Agatha is a 1979 thriller directed by Michael Apted and based on real events surrounding the mystery novelist Agatha Christie. It is 1926, and Agatha (Vanessa Redgrave) has enjoyed an immensely successful career as a crime writer, captivating her readers with her sharp eye for detail and her love of suspense. In her personal life, Agatha is not the bold and confident woman that her readers might expect. She is shy and thoughtful, and when her husband Archie (Timothy Dalton) announces that he has been having an affair, Agatha does not know how to respond. Unable to handle the devastation of a failed marriage and grant Archie a divorce, Agatha instead vanishes into the night. For 11 days, her disappearance captures the interest and concern of the nation, including her husband. It is up to American journalist Wally Stanton (Dustin Hoffman) to beat a skilled sleuth at her own game and foil her dangerous plans.
