This was the third book from the Davenport series that I have read and easily the best. I liked the feeling of impending doom with the main characters racing against time to catch the killer before he can strike again and before one of the investigators dies of cancer. The eventual solution of this pending collision caught me by surprise. And, in case this wasn't enough, Sandford threw in a locked room murder mystery as a clever subplot. If anyone in Hollywood ever wants to bring a Lucas Davenport thriller to the screen, this would be a good one to start with.
