Dance Hall of the Dead by Tony Hillerman

The second in Hillerman's Navaho tribal police series. Listened to it while running; being a Hillerman veteran, I was able to identify the killer fairly quickly, but the mystery isn't the best part of Hillerman. It's his development of Joe Leaphorn and his insights into Navaho culture.

The Deep by Peter Benchley

A good, short adventure story by the author of Jaws.
