The Wailing Wind by Tony Hillerman - old hardcover

Officer Bernadette Manuelito found the dead man slumped over in the cab of a blue pickup abandoned in a dry gulch off a dirt road—with a rich ex-con's phone number in his pocket ... and a tobacco tin nearly filled with tracer gold. It's her initial mishandling of the scene that spell trouble for her supervisor, Sgt.

Years earlier, Leaphorn followed the trail of a beautiful, young, and missing wife to a dead end, and his failure has haunted him ever since.
