One of the most influential mystery writers of all time, Agatha Christie is represented here by eight of her earliest and most influential novels and story collections. Meet Hercule Poirot for the first time in The Mysterious Affair at Styles and follow him through The Murder on the Links, the story collection Poirot Investigates, and the genre-redefining The Murder of Roger Ackroyd, whose twist ending changed detective fiction forever. Alongside Poirot, adventurous newlyweds Tommy and Tuppence Beresford make their debut in The Secret Adversary, hunting Bolshevik conspirators through 1920s London, while The Man in the Brown Suit and The Secret of Chimneys deliver fast-paced Christie thrillers packed with disguise, blackmail, and stolen jewels. This Chronicle Vault edition presents all eight novels and story collections complete and unabridged, in a clean, fully reflowable format for all e-readers.
