered across, and swam when he could no longer walk. Somewhere to the left he heard the coughing mutter of a swamp-cat’s engine, but he did not see the machine. His vision was restricted to a narrow circle directly ahead.
Dimly he felt pain. The clinging, soft nettles of Venus ripped at his clothing and his skin. Leeches clung to his legs till they fell off, satiated. Vanning went on. He was a robot—an automaton.
In silence the pale forest slipped by in a fantastic procession. Lianas often made a tangled snare where Vanning fought for minutes before breaking through. Luckily, the vines had little tensile strength, but soon the man was exhausted and aching in every limb. Far above, the clouds had thickened and darkened into what passed for night on fog-shrouded Venus. But the trees gave a phosphorescent light of their own. Weird beyond imagination was the scene, with the bloody, reeling figure of the man staggering on toward the north—
North. Ever north. Until overtaxed muscles refused to bear the burden longer, and Vanning collapsed into exhausted unconsciousness.
He did not know when he awoke. Presently he found himself walking again. Nothing had changed. The jungle was denser, and the cool light from above filtered down once more. Only the light was cool. The air itself was sticky and suffocating.
He went on into hell.
Days and nights merged into a fantastic pattern of dull torture. Some distantly sane portion of his brain held back and watched, but could not help. Days and nights. There was no food. There was water, for as Vanning splashed through shallow pools he would bend his head to drink of the foul liquid. Once his feet crunched on the green-moulded bones of a human skeleton. Others had taken this way before him....

Toward the end, a fleshless, gaunt thing that had once been a man dragged itself laboriously toward a range of mountains that lifted from the swamp toward the north. They extended to left and right as far as he could see, and seemed unscalable. But they were V-shaped, and Vanning headed toward the point of the V—the inner point. The terrible drive within him drove him on relentlessly.
That night a sulphurous crimson glow lit the sky beyond the mountains. Vanning did not see it. He slept.
By morning he was on his way again, staggering into the funnel of the peaks. They were bare rock, eroded by eons of trickling water from the clouds. He could not climb them, even had he possessed the strength. He went on, instead, into the narrowing valley....
It ended in a sheer cliff of weathered stone. Vanning reeled toward the barrier. He could not return. The North-Fever drove him on remorselessly. He had to climb that wall of rock, or die. And he could not climb.
He fell, rose, and fell again. In the end he crawled. He crawled to the foot of the cliff and dragged himself upright. He fell forward, as though trying to press his body against the towering wall that lifted to the writhing grey clouds—
Fell—through the stone!
He toppled through the rock curtain as though it were non-existent! Instantly intense blackness closed around him. Hard stone was under him.
His mind was too dulled to wonder. He knew only that the way north was still open. He crept on through darkness, leaving a trail of blood behind him....
The ground dropped from under him. He crashed down on a mound of moulded vegetation.
Before the shock had passed, the living dead man was moving again. He crawled forward until his way was blocked by a perpendicular wall. Gasping dry-throated sobs, he clawed at the barrier with broken, bleeding finger-tips.
To left and right, an arm’s length away, were other walls. He was in a pit. The sane part of his brain thought: "Circle around! There may be some way out!"
But Vanning could not circle. He could only move in one direction. That was north. He fumbled blindly at the wall, until unconsciousness came at last....
Twice again he awoke, each time weaker, and twice again he slept. The fever, having passed its peak, dwindled swiftly.
At last Vanning awoke, and he was sane. No longer did he feel the relentless urge to turn north. He lay for a little while staring into the blackness, realizing that he was once more in full command of his traitorous body.
There was little life left in him. His tongue was blackened and swollen till it filled his mouth. He was a scarecrow, nearly naked, his bones sharply defined through his skin.
It was an effort even to breathe. But death would not be long in coming—now....
II
Dying is an uncomfortable business, unless a man is drugged or insensible. Vanning found it so. Moreover, he wasn’t the sort of man who would give up without good cause. Weak as he was, nevertheless he was still too strong to lie in the dark, waiting.
Laboriously, he got to his hands and knees and commenced a circuit of the pit. He expected nothing. But, at the southern end of his prison, he was astounded to find a hole in the wall easily large enough to admit his body.
Feeling into the blackness, he discovered the smooth floor of a passage. Good Lord! It had been there all the time, during his tortured imprisonment in the pit. If he had only searched before—
But he could not have done so, of course. Not with the North-Fever flaming in his veins.
The tunnel might lead anywhere. All the chances were against its leading to safety. Sooner or later, there would probably be a dead end. Nevertheless, there was a chance. That chance grew brighter as Vanning’s fingers discovered that the walls bore the marks of tools.
The tunnel had been made by—perhaps not humans, but at least by some intelligent race!
It grew higher as he went on, but Vanning was too weak to rise. He realized dimly that the passage made a sharp hairpin turn.
Through the dark the distant clangor of a bell roared.
Vanning hesitated, and then resumed his weak crawl. There was nothing else to do.
The ground dropped from beneath him. He went rolling and slipping down an inclined slide, to stop with a jolt against a softly padded surface. The shock was too much for his exhausted mind and body. He felt consciousness leaving him.
But he realized that it was no longer dark. Through a pale, luminous twilight he caught a glimpse of a mask hovering over him—the mask of no human thing. Noseless save for tiny slits, gap-mouthed, round-eyed, the face was like that of a fish incredibly humanized—fantastically evolved. A patina of green scales overlaid the skin.
The gong thundered from nearby. The monstrous mask dissolved into the blackness that swept up and took Vanning to its heart. Nothing existed but pain, and that, too, was wiped out by the encompassing dark....
