Peter Ustinov stars once more as Hercule Poirot, Agatha Christie's insufferably brilliant Belgian detective. Unlike many of Ustinov's earlier Poirot vehicles, which were set in the 1930s, the made-for-TV Dead Man's Folly takes place in contemporary England. Jean Stapleton costars as an American mystery novelist who organizes a "murder hunt" at a sprawling English manor. It isn't long before several of the guests are also sprawling--on the ground, stone cold dead. American-born British stage star Constance Cummings makes a rare TV appearance as a mysterious noblewoman. Dead Man's Folly was lensed on location at West Wycombe Park in Buckinhamshire.
