plessly.

If only they would move, do something he could counter.

But he wasn't even sure any more that he could detect them. And they
were so careful never to move into the open.

He jumped up feverishly, moved to the window, and peered between the
slats of the dusty, old-fashioned blind at the street below.

An empty street at first, wet, gloomy. He saw no one. Then he caught the
flicker of light in an entry several doors down and across the street,
as a dark figure sparked a cigarette to life. Harry felt the chill run
down his back again. Still there, then, still waiting, a hidden figure,
always present, always waiting....

Harry's eyes scanned the rest of the street rapidly. Two three-wheelers
rumbled by, their rubber hissing on the wet pavement. One of them
carried the blue-and-white of the Old City police, but the car didn't
slow up or hesitate as it passed the dark figure in the doorway. They
would never help me anyway, Harry thought bitterly. He had tried that
before, and met with ridicule and threats. There would be no help from
the police in the Old City.

Another figure came around a corner. There was something vaguely
familiar about the tall body and broad shoulders as the man walked
across the wet street, something Harry faintly recognized from somewhere
during the spinning madness of the past few weeks.

The man's eyes turned up toward the window for the briefest instant,
then returned steadfastly to the street. Oh, they were sly! You could
never spot them looking at you, never for _sure_, but they were always
there, always nearby. And there was no one he could trust any longer, no
one to whom he could turn.

Not even George Webber.

Swiftly his mind reconsidered that possibility as he watched the figure
move down the street. True, Dr. Webber had started him out on this
search in the first place. But even Webber would never believe what he
had found. Webber was a scientist, a researcher.

What could he do--go to Webber and tell him that there were men alive in
the world who were _not_ men, who were somehow men and something more?

Could he walk into Dr. Webber's office in the Hoffman Medical Center,
walk through the gleaming bright corridors, past the shining metallic
doors, and tell Dr. Webber that he had found people alive in the world
who could actually see in four dimensions, live in four dimensions,
_think_ in four dimensions?

Could he explain to Dr. Webber that he knew this simply bec
