A curious group of passengers is assembled on the Istanbul–Calais coach of the Simplon Orient Express. They include a Russian princess, an Italian salesman, an English colonel … and Hercule Poirot. The morning after the train is stopped dead by a deep snowdrift, American millionaire Mr Ratchett is found stabbed to death, his compartment bolted on the inside. It is clear that the murderer must be one of his fellow passengers and must therefore still be on the train. One of Christie’s most famous novels, Murder on the Orient Express boasts a truly audacious solution and has kept readers rapt since it was first published in 1934.
