内容简介：
Former university president, Parker Williams, opens a fly shop in West Yellowstone, Montana. While providing fly-fishing guide services on the Firehole River in Yellowstone National Park to a group of university presidents, he discovers the body of one of the presidents. An autopsy reveals the dead president was murdered. Considered a prime suspect, Parker sets out to clear his name and find the killer. Aided by a female Assistant Superintendent of Yellowstone National Park and often one step ahead of the FBI agent in charge of the investigation and the local Sheriffs department officer assigned to the case, the murder seems to be a perfect crime until Parker is led to an unexpected and bizarre conclusion.
