“Yes, sir, that was the gentleman’s name.”

“Excellent! Tell me where you picked him up and all that occurred.”

“He hailed me at half-past nine in Trafalgar Square. He said that he was a detective, and he offered me two guineas if I would do exactly what he wanted all day and ask no questions. I was glad enough to agree. First we drove down to the Northumberland Hotel and waited there until two gentlemen came out and took a cab from the rank. We followed their cab until it pulled up somewhere near here.”

“This very door,” said Holmes.

“Well, I couldn’t be sure of that, but I dare say my fare knew all about it. We pulled up halfway down the street and waited an hour and a half. Then the two gentlemen passed us, walking, and we followed down Baker Street and along⁠—”

“I know,” said Holmes.

“Until we got three-quarters down Regent Street. Then my gentleman threw up the trap, and he cried that I should drive right away to Waterloo Station as hard as I could go. I whipped up the mare and we were there under the ten minutes. Then he paid up his two guineas, like a good one, and away he went into the station. Only just as he was leaving he turned round and he said: ‘It might interest you to know that you have been driving Mr. Sherlock Holmes.’ That’s how I come to know the name.”

“I see. And you saw no more of him?”

“Not after he went into the station.”
