"I'll tell you whether Lord Loudwater is alive or not. Don't let any one cross the threshold, Perkins," said Mr. Flexen, with quiet decision. Perkins laid a hand on the doctor's arm, and the doctor said: "A nice way of doing things! Arbuthnot would have given his first attention to his lordship!" "I'm going to," said Mr. Flexen quietly. He went to the dead man, looked in his pale face, lifted his hand, let it fall, and said: "Been dead hours." Then he examined carefully the position of the knife. He was more than a minute over it. Then he drew it gingerly from the wound by the ring at the end of it. It was one of these Swedish knives, the blades of which are slipped into the handle when they are not being used. "I think that's the knife that lay, open, in the big ink-stand in the library. We used it as a paper-knife, and to cut string with," said Mr. Manley, who was watching him with most careful attention. "It may have some evidence on the handle," said Mr. Flexen, still holding it by the ring, and he drove the point of it into the pad of blotting paper on which Mr. Manley had been wont to write letters at the murdered man's dictation. "And how am I to tell whether the wound was self-inflicted, or not?" cried the doctor in an aggrieved tone. "If you will get some of the servants, you can remove the body to any room convenient and make your examination. It's a clean stab into the heart, and it looks to me as if the person who used that knife had some knowledge of anatomy. Most people who strike for the heart get the middle of the left lung," said Mr. Flexen. So saying, he gently drew the easy chair, in which the body was huddled, nearer the door by its back. Mr. Manley bade Holloway fetch Wilkins and two of the grooms, and then, eager for hints of the actions of a detective, so useful to a dramatist, gave all his attention again to the proceedings of Mr. Flexen, who was down on one knee on the spot in which the chair had stood, studying the carpet round it. He rose and walked slowly towards the door which opened into the library, paused on the threshold to bid Perkins examine the chair and the clothes of the murdered man, and went into the library. He was still in it when the footman and the grooms lifted the body of Lord Loudwater out of the chair, and carried it up to his bedroom. Mr. Manley stayed on the threshold of the smoking-room. His interest in the doings of Mr. Flexen forbade him leaving it to superintend decorously the removal of the body.
