From Quiz The Big Four
Answer:
Two years
Captain Hastings has returned to London, after some time in the Argentine. His wife, 'Cinderella' is still at the ranch. Poirot is delighted to see him, but says he is on his way to Rio. Abe Ryland, the soap king, wants him to investigate some dodgy dealings in a company. Just as Poirot prepares to leave, a stranger enters the room. He is obviously not well. He tells Poirot of 'The Big Four'. A Chinaman, Li Chang Yen, is 'Number One'; he is the brains of the gang. 'Number Two' seems to be an American, while 'Number Three' is a woman, nationality French. Poirot and Hastings leave the man in the flat and leave for the train. But during the journey, Poirot says he was being got out of the way. When they return to the flat, they find the stranger dead. They telephone the police. A keeper from the asylum comes to see the dead man and says that the man escaped from the asylum the previous night. When their friend, Inspector Japp, comes, he identifies the stranger as Maylering, a Secret Service man. He disappeared five years ago, was last heard of in Russia. Maylering was gagged then poisoned with prussic acid. The clock in the room has stopped at four o' clock. But Poirot says the clock shouldn't have stopped, it has been tampered with. When Poirot telephones the asylum, he learns that there has been no escape. The asylum keeper, who came to see them, was 'Number Four'. Next time, 'Number Four' will look completely different. This is a challenge for Poirot - to defeat 'The Big Four'.
