The Classic Mystery Collection - Arthur Conan Doyle [3249]
"He is coming," said he.
There had been a furtive step past the door. Now it returned. We heard a shuffling sound outside, and then two sharp taps with the knocker. Holmes rose, motioning us to remain seated. The gas in the hall was a mere point of light. He opened the outer door, and then as a dark figure slipped past him he closed and fastened it. "This way!" we heard him say, and a moment later our man stood before us. Holmes had followed him closely, and as the man turned with a cry of surprise and alarm he caught him by the collar and threw him back into the room. Before our prisoner had recovered his balance the door was shut and Holmes standing with his back against it. The man glared round him, staggered, and fell senseless upon the floor. With the shock, his broad-brimmed hat flew from his head, his cravat slipped sown from his lips, and there were the long light beard and the soft, handsome delicate features of Colonel Valentine Walter.
Holmes gave a whistle of surprise.
"You can write me down an ass this time, Watson," said he. "This was not the bird that I was looking for."
"Who is he?" asked Mycroft eagerly.
"The younger brother of the late Sir James Walter, the head of the Submarine Department. Yes, yes; I see the fall of the cards. He is coming to. I think that you had best leave his examination to me."
We had carried the prostrate body to the sofa. Now our prisoner sat up, looked round him with a horror-stricken face, and passed his hand over his forehead, like one who cannot believe his own senses.
"What is this?" he asked. "I came here to visit Mr. Oberstein."
"Everything is known, Colonel Walter," said Holmes. "How an English gentleman could behave in such a manner is beyond my comprehension. But your whole correspondence and relations with Oberstein are within our knowledge. So also are the circumstances connected with the death of young Cadogan West. Let me advise you to gain at least the small credit for repentance and confession, since there are still some details which we can only learn from your lips."
The man groaned and sank his face in his hands. We waited, but he was silent.
"I can assure you," said Holmes, "that every essential is already known. We know that you were pressed for money; that you took an impress of the keys which your brother held; and that you entered into a correspondence with Oberstein, who answered your letters through the advertisement columns of the Daily Telegraph. We are aware that you went down to the office in the fog on Monday night, but that you were seen and followed by young Cadogan West, who had probably some previous reason to suspect you. He saw your theft, but could not give the alarm, as it was just possible that you were taking the papers to your brother in London. Leaving all his private concerns, like the good citizen that he was, he followed you closely in the fog and kept at your heels until you reached this very house. There he intervened, and then it was, Colonel Walter, that to treason you added the more terrible crime of murder."
"I did not! I did not! Before God I swear that I did not!" cried our wretched prisoner.
"Tell us, then, how Cadogan West met his end before you laid him upon the roof of a railway carriage."
"I will. I swear to you that I will. I did the rest. I confess it. It was just as you say. A Stock Exchange debt had to be paid. I needed the money badly. Oberstein offered me five thousand. It was to save myself from ruin. But as to murder, I am as innocent as you."
"What happened, then?"
"He had his suspicions before, and he followed me as you describe. I never knew it until I was at the very door. It was thick fog, and one could not see three yards. I had given two taps and Oberstein had come to the door. The young man rushed up and demanded
