There was no calendar in sight, and he could find no newspapers or dated periodicals, but he knew that it was prior to July 18, 1946. On that day, his fourteenth birthday, his father had given him a light .22 rifle, and it had been hung on a pair of rustic forks on the wall. It was not there now, nor ever had been. On the table, he saw a boys' book of military aircraft, with a clean, new dustjacket; the flyleaf was inscribed: _To Allan Hartley, from his father, on his thirteenth birthday, 7/18 '45._ Glancing out the window at the foliage on the trees, he estimated the date at late July or early August, 1945; that would make him just thirteen. His clothes were draped on a chair beside the bed. Stripping off his pajamas, he donned shorts, then sat down and picked up a pair of lemon-colored socks, which he regarded with disfavor. As he pulled one on, a church bell began to clang. St. Boniface, up on the hill, ringing for early Mass; so this was Sunday. He paused, the second sock in his hand. There was no question that his present environment was actual. Yet, on the other hand, he possessed a set of memories completely at variance with it. Now, suppose, since his environment were not an illusion, everything else were? Suppose all these troublesome memories were no more than a dream? Why, he was just little Allan Hartley, safe in his room on a Sunday morning, badly scared by a nightmare! Too much science fiction, Allan; too many comic books! That was a wonderfully comforting thought, and he hugged it to him contentedly. It lasted all the while he was buttoning up his shirt and pulling on his pants, but when he reached for his shoes, it evaporated. Ever since he had wakened, he realized, he had been occupied with thoughts utterly incomprehensible to any thirteen-year-old; even thinking in words that would have been so much Sanscrit to himself at thirteen. He shook his head regretfully. The just-a-dream hypothesis went by the deep six. He picked up the second shoe and glared at it as though it were responsible for his predicament. He was going to have to be careful. An unexpected display of adult characteristics might give rise to some questions he would find hard to answer credibly. Fortunately, he was an only child; there would be no brothers or sisters to trip him up. Old Mrs. Stauber, the housekeeper, wouldn't be much of a problem; even in his normal childhood, he had bulked like an intellectual giant in comparison to her. But his father-- Now, there the going would be tough. He knew that shrewd attorney's mind, whetted keen on a generation of lying and reluctant witnesses. Sooner or later, he would forget for an instant and betray himself. Then he smiled, remembering the books he had discovered, in his late 'teens, on his father's shelves and recalling the character of the openminded agnostic lawyer. If he could only avoid the inevitable unmasking until he had a plausible explanatory theory. * * * * *
