wait their time, until he won't know when
to expect it--and then they'll drop an H-bomb on him, if they have to.
That's faster than any nerve impulse!"

He swung back to face Hawkes, reaching for the door of the car. "Get
out, Will--and get as far away as you can. I'm not going to drive you
to your death. They'll get you eventually, but I won't be the one to
make it easier for them!"

Hawkes jerked. The old fear came back suddenly.

_You can't escape! They'll get you. Run! GO!_

He screamed, as the golden haze flickered again. He could wipe out the
Earth, but he couldn't survive, then. He could move back in time, but
it would only mean other dangers--no man could stay awake forever, and
he was used to civilized living.

The haze hesitated, while the sense of danger mounted. Then it was
gone, as if the beast in his head had found no answer.

Suddenly the gray sedan lifted again, to a height of fifty feet above
the tallest building. It shot forward, hesitated, and came down softly
on a deserted side-road in Central Park.

His mind felt as if it were going to split. Dan and Ellen stared at

needle in his arm, and he removed it!

He opened his eyes slowly, to find himself the center of a group of
men, while a white-clothed doctor stood staring at an empty hand that
must have held a hypodermic.

Ellen cried out suddenly, and ran to him, cradling his head in her
hands. He found her arm with his own hand, and stroked it slowly.

"You've found the answer?" he asked. Then he nodded, while the weight
that had lain on him so long began to lift. His voice was suddenly
positive. "You found it!"

One of the men pushed forward, but Dan shook his head, and came over
to stand beside the cot where Hawkes lay. "No, Will. They didn't find
it--you did! You found what we should have known--your unconscious
mind may be a wild beast, but it isn't insane. When it
