The Main Line is Murder (Ginger Barnes Main Line Mysteries) by Donna Huston Murray
When her husband becomes head of a school on Philadelphia’s tony Main Line, Ginger Barnes learns that small private schools need volunteers like the national debt needs taxes. She also learns that murder on the campus can kill the school’s reputation in a heartbeat. Gin’s Mop Squad job allows her to investigate without arousing suspicion, but can she expose the murderer in time to save the school–and her family’s new home–without exposing herself? If she succeeds, will her good deed go unpunished?
