mouth. One eye closed completely; the other remained open in a wide and almost pupilless stare. The chin receded and the lips became a puckered gray orifice that looked like some monstrous fungus growth sprouting from the middle of a gargoyle face. The individual features became paler and paler as they spread, and suddenly there seemed to be no color left in the face at all. It had turned completely waxen. It was a horrifying thing to watch. Corriston knelt, opened the man's shirt and stared intently at the exposed throat, something he had not done the first time in the cafeteria. The first time he had simply knelt and searched under the shirt with his hand for a heartbeat which had surprised him by its steadiness. He was quite sure now that the heart was beating firmly and steadily. Even the peculiar appearance of the throat did not alarm him. But it most certainly did interest him. Far down on the Security Guard's throat, just above his breastbone, were a row of small hooks partly embedded in his flesh.

Undoubtedly the skin had been anaesthetized, the hooks inserted skillfully by someone familiar with just what should be done to prevent scarring. He hoped that the guard would not carry tiny scars on his face for the rest of his natural life. He arose and examined the mask. He had a complete false face. The thing was
