“A smoker, Mr. Holmes?” said he, speaking in well-chosen English, with a curious little mincing accent. “Pray take a cigarette. And you, sir? I can recommend them, for I have them especially prepared by Ionides, of Alexandria. He sends me a thousand at a time, and I grieve to say that I have to arrange for a fresh supply every fortnight. Bad, sir, very bad, but an old man has few pleasures. Tobacco and my work⁠—that is all that is left to me.”

Holmes had lit a cigarette and was shooting little darting glances all over the room.

“Tobacco and my work, but now only tobacco,” the old man exclaimed. “Alas! what a fatal interruption! Who could have foreseen such a terrible catastrophe? So estimable a young man! I assure you that, after a few months’ training, he was an admirable assistant. What do you think of the matter, Mr. Holmes?”

“I have not yet made up my mind.”
