“Yes, sir?” said the footman.

“I came in answer to——”

“Quite so, sir,” said the footman. “Lord Linchmere will see you at once in the library.”

Lord Linchmere! I had vaguely heard the name, but could not for the instant recall anything about him. Following the footman, I was shown into a large, book-lined room in which there was seated behind a writing-desk a small man with a pleasant, clean-shaven, mobile face, and long hair shot with grey, brushed back from his forehead. He looked me up and down with a very shrewd, penetrating glance, holding the card which the footman had given him in his right hand. Then he smiled pleasantly, and I felt that externally at any rate I possessed the qualifications which he desired.

“You have come in answer to my advertisement, Dr. Hamilton?” he asked.

“Yes, sir.”

“Do you fulfil the conditions which are there laid down?”

“I believe that I do.”

“You are a powerful man, or so I should judge from your appearance.”

“I think that I am fairly strong.”
