After the Funeral

Following the funeral of Richard Abernethie, his family assembles at Enderby Hall for the reading of the will by his lawyer, Mr Entwhistle. His wealth is to be divided up between his surviving family: his brother Timothy Abernethie and his wife Maud; his sister Cora Lansquenet; his nephew George Crossfield; his first niece Rosamund Shane, and her husband Michael; his second niece Susan Banks, and her husband Gregory; and Helen Abernethie, the wife of his late brother Leo.

Although Richard died of natural causes and his death was expected, Cora makes the seemingly chance but potently disruptive comment that he was murdered. The day after the funeral, she is found dead, having been violently murdered in her sleep. No motive is obvious in Inspector Morton's investigations - while Cora's life income reverts to the Abernethie estate, her property goes to Susan, while her companion Miss Gilchrist receives a number of the paintings she made. However, doubts soon arise about Richard's death in the wake of her murder. Seeking help, Entwhistle contacts his friend, Hercule Poirot, to resolve the matter. Poirot contacts his old friend Mr Goby to investigate the family.

Each family member had their own reason for wanting Richard's wealth, and thus become a suspect in the murder. On the day of the inquest, Susan visits Cora's home to clean up her possessions for auction. She learns from Gilchrist that her aunt always painted from life, and that she collected paintings from local sales in the hopes of finding a valuable piece. The day after Cora's funeral, art critic Alexander Guthrie arrives to look through Cora's recent purchases as previously scheduled but finds nothing of value there. That evening, Gilchrist is poisoned with a slice of arsenic-laced wedding cake sent in the post; she survives, having only eaten a small portion. Gathering to select items from Richard's estate before its sale, the family are joined by Poirot and Gilchrist. During discussions, Helen comments about believing there was something odd on the day of the funeral, Gilchrist makes a remark about one of the decorations in Enderby, while Susan recalls finding a painting in Cora's possession, which she believed had been copied from a picture postcard and not painted from life, Cora's usual style.

Early the next morning, Helen telephones Entwhistle to inform him what she had realised was odd during Richard's funeral, but is struck savagely on the head before she can say more. Helen suffers a concussion and is taken away for her safety. As Inspector Morton prepares to ask each family member about their movements on the day of Cora's murder, Poirot startles everyone by revealing to them that her murderer was Miss Gilchrist. She had recognised a Vermeer amongst Cora's recent purchases that her employer had not, and knew it was her chance to rebuild her beloved tea shop that she lost in the war. She painted over the Vermeer painting with a scene of a pier from a postcard, unaware it had been destroyed in the war. Afterwards, she put a sedative in Cora's tea so she would be asleep, while Gilchrist posed as her at the funeral. None of the family had seen Cora for more than two decades, which made her deception easier. After leaving the false suggestion that Richard had been murdered, Gilchrist killed Cora the following day so that police would believe it was connected to Richard's death. To divert suspicion from herself, Gilchrist faked the attempt on her life.

Gilchrist had to copy Cora's characteristic turn of her head but failed to realise one of these was wrong when she rehearsed it in front of a mirror. Helen was attacked because she eventually realised this. Furthermore, Poirot knew she had posed as Cora because she made a reference to a piece of decoration, which could only have been seen within Enderby Hall on the day of Richard's funeral. The Vermeer was hidden by Gilchrist so Guthrie did not find it during his scheduled visit. Her claim that Cora painted the pier scene from life was countered by Susan finding a pre-war postcard of the pier in the cottage, along with Entwhistle recollecting that he smelt oil when he visited Cora's home after her murder when he contacted Poirot for help. Poirot then reveals that two nuns visited Cora's cottage on the day of the funeral, and believed someone was inside.

Once accused, Gilchrist breaks down into a flood of complaints about the hardships of her life but quietly goes with the police. During legal proceedings before her trial, she eventually becomes insane, planning one tea shop after another, though Poirot and Entwhistle have no doubt she was in full possession of her faculties during her crime.
