“This is clean beyond me, Mr. Holmes. We saw you when we returned from Tunbridge Wells last night, and you were in general agreement with our results. What has happened since then to give you a completely new idea of the case?”

“Well, since you ask me, I spent, as I told you that I would, some hours last night at the Manor House.”

“Well, what happened?”

“Ah, I can only give you a very general answer to that for the moment. By the way, I have been reading a short but clear and interesting account of the old building, purchasable at the modest sum of one penny from the local tobacconist.”

Here Holmes drew a small tract, embellished with a rude engraving of the ancient Manor House, from his waistcoat pocket.

“It immensely adds to the zest of an investigation, my dear Mr. Mac, when one is in conscious sympathy with the historical atmosphere of one’s surroundings. Don’t look so impatient; for I assure you that even so bald an account as this raises some sort of picture of the past in one’s mind. Permit me to give you a sample. ‘Erected in the fifth year of the reign of James I, and standing upon the site of a much older building, the Manor House of Birlstone presents one of the finest surviving examples of the moated Jacobean residence—’”

“You are making fools of us, Mr. Holmes!”

“Tut, tut, Mr. Mac!—the first sign of temper I have detected in you. Well, I won’t read it verbatim, since you feel so strongly upon the subject. But when I tell you that there is some account of the taking of the place by a parliamentary colonel in 1644, of the concealment of Charles for several days in the course of the Civil War, and finally of a visit there by the second George, you will admit that there are various associations of interest connected with this ancient house.”

“I don’t doubt it, Mr. Holmes; but that is no business of ours.”

“Is it not? Is it not? Breadth of view, my dear Mr. Mac, is one of the essentials of our profession. The interplay of ideas and the oblique uses of knowledge are often of extraordinary interest. You will excuse these remarks from one who, though a mere connoisseur of crime, is still rather older and perhaps more experienced than yourself.”

“I’m the first to admit that,” said the detective heartily. “You get to your point, I admit; but you have such a deuced round-the-corner way of doing it.”
