hen experiment with that
second one, without endangering Gault. He'd be careful not to
make this one thin and tall, so as not to resemble the Professor
in outline. Perhaps with it, he could trick the Entity into
releasing the missing part of Gault's body....

He scraped in the bench drawer for the scissors, and started to
sheer through a large stiff piece of paper.

A moment later he looked up as Pillbot walked over.

"Gault has some reason for not wanting his silhouette touched,"
he said. "Can't quite make out his lip movements, but he seems
afraid some permanent mark may be left on him by his return. He
wants time to figure out--why, what are you doing?"

"I've made another cutout for experiment," explained Harper. "And
this one doesn't look like the Professor, isn't tall and thin.
See--?" He lifted the second cutout from the flat surface of the
bench, held it suspended before him.

"This one is short and fat--" Harper halted abruptly, the breath
whooshing from his lungs.

There was no use talking to thin air. Pillbot had been whisked
into nothingness. Where the portly figure of the eminent
psychiatrist had stood was now nothing, not even a half man.

Too late, Harper realized that when he had lifted the paper
figure from the surface of the bench, the Entity had imitated him
by "lifting" Pillbot into the fourth dimension. Belatedly, he
knew that the cutout which he held dangling, resembled Pillbot in
outline.

Harper dashed back and forth in little rushes, carrying the paper
figure. He dared not put it down, for fear of seeing some segment
of Pillbot flash back. He did not know what to do with it.

Finally he compromised by suspending it to a low hanging
chandelier, where it dangled swaying in the slight air currents.

Gault was watching his assistant's antics with a bleak expression
that changed to sardonic satisfaction as he realized Pillbot was
in a predicament like his--only more so. Abruptly he frowned,
staring ahead, and Harper guessed that Pillbot had located
Gault's torso in the other realm, was nudging him to indicate the
fact.

Suddenly Harper knew that he himself must enter this fourth
dimensional realm. That strange instinct told him the solution to
everything was there--somewhat as a woman's intuition impels her
to act in a certain way, without knowing why.

How to get there? Another paper cutout? He glanced toward the
Professor--the occupied tr
