Curtain: Poirot's Last Case is a work of detective fiction by British writer Agatha Christie, first published in the UK by the Collins Crime Club in September 1975 and in the US by Dodd, Mead and Company later in the same year, selling for $7.95.
The novel features Hercule Poirot and Arthur Hastings in their final appearances in Christie's works. It is a country house novel, with all the characters and the murder set in one house. Not only does the novel return the characters to the setting of her first, The Mysterious Affair at Styles, but it reunites Poirot and Hastings, who last appeared together in Dumb Witness in 1937. The fictional detective dies at the end. It was adapted for television in 2013.
