place ruled entirely by prisoners. It is a world where you could begin again, with no prejudices against you, with a clean record! Your past lives are forgotten. Don't try to remember them. Such memories would serve only to restimulate your criminal tendencies. Consider yourselves born afresh as of the moment of awakening in your cells." The speaker's slow, measured words had a certain hypnotic quality. 402 listened, his eyes slightly unfocused and fixed upon the speaker's pale forehead. "A new world," the speaker was saying. "You are reborn—but with the necessary consciousness of sin. Without it, you would be unable to combat the evil inherent in your personalities. Remember that.

The prisoners, still silent and dazed, were formed into a long line and marched out of the auditorium. Flanked by guards, they went down a corridor which stretched on interminably. From it, 402 began to get some idea of the size of the ship. Far ahead, he could see a
