Abu Al Zachari lands in Greece, holding a small child, posing as a refugee. In truth, he is Syrian, trained by the Afghans, and a vicious terrorist. Al Zachari travels to the north of England where he begins to plan the biggest terrorist atrocity ever seen in the UK. Everything is going to plan, until a teenage boy, radicalised by Zachari, is found tortured and murdered near a burning mosque. Mohammed Hussain is hanging from a meat-hook with a sign around his neck that announces his crime....'Terrorist.' Detective Sergeant Ewan Striker is called in to investigate. Can Striker prevent the horror that Al Zachari is planning? And exactly who is murdering radicalised British kids?
