“You can see for yourself that anyone going out through that open window could reach the front doorstep by taking a long stride. This was clearly what the burglar had done, so I went round and opened the door. Stepping out into the dark, I nearly fell over a dead man, who was lying there. I ran back for a light and there was the poor fellow, a great gash in his throat and the whole place swimming in blood. He lay on his back, his knees drawn up, and his mouth horribly open. I shall see him in my dreams. I had just time to blow on my police-whistle, and then I must have fainted, for I knew nothing more until I found the policeman standing over me in the hall.”

“Well, who was the murdered man?” asked Holmes.
