McMurdo shrugged his shoulders. “You were too soft for the job,” said he. “You are the wrong sort for such work.”

“I had a conscience and a religion; but they made me a criminal among them. I was chosen for a job. If I backed down I knew well what would come to me. Maybe I’m a coward. Maybe it’s the thought of my poor little woman and the children that makes me one. Anyhow I went. I guess it will haunt me forever.

“It was a lonely house, twenty miles from here, over the range yonder. I was told off for the door, same as you were last night. They could not trust me with the job. The others went in. When they came out their hands were crimson to the wrists. As we turned away a child was screaming out of the house behind us. It was a boy of five who had seen his father murdered. I nearly fainted with the horror of it, and yet I had to keep a bold and smiling face; for well I knew that if I did not it would be out of my house that they would come next with their bloody hands and it would be my little Fred that would be screaming for his father.

“But I was a criminal criminal then, part sharer in a murder, lost forever in this world, and lost also in the next. I am a good Catholic; but the priest would have no word with me when he heard I was a Scowrer, and I am excommunicated from my faith. That’s how it stands with me. And T see you going down the same road, and I ask you what the end is to be. Are you ready to be a cold-blooded murderer also, or can we do anything to stop it?”

“What would you do?” asked McMurdo abruptly. “You would not inform?”

“God forbid!” cried Morris. “Sure, the very thought would cost me my life.”

“That’s well,” said McMurdo. “I’m thinking that you are a weak man and that you make too much of the matter.”

“Too much! Wait till you have lived here longer. Look down the valley! See the cloud of a hundred chimneys that overshadows it! I tell you that the cloud of murder hangs thicker and lower than that over the heads of the people. It is the Valley of Fear, the Valley of Death. The terror is in the hearts of the people from the dusk to the dawn. Wait, young man, and you will learn for yourself.”

“Well, I’ll let you know what I think when I have seen more,” said McMurdo carelessly. “What is very clear is that you are not the man for the place, and that the sooner you sell out — if you only get a dime a dollar for what the business is worth — the better it will be for you. What you have said is safe with me; but, by Gar! if I thought you were an informer —”

“No, no!” cried Morris piteously.

“Well, let it rest at that. I’ll bear what you have said in mind, and maybe some day I’ll come back to it. I expect you meant kindly by speaking to me like this. Now I’ll be getting home.”

“One word before you go,” said Morris. “We may have been seen together. They may want to know what we have spoken about.”

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.”
