Examining the work of these authors, Stephen Soitos frames his analysis in terms of four uniquely African American tropes: altered detective personas, double-consciousness detection, black vernaculars, and hoodoo. He argues that black writers created sleuths who were in fact "blues detectives," engaged not only in solving crimes, but also in exploring the mysteries of black life and culture.

Soitos grounds his study in African American literary theory, particularly the work of Houston Baker, Bernard Bell, and Henry Louis Gates, Jr. He offers both a new way of conceiving black detective fiction and a series of insightful readings of books in this genre.
