Devil in a Blue Dress by Walter Mosley

This book begins with black and white ideas of righ and wrong, and somehow before the last page, the entire world around the reader has turned to a shade of grey.  The standard mystery genre format allowed Mosley to discuss social construction and morality in an entertaining fashion.  The over all ideas that create a person, specifically a woman, into a devil, and the plot twists, made this a book to be binged on.
