“It seemed to me that my sudden appearance might shake his nerves and lead him to say something unguarded. The Boots volunteered to show me the room: it was on the second floor, and there was a small corridor leading up to it. The Boots pointed out the door to me, and was about to go downstairs again when I saw something that made me feel sickish, in spite of my twenty years’ experience. From under the door there curled a little red ribbon of blood, which had meandered across the passage and formed a little pool along the skirting at the other side. I gave a cry, which brought the Boots back. He nearly fainted when he saw it. The door was locked on the inside, but we put our shoulders to it, and knocked it in. The window of the room was open, and beside the window, all huddled up, lay the body of a man in his nightdress. He was quite dead, and had been for some time, for his limbs were rigid and cold. When we turned him over, the Boots recognized him at once as being the same gentleman who had engaged the room under the name of Joseph Stangerson. The cause of death was a deep stab in the left side, which must have penetrated the heart. And now comes the strangest part of the affair. What do you suppose was above the murdered man?”

I felt a creeping of the flesh, and a presentiment of coming horror, even before Sherlock Holmes answered.

“The word RACHE, written in letters of blood,” he said.

“That was it,” said Lestrade, in an awe-struck voice; and we were all silent for a while.

There was something so methodical and so incomprehensible about the deeds of this unknown assassin, that it imparted a fresh ghastliness to his crimes. My nerves, which were steady enough on the field of battle tingled as I thought of it.

“The man was seen,” continued Lestrade. “A milk boy, passing on his way to the dairy, happened to walk down the lane which leads from the mews at the back of the hotel. He noticed that a ladder, which usually lay there, was raised against one of the windows of the second floor, which was wide open. After passing, he looked back and saw a man descend the ladder. He came down so quietly and openly that the boy imagined him to be some carpenter or joiner at work in the hotel. He took no particular notice of him, beyond thinking in his own mind that it was early for him to be at work. He has an impression that the man was tall, had a reddish face, and was dressed in a long, brownish coat. He must have stayed in the room some little time after the murder, for we found blood-stained water in the basin, where he had washed his hands, and marks on the sheets where he had deliberately wiped his knife.”

I glanced at Holmes on hearing the description of the murderer, which tallied so exactly with his own. There was, however, no trace of exultation or satisfaction upon his face.
