The only clue that could lead to the arrest of a homicidal killer is a golf ball button, torn from the jacket the killer was wearing, and found next to the horrifyingly mutilated body of a young hooker. There are four owners of jackets with golf ball buttons living in the city. When Detective Tom Lepski of the Paradise City Police checks out these jackets, suspicion falls on Ken Brandon, an insurance agent. But just when Lepski is sure he has his man, two more horrifying killings occur, and he is faced with the trickiest case he's ever had to solve.
