"I arrived in Brussels early one morning, having crossed over in the night. At once I drove to the mean hotel where he was lodging. He was sharing a room with a man with whom he had picked up a casual acquaintanceship on the sea voyage between the West Indies and Antwerp. The two men had come over together in the Belgian boat. They looked a pair of young blackguards, but it did not take me very long to be convinced that for some reason best known to himself my brother Arthur had deceived me and that his son Philip was indeed the legitimate and rightful heir to the title which I hold. The papers were authentic and undisputable. This much I knew and that Luke, whom I loved best in all the world, more than any father has ever loved his son, would never be Earl of Radclyffe so long as Philip de Mountford lived. "Men will say that I am an abandoned criminal, and, indeed, it may be so. May God forgive me hereafter, for I killed my brother's son. I pretended to rejoice at his homecoming, and in half an hour had gained his confidence. In the afternoon we went out together and after a short walk we picked up a taxicab. Philip gave the driver the address of a restaurant at which I had asked him to dine with me. I kept carefully in the shadow, so that the man shouldn't see me. Then on the way in the cab, I killed him. When his head was turned away from me, I plunged an old Italian stiletto which I had carried about with me, ever since I had had letters from Philip, straight into his neck. "He died instantly without a groan, and I was sick to death, but I managed to sit quietly beside him until the cab pulled up: then I jumped out and told the chauffeur to drive my friend on to some remote place on the boulevards. "I watched the cab until it was out of sight, then I hailed another, and drove straight to the Gard du Nord, and crossed back to England that night. I threw the stiletto overboard into the sea. I had spent twelve hours in Brussels, and I had killed Philip de Mountford, and made sure that Luke would be Earl of Radclyffe after me. "It was not likely that in their search for the missing criminal who had stabbed an unknown stranger in a cab, the Belgian police would suspect an English peer. The mystery of that crime has remained impenetrable, because nothing was ever known of the stranger who was murdered. At the mean hotel where he lodged no one knew anything about him. Only one person knew and he was silent for purposes of his own. "Before the police searched the unknown stranger's room, the room which he shared with the chance friend whom he had picked up on the Belgian boat, the latter already had found and concealed the papers which would have revealed the identity of the murdered man, if not that of his murderer.
