It was only then that he realized how weak and sick he was himself. Strange rays were tearing at his nerves and brain. His very flesh was slowly—very slowly—giving up its atomic power, in a gradual radioactive decay!
He stumbled at his first step and fell crashing to the floor. Paralysis rushed over him, and that droning sound was like a death-dirge in his ears. He tried to drag Ellen's unconscious form toward the door, but the effort was useless. He couldn't even crawl. He just lay there, panting torturedly, his hot brain working in a chaos of fever. He understood now.
The death of Mars all over again. The fused walls. The melted machines. The ozone in the air. A slow, creeping smouldering destruction had burnt itself out at last; perhaps when a new balance had been reached in the atoms of the Martian crust. A crust. A cancerous disease moving in an irregular path, depleting air and water. But there still must be a tiny part of the old process of atomic breakdown continuing on Mars today, maintaining, by electrical disturbances, the ozone in the air.
And he, Sam Conway, had started that same creeping horror here on Earth. It would go along now, spreading and spreading. The walls around him would soon be melting. And there was nothing a man could do to stop it. Not even the science of Mars had been able to save the world that had given it birth. Only in scattered places where the erratic horror had not reached, perhaps in deep crevices in the rocks, had a few plants and low animals been able to survive for a new beginning after most of the fires had died.
Sam Conway cursed himself for his eagerness and lust for power. He'd been like an old gold miner, he thought savagely, ready almost to kill his own brother to preserve his secret until he could use it for himself. There were too many men like that. And now Ellen and all the rest of the world had to suffer.
Mu. Atlantis. The asteroids that had perhaps once been a plant, destroyed, maybe, by a much more violent form of atomic breakdown. But who knew just what accidents might have caused these respective catastrophes? Science must sometimes get ahead of itself, without even outside influence. There was always a risk.
Sam's mind began to fade out, toward the nothingness of oblivion.
Then the real miracle began to happen. The violence of it jarred his brain swiftly back toward a semblance of awareness. Suddenly everything around him was spouting blue electric flame. The table, the chairs, the walls, even the grass and trees beyond the open doorway rippled with a sort of aura. The phenomenon lasted for only two seconds. It snapped and growled like the first dash of some gigantic code signal. Then it broke off. Then it began again.
Once more it stopped. And started.
