Agatha and the Truth of Murder

Written by Tom Dalton, this British alternative history drama explores how crime writer Agatha Christie became embroiled in a real-life murder case during her 11-day disappearance in 1926. The film depicts Christie investigating the murder of Florence Nightingale's goddaughter and how her involvement in the case influenced her subsequent writing. The plot uses elements of classic detective novels and contains references to Christie's books, such as The Man in the Brown Suit, which appeared as a headline in a newspaper clipping. The murder of Florence Nightingale Shore and the character of Mabel Rogers are based on real people and events. The film premiered on Channel 5 in the United Kingdom in December 2018, becoming the network's most popular holiday program and the second-highest rated fictional program of the year.
