Arthur Hastings is on leave recuperating during the First World War. When on convalescence he meets an old friend, John Cavendish, who invites Hastings to stay with him and his family at Styles. While he’s there, John’s stepmother, Emily Inglethorp, is murdered, and Hastings persuades John to allow his friend, the Belgian detective Hercule Poirot, to investigate.
This is the first of Agatha Christie’s Poirot mysteries and I found it very enjoyable. Some of the language is is very dated, but the mystery itself is intriguing and Poirot is a fantastic character.
