struggled furiously to tear away the steel-sinewed hand that had
stopped off his breath. Death was staring him in the face, and he
could not cry out. His strength left suddenly as the fingers dug in
deeper, and Eddie shook him as he would a rat. In a surprisingly short
time he had slumped to the floor, and not until his squirmings ceased
did Eddie loose that awful grip.

"Another notch, you spiggoty!"

Eddie bent over the controls. Lina's pleadings mingled with the curses
of Cadorna. She was cajoling now--telling the brute she'd go with him
gladly if only he'd free her father; promising anything, everything,
in the desperate attempt to keep him from discovering that his last
henchman was out of the picture. But her words served only to spur
Eddie to swifter action. He twirled the knobs of the dual control. The
second robot was fading from view. He'd give Cadorna a dose of the
thing he really feared. He eased off a little on the other control,
releasing the pressure on poor Shelton's ribs as much as he dared.

The position indicator of the second robot moved slightly as Eddie
started the invisible monster toward the yelling gangster. He watched
the screen closely. It was quite a trick, at that, controlling these
things you couldn't see. All you had to go by were these sketchy
representations in the teleview; tiny flecks of light that outlined
the various movable members of the robot.

"Eddie!" Lina screamed suddenly. "Look out!"

But he had seen Cadorna wheel around as he watched his image on the
screen. At that moment a tentacle was writhing its way around his
thick neck. A bullet whistled past Eddie's ear and buried itself
harmlessly in the wall.

Then from the blasphemous mouth of the king of gangland there came a
shriek of awful fear. The tightening tentacle shut it off in a choking
gurgle. Cadorna was captured at last--by a monster he could not see, a
monster that struck terror to his craven soul.

It was the work of but a moment to free David Shelton from the grip of
the other robot. The tortured man tottered into Lina's arms for
support.

Eddie played with Cadorna now, releasing the grip from his throat and
pinioning his arms instead. With rapid fingers he manipulated the
controls until the screaming gangster was raised high in the air by
the unseen arms of the robot.

"Another notch, Al," he chortled.

Cadorna yelled anew as the clamps tightened, "For God's
