Dark of the Moon and most recently, Heat Lightning, concern, as Prey readers all know him, "that fuckin' Flowers." Virgil Flowers, who likes punk rock band T-shirts, wears his blond hair long, and is a serial marry-er. Like the other guys in Minneapolis/St. Paul, Virgil likes to fish, drink beer, and get laid, and he does all of those in his second outing, while chasing after a serial killer.
The story starts off with a murder, there are a bunch more along the way, and it is twisty enough to keep most readers guessing until the Aha! moment close to the end. You will suspect before then whodunnit if you are paying attention. He gives fair clues.
Any of Sandford/Camp's books are worth reading, and if you can find them in paperback, start with the beginning and watch as Davenport grows -- it's quite the arc over twenty books or so.
Be interesting to see if he gives that-fuckin'-Flowers the same depth if he keeps these up.
Good read. Gets the gun stuff right. And when he was a reporter, he won the Pulitzer Prize.
