Sir Arthur Conan Doyle: The Return of Sherlock Holmes

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

"Yes," said I. "You have not made it clear what was Colonel Moran's motive in murdering the Honourable Ronald Adair."

"Ah! my dear Watson, there we come into those realms of conjecture where the most logical mind may be at fault. Each may form his own hypothesis upon the present evidence, and yours is as likely to be correct as mine."

"You have formed one, then?"

"I think that it is not difficult to explain the facts. It came out in evidence that Colonel Moran and young Adair had between them won a considerable amount of money. Now, Moran undoubtedly played foul -- of that I have long been aware. I believe that on the day of the murder Adair had discovered that Moran was cheating. Very likely he had spoken to him privately, and had threatened to expose him unless he voluntarily resigned his membership of the club and promised not to play cards again. It is unlikely that a youngster like Adair would at once make a hideous scandal by exposing a well-known man so much older than himself. Probably he acted as I suggest. The exclusion from his clubs would mean ruin to Moran, who lived by his ill-gotten card gains. He therefore murdered Adair, who at the time was endeavouring to work out how much money he should himself return, since he could not profit by his partner's foul play. He locked the door lest the ladies should surprise him and insist upon knowing what he was doing with these names and coins. Will it pass?"

"I have no doubt that you have hit upon the truth."

"It will be verified or disproved at the trial. Meanwhile, come what may, Colonel Moran will trouble us no more, the famous air-gun of Von Herder will embellish the Scotland Yard Museum, and once again Mr. Sherlock Holmes is free to devote his life to examining those interesting little problems which the complex life of London so plentifully presents."
