Dance Hall of the Dead

When two high school boys disappear, Navajo tribal police officer Joe Leaphorn is faced with a difficult sleuthing job. As he starts his investigation, it soon becomes apparent that things are getting deadly. And he also finds that nothing is straight forward -- there seem to be multiple mysteries. Why are the FBI and DEA on the scene? Are the disappearances related to upcoming native religious ceremonies? And, what is going on at a nearby archeological dig and in an odd-ball hippy commune?

Pretty good neo-western crime fiction from back in the 1970's. I'll check out more Joe Leaphorn stories.
