3AM on a frozen winter's night. A small craft skims the Thames closing in on London's most exclusive new riverside hotel. On board is a lone assassin, his target - Britain's most powerful new politician. In a nation threatened by extremist jihadis and torn apart by civil unrest, Vernon Rolt has been catapulted into government on an extreme anti-terror platform. Rolt's plans for a zero-tolerance crackdown on ethnic violence has touched a popular nerve. But his move into politics has made him some unlikely enemies, and British ex-servicemen - once his most committed supporters - now want him dead.
