The Big Four

Agatha Christie

1924

British Literature, Novels

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.

“He laughs best who laughs at the end.””

— Agatha Christie

“He dragged me back - just in time. A tree had crashed down on to the side walk, just missing us. Poirot stared at it, pale and upset. "It was a near thing that! But clumsy, all the same - for I had no suspicion - at least hardly any suspicion. Yes, but for my quick eyes, the eyes of a cat, Hercule Poirot might now be crushed out of existence - a terrible calamity for the world. And you, too, mon ami - though that would not be such a national catastrophe." "Thank you," I said coldly.””

— Agatha Christie

“You surprise me, Hastings. Do you not know that all celebrated detectives have brothers who would be even more celebrated than they are were it not for constitutional indolence?””

— Agatha Christie

“Hercule Poirot's methods are his own. Order and method, and 'the little gray cells'.””

— Agatha Christie

“If one man does not make a move, the other must, and by permitting the adversary to make the attack one learns something about him.””

— Agatha Christie

“Meanwhile we have learnt something, and to know is to be prepared.””

— Agatha Christie

“You must remember, too," he added, "that we deal with no ordinary criminal, but with the second greatest brain in the world." I forbore to pander to his conceit by asking the obvious question.””

— Agatha Christie

“Poirot was standing in the larder in a dramtic attitude. In his hand he was brandishing a leg of mutton.'My dear Poirot! What is the matter? have you gone mad?''Regard i pray you this mutton! But regard it closely!””

— Agatha Christie

“Very difficult, mon ami. But as you know well, difficulties rejoice the heart of Hercule Poirot.””

— Agatha Christie
