Sacred Clowns is the eleventh crime fiction novel in the Joe Leaphorn / Jim Chee Navajo Tribal Police series by Tony Hillerman, first published in 1993. Murders happen on both the Navajo reservation and the Tano Pueblo. One happens during a Tano ceremonial, with the koshares (sacred clowns) and kachinas performing. Leaphorn is in charge of a new investigation unit, with Chee as his sole staff support.
