A young woman witnesses the murder of a family by a killer and undertakes to capture him. She is Chyna Sheperd, a California psychology student staying at a friend's house when Edgler Vess, a "homicidal adventurer," arrives for a bit of fun. Chyna grabs a butcher's knife and hides in Vess' motor home where she finds more bodies, sees Vess kill again en route, is forced to flee, follows him in a stolen car, slips inside his house to find a girl prisoner--and becomes prisoner herself. By the author of Dark Rivers of the Heart.
