THE GIRL IN HIS MIND the U.S. copyright on this publication was renewed.] Every man's mind is a universe with countless places in which he can hide—even from himself! The dance that the chocoletto girl was performing was an expurgated belied her cannibalistic forebears. "You wish a night?" she asked. 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 booting him out into the alley. Instead he found a young girl— He tried to assimilate the information, but could not. Perceiving his "Xenophon," Blake said. "And I suppose Plato too." them. When I grow up I shall be a most well-educated person." white street robe, his eyes moving back and forth from her smooth dark skin to the arras. The incense thickened around him. She noticed the back-and-forth movement of his eyes. "You need not fear enter." her forehead and lay like a lovely flower upon the virginal whiteness of her skin. There was something saintly about her quiet face. When he reached the alley he began to run, and he did not stop running till the chocoletto sector was far behind him. Ideally, a man's mind-country should have been comprised only of the Ever since he had first set foot into his mind, some ten hours ago, they had been on his trail, but for some reason he had been unable to bring himself to go back and find out who they were and what they wanted. Hence he was as vexed with himself as he was with them. materialization, and his quarry's footprints stood out clearly in the 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 had, for twelve years as a psycheye had taught Blake all the tricks. Probably she had taken it for granted that the mere act of hiding out in her tracker's mind was in itself a sufficient guarantee of her safety. After all, she had no way of knowing that he had discovered her presence. Mind-country was as temporally inconsecutive as it was topographically of his mind they existed side by side, surrounded by heterogeneous that constituted Blake's mind-world ceased to be. Ironically, he was of the unconscious materialization had failed to come through. He had never been in his own mind before. Consequently he was more because he was far in her future, but because in his mind-world she was closer so that he could see them more clearly. No, he had made no in real life. Nevertheless a feeling of uneasiness accompanied him when close enough for him to be able to see that two of them were wearing dresses and that the third had on a blue skirt and blouse, and a kepi to match. He gasped. It simply hadn't occurred to him that his pursuers might be women. To his consternation he discovered that he was even more loath to go back and accost them than he had been before. He actually had an impulse to flee. He controlled it and descended the stairs with exaggerated slowness, leaving the house by way of the back door. He picked up Sabrina's trail is a much more complex mechanism than most laymen realize. Guilt feelings aren't reliable criteria. They can stem from false causes—from ridiculous things like a person's inability to accept Wretchedly he turned away. As he did so he saw the three shadows lying at his feet and knew that his pursuers had at last caught up to him. His first reaction when he faced them was amazement. His next reaction was shock. His third was fear. His amazement resulted from recognition. One of the three women arrayed His fear resulted from the realization that his mind-world contained phenomena it had no right to contain—not if he was nearly as one thing. For another, they were aware of him. What were they, then? And what were they doing in his mind? He asked the two questions aloud. You know who we are!" It had taken man a long time to discover that he was a god in his The discovery came about quite by accident. After projecting himself into a patient's memory one day, a psychologist named Trevor suddenly The mountain proved to be an unconscious memory-image out of the patient's mind. After many trials and errors, Trevor managed to get The next logical step was to enter his own mind, and this he also It was inevitable that Trevor should write a book about his discovery and set about founding a new school of psychology. It was equally paper explaining how anyone could enter his or her own mind-world at The method employed an ability that had been evolving in the human mind for millennia—the ability to project oneself into a past moment—or, required before the first transition could be achieved, but once it was achieved, successive transitions became progressively easier. Entering another person's mind-world was of course a more difficult undertaking, and could be achieved only after an intensive study of a certain moment in that person's past. In order to return to the objective world, it was necessary in both cases to locate the most By their very nature, mind-countries were confusing. They existed on these images were subject to the interpretation of the individual creator. As a result they were seldom identical. It was inevitable that sooner or later some criminal would hit upon the idea of hiding out in his own mind-world till the statute of limitations that applied to his particular crime ran out, and it was equally inevitable that others should follow suit. Society's answer was the psyche-police, and the psyche-police hadn't been in action very long before the first private psycheye appeared. Blake was one of a long line of such operators. So far as he knew, the present case represented the first time a criminal had ever hidden out in the pursuer's mind. It would have been a superb stratagem indeed if, shortly after her entry, Sabrina York had not betrayed her presence. For her point of entry she had used ransacked it before moving into a co-terminous memory-image. Even this action wouldn't have given her away, however, if the office remember—the mental picture that had come into his mind had revealed open drawers, scattered papers and a general air of disarray. He had suspected the truth immediately, and when he had seen the woman's handkerchief with the initials "SB" embroidered on it lying by one of the filing cabinets he had known definitely that his quarry was hiding out in his mind. Retiring to his bachelor quarters, he had entered at the same place-time and set off in pursuit. she discovered his presence and was able to locate his most recently materialized place-time before he over-took her, her capture was assured. and it was unlikely that anyone save the few intimate acquaintances 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? The other thing that bothered him was of a much more urgent nature. He had been in enough minds and he had read enough on the subject beings considerably higher on the scale of mind-country evolution than ordinary memory-ghosts. One woman whom he had apprehended in her own mind had created a walking-talking Virgin Mary who watched over these, and other, similar, cases, had to do with mal-adjusted people, They followed him off the campus into a vicarious memory-image of the ecstatic "oh's" and "ah's" they kept giving voice to, the place sufficiently when he had visited it in his youth to have found a place Sabrina York must have been attracted to the place, for her footprints and let herself in the door. reason for Blake to linger. As a matter of fact, the fascination that had brought the place into being had been replaced by an illogical repugnance. But repugnance can sometimes be as compelling a force as fascination, and Blake not only lingered but went inside as well.
