sake, kid,
quit it! Let me down. I'll do anything you say."

"Yeah?" Eddie moved one of the rheostat knobs a trifle.

The prince of racketeers was whimpering now, like a baby. The sharp
snap of a rib punctured his outcries.

"Another notch," said Eddie grimly.

But the king of the underworld had fainted.

An hour later Eddie Vail surveyed the scene complacently. Lina had
washed the blood from his head and face and bandaged his wound.
Luckily, Cardorna's blow had been a glancing one. The girl was fussing
over her father, now, and the scientist was on the point of resenting
her attentions; swore he could take care of himself; he wasn't a baby.
Carlos and his chief were trussed up like mummies, and had been
snarling at each other ever since the Chilean recovered his senses,
each blaming the other for their predicament. The robots stood
motionless by the wall.

This would be a big haul for the police. Plenty of evidence to send
Cadorna to the chair now. The murder of Butch Collins, the undersized
thug, had been witnessed by three of them. No, four: Carlos would
squeal. He was that kind. There would be rejoicing in the underworld
too, for Cadorna had many enemies. They'd be killing each other off in

his place.

"Guess we'll have to dump them in the limousine," he remarked to

authorities."

"Yes. Then they can come back for the bodies of the other two."
Shelton grimaced as he contemplated the sprawled figures.

"What about your robots?" Eddie asked.

"Why, I'll go ahead with my original plans, of course." The scientist
looked surprised.

"Dad!" Lina turned beseeching eyes on Eddie and his heart performed
amazingly as he looked into their depths.

"And why not?" asked her father dolefully. "They'll insure the peace
of the world. They'll--"

"Listen, Mr. Shelton," Eddie interrupted. "If you'll think a little
you'll realize that they'll do no such thing. Has any new and terrible
engine of destruction ever accomplished that result? No--the enemy
always finds a way of combating the new weapon and of devising another
still more terrible. You've discovered a marvelous thing, but its
value is quite problematical."

"How can they ever combat a thing they cannot see?"

"Easily. Why, I could devise a teleview attachment in two days that
