The two Cunninghams were bending over the prostrate figure of Sherlock Holmes, the younger clutching his throat with both hands, while the elder seemed to be twisting one of his wrists. In an instant the three of us had torn them away from him, and Holmes staggered to his feet, very pale, and evidently greatly exhausted.

“Arrest these men, Inspector!” he gasped.

“On what charge?”

“That of murdering their coachman, William Kirwan!”

April 26, 1898: Holmes fought with Jack Woodley. [SOLI]

He had a fine flow of language, and his adjectives were very vigorous. He ended a string of abuse by a vicious back-hander which I failed to entirely avoid. The next few minutes were delicious. It was a straight left against a slogging ruffian. I emerged as you see me. Mr. Woodley went home in a cart.
