"'That's very likely, sir,' the detective answered, coolly. 'I turned up Joseph Wilmot's own history while I was making myself acquainted with the details of this murder. He was transported thirty years ago for forgery: he made a bold attempt at escape, but he was caught in the act, and removed to Norfolk Island. He was one of the cleverest chaps at counterfeiting any man's handwriting that was ever tried at the Old Bailey. He was known as one of the most daring scoundrels that ever stepped on board a convict-ship; a clever villain, and a bold one, but not without some touches of good in him, I'm told. At Norfolk Island he worked so hard and behaved so well that he got set free before he had served half his time. He came back to England, and was seen about London, and was suspected of being concerned in all manner of criminal offences, from card-sharping to coining, but nothing was ever brought home to him. I believe he tried to make an honest living, but couldn't: the brand of the gaol-bird was upon him; and if he ever did get a chance, it was taken away from him before the sincerity of any apparent reformation had been tested. This is his history, and the history of many other men like him.' "And Margaret was the daughter of this man. An inexpressible feeling of melancholy took possession of me as I thought of this. I understood everything now. This noble girl had heroically put away from her the one chance of bright and happy life, rather than bring upon her husband the foul taint of her father's crime. I could understand all now. I looked back at the white face, rigid in its speechless agony; the fixed, dilated eyes; and I pictured to myself the horror of that scene at Maudesley Abbey, when the father and daughter stood opposite to each other, and Margaret Wilmot discovered _why_ the murderer had persistently hidden himself from her. "The mystery of my betrothed wife's renunciation of my love had been solved; but the discovery was so hideous that I looked back now and regretted the time of my ignorance and uncertainty. Would it not have been better for me if I had let Margaret Wilmot go her own way, and carry out her sublime scheme of self-sacrifice? Would it not have been better to leave the dark secret of the murder for ever hidden from all but that one dread Avenger whose judgments reach the sinner in his remotest hiding-place, and follow him to the grave? Would it not have been better to do this? "No! my own heart told me the argument was false and cowardly. So long as man deals with his fellow-man, so long as laws endure for the protection of the helpless and the punishment of the wicked, the course of justice must know no hindrance from any personal consideration.
