First, "Why Didn't They Ask Evans?" (1980) are the mysterious last words of a murdered man in 1930s England, and, along with a photo of an unknown girl found on the victim, they're the only clues that would-be sleuth Bobby Jones and friend Lady Frankie Derwent have as they attempt to solve the mystery behind the death. Stylish version of Agatha Christie's whodunit stars James Warwick, Francesca Annis, Eric Porter, and John Gielgud. Next, two men employed by the British government are found murdered in 1920s England, and society girl/flapper/amateur detective Lady Eileen Brent is soon hot on the killer's trail, uncovering a plot involving international espionage. The crackling Christie mystery "Seven Dials Mystery" (1982) stars Cheryl Campbell, Harry Andrews, Warwick, and Gielgud. Then, a Christie thriller from 1945 gets a modern-day adaptation, as "Sparkling Cyanide" (2003) takes the life of a soccer manager's wife. Whodunit? That will have to be answered by the two MI5 agents assigned to investigate! Pauline Collins, Oliver Ford Davies, and Jonathan Firth star. 6 2/3 hrs. total on three discs.
