Back in those days, a thousand years ago, men had built a system of government that historians called the feudal system. By this system certain men were called lords or barons and other t.i.tles. They held the power of life and death over the men "under" them.

This was what Spencer Chambers was trying to do with the Solar System ... what he would do if someone did not stop him.

Russ bit viciously on his pipe-stem.

The Earth, the Solar System, never could revert to that ancient way of government. The proud people sp.a.w.ned on the Earth, swarming outward to the other planets, must never have to bow their heads as minions to an overlord.

The thrum of power was beating in his brain, the droning, humming power from the engine rooms that would blast, once and forever, the last threat of dictatorship upon any world. The power that would free a people, that would help them on and up and outward to the great destiny that was theirs.

And this had come because, wondering, groping, curiously, he had sought to heat a slender thread of imperm wire within Force Field 348, because another man had listened and had made available his fortune to continue the experiments. Blind luck and human curiosity ... perhaps even the madness of a human dream ... and from those things had come this great ship, this mighty power, these many bulking pieces of equipment that would perform wonders never guessed at less than a year ago.

Greg Manning swiveled his chair. "Well, Russ, we're ready to begin.

Let's get Wrail first."

Russ nodded silently, his mind still half full of fleeting thought.

Absent-mindedly he knocked out his pipe and pocketed it, swung around to the manual of the televisor. His fingers reached out and tapped a pattern.

Callisto appeared within the screen, leaped upward at them. Then the surface of the frozen little world seemed to rotate swiftly and a dome appeared.

The televisor dived through the dome, sped through the city, straight for a penthouse apartment.

Ben Wrail sat slumped in a chair. A newspaper was crumpled at his feet.

In his lap lay a mangled dead cigar.

"Greg!" yelled Russ. "Greg, there's something wrong!"

Greg leaped forward, stared at the screen. Russ heard his smothered cry of rage.

In Wrail's forehead was a tiny, neatly drilled hole from which a single drop of blood oozed.

"Murdered!" exclaimed Russ.

"Yes, murdered," said Greg, and there was a sudden calmness in his voice.

Russ grasped the televisor control. Ranthoor's streets ran beneath them, curiously silent and deserted. Here and there lay bodies. A few shop windows were smashed. But the only living that stirred was a dog that slunk across the street and into the shadows of an alley.

Swiftly the televisor swung along the streets. Straight into the screen clanked a marching detail of government police, herding before them a half dozen prisoners. The men had their hands bound behind their backs, but they walked with heads held high.

"Revolution," gasped Russ.

"Not a revolution. A purge. Stutsman is clearing the city of all who might be dangerous to him. This will be happening on every other planet where Chambers holds control."

Perspiration ran down Russ's forehead and dripped into his eyes as he manipulated the controls.

"Stutsman is striking first," said Greg, calmly ... far too calmly.

"He's consolidating his position, possibly on the pretense that plots have been discovered."

A few buildings were bombed. A line of bodies were crumpled at the foot of a steel wall, marking the spot where men had been lined up and mowed down with one sweeping blast from a heater.

Russ turned the television controls. "Let's see about Venus and Mars."

The scenes in Ranthoor were duplicated in Sandebar on Mars, in New Chicago, the capital of Venus. Everywhere Stutsman had struck ...

everywhere the purge was wiping out in blood every person who might revolt against the Chambers-dictated governments. Throughout the Solar System violence was on the march, iron-shod boots trampling the rights of free men to tighten the grip of Interplanetary.

In the control room of the _Invincible_ the two men stared at one another.

"There's one man we need," said Greg. "One man, if he's still alive, and I think he is."

"Who is that?" asked Russ.

"John Moore Mallory," said Greg.

"Where is he?"

"I don't know. He was imprisoned in Ranthoor, but Stutsman transferred him some place else. Possibly to one of the prison fleet."

"If we had the records of the Callisto prison," suggested Russ, "we could find out."

"If we had the records ..."

"We'll get them!" Russ said.

He swung back to the keyboard again.

A moment later the administration offices of the prison were on the screen.

The two men searched the vision plate.

"The records are most likely in that vault," said Russ. "And the vault is locked."

"Don't worry about the lock," snapped Greg. "Just bring the whole d.a.m.n thing here--vault and records and all."

Russ nodded grimly. His thumb tripped the tele-transport control and from the engine rooms came a drone of power. In Ranthoor Prison, great bands of force wrapped themselves around the vault, clutching it, enfolding it within a sphere of power. Back in the _Invincible_ the engines screamed and the vault was ripped out of the solid steel wall as easily as a man might rip a b.u.t.ton from his shirt.

_CHAPTER FIFTEEN_

John Moore Mallory sat on the single metal chair within his cell and pressed his face against the tiny vision port. For hours he had sat there, staring out into the blackness of s.p.a.ce.

There was bitterness in John Moore Mallory's soul, a terrible and futile bitterness. So long as he had remained within the Ranthoor prison, there had always been a chance of escape. But now, aboard the penal ship, there was no hope. Nothing but the taunting reaches of s.p.a.ce, the mocking pinpoints of the stars, the hooting laughter of the engines.
