Manning was still smiling at him.

"You can't reach me, Pete," he said. "You can only hurt yourself. You're enclosed within a solid wall of force that matter cannot penetrate."

A voice came from one corner of the room: "I'll bring Chizzy down next."

Pete whirled around and saw Russell Page for the first time. The scientist sat in front of a great control board, his swift, skillful fingers playing over the banks of keys, his eyes watching the instrument and the screen that slanted upward from the control banks.

Pete felt dizzy as he stared at the screen. He could see the interior of the ship he had been yanked from a moment before. He could see his three companions, talking excitedly, frightened by his disappearance.

His eyes flicked away from the screen, looked up through the skylight above him. Outlined against the sky hung the ship. At the nose and stern, two hemispheres of blue-white radiance fitted over the metal framework, like the jaws of a powerful vise, holding the craft immovable.

His gaze went back to the screen again, just in time to see Chizzy disappear. It was as if the man had been a mere figure chalked upon a board ... and then someone had taken a sponge and wiped him out.

Russ's fingers were flying over the keys. His thumb reached out and tripped a lever. There was a slight hum of power.

And Chizzy stood beside him.

Chizzy did not pull his gun. He whimpered and cowered within the invisible cradle of force.

"You're yellow," Pete snarled at him, but Chizzy only covered his eyes with his arms.

"Look, boss," said Pete, addressing Scorio, "what are you doing here? We left you back in New York."

Scorio did not answer. He merely glared. Pete lapsed into silence, watching.

Manning stood poised before the captives, rocking back and forth on his heels.

"A nice bag for one evening," he told Russ.

Russ grinned and stoked up his pipe.

Manning turned to the gangster chief. "What do you think we ought to do with these fellows? We can't leave them in those force sh.e.l.ls too long because they'll die for lack of air. And we can't let them loose because they might use their guns on us."

"Listen, Manning," Scorio rasped hoa.r.s.ely, "just name your price to let us loose. We'll do anything you want."

Manning drew his mouth down. "I can't think of a thing. We just don't seem to have any use for you."

"Then what in h.e.l.l," the gangster asked shakily, "are you going to do with us?"

"You know," said Manning, "I may be a bit old-fashioned along some lines. Maybe I am. I just don't like the idea of killing people for money. I don't like people stealing things other people have worked hard to get. I don't like thieves and murderers and thugs corrupting city governments, taking tribute on every man, woman and child in our big cities."

"But look here, Manning," pleaded Scorio, "we'd be good citizens if we just had a chance."

Manning's face hardened. "You sent these men here to kill us tonight, didn't you?"

"Well, not exactly. Stutsman kind of wanted you killed, but I told the boys just to get the stuff in the safe and never mind killing you. I said to them that you were pretty good eggs and I didn't like to b.u.mp you off, see?"

"I see," said Manning.

He turned his back on Scorio and started to walk away. The gangster chief came half-way out of his chair, and as he did so, Russ reached out a single finger and tapped a key. Scorio screamed and beat with his fists against the wall of force that had suddenly formed about him. That single tap on the great keyboard had sprung a trap, had been the one factor necessary to bring into being a force sh.e.l.l already spun and waiting for him.

Manning did not even turn around at Scorio's scream. He slowly paced his way down the line of standing gangsters. He stopped in front of Pete and looked at him.

"Pete," he said, "you've sprung a good many prisons, haven't you?"

"There ain't a jug in the System that can hold me," Pete boasted, "and that's a fact."

"I believe there's one that could," Greg told him. "One that no man has ever escaped from, or ever will."

"What's that?" demanded Pete.

"The Vulcan Fleet," said Greg.

Pete looked into the eyes of the man before him and read the purpose in those eyes. "Don't send me there! Send me any place but there!"

Greg turned to Russ and nodded. Russ's fingers played their tune of doom upon the keyboard. His thumb depressed a lever. With a roar five gigantic material energy engines screamed with thrumming power.

Pete disappeared.

The engines roared with thunderous throats, a roar that seemed to drown the laboratory in solid waves of sound. A curious refractive effect developed about the straining hulks as s.p.a.ce near them bent under their lashing power.

Months ago Russ and Greg had learned a better way of transmitting power than by metal bars or through conducting beams. Beams of such power as were developing now would have smashed atoms to protons and electrons.

Through a window in the side of the near engine, Greg could see the iron ingot used as fuel dwindling under the sucking force.

The droning died and only a hum remained.

"He's in a prison now he'll never get out of," said Greg calmly. "I wonder what they'll think when they find him, dressed in civilian clothes and carrying a heat gun. They'll clap him into a photo-cell and keep him there until they investigate. When they find out who he is, he won't get out--he has enough unfinished prison sentences to last a century or two."

For Pete was on one of the Vulcan Fleet ships, the h.e.l.l-ships of the prison fleet. There were confined only the most vicious and the most depraved of the Solar System's criminals. He would be forced to work under the flaming whip-lashes of a Sun that hurled such intense radiations that mere s.p.a.cesuits were no protection at all. The workers on the Vulcan Fleet ships wore suits that were in reality photo-cells which converted the deadly radiations into electric power. For electric power can be disposed of where heat cannot.

Quailing inside his force sh.e.l.l, Scorio saw his men go, one by one. Saw them lifted and whisked away, out through the depths of s.p.a.ce by the magic touch upon the keyboards. With terror-widened eyes he watched Russ set up the equations, saw him trip the activating lever, saw the men disappear, listened to the thunderous rumbling of the mighty engines.

Chizzy went to the Outpost, the harsh prison on Neptune's satellite. Reg went to t.i.tan, clear across the Solar System, where men in the infamous penal colony labored in the frigid wastes of that moon of Saturn. Max went to Vesta, the asteroid prison, which long had been the target of reformers, who claimed that on it 50 per cent of the prisoners died of boredom and fear.

Max was gone and only Scorio remained.

"Stutsman's the one who got us into this," wailed the gangster. "He's the man you want to get. Not me. Not the boys. Stutsman."

"I promise you," said Greg, "that we'll take care of Stutsman."

"And Chambers, too," chattered Scorio. "But you can't touch Chambers.

You wouldn't dare."
