Murder on the Orient Express - Agatha Christie

Heavy snow delayed the train shortly after midnight.

The Orient Express was packed with passengers, which is strange at this time of year. But the passengers were one short in the morning; One of them was found murdered in his cabin with twelve stab wounds on his body, and the cabin door was locked from the inside!

Tension rises and confusion reaches its climax, but Poirot surprises everyone; He does not offer one solution to this strange crime, but two solutions!
