Lexie's best friend, Rosie, asks her to lead the Golden Age of Mystery book club she has created. The first meeting, a discussion of Agatha Christie novels, is held in Rosie and Hal’s mansion in the upscale village of Old Cadfield. Lexie muses that she could have lived the elegant life--if she hadn’t broken up with Hal when they were in college. If only she hadn't found him boring.
Before the meeting, Lexie overhears Sylvia, an old friend of hers, arguing with a neighbor. “Write that book if you dare, but you won’t live to see it in print!” Gerda tells Sylvia. An hour later, Sylvia is dead.
Lexie agrees to house sit Sylvia’s Old Cadfield home for the duration of the summer. While she appreciates her lovely surroundings and enjoys having a private pool at her disposal, she doesn’t feel comfortable with the Old Cadfield crowd. As she investigates Sylvia’s death and gets to know the book club members better, Lexie learns that money doesn’t necessarily make for happiness. Each member harbors a secret. The murderer strikes again, and Lexie begins to feel she’s living an Old Cadfield version of Agatha Christie’s Ten Little Indians.
Lexie is drawn to two very appealing, sexy men: the renown architect who built Sylvia’s home and the homicide detective in charge of the murder investigation. Will she make the "right" choice this time?
And then an "accident" occurs, and Lexie barely escapes with her life. The murderer is losing control. Lexie employs Poirot’s power of deduction and Miss Marple’s cleverness to find the murderer before he/she kills again.
