Following the end of WWII, the Atlanta Police Force reluctantly added eight African American police officers. Their beats were restricted to Darktown, the part of Atlanta without streetlights, and it almost goes without saying, without white people. Two recently hired war veterans, Lucius Boggs and Tommy Smith, stumble across an inebriated white man with a young black woman in his car. After they see her get punched and then escape from her driver they later find her body buried among trash in a vacant lot. Superficially, the novel is a 1940s murder mystery in the south, but the real story is the unflinching detail with which we observe Boggs and Smith endure Jim Crow. They are forbidden from arresting criminals, only white officers can, so they must subdue adversaries, run to a telephone, and call for a squad car whose white officers may or may not arrive. They may not question, nor even look into the eyes, of white officers, or for that matter, white men. They may not be seen alone with, nor speak to white women without fear of subsequent lynching. Boggs and Smith choose to uphold the law where they can while circumventing a white police force that alternately extorts, threatens, shoots, and convicts Atlanta’s blacks and despises its colored comrades. As with most elements of Jim Crow I don’t know whether I am more offended by the inhumane behavior of America’s white racists or the fact I was never taught anything about Jim Crow at any point in my education. The heat in this extremely well written mystery is as intense as a breezeless summer day in Atlanta. The audio version of this book is excellent.
