Murder is only one element in this debut mystery, which also takes on interracial romance, the exploitation of Indian lands and the political ambitions of a former county commissioner who's also a gubernatorial candidate. Father John O'Malley has been banished from Boston to the dirt-poor mission at Wyoming's Wind River Reservation to recover from his alcoholism. When the tribal chairman is killed, an obnoxious FBI agent arrests the chairman's nephew. In an effort to help, Father John joins forces with Vicky Holden, a feisty, 40-something Arapaho attorney for whom he stoically suffers an unpriestly attraction. Into this modestly suspenseful tale, Coel (Chief Lefthand) weaves often insightful commentary about Arapaho culture, bigotry and the widespread alcoholism among Western tribes. Likable, well-drawn characters and a lively pace mark this novel.
