"Not a word. But she will not get far. Sooner or later we shall find her if she does not come forward herself after reading the evening papers." "She will never come forward." "I am not so sure. Something not a little peculiar happened at the museum after you left. We had Reynolds up, and he made a most careful examination of that bow for finger-prints. He did not find any. But fortune favored us in another way almost as good." "Now you interest _me_." "We had brought the bow into the Curator's office, and it lay on the long table in the middle of the room. I had been looking it over (this was after Reynolds had gone, of course) and had already noted a certain defect in it, when on chancing to look up, my eyes fell on a mirror hanging in a closet the door of which stood wide open. A face was visible in it--a very white face which altered under my scrutiny into a semblance more natural. It was that of Correy--you remember Correy, one of the assistants, and an honest fellow enough, but more troubled at this moment than I had ever seen him. What could have happened? "Wheeling quickly about, I caught him just as he started to go. He had openly declared that he did not know this bow; but it was evident that he did, and I did not hesitate to say so. Taken unawares, he could not hide his distress, which he proceeded to explain thus: He did remember the bow, now that he had the opportunity of seeing it closer. He pointed to the nick I had myself noticed and said that owing to this defect the bow had been cast aside, and the last time he had handled it----Here he caught his breath and stopped. Another memory had evidently returned to embarrass him." "Did you succeed in getting him to acknowledge what it was?" "Yes, after I had worked with him for some time. He didn't want to talk. In a moment you will see why. Going back to the time he had seen it before, he said that he had found it in the cellar in an old box, the contents of which he had been pulling over in a search for something very different. Amazed to find it there, he had taken it out, examined it carefully, noted the nick I mentioned and tossed it back again into the box. This he told, but reluctantly. "Why reluctantly, I was soon to find out. He was not alone in the cellar. The shadow of some person at his back had fallen across the lid of the box as he was closing it. He did not recognize the shadow and had not given it at the time a second thought, but the remembrance of it came back vividly when he saw the bow lying before him and realized the part it had played in the morning's tragedy. Was it because he knew that only a person actively connected with the museum would have access to that part of the cellar? I asked. I did not expect an answer, and I did not get it. We looked at each other for a moment, then I let him go." A momentary silence, which the Inspector broke by saying:
