Hazel Rose never dreamed that the murder mystery book group she and her friend Carlene started would stage a real murder. Nevertheless, the normally composed Carlene is unusually angry and rattled one night during a book group discussion and dies after drinking cyanide-spiked tea. Despite a suicide note, Hazel is skeptical; Carlene never seemed suicidal. Incidentally, Carlene was married to Hazel's ex-husband, and Hazel has always suspected there might be something more to her past than she let on. Hazel begins a search for the truth that produces no shortage of motives, as she unearths the past that Carlene took great pains to hide. And most of those motives belong to the members of her very own book group...
