The Big Four
1924
In this early Poirot adventure, Agatha Christie trades her famous locked-room puzzles for something bolder: international conspiracy. When a dust-covered stranger staggers into Poirot's bedroom, collapses, and scribbles the number 4 over and over, the detective and Captain Hastings are thrust into a shadowy world of espionage and dangerous secrets. The Big Four is a ruthless criminal organization led by the formidable Li Chang Yen, a mastermind whose reach extends across continents. Poirot must navigate a web of spies, stolen secrets, and assassination attempts while maintaining his legendary methodical calm. The stakes are both personal and global: enemies threaten not just individuals, but the fragile peace between nations. This 1927 novel shows Christie stretching beyond the country-house mystery, offering readers a darker, more politically charged thriller that foreshadows the genre's evolution. Perfect for readers who want their Poirot with a side of geopolitical intrigue.

And you, too, mon ami - though that would not be such a national catastrophe." "Thank you," I said coldly.””
