 Well, considering how many examples of Napoleon's busts there must be, no amount of monomania would explain why such a promiscuous iconoclast should chance to begin on three examples by the same sculptor. As I take it, Lestrade, these three are all copies of the same original and all bought at this man Hudson's shop. Every one, Mr. Holmes. Identical. Why, then, the fellow may have an obsession against the sculptor. Possibly.
