“An extraordinary case, Mr Sholmes,” said the inspector. “Mr Skinnem, the managing director of Messrs. Skull & Krossbones, the shipowners, was found dead in his private office. There was no sign of violence about the body, and death had apparently been instantaneous. The medical evidence is the Mr Skinnem had been the victim of a sudden shock – how administered, it is for the police to discover.”
