Assassinat a l'Orient Express

In an isolated place in the former Yugoslavia, in the morning, a heavy snowstorm cuts off the road on the Orient Express. One of his passengers, Samuel Edward Ratchett, has been killed while sleeping and there appears to be no clear cell phone. Detective Hercule Poirot is faced with one of the most puzzling mysteries of his career; no one got on or off the train, as it was trapped by the snowstorm, so all the passengers on the train became suspicious of the death. One victim, twelve suspects and a privileged mind searching for the truth.
