It's Manchester's hottest summer on record and while Callum Innes evicts families on behalf of local slum lord Donald Plummer, the English National Socialists stir up racial tensions to breaking point. A firebomb attack at a Plummer property thrusts Innes into the spotlight as he saves a child from the burning building. But when Plummer enlists his help to track down the arsonists, Innes finds himself dealing with more than the ENS and his rapidly overwhelming codeine addiction. Time's running out and the temperature keeps rising. Manchester needs a hero and Callum Innes is the closest it has.
