So it had been in the case of Semper Idem. The mystery of the man had not appealed to him, nor had his silence and the veiled romance which the yellow reporters had so sensationally and so fruitlessly exploited in divers Sunday editions. But Semper Idem's throat had been cut. That was the point. That was where his interest had centred. Cut from ear to ear, and not one surgeon in a thousand to give a snap of the fingers for his chance of recovery. But, thanks to the swift municipal ambulance service and to Doctor Bicknell, he had been dragged back into the world he had sought to leave. The Doctor's co-workers had shaken their heads when the case was brought in. Impossible, they said. Throat, windpipe, jugular, all but actually severed, and the loss of blood frightful. As it was such a foregone conclusion, Doctor Bicknell had employed methods and done things which made them, even in their professional capacities, shudder. And lo! the man had recovered. So, on this morning that Semper Idem was to leave the hospital, hale and hearty, Doctor Bicknell's geniality was in nowise disturbed by the steward's report, and he proceeded cheerfully to bring order out of the chaos of a child's body which had been ground and crunched beneath the wheels of an electric car. As many will remember, the case of Semper Idem aroused a vast deal of unseemly yet highly natural curiosity. He had been found in a slum lodging, with throat cut as aforementioned, and blood dripping down upon the inmates of the room below and disturbing their festivities. He had evidently done the deed standing, with head bowed forward that he might gaze his last upon a photograph which stood on the table propped against a candlestick. It was this attitude which had made it possible for Doctor Bicknell to save him. So terrific had been the sweep of the razor that had he had his head thrown back, as he should have done to have accomplished the act properly, with his neck stretched and the elastic vascular walls distended, he would have of a certainty well-nigh decapitated himself. At the hospital, during all the time he travelled the repugnant road back to life, not a word had left his lips. Nor could anything be learned of him by the sleuths detailed by the chief of police. Nobody knew him, nor had ever seen or heard of him before. He was strictly, uniquely, of the present. His clothes and surroundings were those of the lowest labourer, his hands the hands of a gentleman. But not a shred of writing was discovered, nothing, save in one particular, which would serve to indicate his past or his position in life.
