"This is most interesting," Sabatini declared, carefully marking the place in his book and laying it aside. "What did you find there?" "A dead man," Arnold answered, "a murdered man!" "You are joking!" Sabatini protested. "He had been struck on the forehead," Arnold continued, "and dragged half under the couch. Only his arm was visible at first. We had to move the couch to discover him." "Do you know who he was?" Sabatini asked. "No one had any idea," Arnold answered. "I think that I was the only one who had ever seen him before. The night I dined at Mr. Weatherley's for the first time and met you, I was with Mrs. Weatherley in her room, and I saw that man steal up to the window as though he were going to break in." "This is most interesting," Sabatini declared. "Evidently a dangerous customer. But you say that you found him dead. Who killed him?" "There was no one there who could say," Arnold declared. "There were no servants in that part of the house, there had been no visitors, and Mr. Weatherley had been in bed since half-past nine. We telephoned for a doctor, and we fetched Mr. Weatherley out of bed. Then a strange thing happened. We took Mr. Weatherley to the room, which we had left for less than five minutes, and there was no one there. The man had been carried away." "Really," Sabatini protested, "your story gets more interesting every moment. Don't tell me that this is the end!" "It is not," Arnold replied. "It seemed then as though there were nothing more to be done. Evidently he had either been only stunned and had got up and left the room by the window, or he had accomplices who had fetched him away. Mr. Weatherley was very much annoyed with us and we had to make excuses to the doctor. Then I left." "Well?" Sabatini said. "You left. You didn't come straight here?" Arnold shook his head. "When I got into the road, I could see that there was a policeman on duty on the other side of the way, and quite a number of people moving backwards and forwards all the time. It seemed impossible that they could have brought him out there if he had been fetched away. Something made me remember what I had noticed on the evening I had dined there--that there was a small empty house next door. I walked back up the drive of Pelham Lodge, turned into the shrubbery, and there I found that there was an easy way into the next garden. I made my way to the back of the house. I saw lights in the kitchen. There were three of his companions there, and the dead man. They were trying to see if they could revive him. I looked through a chink in the boarded window and I saw everything." "Trying to revive him," Sabatini remarked. "Evidently there was some doubt as to his being dead, then."
