Marylebone, November 1968. Detective Sergeant Breen has a death threat and two burned bodies on his hands. One is an un-mourned vagrant; the other the son of a politician. One case suffers the apathy of the police; the other obstructed by a PR-conscious father. Then the potential perpetrator of his death threats is murdered. Banished from a corrupt system, Breen is finally forced to fight fire with fire.
