Zavjesa: Poirotov posljednji slučaj

The novel not only returns the plot to the first novel The Mysterious Affair in Styles, but reunites Poirot and Hastings, who have not been together for decades.

Hastings comes to Styles St. Mary to visit her daughter and Poirot. At the entrance he meets Mr. and Mrs. Luttrell. He went to Poirot's room and along the way met Stephen Norton and Sir William Boyd Carrington. When he came to Poirot, he told him that it was bad and that a murder was about to happen, and that the murderer was the mysterious "X". Poirot knows who he is, but doesn't want to tell Hastings.

Hastings investigated. The first accident happened. Mrs. Luttrell was shot in the arm. After a few days, a murder happened. Barbara Franklin was killed, but the police concluded that it was a suicide. In the end, Norton was also killed, and Poirot died the next day after that event. He left a letter for Hastings explaining everything.
