Hercule Poirot observed his fellow passengers on the Orient Express: a Russian princess, an English colonel, an American with a strange glint in his eye and many more. He was looking forward to a peaceful journey. But is was not to be. Just after midnight, a snowdrift stops the Orient Express in its tracks. The luxurious train is surprisingly full for the time of the year, but by the morning it is one passenger fewer. An American tycoon lies dead in his compartment, stabbed a dozen times, his door locked from the inside. Isolated and with a killer in their midst, detective Hercule Poirot must identify the murderer - in case he or she decides to strike again.
