The Mysterious Affair At Styles and The Secret Adversary (Illustrated)

Styles was Christie's first published novel, introducing Hercule Poirot, Inspector (later, Chief Inspector) Japp, and Arthur Hastings. Poirot, a Belgian refugee of the Great War, is settling in England near the home of Emily Cavendish, who helped him to his new life. His friend Hastings arrives as a guest at her home. When the woman is killed, Poirot uses his detective skills to solve the mystery. This is also the setting of Curtain, Poirot's last case. In the Prologue, a man aboard the RMS Lusitania on 7 May 1915 quietly gives important papers to a young American woman, as she is more likely to survive the sinking ship. In 1919 London, demobilised soldier Tommy Beresford meets war volunteer Prudence "Tuppence" Cowley, both out of work and money. They form the "The Young Adventurers, Ltd", planning to hire themselves out with "[n]o unreasonable offer refused."
