Retired detective Hercule Poirot travels with his valet aboard a luxury train upon which an American heiress is murdered. But who did it–a gang of thieves who made off with her rubies? Her estranged husband? The estranged husband’s spurned mistress? Or someone else? Poirot, with the unexpected help of a newly rich young Englishwoman, must figure it out and bring the guilty party to justice.
This was a fun read, and I was genuinely surprised at the reveal.
