The tears came into Mrs Masters' eyes. He had been a bad egg, but he had a good heart at bottom. "That is very sweet of you, Reggie; it will come in very useful. And now to go back for a moment to Cathcart Square. Who was the poor devil who killed himself there? He was as like you as two peas are like each other." "I think we have got to find that out," said Reginald Davis gravely. "Nor, reading the account in the papers, am I quite sure that it was a suicide." "But that was the verdict," interrupted the sister. "I know, but there are peculiar things about the case. Letters addressed to Reginald Davis were found on him; there was a letter signed Reginald Davis, addressed to the Coroner, announcing his intention to commit suicide. Those letters had been placed there by the person who murdered him, and that person who murdered him was somebody who knew me, unless it was the accidental taking of a common name." "But the razor was clutched in his hand, Reggie!" "Quite easy," replied Davis, who, if not a murderer himself, could easily project himself, apparently, into the mind of one. "We will assume, for the moment, it was a man. He cut the poor devil's throat, and then thrust the razor into his stiffening hand, to convey the idea of suicide." "It might be," agreed Mrs Masters. "Well, Carrie, one thing I have fixed on, and it is one of the things for which I have come up. I go to Scotland Yard to-morrow, tell them straight I am Reginald Davis, without a stain upon my character, explain to them that you were misled by a close resemblance. We will have that body exhumed. I am firmly convinced it was a murder." "Let sleeping dogs lie, Reggie," advised Mrs Masters, who had a horror of the law and its subtle ways. "Never mind who was the poor devil who was found there, whether he was murdered or committed suicide. It is no affair of yours." "It is an affair of mine in this way," replied Davis in a dogged tone. "The person who murdered the poor devil, as you call him, knew something about me, and took a liberty with my name." "It served you a good turn, Reggie, anyway." "I know; I admit that. But the murderer did not know he was doing me, thanks to you, a good turn when he killed the other fellow." Mrs Masters thought deeply for a few moments. "Reggie, you have been a very bad egg, I am sure. I shall never guess a quarter of what you have been guilty of." He laid his hand affectionately on her arm. "Well for you, old girl, you can't. That is all past and done with. By the way, that letter found on the poor chap, announcing his intention to commit suicide, did they ask you to identify my handwriting? Of course, the others addressed to him didn't matter much. Anybody could have written them. But my letter was a forgery. Did they ask you to identify that particular letter?"
