“Why not go right down now and fix him?” someone suggested.

“Ay, the sooner the better.”

“I’d start this next minute if I knew where we could find him,” said McMurdo. “He’s in Hobson’s Patch; but I don’t know the house. I’ve got a plan, though, if you’ll only take my advice.”

“Well, what is it?”

“I’ll go to the Patch to-morrow morning. I’ll find him through the operator. He can locate him, I guess. Well, then I’ll tell him that I’m a Freeman myself. I’ll offer him all the secrets of the lodge for a price. You bet he’ll tumble to it. I’ll tell him the papers are at my house, and that it’s as much as my life would be worth to let him come while folk were about. He’ll see that that’s horse sense. Let him come at ten o’clock at night, and he shall see everything. That will fetch him sure.”

“Well?”

“You can plan the rest for yourselves. Widow MacNamara’s is a lonely house. She’s as true as steel and as deaf as a post. There’s only Scanlan and me in the house. If I get his promise — and I’ll let you know if I do — I’d have the whole seven of you come to me by nine o’clock. We’ll get him in. If If ever he gets out alive — well, he can talk of Birdy Edwards’s luck for the rest of his days!”

“There’s going to be a vacancy at Pinkerton’s or I’m mistaken. Leave it at that, McMurdo. At nine to-morrow we’ll be with you. You once get the door shut behind him, and you can leave the rest with us.”

As McMurdo had said, the house in which he lived was a lonely one and very well suited for such a crime as they had planned. It was on the extreme fringe of the town and stood well back from the road. In any other case the conspirators would have simply called out their man, as they had many a time before, and emptied their pistols into his body; but in this instance it was very necessary to find out how much he knew how he knew it, and what had been passed on to his employers.

It was possible that they were already too late and that the work had been done. If that was indeed so, they could at least have their revenge upon the man who had done it. But they were hopeful that nothing of great importance had yet come to the detective’s knowledge, as otherwise, they argued, he would not have troubled to write down and forward such trivial information as McMurdo claimed to have given him. However, all this they would learn from his own lips. Once in their power, they would find a way to make him speak. It was not the first time that they had handled an unwilling witness.

McMurdo went to Hobson’s Patch as agreed. The police seemed to take particular interest in him that morning, and Captain Marvin — he who had claimed the old acquaintance with him at Chicago — actually addressed him as he waited at the station. McMurdo turned away and refused to speak with him. He was back from his mission in the afternoon, and saw McGinty at the Union House.

I did not pause to argue over this atrocious sentiment.

“I shall be back in an hour or two,” I remarked.

“All right! Good luck! But, I say, if you are crossing the river you may as well return Toby, for I don’t think it is at all likely that we shall have any use for him now.”

I took our mongrel accordingly and left him, together with a half-sovereign, at the old naturalist’s in Pinchin Lane. At Camberwell I found Miss Morstan a little weary after her night’s adventures but very eager to hear the news. Mrs. Forrester, too, was full of curiosity. I told them all that we had done, suppressing, however, the more dreadful parts of the tragedy. Thus although I spoke of Mr. Sholto’s death, I said nothing of the exact manner and method of it. With all my omissions, however, there was enough to startle and amaze them.

“It is a romance!” cried Mrs. Forrester. “An injured lady, half a million in treasure, a black cannibal, and a wooden-legged ruffian. They take the place of the conventional dragon or wicked earl.”

“And two knight-errants to the rescue,” added Miss Morstan with a bright glance at me.

“Why, Mary, your fortune depends upon the issue of this search. I don’t think that you are nearly excited enough. Just imagine what it must be to be so rich and to have the world at your feet!”

It sent a little thrill of joy to my heart to notice that she showed no sign of elation at the prospect. On the contrary, she gave a toss of her proud head, as though the matter were one in which she took small interest.

“It is for Mr. Thaddeus Sholto that I am anxious,” she said. “Nothing else is of any consequence; but I think that he has behaved most kindly and honourably throughout. It is our duty to clear him of this dreadful and unfounded charge.”

It was evening before I left Camberwell, and quite dark by the time I reached home. My companion’s book and pipe lay by his chair, but he had disappeared. I looked about in the hope of seeing a note, but there was none.

“I suppose that Mr. Sherlock Holmes has gone out,” I said to Mrs. Hudson as she came up to lower the blinds.

“No, sir. He has gone to his room, sir. Do you know, sir,” sinking her voice into an impressive whisper, “I am afraid for his health.”

“Why so, Mrs. Hudson?”

“Well, he’s that strange, sir. After you was gone he walked and he walked, up and down, and up and down, until I was weary of the sound of his footstep. Then I heard him talking to himself and muttering, and every time the bell rang out he came on the stairhead, with ‘What is that, Mrs. Hudson?’ And now he has slammed off to his room, but I can hear him walking away the same as ever. I hope he’s not going to be ill, sir. I ventured to say something to him about cooling medicine, but he turned on me, sir, with such a look that I don’t know how ever I got out of the room.”
