In 2016, Thomas Mullen delivered one of the crime novels of the year with Darktown. That book told the story of the first Black policemen in Atlanta, a force established in the years following World War II. Darktown showed the institutionalised racism that sat behind and around that decision. The group of eight policemen were set up in a basement of the YMCA with no vehicles and if they wanted to arrest someone they had to call the white police to do it. They were only allowed to patrol the predominantly black areas of town and while they were feted for the steps they were taking they were also feared in their own community. Darktown was in other respects a straight down the line procedural in which two of the black policemen and one white policeman work a murder case from different angles. Lightning Men picks up a couple of years after the events of Darktown. Like its predecessor it focusses mainly on the black police partners of Boggs and Smith and their former co-conspirator Deny Rakestraw but it also ranges across a broader cross section of characters. Each of the three main characters have their own problems to work…

A crime novel set in Atlanta in 1948, Darktown uses the genre to shine a light on a point in time in American history and, in doing so, on present day America. Thomas Mullen uses as his jumping off point the true story of the appointment of the first eight black policemen in Atlanta. They do not have an office, instead they are forced to operate out of the basement of a local YMCA. They were not given cars and had to call in white detectives when a matter needed investigation. Distrusted almost as much by the locals in their own, segregated neighbourhoods as by their fellow police officers, they were nevertheless part of the vanguard of a nascent civil rights movement. Lucius Boggs, son of the local preacher and recently returned from the Second World War, is one of the first eight black policemen in Atlanta. He and his fellow recruits are keen to clean up their part of town, rife with bootleggers, gambling and prostitution. To add to their problems, many of those enterprises are either sponsored or actively managed by their white police colleagues who make money from turning a blind eye and who are not keen to see any change to the…
