Four ruthless masterminds. One brilliant detective. A race against time to stop a worldwide catastrophe.

In The Big Four, Agatha Christie thrusts Hercule Poirot into one of his most dangerous cases yet. When a man collapses at Poirot's door-muttering about "The Big Four"-the legendary Belgian detective is drawn into a sprawling conspiracy involving espionage, murder, and global domination.

This is no ordinary murder mystery. Poirot and his loyal companion Captain Hastings face a mysterious international syndicate led by four powerful criminals: a brilliant Chinese mastermind, a French woman with no moral code, a ruthless American millionaire, and a silent killer who never fails.

Can Poirot's meticulous reasoning unravel the tangled web of lies and betrayal before the Big Four succeed in their plot?
