Sir Arthur Conan Doyle: Adventures of Sherlock Holmes

4. ADVENTURE IV. THE BOSCOMBE VALLEY MYSTERY (continued)

"But the mystery?"

"It is solved."

"Who was the criminal, then?"

"The gentleman I describe."

"But who is he?"

"Surely it would not be difficult to find out. This is not such a populous neighborhood."

Lestrade shrugged his shoulders. "I am a practical man," he said, "and I really cannot undertake to go about the country looking for a left-handed gentleman with a game leg. I should become the laughing-stock of Scotland Yard."

"All right," said Holmes quietly. "I have given you the chance. Here are your lodgings. Good-bye. I shall drop you a line before I leave."

He mumbled several words, you understand, but that was all that caught the son's ear. Now from this double point our research must commence, and we will begin it by presuming that what the lad says is absolutely true."

"What of this 'Cooee!' then?"
