Skeleton Man

Joe Leaphorn, former Navajo tribal police lieutenant, is not a happy retiree. So when his successor asks him to look into how a young Hopi named Billy Tuve came by a valuable diamond the boy tried to pawn for a fraction of its worth, Joe finds himself involved in a five decade old mystery. It dates back to a plane crash in the Grand Canyon, one that took the life of a man whose putative daughter also has an interest in the diamond; it could lead her to her father's remains, from which she hopes to extract enough DNA to establish her birthright. For good measure, Hillerman adds a couple of villains determined to beat her to the site of the crash, a cache of other diamonds long since given up for lost in the Canyon's watery depths, and a Hopi ritual that's kept the site secret for years.
