Sidelined by his war injuries in 1916, Captain Hastings travels to his friend’s estate at Styles Court to recover from his wounds. As the summer heats up, a tragic murder occurs, and Hastings calls upon the services of his old acquaintance Hercule Poirot. With seemingly unrelated clues - a scrap of a burned will, a false beard, and an empty packet of bromide - the brilliant detective launches his first investigation on English soil and forges an enduring friendship.

Enjoy the first novels that brought the world two of Agatha Christies’ most enduring detectives: Miss Marple and Hercule Poirot. The Murder at the Vicarage is the first Miss Marple mystery, one which tests all her powers of observation and deduction. In The Mysterious Affair at Styles, Captain Arthur Hastings, invalided in the Great War, is recuperating as a guest of John Cavendish at Styles Court, the "country-place" of John's autocratic old aunt, Emily Inglethorpe.

Mr. Shaitana is famous as a flamboyant party host. Nevertheless, he is a man of whom everybody is a little afraid. So when he boasts to Hercule Poirot that he considers murder an art form, the detective has some reservations about accepting a party invitation to view Shaitana's "private collection". Indeed, what begins as an absorbing evening of bridge is to turn into a more dangerous game altogether.

Maisie Dobbs got her start as a maid in an aristocratic London household when she was thirteen. Her employer, suffragette Lady Rowan Compton, soon became her patron, taking the remarkably bright youngster under her wing.

Ten years after the Armistice, in the spring of 1929, Maisie sets out on her own as a private investigator, one who has learned that coincidences are meaningful, and truth elusive.
