S1·E7 The Six Napoleons

Inspector Lestrade of Scotland Yard brings Holmes a mysterious 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.
