THE GIRL IN HIS MIND The dance that the chocoletto girl was performing was an expurgated it was still on the lascivious side. The G-string that constituted the chocoletto girl's entire costume put her but one degree above the nakedness which the original dance demanded. Nathan Blake's voice was next to match the furious bump and grind of her hips. For a chocoletto she was light-skinned—more bronze, really, than brown. But then, the word "chocoletto", coined by the early beche-la-mer traders, was She was beautiful too. Her high-cheekboned face was striking—the eyes vivid white line between the half-parted purple lips. And her body was night and made his way through the labyrinthine alleys of the native sector. In common with all chocoletto huts, Eldoria's was uncared for on the outside, and gave a false impression of poverty. He expected to find the usual hanger-on waiting in the anteroom, and looked forward to A human girl. . Her hair made him After closing the door, he sat down opposite her on the guest mat. Behind her, a gaudy arras hid the hut's other room. "You are here to wait for Eldoria?" she asked. Blake nodded. "And you?" She laughed. "I am here because I live here," she said. Dubhe 4. They died of yellow-water dysentery before their indenture ran out, and in accordance with Interstellar Law I was auctioned off along with the rest of their possessions. Eldoria bought me." Five years as a roving psycheye had hardened Blake to commercial colonization practices "Fourteen." "And what are you going to be when you grow up?" "Probably I shall be a psychiatrist. Eldoria is sending me to the mission school now, and afterward she is going to put me through an institute of higher learning. And when I come of age, she is going to them. When I grow up I shall be a most well-educated person." "I'm sure you will be," Blake said, looking at the arras. "My name is Deirdre." "Nathan," Blake said. "Nathan Blake." "Eldoria will be arriving soon. I must go and prepare her dais." She got up, parted the arras, and slipped into the next room. Shame flamed in Blake's cheeks, and for a moment he considered leaving then he remembered Eldoria's dance, and he went right on sitting where he was. again, and silence was pounding silent fists upon the walls. He was relieved when Eldoria finally arrived. She ushered him into the next room immediately. It was slightly larger than the anteroom, and much more richly appointed. A thick carpet the color of Martian and took up nearly half the floor space. It was strewn with scarlet cushions. Blake sat down upon it. Nervously he watched Eldoria slip out of her white street robe, his eyes moving back and forth from her smooth dark skin to the arras. The incense thickened around him. duplicated sand. Sabrina York did not even know the rudiments of the art of throwing off a mind-tracker. It would have done her but little good if she presence. Sabrina's footsteps led up to the front door, and the door itself was colored box of his mother's favorite detergent with a full-length drawing of Vera Velvetskin, the company's blond and chic visual symbol, eye, and thinking that he had read the two words wrong, he stepped closer so that he could see them more clearly. No, he had made no mistake: the first word was "Sabrina", and the second was "York". He stepped back. Odd that a kitchen range should have the same name as his quarry. But perhaps not unduly so. Giving appliances human names had been common practice for centuries. Even a name like "Sabrina York", while certainly not run-of-the-mill, was bound to be duplicated in real life. Nevertheless a feeling of uneasiness accompanied him when He went through each room systematically, but saw no sign of Sabrina York. He lingered for some time in his own room, wistfully watching his The leaving the house by way of the back door. He picked up Sabrina's trail to revisit, nor a moment that he cared to relive, but Sabrina's trail slightly deeper than its predecessors indicated that Sabrina had Deirdre was speaking. "Yes," she was saying, "at nine o'clock. And I from the way you talk that you are centuries old!" "I'm thirty-eight," Blake Past said, "and while I may not be your father, I'm certainly old enough to be. That young man—" A pink flush of anger climbed into Deirdre Eldoria's girlish cheeks. "What right has he "Please," Blake Past said, desperation deepening his voice. "You're only making everything worse. After majoring in Trevorism, you certainly ought to realize by now that there was nothing noble about my buying you after Eldoria died. I only did it to ease my conscience—" "What do you "I'll come to New Earth to visit you," Blake said. "Venus is only a few was shock. His third was fear. His amazement resulted from recognition. One of the three women arrayed before him was Miss Stoddart, his boyhood Sunday-school teacher. blond and chic Vera Velvetskin, whose picture he had seen on box after countless box of his mother's favorite detergent. His shock resulted from the expressions on the three faces. Neither much that their hatred had thinned out their faces and darkened their eyes. More shocking yet, Vera Velvetskin, who had never existed save greater thinness of her face and the more pronounced darkness of her eyes, she hated him even more than Miss Stoddart and Officer Finch did. His fear resulted from the realization that his mind-world contained Stoddart said. "Callous creature who did a maiden's innocence affront!" said Officer Finch. "And sought sanctuary in ill-fitting robes of righteousness!" said Vera Velvetskin. The three faces moved together, blurred and seemed to blend into one. The three voices were raised in unison: "You know who we are, Nathan Blake. You know who we are!" own right and that he too was capable of creating universes. Trivial universes, to be sure, when compared with the grandeur and scope of the objective one, and peopled with ghosts instead of human beings The discovery came about quite by accident.

Unaccountably she had was hiding out in his mind. Retiring to his bachelor quarters, he had entered at the same place-time and set off in pursuit. Her only advantage lost, Sabrina York was now at his mercy. Unless she discovered his presence and was able to locate his most recently materialized place-time before he over-took her, her capture was assured. whom he had told about it were aware that it had ever existed. How, then, had a total stranger such as Sabrina York learned enough about it to enable her to use it as a point of entry? beings considerably higher on the scale of mind-country evolution own mind had created a walking-talking Virgin Mary who watched over and moreover, the super-image in each instance had been an image that to create. Therefore, even assuming that Blake was less well-adjusted than he considered himself to be, why had he created three such malevolent super-images as Miss Stoddart, Officer Finch, and Vera Velvetskin? Sabrina York must have been attracted to the place, for her footprints grease.
