Agatha and the Truth of Murder

Agatha and the Truth of Murder is a 2018 British alternative history drama film about crime writer Agatha Christie becoming embroiled in a real-life murder case during her 11-day disappearance in 1926. Written by Tom Dalton, it depicts Christie investigating the murder of Florence Nightingale's goddaughter, Florence Nightingale Shore, which is based on real people and events, and how her involvement in this case influenced her subsequent writing.

The film premiered on Channel 5 in the United Kingdom on 23 December 2018; becoming the network's most popular programme of the Christmas period and the second-highest rated fictional programme of the year.

Plot
In 1926, Agatha Christie finds herself in a difficult place when her writing is thwarted by predictable plot lines and her unfaithful husband pushes her for a divorce she does not want. As she searches for a way to revive her novel development, she is approached by Mabel Rogers, who is seeking help in solving the murder in 1920 of her partner, Florence Nightingale Shore, who had been bludgeoned to death on a train. Though initially reluctant to undertake a private investigation, Christie goes undercover while the nation searches for her whereabouts.

Calling herself Mary Westmacott (an early Christie pseudonym), she gathers all the suspects in the attack in a country house under the pretext of determining their share of a large inheritance from a fictitious American businessman, with herself as the representative of a law firm and Mabel acting as housekeeper and cook. The suspects include Daphne Miller, a young woman whose nursing career Florence could have ruined if she had lived; Randolph, Florence's cousin who inherited her money; Zaki Hanachi, a French soldier of Algerian ancestry whom she helped recover after the war and who may have been asking her for money; Travis Pickford, a boxer and black marketer who was interviewed by the police; and Mrs. Pamela Rose, the woman Florence was travelling to see. Daphne is accompanied by her abusive father Wade, and Mrs. Rose by her son Franklin, a former chaplain. Mabel is able to search the guests' bags, and finds that Wade Miller may have a pistol with him. To try and force a reaction from the others, Christie announces after the first interview that Daphne will get the biggest share of the inheritance.

Events take a turn when Daphne's father is shot dead. Detective Inspector Dicks arrives with a single constable, complaining that he is shorthanded because of the hunt for Agatha Christie, and that because of this he must conduct the investigation at the house instead of the police station. It is quickly discovered that they have been gathered together under false pretenses, and Christie changes her story to suit. Mabel is found in possession of the murder weapon and arrested. Dicks reveals to Christie that he knows who she is. He also knows that Daphne shot her father. Christie, having found a vital detail in Florence's diary, tells him she knows who attacked Florence and asks for his help. They spring a trap to get Pamela Rose and her son to admit their involvement. Even after Dicks and others overhear the conversation, the evidence is too thin to convict them, despite there being proof that they wrote a note blackmailing Daphne into planting the gun in Mabel's room. Instead, the others conspire to frame Florence's killers for the murder of Daphne's father.

Inspector Dicks helps Christie set up the cover story for her disappearance and inadvertently helps her get the idea for a new book. She is shown later completing a manuscript which appears to be Death on the Nile.
