With the coming of the Controllers, a movement had arisen to bring back the old evil of judicial murder, but it had been quickly put down when the Penal Cluster plan had been put forth as a more "humane" method.

Hibernene was a drug that had been evolved from the study of animals like the bear, which spent its winters in an almost death-like sleep. A human being, given a proper dosage of the drug, lapsed into a deep coma. The bodily processes were slowed down; the heart throbbed sluggishly, once every few minutes; thought ceased. It was the ideal prison for a mental offender that ordinary prisons could not hold.

But it wasn't quite enough for the bloodthirsty desire for vengeance that the Normals held for the Controllers. There had to be more.

Following Earth in its orbit around the sun, trailing it by some ninety-three million miles, were a group of tiny asteroids, occupying what is known as the Trojan position. They were invisible from Earth, being made of dark rock and none of them being more than fifteen feet in diameter. But they had been a source of trouble in some of the early expeditions to Mars, and had been carefully charted by the Space Commission.

Now a use had been found for them. A man in a spacesuit could easily be chained to one of them. With him was a small, sun-powered engine and tanks of liquified food concentrates and oxygen. Kept under the influence of hibernene, and kept cool by the chill of space, a man could spend the rest of his life there—unmoving, unknowing, uncaring, dead as far as he and the rest of Mankind were concerned—his slight bodily needs tended automatically by machine.

It was a punishment that satisfied both sides of the life-or-death argument.

Houston shook off the bleak, black feeling of terrible chill that had crept over him and pushed his way into the UN Police building.


The thirteenth floor housed the Psychodeviant Division. As he stood in the rising elevator, Houston wondered wryly if the number 13 was good luck or bad in this case.

He stepped out of the elevator and headed for the Division Chief's office.
