“The reconstruction is easy enough now,” he remarked. “The partition between this sitting room and that little bedroom is only an artificial one--something almost as flimsy as a screen. You see,” he continued, tapping with his knuckles, “you can almost put your hand through it. If you look a little lower down, you will see where an opening has been made. Fluffy Dean was being taken care of by Miss Shaw--staying with her here, even. Miss Dean hears her lover’s voice in this room--hears him pleading with Miss Shaw on he night of the murder. She has been sent home early from the theatre, and it is just possible that she saw or had been told that Austen Abbott had fetched Miss Shaw after the performance and had taken her to supper. She was mad with anger and jealousy. The revolver was there upon the table, with a silver box of cartridges. She possessed herself of it and waited in her room. What she heard proved, at least, her lover’s infidelity. She stood there at her door, waiting. When Austen Abbott comes out, she shoots, throws the revolver at him, closes her door, and goes off into a faint. Perhaps she hears footsteps--a key in the door. At any rate, Captain Sotherst arrives a few minutes later. He finds, half in the hall, half on the threshold of the sitting room, Austen Abbott dead, and Miss Shaw’s revolver by the side of him. If he had been a wise young man, he would have aroused the household. Why he did not do so, we can perhaps guess. He put two and two together a little too quickly. It is certain that he believed that the dead man had been shot by his fiancee. His first thought was to get rid of the revolver. At any rate, he walked down to the street with it in his hand, and was promptly arrested by the policeman who had heard the shot. Naturally he refused to plead, because he believed that Miss Shaw had killed the man, probably in self-defence. She, at first, believed her lover guilty, and when afterwards Fluffy Dean confessed, she, with feminine lack of common sense, was trying to get the girl out of the country before telling the truth. A visit of hers to the office of the steamship company gave me the clue I required.” Lady Mary grasped both his hands. “And Scotland Yard,” she exclaimed, with a withering glance at Dory, “have done their best to hang my brother!” Peter Ruff raised his eyebrows. “Dear Lady Mary,” he said, “remember that it is the business of Scotland Yard to find a man guilty. It is mine, when I am employed for that purpose, to find him innocent. You must not be too hard upon my friend Mr. Dory. He and I seem to come up against each other a little too often, as it is.” “A little too often!” John Dory repeated, softly. “But one cannot tell. Don’t believe, Lady Mary,” he added, “that we ever want to kill an innocent man.” “It is your profession, though,” she answered, “to find criminals--and his,” she added, touching Peter Ruff on the shoulder, “to look for the truth.”
