“Hotel Cosmopolitan Jewel Robbery. John Horner, 26, plumber, was brought up upon the charge of having upon the 22d inst., abstracted from the jewel-case of the Countess of Morcar the valuable gem known as the blue carbuncle. James Ryder, upper-attendant at the hotel, gave his evidence to the effect that he had shown Horner up to the dressing-room of the Countess of Morcar upon the day of the robbery in order that he might solder the second bar of the grate, which was loose. He had remained with Horner some little time, but had finally been called away. On returning, he found that Horner had disappeared, that the bureau had been forced open, and that the small morocco casket in which, as it afterwards transpired, the Countess was accustomed to keep her jewel, was lying empty upon the dressing-table. Ryder instantly gave the alarm, and Horner was arrested the same evening; but the stone could not be found either upon his person or in his rooms. Catherine Cusack, maid to the Countess, deposed to having heard Ryder’s cry of dismay on discovering the robbery, and to having rushed into the room, where she found matters as described by the last witness. Inspector Bradstreet, B division, gave evidence as to the arrest of Horner, who struggled frantically, and protested his innocence in the strongest terms. Evidence of a previous conviction for robbery having been given against the prisoner, the magistrate refused to deal summarily with the offence, but referred it to the Assizes. Horner, who had shown signs of intense emotion during the proceedings, fainted away at the conclusion and was carried out of court.

“Hum! So much for the police-court,” said Holmes thoughtfully, tossing aside the paper. “The question for us now to solve is the sequence of events leading from a rifled jewel-case at one end to the crop of a goose in Tottenham Court Road at the other. You see, Watson, our little deductions have suddenly assumed a much more important and less innocent aspect. Here is the stone; the stone came from the goose, and the goose came from Mr. Henry Baker, the gentleman with the bad hat and all the other characteristics with which I have bored you. So now we must set ourselves very seriously to finding this gentleman and ascertaining what part he has played in this little mystery. To do this, we must try the simplest means first, and these lie undoubtedly in an advertisement in all the evening papers. If this fail, I shall have recourse to other methods.”

“What will you say?”

“Give me a pencil and that slip of paper. Now, then:

“Found at the corner of Goodge Street, a goose and a black felt hat. Mr. Henry Baker can have the same by applying at 6:30 this evening at 221B, Baker Street.

That is clear and concise.”

“Very. But will he see it?”

“Well, he is sure to keep an eye on the papers, since, to a poor man, the loss was a heavy one. He was clearly so scared by his mischance in breaking the window and by the approach of Peterson that he thought of nothing but flight, but since then he must have bitterly regretted the impulse which caused him to drop his bird. Then, again, the introduction of his name will cause him to see it, for everyone who knows him will direct his attention to it. Here you are, Peterson, run down to the advertising agency and have this put in the evening papers.”

“In which, sir?”

“Oh, in the Globe, Star, Pall Mall, St. James’s, Evening News Standard, Echo, and any others that occur to you.”

“Very well, sir. And this stone?”

“Ah, yes, I shall keep the stone. Thank you. And, I say, Peterson, just buy a goose on your way back and leave it here with me, for we must have one to give to this gentleman in place of the one which your family is now devouring.”
