The Big Four

Agatha Christie takes Hercule Poirot out of the drawing room and into the world of international intrigue in this 1927 thriller. When a dying stranger stumbles into Poirot’s flat and gasps out warnings about a secret cartel, the detective and his loyal friend Hastings set out to expose the Big Four, a quartet of masterminds bent on world domination. Assembled from a run of linked short stories, the book unfolds as a chase across a series of episodes, full of disguises, near escapes, and a shadowy adversary known only as Number Four, the destroyer. Lighter and more far-fetched than Christie’s classic puzzles, it shows her trying her hand at the espionage adventure. Free to read here in PDF and EPUB.
