The Scribe by Matthew Guinn

Post Civil War and racial tension has never been higher in Atlanta. A shunned detective is pulled back to Atlanta to solve some brutal murders that seem to be the work of a serial killer bent on making a statement about those who profit from a major exhibition coming to the city. He is paired with the first black policeman on the force who may be just a publicity stunt and could be considered a suspect himself.
Political intrigue, a fascinating time in this country's history and a good ole fashioned murder mystery make this one great read. You feel deeply for this troubled man who wants to avenge his family's hardships from the war and his own sad treatment from a city that he gave so much to. "The Scribe" reads like Caleb Carr mixed with "Copper" and asks the question - when a man has had everything taken away, will he still fight for what is right?
