"The first case reported was four days ago," said he. "It was at the shop of Morse Hudson, who has a place for the sale of pictures and statues in the Kennington Road. The assistant had left the front shop for an instant when he heard a crash, and hurrying in he found a plaster bust of Napoleon, which stood with several other works of art upon the counter, lying shivered into fragments. He rushed out into the road, but, although several passers-by declared that they had noticed a man run out of the shop, he could neither see anyone nor could he find any means of identifying the rascal. It seemed to be one of those senseless acts of Hooliganism which occur from time to time, and it was reported to the constable on the beat as such. The plaster cast was not worth more than a few shillings, and the whole affair appeared to be too childish for any particular investigation. "The second case, however, was more serious and also more singular. It occurred only last night. "In Kennington Road, and within a few hundred yards of Morse Hudson's shop, there lives a well-known medical practitioner, named Dr. Barnicot, who has one of the largest practices upon the south side of the Thames. His residence and principal consulting-room is at Kennington Road, but he has a branch surgery and dispensary at Lower Brixton Road, two miles away. This Dr. Barnicot is an enthusiastic admirer of Napoleon, and his house is full of books, pictures, and relics of the French Emperor. Some little time ago he purchased from Morse Hudson two duplicate plaster casts of the famous head of Napoleon by the French sculptor, Devine. One of these he placed in his hall in the house at Kennington Road, and the other on the mantelpiece of the surgery at Lower Brixton. Well, when Dr. Barnicot came down this morning he was astonished to find that his house had been burgled during the night, but that nothing had been taken save the plaster head from the hall. It had been carried out and had been dashed savagely against the garden wall, under which its splintered fragments were discovered." Holmes rubbed his hands. "This is certainly very novel," said he. "I thought it would please you. But I have not got to the end yet. Dr. Barnicot was due at his surgery at twelve o'clock, and you can imagine his amazement when, on arriving there, he found that the window had been opened in the night, and that the broken pieces of his second bust were strewn all over the room. It had been smashed to atoms where it stood. In neither case were there any signs which could give us a clue as to the criminal or lunatic who had done the mischief. Now, Mr. Holmes, you have got the facts." "They are singular, not to say grotesque," said Holmes. "May I ask whether the two busts smashed in Dr. Barnicot's rooms were the exact duplicates of the one which was destroyed in Morse Hudson's shop?" "They were taken from the same mould."
