During a murder hunt game at a country house, to which Hercule Poirot is invited as an "expert", a real murder occurs.

A murder hunt? What fun a game played at a gracious country manor, complete with baffling clues, a "dead" body and prizes! It's sure to be a jolly good time for all...until the dead body turns up dead. Peter Ustinov (Death on the Nile) encores as Belgian sleuth Hercule Poirot, pitting his little grey cells against a cunning killer in a lively adaptation of Agatha Christie's novel. Jean Stapleton (All in the Family) co-stars as Poirot's old friend, detective novelist Araidne Oliver, who joins him on a real murder hunt rife with suspects: a self-made millionaire, a trophy wife with rocks on her fingers and in her head, a bad-boy architect, a jealous spinster, a handsome stranger, a secretive gentlewoman and many more. Can you discover the murderer before Poirot does? Happy hunting!
