Many avid Sandford readers have enjoyed his 20 previous Lucas Davenport "Prey" novel series. This book is the second in a spin-off series that stars Virgil Flowers. Virgil is a lover and a loner. He has long blond locks, wears cowboy boots and controversial T-shirts, and drives a pickup truck that usually is pulling a fishing boat. He is the author of outdoor adventure articles that get published regularly in an assortment of magazines. Virgil is a special investigator for the Minnesota Bureau of Criminal Apprehension (BCA). Virgil's boss, Davenport, calls on him to solve the most difficult cases. This book is about unpunished Vietnam War crimes and a professional hit team that has come to America for long-awaited payback. Virgil Flowers is a unique character. He is intelligent, resourceful, and quite the ladies-man. He does a lot of his deep thinking while driving or fishin' on a lake or river. Even though I was able to figure out the ending about 70-pages in, I was not disappointed in the journey.
