Another great one could be 'Winter in the Blood' by James Welch. Although it's not strictly a traditional private investigator story in the sense of a typical detective plot, it has elements of self - discovery and investigation within the context of an American Indian's life. The protagonist tries to make sense of his past and the events around him, which is somewhat like an internal investigation.
There is also 'Tracks' by Louise Erdrich. This novel has complex characters and a plot that involves the exploration of relationships and secrets within an American Indian community. While not a classic private eye story, the characters are constantly seeking truth and understanding, much like what a private investigator would do.
