Sir Arthur Ignatius Conan Doyle was a Scottish writer and physician, most noted for his fictional stories about the detective Sherlock Holmes, which are generally considered milestones in the field of crime fiction. He was a prolific writer whose other works include fantasy and science fiction stories, plays, romances, poetry, non-fiction and historical novels. In the story "The Adventure of the Six Napoleons" inspector Lestrade of Scotland Yard brings Holmes a seemingly trivial problem about a man who shatters plaster busts of Napoleon. One was shattered in Morse Hudson’s shop, and two others, sold by Hudson to a Dr. Barnicot, were smashed after the doctor’s house and branch office had been burgled. Nothing else was taken. In the former case, the bust was taken outside before being broken. Holmes knows that Lestrade’s theory about a Napoleon-hating lunatic must be wrong. The busts in question all came from the same mould. Why is he breaking them?
