Killing for England - Iain McDowall

Chief Inspector Jacobson and DS Kerr had been on leave when the body of a young black man, Darren McGee, had been fished out of the River Crow. The autopsy had pointed to suicide by drowning. But now Darren's cousin, Paul Shaw, is in town: a top-notch investigative journalist with an axe to grind and a claim that Darren had really been the victim of a racially-motivated murder.

Jacobson isn't convinced.
But when Paul Shaw turns up as dead and as terminally-wet as his cousin, Jacobson and Kerr are faced with a baffling double-murder to investigate. And a dangerous confrontation lies ahead with the murky world of the Far Right.
