m; and even now his mind was filled with the horrible, paralyzing
fear he had felt that first night when he had made the discovery. Yet he
knew now that he dared not go back where he had come from.

At least he could understand why the not-men might have feared and
persecuted him, but he could not understand the horrible assault that
Dr. Webber had unleashed. And somehow he found Dr. Webber's attack
infinitely more frightening.

He seemed to be safe here, though, at least for the moment.

Quickly he moved down onto the nearest moving sidewalk heading toward
the living section of the New City. He knew where he could go there,
where he could lock himself in, a place where he could think, possibly
find a way to fight off Dr. Webber's attack of nightmares.

He settled back on a bench on the moving sidewalk, watching the city
slide past him for several minutes before he noticed the curious

mouth, choking back a scream as the hole moved with incredible rapidity
down the center of the strip, swallowing up whole rows of the seats,
moving straight toward his own.

He glanced in fright over the side just as the sidewalk moved out onto
the "bridge," and he gasped as he saw the towering canyons of buildings
fall far below, saw the seats tumble end over end, heard the sounds of
screaming blend into the roar of air by his ears.

Then the rift screamed by him with a demoniac whine and he sank back
onto his bench, ga
