"Ah, Wilson, I see you have not forgotten the little case in which I had the good fortune to help you?"
"No, sir, indeed I have not. You saved my good name, and perhaps my life."
"My dear fellow, you exaggerate. I have some recollection, Wilson, that you had among your boys a lad named Cartwright, who showed some ability during the investigation."
"Yes, sir, he is still with us."
"Could you ring him up? - thank you! And I should be glad to have change of this five-pound note."
A lad of fourteen, with a bright, keen face, had obeyed the summons of the manager. He stood now gazing with great reverence at the famous detective.
"Let me have the Hotel Directory," said Holmes. "Thank you! Now, Cartwright, there are the names of twenty-three hotels here, all in the immediate neighbourhood of Charing Cross. Do you see?"
"Yes, sir."
"You will visit each of these in turn."
"Yes, sir."
