When the fabled Blue Train, the luxury overnight passenger express to the Riviera, arrives at Nice, a guard attempts to awaken Ruth Kettering from her slumbers. But the wealthy American socialite will never wake again, for a brutal blow has killed her, disfiguring her almost beyond recognition. What is more, her famously valuable rubies are missing. The prime suspect is Ruth's estranged husband, Derek. Yet Hercule Poirot is not convinced, and so he stages an eerie reenactment of the journey--with all of the suspected murderers aboard. A VINTAGE CLASSIC MYSTERY
