I just finished listening to that one on audiobook. LOVED IT! It reminded me of the Zodiac murders in the SF Bay area.
I also enjoy his Agent Pendergast books with Lincoln Child. "Still Life With Crows" is my favorite. They aren't exactly deep, but they are a fun read.
I love to listen to certain authors - James Patterson and his 'Alex Cross' novels, Clive Cussler, and Tony Hillerman.
