Forensic orthopedic surgeon Ham Marks just wants a peaceful day at the Split Rock Golf Club. The club computer, ARNI, matches him up with three strangers for his relaxing eighteen holes, but during the course of play, one of his fellow golfers falls into the lake. Soon after, the man, Marty Rasher, is declared dead, and Ham is shocked to be a suspect.
To exonerate himself, he needs the help of his brilliant wife and fellow medical specialist, Ruth. Despite their brainpower, their scientific minds are not enough to solve this case, so they call in assistance. First, they get in touch with their friend, Agent Carter of the FBI, and secondly, Dr. Water of the EPA.
Rasher's family isn't helping the investigation. No one knows who would have wanted him killed. Marks and his friends follow up on a load of dead ends before getting even close to the killer. Meanwhile, the good doctor stays under suspicion. He never planned to encounter murder on the golf course, but now, solving the case might save his life.
