The theme of wild and unusual sex practices runs throughout this book, but the descriptions never reach the level of pornography. Lindy Sutton is co-owner of a food catering company with only two employees and serves as the clown for parties. Her Aunt Pip is suffering from dementia and is currently housed in the Laughing Pines retirement home. Pip has regular flashbacks to France in World War II, occasionally launching "grenades" against the invading Nazis. The bombs she throws are often constructed of food and the "Germans" are any people that happen to be in the vicinity, an act that frustrates the people running the home. The managers are threatening to cancel the care contract over Pip's behavior, increasing the stress in Lindy's life, a problem compounded by the long time since Lindy has had sex.
After a birthday party for octogenarian women that ends up in a wild sex club, Margaret, the resident social worker at Laughing Pines is found dead of an apparent drug overdose. Those that knew Margaret refuse to believe that she was a taker of drugs and Lindy leads the amateur group that searches for the killer of Margaret. The lead detective on the case is a male hottie named Grogan that causes an immediate increase in Lindy's dormant sexual desire. She realizes that although she is fifty, her desire is still very strong.
Lindy is aided by her best friend Patty in their adventures in searching for the truth. Vowing to let nothing stand in the way, Lindy and Patty return to the sex club and investigate and attend a swinging sex party where you can swing both ways with any willing partner you can find.
The unconventional nature of the murder mystery, combined with the aspects that are an old-fashioned budding romance, combine to make this an entertaining story. There are some amusing scenes, the images that go through your mind when Lindy turns out to be more prudish than the octogenarians in their trip to the club are worthy of a short film. Properly done, it would be hysterical.
