In this mystery, Peter Ustinov reprises the role of Hercule Poirot, the fussy and flower-tending detective from Belgium created by Agatha Christie. In 1937, Mrs. Emily Boynton (Piper Laurie) is on an archeological dig in Palestine; she inherited the wealth of her recently deceased husband and feels little inclination to share it with her relatives. When she turns up murdered, there are plenty of logical suspects among the people who hated Emily, so which one did the deed? It's up to Poirot to find out. The supporting cast includes Lauren Bacall, John Gielgud, and Carrie Fisher; the film was Ustinov's sixth go-round as Poirot.
