Long Way Home — Eva Dolan

A man is burnt alive in a shed. No witnesses, no fingerprints - only a positive ID of the victim as an immigrant with a long list of enemies. Detectives Zigic and Ferreira are called in from the Hate Crimes Unit to track the killer, and are met with silence in a Fenland community ruled by slum racketeers, people-trafficking gangs and fear. Tensions rise. The clock is ticking. But nobody wants to talk.
