"Nothing--absolutely nothing. But see here, Mr. Fane; put yourself in my place, in the place of any man. A woman gains admittance to your house and there is murdered. You alone have the key. On the face of it, does not that look as though you alone killed her, else, why the use of your key to let her enter the house? It is lucky for you, as you say, that in full open court, and in the ears of all men, you were able to prove an alibi, else nine out of ten would have suspected you of knowing more than you stated." "I said all I knew." "I am sure of that, sir; and you proved--with the assistance of Mrs. Fane--your innocence. As they say, you leave the court without a stain. All the same, the case is strange. For my part, pending the discovery of the young man who dropped the key, I shall hunt for the woman. In her past life will be found the explanation of her death. I shall let you know how I get on, but I must ask you to also keep me advised of what you see and hear." Fane shrugged his shoulders and took out a cigar. "I shall take no further steps in the matter. Once this woman is buried, and I have left Ajax Villa, the thing will be relegated to obscurity so far as I am concerned." "Well," said Derrick, with a side look, "perhaps that's natural." He then said good-bye to Fane, and went away thoughtfully. Derrick was not a particularly brilliant mortal, as his conduct of the case shows. As the saying goes, he could not see further than his nose. But he certainly wondered in his own mind, if despite the evidence of Mrs. Fane, her husband might not have something to do with the matter. To save his life, to keep him from shame, she might have kept silence. "But it's impossible," said Derrick aloud. "If he was guilty, she would not lie. If the victim had been a man now. But as it was a woman, a jealous creature like Mrs. Fane would certainly not sacrifice herself to save a man who deceived her. No; Fane is guiltless. But who is the culprit? That's the question." And it was a question which Derrick could not answer, though he tried to do so in his blundering way. So the unknown woman was duly buried. Tracey and Fane went to the funeral, and the body was followed by a large concourse of those who wished to see the last of the victim of this mysterious tragedy. Every one agreed that Fane was behaving very well in thus giving the poor wretch decent burial. Fane looked white and worn when the grave was being filled in, and the rumour went round of how ill he had been, and how he had come up from a sick-bed to see this matter through. Several people shook hands with him as he left the cemetery, and he was congratulated on all hands. Then the gates of the burial-ground were closed, and the grave was left to the rain and the sunshine. For all any one present knew, its secret would not be delivered up until the Judgment-day.
