a certain degree of awe at the thought of invading with police investigation, this home of ancient Knicker-bocker respectability. But once in the room of the missing girl, every consideration fled save that of professional pride and curiosity. For almost at first blush, I saw that whether Mrs. Daniels was correct or not in her surmises as to the manner of the girl's disappearance, the fact that she had disappeared was likely to prove an affair of some importance. For, let me state the facts in the order in which I noticed them. The first thing that impressed me was, that whatever Mrs. Daniels called her, this was no sewing girl's room into which I now stepped. Plain as was the furniture in comparison with the elaborate richness of the walls and ceiling, there were still scattered through the room, which was large even for a thirty-foot house, articles of sufficient elegance to make the supposition that it was the abode of an ordinary seamstress open to suspicion, if no more.

"Yes," returned she; "but there is a passageway leading from my room to hers and it was by that means we entered. There was a chair placed against the door on this side but we easily pushed it away." I stepped to the window and looked out. Ah, it would not be so very difficult for a man to gain the street from that spot in a dark night, for the roof of the newly-erected extension was almost on a level with the window. "Well," said she anxiously,
