Los asesinatos de Kingfisher Hill

Hercule Poirot travels in a luxurious coach to the exclusive Kingfisher Hill mansion: Richard Devonport has asked him for help to prove that his fiancee, Helen, is innocent of the murder of his brother, Frank, despite the fact that she herself has confessed to the crime. On the way, a young woman suffers a nervous breakdown and demands to get out: she claims that if she remains in her seat she will be killed. She arranges for a seat change and the rest of the trip is uneventful. However, Poirot has a bad feeling; His fears are confirmed when a body is discovered in the Devonport home with a note referring to the "seat he shouldn't have sat in".
