From the liner notes

You're in good company with Hercule Poirot (Peter Ustinov), Agatha Christie's impeccable Belgian sleuth who's always at his best at chic soirees where the hospitality is warm...and the corpses are cold. Match wits with the master in this full-course banquet of mystery involving a country-house game of murder turned real (Dead Man's Folly), a move star turned amateur detective (Murder in Three Acts), and a dinner part turned deadly (Thirteen at Dinner). Bon appetit!
