Murder on the Orient Express, Level 4

***While en route from Syria to Paris, in the middle of a freezing winter's night, the Orient Express is stopped dead in its tracks by a snowdrift.*** Passengers awake to find the train still stranded and to discover that a wealthy American has been brutally stabbed to death in his private compartment. Incredibly, that compartment is locked from the inside. With no escape into the wintery landscape the killer must still be on board. ***Fortunately, the brilliant Belgian inspector Hercule Poirot is also on board, having booked the last available berth.*** ***Murder on the Orient Express is one of Agatha Christie’s most famous novels***, owing no doubt to a combination of its romantic setting and the ingeniousness of its plot; its non-exploitative reference to the sensational kidnapping and murder of the infant son of Charles and Anne Morrow Lindbergh only two years prior; and a popular ***1974 film adaptation, starring Albert Finney as Poirot - one of the few cinematic versions of a Christie work that met with the approval, however mild, of the author herself.***
