“We have it all here,” said Gregson, pointing to a litter of objects upon one of the bottom steps of the stairs. “A gold watch, No. 97163, by Barraud, of London. Gold Albert chain, very heavy and solid. Gold ring, with masonic device. Gold pin—bull-dog’s head, with rubies as eyes. Russian leather card-case, with cards of Enoch J. Drebber of Cleveland, corresponding with the E. J. D. upon the linen. No purse, but loose money to the extent of seven pounds thirteen. Pocket edition of Boccaccio’s Decameron, with name of Joseph Stangerson upon the fly-leaf. Two letters—one addressed to E. J. Drebber and one to Joseph Stangerson.”

“At what address?”

“American Exchange, Strand—to be left till called for. They are both from the Guion Steamship Company, and refer to the sailing of their boats from Liverpool. It is clear that this unfortunate man was about to return to New York.”

“Have you made any inquiries as to this man, Stangerson?”

“I did it at once, sir,” said Gregson. “I have had advertisements sent to all the newspapers, and one of my men has gone to the American Exchange, but he has not returned yet.”

“Have you sent to Cleveland?”

“We telegraphed this morning.”

“How did you word your inquiries?”

“We simply detailed the circumstances, and said that we should be glad of any information which could help us.”

“You did not ask for particulars on any point which appeared to you to be crucial?”

“I asked about Stangerson.”

“Nothing else? Is there no circumstance on which this whole case appears to hinge? Will you not telegraph again?”

“I have said all I have to say,” said Gregson, in an offended voice.

Sherlock Holmes chuckled to himself, and appeared to be about to make some remark, when Lestrade, who had been in the front room while we were holding this conversation in the hall, reappeared upon the scene, rubbing his hands in a pompous and self-satisfied manner.

“Mr. Gregson,” he said, “I have just made a discovery of the highest importance, and one which would have been overlooked had I not made a careful examination of the walls.”

The little man’s eyes sparkled as he spoke, and he was evidently in a state of suppressed exultation at having scored a point against his colleague.

“Come here,” he said, bustling back into the room, the atmosphere of which felt clearer since the removal of its ghastly inmate. “Now, stand there!”

He struck a match on his boot and held it up against the wall.

“Look at that!” he said, triumphantly.
