After traveling on the Blue Train from Calais to Nice, Hercule Poirot is pressed into service to help solve the murder of heiress Ruth Kettering who is found savagely beaten in her compartment. She was the daughter of wealthy industrialist Rufus Van Alden and very much wanted a divorce. Both her husband and her lover were on the train but she had changed rooms with another passenger, Katherine Grey, so the question naturally arises as to whether she was the intended victim. Grey may also have had enemies as she had recently inherited a very large sum of money and greedy relatives had suddenly taken a interest in her. When an attempt is subsequently made on Grey's life, this appears to the case but Poirot methodically sifts through all of the clues to determine the motive and identify the killer.

His friend, solicitor Gilbert Entwhistle, asks Hercule Poirot to help solve a riddle and a murder. The riddle has to do with Richard Abernethie's will. It would seem that he changed his will immediately prior to his death, distributing all of his wealth equally among family members but excluding George Abernethie who, in all previous wills, had been the sole beneficiary. The two had supposedly argued recently, but Entwhistle suspects the new will may be a forgery. As for the murder, he would like Poirot to investigate the death of Cora Galaccio, who was violently beaten to death the day after Richard's funeral. She too had inherited from the suspect will, but are the two deaths and the will all part of a greater plot, or is there a simpler explanation? Written by garykmcd
