Talking God by Hillerman, Tony

Reunited by a grave robber and a corpse, Navajo Tribal Police Lieutenant Joe Leaphorn is trying to determine the identity of a murder victim, while Officer Jim Chee is arresting Smithsonian conservator Henry Highhawk for ransacking the sacred bones of his ancestors. But with each peeled-back layer, it becomes shockingly clear that these two cases are mysteriously connected—and that others are pursuing Highhawk, with lethal intentions. And the search for answers to a deadly puzzle is pulling Leaphorn and Chee into the perilous arena of superstition, ancient ceremony, and living gods.
