The "Curtain: Poirot's Last Case" by Dame Agatha Christie was actually written during World War II but knowing it would he the last book involving the beloved Belgian detective, Ms. Christie had it sealed in a vault along with the novel "Sleeping Murder" (the last "Miss Marple" novel) with plans to have them published at or near the end of her life when she would no longer be able to write. Four months after "Curtain" was published Dame Agatha Christie died but since the novel was generally well-received critically, she gave permission for "Sleeping Murder" to be published the following year in 1976 which she would never see.
Although this is the last Hercule Poirot story published by Agatha Christie, it was actually the first from the final series to be filmed, as requested by David Suchet, the actor of Hercule Poirot, himself.
Alice Orr-Ewing, who plays Arthur Hastings' daughter Judith, was born in 1989, the same year that the series was first broadcast, and all the main characters, including her father, were first introduced.
