The Big Four

Hercule Poirot's peaceful evening takes a dramatic turn when a mysterious, dying man collapses in his apartment, uttering only Poirot's name, address, and repeatedly scrawling the number '4'. This cryptic incident quickly unfolds into Poirot's most perilous challenge yet, as his friend Captain Hastings jokingly dubs it 'The Mystery of the Big Four'. The dying man reveals he was targeted by an enigmatic international criminal cartel known as 'The Big Four', a sinister organization comprising four masterminds: Li Chang Yen, a Chinese political genius; an unnamed American millionaire; a cunning Frenchwoman; and the brutal, elusive 'Destroyer'. Driven by a sense of justice and the sheer audacity of his opponents, Poirot, alongside Hastings and Chief Inspector Japp, embarks on a globe-trotting chase to dismantle this powerful syndicate. From the bustling streets of London to the serene Swiss Alps, they navigate a web of espionage, assassinations, and psychological warfare, pushing Poirot's intellect to its limits against a foe unlike any he's faced before.
