At Chimneys, Prince Michael, presumed heir to the long-empty throne of Herzoslovakia, is killed the night of his arrival. Cade was at Chimneys that same evening, leaving footprints outdoors but not indoors. He boldly introduces himself to Superintendent Battle, explaining the story of the memoirs, and persuading Battle of his innocence in the murder. After seeing that the dead prince had posed as Mr Holmes, Cade pursues his own ideas in finding the murderer, while Battle leads the main investigation. The next heir to the throne, Nicholas, cousin to Michael, was raising money on his expectations in America. Cade checks out the governess, a recent addition to the household; he travels to France to speak with her prior employer.
