This is a classic first published in 1934 some 82 years ago. It had been made into a movie of the same title. It is not too late to read and enjoy this murder mystery on a train named Orient Express.
The famous private detective Hercule Poirot who was also travelling on the same coach was asked to investigate this murder. There were twelve other passengers in the coach and anyone of these passengers and staff working on the train could be a suspect.
The case was made more interesting because the passengers were from different nationalities. The evidences gathered from the start pointed towards impossibilities to pinpoint the real murderer.
I had my suspicion as to the real murderer and it took a reading to the end to ascertain whether I was correct.
