he’d fancied that the object was crawling and hitching itself slowly closer across the roofs? That was the way any normal imagination worked. He deliberately chose to disregard the fact that there were reasons for thinking his imagination was by no means a normal one. As he walked home from the elevated, however, he found himself wondering whether the sack was really gone. He seemed to recall a vague, smudgy trail leading across the gravel to the nearer side of the roof. For an instant an unpleasant picture formed in his mind—that of an inky, humped creature crouched behind the nearer parapet, waiting. Then he dismissed the whole subject.
The next time he felt the familiar grating lurch of the car, he caught himself trying not to look out. That angered him. He turned his head quickly. When he turned it back, his compact face was definitely pale. There had only been time for a fleeting rearward glance at the escaping roof. Had he actually seen in silhouette the upper part of a head of some sort peering over the parapet? Nonsense, he told himself. And even if he had seen something, there were a thousand explanations which did not involve the supernatural or even true hallucination. Tomorrow he would take a good look and clear up the whole matter. If necessary, he would visit the roof personally, though he hardly knew where to find it and disliked in any case the idea of pampering a whim of fear.
He did not relish the walk home from the elevated that evening, and visions of the thing disturbed his dreams and were in and out of his mind all next day at the office. It was then that he first began to relieve his nerves by making jokingly serious remarks about the supernatural to Miss Millick, who seemed properly mystified. It was on the same day, too, that he became aware of a growing antipathy to grime and soot. Everything he touched seemed gritty, and he found himself mopping and wiping at his desk like an old lady with a morbid fear of germs. He reasoned that there was no real change in his office, and that he’d just now become sensitive to the dirt that had always been there, but there was no denying an increasing nervousness. Long before the car reached the curve, he was straining his eyes through the murky twilight determined to take in every detail.
Afterward he realized that he must have given a muffled cry of some sort, for the man beside him looked at him curiously, and the woman ahead gave him an unfavorable stare. Conscious of his own pallor and uncontrollable trembling, he stared back at them hungrily, trying to regain the feeling of security he had completely lost. They were the usual reassuringly wooden-faced people everyone rides home with on the elevated. But suppose he had pointed out to one of them what he had seen—that sodden, distorted face of sacking and coal dust, that boneless paw which waved back and forth, unmistakably in his direction, as if reminding him of a future appointment—he involuntarily shut his eyes tight. His thoughts were racing ahead to tomorrow evening. He pictured this same windowed oblong of light and packed humanity surging around the curve—then an opaque monstrous form leaping out from the roof in a parabolic swoop—an unmentionable face pressed close against the window, smearing it with wet coal dust—huge paws fumbling sloppily at the glass.
Somehow he managed to turn off his wife’s anxious inquiries. Next morning he reached a decision and made an appointment for that evening with a psychiatrist a friend had told him about. It cost him a considerable effort, for Catesby had a peculiarly great and very well-grounded distaste for anything dealing with psychological abnormality. Visiting a psychiatrist meant raking up an episode in his past which he had never fully described even to his wife and which Miss Millick only knew of as “something impressively abnormal about Mr. Wran’s childhood.” Once he had made the decision, however, he felt considerably relieved.
