The Big Four

A secret criminal organization. Four shadowy masterminds. One detective who dares to challenge them. The Big Four is one of Agatha Christie's most action-packed novels, starring the brilliant Belgian detective Hercule Poirot.

When Poirot stumbles upon the existence of a global network of criminals—known only as The Big Four—he faces one of the greatest challenges of his career. Each adversary is a genius in their own right: a financial tycoon, a brilliant scientist, a ruthless assassin, and a mysterious fourth figure whose identity shocks the world.

Unlike the traditional country house murders Christie is famous for, this novel plunges Poirot into an international conspiracy full of espionage, danger, and suspense. With Captain Hastings by his side, Poirot must untangle a web of plots, betrayals, and near-death escapes in his battle against a seemingly invincible enemy.

Celebrated for its fast pace, dramatic twists, and larger-than-life stakes, The Big Four offers a unique and thrilling chapter in the Poirot canon that showcases Christie's versatility as a writer.
