The tale teller / Anne Hillerman.

Joe Leaphorn may have retired from the Tribal Police, but he finds himself knee-deep in a perplexing case involving a priceless artifact -- a reminder of a dark time in Navajo history. Joe's been hired to find a missing biil, a traditional dress that had been donated to the Navajo Nation. His investigation takes a sinister turn when the leading suspect dies under mysterious circumstances and Leaphorn himself receives anonymous warnings to beware -- witchcraft is afoot.
