Lee gnashed his teeth as he read the number of new casualties, women and children, too, who had become the victims of The Brain.

Arrived at "Grand Central" he kept a sharp lookout for any unusual activity. There was none. All along elevator-row small groups of bookish-looking men returned from their day's work in the Apperception Centers. They looked calm and contented and with their briefcases under their arms almost like ordinary businessmen heading for the commuter train.

He didn't dare to linger or to look around. There was this all-pervading sense of being shadowed, of having gone into a trap from which there was no escape, of eyes following him everywhere. Whose eyes? That was impossible to know. Maybe The Brain's; its sensory organs could conceivably be installed anywhere. Maybe that janitor guiding a polishing machine over the rubber floor was a plain clothesman; or maybe it was that detached gentleman who seemed to wait for an elevator with a stack of books under his arms.

As the cage shot up to Apperception 27, failure pressed down on his heart. Now it was almost thirty hours since he had released "Ant-termes" into the nerve paths of The Brain. Those undermining and devouring armies; what could have happened to them? Any number of things: Perhaps the Lignin in the nerve paths was poisonous. There had been no time for him to test the stuff. Perhaps the maintenance engineers had replenished the insulation in that sector overnight and all the hives were drowned. Perhaps some kind of a detecting apparatus had found out about the pest inside The Brain right from the start. As long as the beachhead of the underground invasion remained small, its blocking would not impair the functions of The Brain. What a fool he had been to pit dumb little animals against the powers of a God. Oona had been right; he was that knight in rusty armor charging against windmills on a Rozinante....


Vivian Leahy dragged him into the reception room of the medical center almost by force. "The doctors have been waiting for you two hours now," she scolded him. "They never did that before for any man. How come you forgot? And you forgot me too; last time you were so nice, I thought you would date me up. I couldn't have resisted your invitation, you know. Now, off with your coat."

Despite their irritation Mellish and Bondy received Lee with all their tweedy cordiality. While they piled their weird equipment around the operation table their tongues kept wagging: "The disappearance of the President; what did Lee make of that? Was he dead or alive? Those horrible catastrophes all over the country; what was behind all this? Foreign agents, a native underground? Didn't Lee think there was a tidal wave of anti-technology feeling arising since unemployment had again set in? And would the international crisis lead to war? The Brain, of course, would be the safest place in that event; but then, to think of the civilian population, an anticipated forty, fifty million dead; terrible wasn't it? Was Lee still able to concentrate upon his scientific work these harrowing days? If so, the nervous strain was terrific; they had experienced that in themselves. One reached the point of diminishing returns, didn't one? Yes, they had noticed signs of fatigue in Lee; discolorations under the eyes, a certain tenseness. Had he lost weight recently? He looked it and he certainly had none to spare. Did he suffer from insomnia? What you need is a good long rest, Dr. Lee."

He gave his answers automatically, detached, absent-minded almost. They were playing with him as a cat with a mouse. All their questions were leading questions; he knew that, but it didn't seem to matter now. Nothing mattered now after the great plan had failed, after his beautiful dream too had vanished in the talk with Oona last night. "I've outlived my usefulness," he thought.

The huge disk with the feeler-ray antennae sank down close to his chest, heavy as the keystone upon a tomb. The lights went out and then there was again that uncanny sensation of having millions of soldiers running circles all over one's skin, The Brain's vibration rays. They had a strange hypnotic effect. Deep instincts of life-preservation urged Lee to jump up, to rush those medics, to make some desperate attempt to get away. But as the rays now penetrated through the skin, they tied his muscles, although consciousness remained. There was a ghoulish quality in this, like being sucked into this apparatus, like having the very essence of one's life drained out by it. The only lights Lee saw, the glow of electronic tubes filtering through perforations in the walls of the machines, they seemed like evil eyes staring at him and the smooth lying voices from behind his head seemed as of mocking ghosts:

"Relax, Dr. Lee, relax. Let your mind wander at will. Think as the spirit moves you to think. Remember, this is a routine checkup, nothing but routine. Nothing to disturb you this time; we don't have to start you upon any specific trend of thought. You know The Brain by now and how it works; image-formation will start in a few moments. You have similar equipment in your own Apperception Center we understand. How does it work with that species you have discovered, 'Ant-termes Pacificus'? It's marvelous what these sensory rays can do; one would think that The Brain is really much more than a machine. The way it acts it seems alive, a towering intelligence, a superhuman personality with a will of its own. Don't you think so, Dr. Lee?"
