Space Station 1

Ingenious was scarcely the word for it. It was a miracle of technological science, almost beyond belief. But he could not doubt the reality of what he saw, for he held the evidence in his hand. No hallucination could possibly be that real.

The way the mask’s surface coloration could change when the wearer’s emotions changed was perhaps the most amazing miracle of all. He had seen the guard’s color come and go, had watched him redden with anger and then grow pale.

It could only mean that there was some mechanically symbiotic, emotion-sensitive electronic coating or skin surface, or series of tubes on the inner surface of the mask, which could simulate actual blood flow much like a network of tiny heat regulators. This network would be so responsive to the slightest change in body temperature that the mask would alter its color the instant the wearer experienced fright or grew uncontrollably angry. What made it seem logical and even likely was the fact that caloric changes do occur in just such a fashion in the human body with every shift from anger to grief or from pain to shock.

There was nothing simple about the inner surface of the mask. It was a maze of complicated gadgetry concentrated in less than eight inches of space, perhaps thirty or forty separate mechanisms in all, some as tiny as the head of a pin, and others about one inch in width.

When the wearer became unconscious, the mask seemingly lost its integrity. The gadgets either stopped functioning or ceased to function properly and the false face became a dissolving, hideous caricature; that bore little or no resemblance to the human countenance in repose, or even to the human countenance convulsed with sudden shock.

How incredibly blind he had been in failing to suspect the existence of a mask when the guard’s face had grown unnatural and ghastly in the cafeteria. He had taken it for granted that it was the man himself who had changed.

Fortunately he was spared now from making the same mistake twice, and he took full advantage of the fact. He knelt again and began the by no means easy task of removing the uniform. He had to lift him up and turn him over twice and each time the man groaned and stirred a little. He seemed on the verge of coming to, but Corriston shut his mind to the possibility until the last of

the man’s garments had been tossed in a pile on the floor.

He quickly took off his own uniform then, and carefully and methodically arrayed himself as a guard, taking care to leave the coat unbuttoned at the throat and even going so far as to draw on the heavy woolen socks and attach to his wrist the guard’s metal identification disk.

An audacious thought Occurred to him, but he dismissed it at once. He could not attach the mask to his own face. It would have required the administrations of an expert, or, at the very least, someone familiar with the thing who knew exactly how it was supposed to be hooked into place. He had no way of knowing and he recoiled instinctively from the thought of hooks, however tiny, marring the skin on his face.

No, he’d have to get along without the mask. No one on the lower levels knew him by sight, with the one ugly exception of a killer he’d never seen clearly enough to recognize in return. And in the guard’s uniform he might even succeed in deceiving the killer if he moved quickly enough to give the man only a brief glimpse of him as he crossed the wide-view promenade.

CORRISTON stared down at the still unconscious guard, lying stretched out unclothed on the floor of the cell, then he turned, patting the guard’s gun which now nestled in its transferred holster on his angular, bony hip.

Well, there were perhaps even worse ways of ending up, and it was certainly a destiny almost universally shared.

He walked out through the open door of the cell without a backward glance.

He had changed his plans completely now. The complicated structure of the mask between his hands had so completely reassured him as to his complete sanity, that he was no longer under a compulsion to return to the Selector Compartment for additional proof.

All of the pieces were coming together and melting into a pattern that remained obscure only because there was still so much about it that he did not understand. He knew there was a killer loose on the Station, the same one who had been loose on the ship that had taken him to the Station. He knew about a poisoned barb that had killed one man and had barely missed killing Corriston himself.

Dismiss the killer for the moment. There was Helen Ramsey, the wealthiest girl on Earth. Think about Ramsey himself and what his wealth had done to Mars. Think about the colonists on Mars, men who had endured unimaginable hardships and privation to stake out uranium claims which Ramsey did not want them to have. Think about the freighter that had gone out of control.
