"What did they take?"

"Well, I don't think there is anything of value missing. I am sure there was nothing in my son's trunks."

"Did the men leave no clue?"

"There was one sheet of paper which I may have torn from the man that I grasped. It was lying all crumpled on the floor. It is in my son's handwriting."

"Which means that it is not of much use," said the Inspector. "Now if it had been in the burglar's——"

"Exactly," said Holmes. "What rugged common sense! None the less, I should be curious to see it."

The Inspector drew a folded sheet of foolscap from his pocket-book.

"I never pass anything, however trifling," said he, with some pomposity. "That is my advice to you, Mr. Holmes. In twenty-five years' experience I have learned my lesson. There is always the chance of finger-marks or something."

Holmes inspected the sheet of paper.

"What do you make of it, Inspector?"
