Los Angeles County Sheriff’s Detective Stilwell has been “exiled” to a low-key post policing rustic Catalina Island, after department politics drove him off a homicide desk on the mainland. But while following up the usual drunk-and-disorderlies and petty thefts that come with his new territory, Detective Stilwell gets a report of a body found weighed down at the bottom of the harbor --- a Jane Doe identifiable at first only by a streak of purple dye in her hair. At the same time, a report of poaching on a protected reserve turns into a case fraught with violence and danger as Stilwell digs into the shady past of an island bigwig. Crossing all lines of protocol and jurisdiction, Stilwell doggedly works both cases.
