Body Wave

In Nancy J. Cohen's fourth bubbly Bad Hair Day mystery, Body Wave, Florida hairdresser Marla Shore agrees to help her snake of an ex-husband, Stan Kaufman, who's been arrested for the murder of his third wife, Kimberly, find the real killer. Cheered on by her heartthrob, homicide detective Dalton Vail, Marla goes undercover as a nurse and discovers that plenty of people, from Stan's jilted second wife to members of the victim's own well-to-do family, had reason to want Kimberly dead.
