It stars Helen Hayes as Miss Marple and Bette Davis as her old American friend from their days touring Italy as young ladies. Miss Marple is called on to investigate possible causes of her friend's deteriorating health. However, as Miss Marple keeps her friend company, her attention is soon diverted as she stumbles over a dead body. A murderer is at large in a house of suspects (Brocket Hall), and a race against time begins. The film marks Helen Hayes' last appearance as Miss Marple; indeed, it was her last film role. The film also stars John Mills, Tim Roth, Leo McKern and Dorothy Tutin.
The novel has been dramatised three more times: in 1980’s feature film The Mirror Crack'd with Angela Lansbury as Miss Marple and a cast including Rock Hudson and Elizabeth Taylor under director Guy Hamilton; with Joan Hickson as Miss Marple for the BBC’s 1980s series; and with Julia McKenzie for ITN’s Agatha Christie's Marple. The latter two used the novel's original title.
