That evening, just before he went to sleep, Moera opened the adjoining door and came into his room. Slim and warm, she slipped into his bed. When he started to speak, she put a hand over his mouth. And Barrent, who had learned not to question good fortune, kept quiet. The rest of the vacation passed much too quickly. The subject of the organization did not come up again; but, perhaps as compensation, the adjoining door was not closed. At last, late on the seventh day, Barrent and Moera returned to Tetrahyde. "When can I see you again?" Barrent asked. "I'll get in touch with you." "That's not a very satisfactory arrangement." "It's the best I can do," Moera said. "I'm sorry, Will. I'll see what I can do about the organization." Barrent had to be satisfied with that. When the vehicle dropped him at his store, he still didn't know where she lived, or what kind of an organization she represented. * * * * * Back in his apartment, he considered carefully the details of his dream in the Dream Shop. It was all there: his anger at Therkaler, the illicit weapon, the encounter, the corpse, and then the informer and the judge. Only one thing was missing. He had no recollection of the actual murder, no memory of aiming the weapon and activating it. The dream stopped when he met Therkaler, and started again after he was dead. Perhaps he had blocked the moment of actual murder out of his mind; but perhaps there had been some provocation, some satisfactory reason why he had killed the man. He would have to find out. There were only two ways of getting information about Earth. One lay through the horror-tinged visions of the Dream Shop, and he was determined not to go there again. The other way was through the services of a skrenning mutant. Barrent had the usual distaste for mutants. They were another race entirely, and their status of untouchability was no mere prejudice. It was well known that mutants often carried strange and incurable diseases. They were shunned, and they had reacted to exclusion by exclusiveness. They lived in the Mutant Quarter, which was almost a self-contained city within Tetrahyde. Citizens with good sense stayed away from the Quarter, especially after dark; everyone knew that mutants could be vindictive. But only mutants had the skrenning ability. In their misshapen bodies were unusual powers and talents, odd and abnormal abilities which the normal man shunned by day but secretly courted by night. Mutants were said to be in the particular favor of The Black One. Some people felt that the great art of Black Magic, about which the priests boasted, could only be performed by a mutant; but one never said so in the presence of a priest.
