"What I intend to say to you will come as a shock ..." With these words, Lady Athelinda Playford -- one of the world's most beloved children's authors -- springs a surprise on the lawyer entrusted with her will. As guests arrive for a party at her Irish mansion, Lady Playford has decided to cut off her two children without a penny ... and leave her vast fortune to someone else: an invalid who has only weeks to live. Among Lady Playford's visitors are two strangers: the famous Belgian detective Hercule Poirot, and Inspector Edward Catchpool of Scotland Yard. Neither knows why he has been invited -- until Poirot begins to wonder if Lady Playford expects a murder. But why does she seem so determined to provoke a killer? And why -- when the crime is committed despite Poirot's best efforts to stop it -- does the identity of the victim make no sense at all?

"Hercule Poirot is traveling by luxury passenger coach from London to the exclusive Kingfisher Hill estate. Richard Devonport has summoned the renowned detective to prove that his fiancée, Helen, is innocent of the murder of his brother, Frank. Poirot will have only days to investigate before Helen is hanged, but there is one strange condition attached: he must conceal his true reason for being there from the rest of the Devonport family. The coach is forced to stop when a distressed woman demands to get off, insisting that if she stays in her seat, she will be murdered. Although the rest of the journey passes without anyone being harmed, Poirot's curiosity is aroused, and his fears are later confirmed when a body is discovered with a macabre note attached... Could this new murder and the peculiar incident on the coach be clues to solving the mystery of who killed Frank Devonport? And if Helen is innocent, can Poirot find the true culprit in time to save her from the gallows?"--

"It's December 19, 1931. Hercule Poirot and Inspector Edward Catchpool are looking forward to a much-needed, restful Christmas holiday, when they are called upon to investigate the murder of a man in a Norfolk hospital ward. Cynthia Catchpool, Edward's mother, insists that Poirot stay with her in a crumbling mansion by the coast, so that they can all be together for the festive period while he solves the case. As Poirot digs into the mystery, he discovers that the murdered man was a retired post office master, and by all accounts very well-liked. The local constabulary's investigation failed to uncover how someone could have entered a hospital room and killed him under the noses of the staff. Cynthia's friend Arnold is soon to be admitted to that same hospital, and his wife is convinced he will be the killer's next victim, though she refuses to explain why. With no obvious motive or suspect, Poirot has less than a week to solve the crime and prevent more murders, if he is to escape from this nightmare scenario and get home in time for Christmas. Meanwhile, someone else also has ideas about what ought to happen to Hercule Poirot"--
