“Stumbled,” he announced positively. “I stumbled once myself, and pitched on my head too, while running up. Them roots do stick out all about the place. Stumbled against the root of a tree and fell, and that thing he was carrying must have gone off right under his chest, I expect.” The echo of the words “Person unknown” repeating itself in his inner consciousness bothered the Chief Inspector considerably. He would have liked to trace this affair back to its mysterious origin for his own information. He was professionally curious. Before the public he would have liked to vindicate the efficiency of his department by establishing the identity of that man. He was a loyal servant. That, however, appeared impossible. The first term of the problem was unreadable—lacked all suggestion but that of atrocious cruelty. Overcoming his physical repugnance, Chief Inspector Heat stretched out his hand without conviction for the salving of his conscience, and took up the least soiled of the rags. It was a narrow strip of velvet with a larger triangular piece of dark blue cloth hanging from it. He held it up to his eyes; and the police constable spoke. “Velvet collar. Funny the old woman should have noticed the velvet collar. Dark blue overcoat with a velvet collar, she has told us. He was the chap she saw, and no mistake. And here he is all complete, velvet collar and all. I don’t think I missed a single piece as big as a postage stamp.” At this point the trained faculties of the Chief Inspector ceased to hear the voice of the constable. He moved to one of the windows for better light. His face, averted from the room, expressed a startled intense interest while he examined closely the triangular piece of broad-cloth. By a sudden jerk he detached it, and _only_ after stuffing it into his pocket turned round to the room, and flung the velvet collar back on the table— “Cover up,” he directed the attendants curtly, without another look, and, saluted by the constable, carried off his spoil hastily.
