his 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."

"Such a fact must tell against the theory that the man who breaks them
is influenced by any general hatred of Napoleon. Considering how many
hundreds of statues of the great Emperor must exist in London, it is
too much to suppose such a coincidence as that a promiscuous iconoclast
should chance to begin upon three specimens of the same bust."

"Well, I thought as you do," said Lestrade. "On the other hand, this
Morse Hudson is the purveyor of busts in that part of London, and these
three were the only ones which had been in his shop for years. So,
although, as you say, there are many hundreds of statues in London, it
is very probable that these three were the only ones in that district.
Therefore, a local fanatic would begin with them. What do you think, Dr.
Watson?"

"There are no limits to the possibilities of monomania," I answered.
"There is the condition which the mo
