Long Way Home

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.
