21. Mr Ratchett had been stabbed twelve times, and, as usual, there was a limited field of suspects. In which episode did Poirot reveal that they all did it?
From Quiz All Will Be Revealed
Answer:
Murder on the Orient Express
In the fourth episode of series twelve, originally aired in 2010, Poirot found himself on board the Orient Express when it became stuck in a snowstorm, and the unsavoury American was discovered dead, stabbed to death in his sleeping compartment. Poirot needed to discover the murderer before the train was free to move, and escape would be possible. In one of Agatha Christie's most well-known surprise endings, Poirot revealed that Ratchett was actually a fugitive named Cassetti, who had kidnapped and killed young Daisy Armstrong despite the payment of a large ransom. All the other passengers had been deeply wounded by the event and/or its aftermath, and had come together to act as a twelve-person jury to execute judgment on the man who had been the cause of their suffering. As Poirot explained, only this could explain the maze of conflicting clues that he had found. Or it might have been some unknown enemy who had secretly boarded the train, committed the murder, then escaped through the snow.
