"Well, what do you want to talk to me about?" he demanded. "Better make it brief. I'm not supposed to talk to you at all."

"I'm sorry to hear that," Corriston said. "You've got no idea how depressing it is to be locked up in a narrow cell with absolutely no one to talk to."

"You don't like it, eh? Well, you brought it on yourself."

Corriston caught the man about the waist and brought his right fist down three times on his curving back. Each blow was a powerful one, slanting downward toward the kidney.

Then Corriston hit the guard directly in the small of the back, with an even more punishing blow. The cumulative effect was instantaneous. The guard collapsed and sank down like a suddenly deflated balloon, the breath whistling from between his teeth.

Corriston watched him sink to the floor and straighten out. Forewarned as he was, he was still appalled by the almost instant, shocking change in the man's expression. For the second time the guard's features began to come apart. The entire upper portion of his face seemed to sink inward and broaden out, and the flowing began, the incredible refusal of his forehead and nose to remain in close proximity to his 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. The hooks were very tiny indeed, and their brightness was obscured by a thin film of sweat. Corriston removed the moisture with a quick flick of his thumb and continued to stare, as if he could not quite believe his eyes.
