Sir Arthur Conan Doyle: The Return of Sherlock Holmes

1. The Adventure of the Empty House. (continued)

"My collection of M's is a fine one," said he. "Moriarty himself is enough to make any letter illustrious, and here is Morgan the poisoner, and Merridew of abominable memory, and Mathews, who knocked out my left canine in the waiting-room at Charing Cross, and, finally, here is our friend of to-night."

He handed over the book, and I read: "MORAN, SEBASTIAN, COLONEL. Unemployed. Formerly 1st Bengalore Pioneers. Born London, 1840. Son of Sir Augustus Moran, C.B., once British Minister to Persia. Educated Eton and Oxford. Served in Jowaki Campaign, Afghan Campaign, Charasiab (despatches), Sherpur, and Cabul. Author of `Heavy Game of the Western Himalayas,' 1881; `Three Months in the Jungle,' 1884. Address: Conduit Street. Clubs: The Anglo-Indian, the Tankerville, the Bagatelle Card Club."

On the margin was written, in Holmes's precise hand: "The second most dangerous man in London."

"This is astonishing," said I, as I handed back the volume. "The man's career is that of an honourable soldier."

"It is true," Holmes answered. "Up to a certain point he did well. He was always a man of iron nerve, and the story is still told in India how he crawled down a drain after a wounded man-eating tiger. There are some trees, Watson, which grow to a certain height and then suddenly develop some unsightly eccentricity. You will see it often in humans. I have a theory that the individual represents in his development the whole procession of his ancestors, and that such a sudden turn to good or evil stands for some strong influence which came into the line of his pedigree. The person becomes, as it were, the epitome of the history of his own family."

"It is surely rather fanciful."
