Elinor Carlisle is a happy girl - She is engaged to the man she loves, and she has no money troubles, at least for the present. She is at a gentle point in life. But she is another person altogether underneath her calm, cool and collected facade. She is a passionate person, deeply in love with her fiance Roddy and devoted to him - but she can't show that side of herself lest she scare him off. She manages to keep it under control. But then Mary Gerrard comes into the story - first within an anonymous letter warning Elinor against someone- someone trying to steal her inheritance from her old, sick aunt through kindness. And Elinor thinks it's Mary.
When Elinor and Roddy go to visit her sick aunt, Roddy falls in love with Mary at first sight and Elinor now has a reason to passionately hate the beautiful, kind young girl. Even enough to kill her...
So when Mary Gerrard is found poisoned, Elinor Carlisle is the likely suspect. And perhaps even Hercule Poirot won't be able to declare her innocent.
