Not many weeks ago, on a street corner in the village of Pascoag, Rhode Island, a tall, heavily built, and wholesome-looking pedestrian furnished much speculation by a singular lapse of behaviour. He had, it appears, been descending the hill by the road from Chepachet; and encountering the compact section, had turned to his left into the main thoroughfare where several modest business blocks convey a touch of the urban. At this point, without visible provocation, he committed his astonishing lapse; staring queerly for a second at the tallest of the buildings before him, and then, with a series of terrified, hysterical shrieks, breaking into a frantic run which ended in a stumble and fall at the next crossing. Picked up and dusted off by ready hands, he was found to be conscious, organically unhurt, and evidently cured of his sudden nervous attack. He muttered some shamefaced explanations involving a strain he had undergone, and with downcast glance turned back up the Chepachet road, trudging out of sight without once looking behind him. It was a strange incident to befall so large, robust, normal-featured, and capable-looking a man, and the strangeness was not lessened by the remarks of a bystander who had recognised him as the boarder of a well-known dairyman on the outskirts of Chepachet.

He was, it developed, a New York police detective named Thomas F. Malone, now on a long leave of absence under medical treatment after some disproportionately arduous work on a gruesome local case which accident had made dramatic. There had been a collapse of several old brick buildings during a raid in which he had shared, and something about the wholesale loss of life, both of prisoners and of his companions, had peculiarly appalled him. As a result, he had acquired an acute and anomalous horror of any buildings even remotely suggesting the ones which had fallen in, so that in the end mental specialists forbade him the sight of such things for an indefinite period.
