The intelligence with which Lestrade greeted us was so momentous and so unexpected that we were all three fairly dumfounded. Gregson sprang out of his chair and upset the remainder of his whisky and water. I stared in silence at Sherlock Holmes, whose lips were compressed and his brows drawn down over his eyes. “Stangerson too!” he muttered. “The plot thickens.”

“It was quite thick enough before,” grumbled Lestrade, taking a chair, “I seem to have dropped into a sort of council of war.”

“Are you—are you sure of this piece of intelligence?” stammered Gregson.

“I have just come from his room,” said Lestrade. “I was the first to discover what had occurred.”

“We have been hearing Gregson’s view of the matter,” Holmes observed. “Would you mind letting us know what you have seen and done?”

“I have no objection,” Lestrade answered, seating himself. “I freely confess that I was of the opinion that Stangerson was concerned in the death of Drebber. This fresh development has shown me that I was completely mistaken. Full of the one idea, I set myself to find out what had become of the secretary. They had been seen together at Euston Station about half-past eight on the evening of the 3rd. At two in the morning Drebber had been found in the Brixton Road. The question which confronted me was to find out how Stangerson had been employed between 8:30 and the time of the crime, and what had become of him afterwards. I telegraphed to Liverpool, giving a description of the man, and warning them to keep a watch upon the American boats. I then set to work calling upon all the hotels and lodginghouses in the vicinity of Euston. You see, I argued that if Drebber and his companion had become separated, the natural course for the latter would be to put up somewhere in the vicinity for the night, and then to hang about the station again next morning.”

“They would be likely to agree on some meeting place beforehand,” remarked Holmes.

“So it proved. I spent the whole of yesterday evening in making inquiries entirely without avail. This morning I began very early, and at eight o’clock I reached Halliday’s Private Hotel, in Little George Street. On my inquiry as to whether a Mr. Stangerson was living there, they at once answered me in the affirmative.

“ ‘No doubt you are the gentleman whom he was expecting,’ they said. ‘He has been waiting for a gentleman for two days.’

“ ‘Where is he now?’ I asked.

“ ‘He is upstairs in bed. He wished to be called at nine.’

“ ‘I will go up and see him at once,’ I said.

“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 Sherock Holmes answered.

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

“That was it,” said Lestrade, in an awestruck 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.

“Did you find nothing in the room which could furnish a clue to the murderer?” he asked.

“Nothing. Stangerson had Drebber’s purse in his pocket, but it seems that this was usual, as he did all the paying. There was eighty-odd pounds in it, but nothing had been taken. Whatever the motives of these extraordinary crimes, robbery is certainly not one of them. There were no papers or memoranda in the murdered man’s pocket, except a single telegram, dated from Cleveland about a month ago, and containing the words, ‘J. H. is in Europe.’ There was no name appended to this message.”

“And there was nothing else?” Holmes asked.

“Nothing of any importance. The man’s novel, with which he had read himself to sleep, was lying upon the bed, and his pipe was on a chair beside him. There was a glass of water on the table, and on the window-sill a small chip ointment box containing a couple of pills.”

Sherlock Holmes sprang from his chair with an exclamation of delight.

“The last link,” he cried, exultantly. “My case is complete.”

The two detectives stared at him in amazement.

“I have now in my hands,” my companion said, confidently, “all the threads which have formed such a tangle. There are, of course, details to be filled in, but I am as certain of all the main facts, from the time that Drebber parted from Stangerson at the station, up to the discovery of the body of the latter, as if I had seen them with my own eyes. I will give you a proof of my knowledge. Could you lay your hand upon those pills?”

“I have them,” said Lestrade, producing a small white box; “I took them and the purse and the telegram, intending to have them put in a place of safety at the police station. It was the merest chance my taking these pills, for I am bound to say that I do not attach any importance to them.”

“Give them here,” said Holmes. “Now, Doctor,” turning to me, “are those ordinary pills?”

They certainly were not. They were of a pearly gray colour, small, round, and almost transparent against the light. “From their lightness and transparency, I should imagine that they are soluble in water,” I remarked.

“Precisely so,” answered Holmes. “Now would you mind going down and fetching that poor little devil of a terrier which has been bad so long, and which the landlady wanted you to put out of its pain yesterday?”

I went downstairs and carried the dog upstairs in my arms. Its laboured breathing and glazing eye showed that it was not far from its end. Indeed, its snow-white muzzle proclaimed that it had already exceeded the usual term of canine existence. I placed it upon a cushion on the rug.
