Which author wrote 'Death on the Nile'?

Agatha Christie wrote the mystery novel Death on the Nile.

First published in 1937, the book features Hercule Poirot investigating a killing during a journey along Egypt’s Nile River. Its enclosed setting, wealthy passengers, hidden relationships, and carefully planted clues make it a classic example of Christie’s puzzle-driven detective fiction.

The novel was published in the United Kingdom by the Collins Crime Club on 1 November 1937, with an American edition following in 1938. It belongs to Christie’s Poirot series and was published after Dumb Witness and before Appointment with Death.

Readers sometimes confuse the novel with Christie’s earlier short story also called “Death on the Nile.” That story is unrelated and features Parker Pyne rather than Poirot. The novel has since been adapted for stage, television, film, radio, and video games, but the original author remains Agatha Christie.
