"There's one difference," Matsukuo said analytically. "And that is that, although he has cut himself off from us and from the rest of the universe, he is still conscious in some little, walled-in compartment of his mind. He has no one there but himself—and that, I think, is damned poor company."
They waited then. When Pederson awoke, they were ready for him. His hatred took a slightly different form from Sager's, but the effect was the same.
And so were the results when the five bore down on him.
Again they waited. Lasser was next.
At first, it looked as though Lasser would go the way of Sager and Pederson, ending up as a hopelessly insane catatonic. Like his cohorts before him, Lasser retreated under the full pressure of the thought-probes of the five, building stronger and stronger walls.
But, quite suddenly, all his defenses crumbled. The mental barriers went down, shattered and dissolving. Lasser's whole mind lay bare. Instead of fighting and hating, Lasser was begging, pleading for help.
Lasser was not basically insane. His mind was twisted and warped, but beneath the outer shell was a personality that had enough internal strength to be able to admit that it was wrong and ask for help instead of retreating into oblivion.
"This one—I think we can do something with," Matsukuo's thought whispered.
Eight bodies, uncomfortable and pain-wracked, floated in space, chained to tiny asteroids that drifted slowly in their orbits under the constant pull of the sun. Two of them contained minds that were locked irrevocably within prisons of their own building, sealed off forever from external stimuli, but their suffering was the greater for all that.
The other six, chained though their limbs might be, had minds that were free—free, even, of any but the most necessary of internal limitations.
Eight bodies, chained to eight lumps of pitted rock, spun endlessly in endless space.
And then the ship came.
The flare of its atomic rocket could be seen for over an hour before it reached the Penal Cluster. The six eyed it speculatively. Although only two of them were facing the proper direction to see it with their physical eyes, the impressions of those two were easily transmitted to the other four.
"Another load of captives," whispered Juan Pedro de Cadiz. "How many this time, I wonder?"
"How long have we been here?" asked Houston, not expecting any answer.
"Who knows?" It was Lasser. "What we need out here is a clock to tell us when we'll die."
"Our oxygen tanks are our clocks," said Sonali. "And they'll notify us when the time comes."
"I do believe you morbid-minded people are developing a sense of humor," said Matsukuo, "but I'm not sure I care for the style too much."
The flare of the rocket grew brighter as the decelerating ship approached the small cluster of rocks. At last the ship itself took form, shining in the eternal blaze of the sun. When the whiteness of the rocket blaze died suddenly, the ship was only a few dozen yards from Houston's own asteroid.
And then a mental voice came into the minds of the six prisoners.
"How do you feel, Controllers?"
Only Houston recognized that thought-pattern, but his recognition was transmitted instantly to the others.
"Reinhardt!"
Hermann Reinhardt, Division Chief of the Psychodeviant Police, the one man most hated and feared by Controllers, was himself a telepath!
"Naturally," said Reinhardt. "Someone had to take control of the situation. I was the only one who was in a position to do it."
His thoughts were neither hard nor cold; it was almost as if he were one of them—except for one thing. Only the words of his thoughts came through; there were none of the fringe thoughts that the six were used to in each other.
"That's true," thought Reinhardt. "You see, we have been at this a good deal longer than you." Then he directed his thoughts at members of the crew of the spaceship, but they could still be heard by the six prisoners. "All right, men, get those people off those rocks. We have to make room for another batch."
The airlock in the side of the ship opened, and a dozen spacesuited men leaped out. The propulsion units in their hands guided them toward the prison asteroids.
"Give them all anaesthetic except Sager and Pederson," Reinhardt ordered. "They won't need it." Then, with a note of apology, "I'm sorry we'll have to anaesthetize you, but you've been in one position so long that moving you will be rather painful. We have to get you to a hospital quickly."
The minds of the six prisoners were frantically pounding questions at the PD chief, but he gave them no answer. "No; wait until you're better."
The spacesuited rescuers went to the "back" of each asteroid and injected sleep-gas into the oxygen line that ran from the tank to the spacesuit of the prisoner.
Houston could smell the sweetish, pungent odor in his helmet. Just before he blacked out, he hurled one last accusing thought at Reinhardt.
"You're the one who's been framing Controllers!"
"Naturally, Houston," came the answer. "How else could I get you out here?"
Houston woke up in a hospital bed. He was weak and hungry, but he felt no pain. As he came up from unconsciousness, he felt a fully awake mind guiding him out of the darkness.
It was Reinhardt.
"You're a tough man, Houston," he said mentally. "The others won't wake up for a while yet."
He was sitting on a chair next to the bed, holding a smouldering cigarette in one hand. He looked strange, somehow, and it took Houston a moment to realize that there was a smile on that broad, normally expressionless face.
Houston focussed his eyes on the man's face. "I want an explanation, Reinhardt," he said aloud. "And it better be a damned good one."
"I give you free access to my mind," Reinhardt said. "See for yourself if my method wasn't the best one."
Houston probed. The explanation, if not the best, was better than any Houston could have thought of.
When the hatred of the normal-minded people of Earth had been turned against the Controllers because of the actions of a few megalomaniacs, it had become obvious that legal steps had to be taken to prevent mob violence.
It had been Reinhardt himself who had suggested the Penal method to the UN government. At first, he had simply thought of it as a method to keep the Controllers alive until he could think of something better. But when he had discovered, by accident, what a small group of Controllers, alone in space, could do, he had set up the present machinery.
As soon as a Controller was spotted, a careful frame-up was arranged. Then, when several had been found, they were arrested in quick succession and sent to the asteroids.
Always and invariably, they had done what Houston's group had done—the sane or potentially sane ones had improved themselves tremendously, while the megalomaniacs had lapsed into catatonia.
"Why couldn't it be done on Earth?" Houston asked.
"We tried it," Reinhardt said. "It didn't work. Safe, on Earth, surrounded by Normals, a Controller still feels the hatred around him. He can't open his mind completely. Only the certain knowledge of impending death, and a complete freedom from the hatred of Normals can free the mind.
"And that's why you couldn't be told beforehand; if you knew you were going to be rescued, you wouldn't open up."
Houston nodded.
