Inspector Dicks helps Christie set up the cover story for her disappearance and inadvertently helps her get the idea for a new book. Instead, the others conspire to frame Florence's killers for the murder of Daphne's father. 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. They spring a trap to get the real killers to admit their involvement. Christie, having found a vital detail in Florence's diary, tells him she knows who attacked Florence, and asks for his help. He also knows that Daphne shot her father, based on an injury to her hand from the recoil of the automatic pistol. Dicks reveals to "Mary" that he knows that she is Agatha Christie. Mabel is found in possession of the murder weapon and arrested. It is quickly discovered that they have been gathered together under false pretenses, and "Mary" changes her story to suit. 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. To try and force a reaction from the others, "Mary" announces after the first interview that Daphne will get the biggest share of the inheritance.Įvents take a harrowing turn when Daphne's father is shot dead. Mabel is able to search the guests' bags, and finds that Wade Miller may have a pistol with him. Rose by her son Franklin, a former chaplain.

Daphne is accompanied by her abusive father Wade, and Mrs.

Pamela Rose, the woman Florence was travelling to see.

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 who 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. She soon finds herself taken to a new story with real characters and tangible danger.Ĭalling 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. Though initially reluctant to facilitate a private investigation, Christie goes undercover while the nation searches for her whereabouts. As she searches for an alternative creative route to revive her novel development, she is approached by a woman, Mabel Rogers, seeking help in solving the murder of her partner, Florence Nightingale Shore, who had been bludgeoned on a train. 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. The murder of Florence Nightingale Shore, and the character of Mabel Rogers, are based on real people and events. The plot uses elements of classic detective novels, and also contains references to Christie's novels, such as The Man in the Brown Suit, the title of which appears as a headline in a newspaper clipping.
