Cody Jenkins is a detective on the Augusta police force. A veteran of the Korean War and a former Military Policeman, he has aspirations of one day working in a big city. On his own time, he collects available data on unsolved murders all over the nation for a ten year period. By applying the same data to all of the cases he narrows the list down to twelve cases that all appear to have been committed by the same man. They are scattered all over the nation and he searches for some method to validate his premise that all were committed by the same party. In the process he manages to establish the occupation of the suspect. When a murder using the same MO is committed in Augusta, he knows he is on the right track. He enlists the help of the FBI, who form a Task Force to look into the homicides. While the Masters Golf Tournament is being played, another murder is committed in the woods on the golf course. The FBI Director is incensed that a murder could have been committed while the suspect was under constant FBI surveillance. The winner of the golf tournament is a surprise, but the way the FBI brings the killer to justice is an even bigger surprise.
