Tony Hillerman detective series of books weaves old and modern Indian culture, folklore and superstitions into solving murder mysteries on the reservation in the southwest. The setting for 18 of Hillerman's books are the Navajo reservation and the main characters leading the investigation are the Tribal police. Having lived in northern Arizona for a number of years, Indian culture and folklore are very near to my heart. Hillerman does an great job weaving a modern murder mystery into cultural traditions and supersticions.
