Lucas Davenport pursues a prolific serial killer who has gone undetected for years in the newest nail-biter by best selling author John Sandford. It was a relatively minor criminal matter, but enough that the U.S. Marshals obtained a warrant to enter the home. They didn't expect to unearth trophies from a score of killings. Now Davenport is on the trail of a serial murderer, one who was able to operate for years without notice or suspicion. But there's even more to this killer than meets the eye.
