“Man, this is getting past a joke!” cried MacDonald, rising angrily from his chair.

“Well, well, spend the day as you like,” said Holmes, patting him cheerfully upon the shoulder. “Do what you like and go where you will, but meet me here before dusk without fail — without fail, Mr. Mac.”

“That sounds more like sanity.”

“All of it was excellent advice; but I don’t insist, so long as you are here when I need you. But now, before we part, I want you to write a note to Mr. Barker.”

“Well?”

“I’ll dictate it, if you like. Ready?

“Dear Sir:

“It has struck me that it is our duty to drain the moat, in the hope that we may find some —”

“It’s impossible,” said the inspector. “I’ve made inquiry.”

“Tut, tut! My dear sir, please do what I ask you.”

“Well, go on.”

“— in the hope that we may find something which may bear upon our investigation. I have made arrangements, and the workmen will be at work early to-morrow morning diverting the stream —”

“Impossible!”

“— diverting the stream; so I thought it best to explain matters beforehand.

Now sign that, and send it by hand about four o’clock. At that hour we shall meet again in this room. Until then we may each do what we like; for I can assure you that this inquiry has come to a definite pause.”

Evening was drawing drawing in when we reassembled. Holmes was very serious in his manner, myself curious, and the detectives obviously critical and annoyed.

“Well, gentlemen,” said my friend gravely, “I am asking you now to put everything to the test with me, and you will judge for yourselves whether the observations I have made justify the conclusions to which I have come. It is a chill evening, and I do not know how long our expedition may last; so I beg that you will wear your warmest coats. It is of the first importance that we should be in our places before it grows dark; so with your permission we shall get started at once.”

We passed along the outer bounds of the Manor House park until we came to a place where there was a gap in the rails which fenced it. Through this we slipped, and then in the gathering gloom we followed Holmes until we had reached a shrubbery which lies nearly opposite to the main door and the drawbridge. The latter had not been raised. Holmes crouched down behind the screen of laurels, and we all three followed his example.

“Well, what are we to do now?” asked MacDonald with some gruffness.

“Possess our souls in patience and make as little noise as possible,” Holmes answered.

“What are we here for at all? I really think that you might treat us with more frankness.”

Holmes laughed. “Watson insists that I am the dramatist in real life,” said he. “Some touch of the artist wells up within me, and calls insistently for a well-staged performance. Surely our profession, Mr. Mac, would be a drab and sordid one if we did not sometimes set the scene so as to glorify our results. The blunt accusation, the brutal tap upon the shoulder — what can one make of such a denouement? But the quick inference, the subtle trap, the clever forecast of coming events, the triumphant vindication of bold theories — are these not the pride and the justification of our life’s work? At the present moment you thrill with the glamour of the situation and the anticipation of the hunt. Where would be that thrill if I had been as definite as a timetable? I only ask a little patience, Mr. Mac, and all will be clear to you.”

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.”
