The third stunning new Tom Buckingham thriller from the bestselling author of Bravo Two Zero.     3 AM 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 just 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 -- British ex-servicemen, once his most committed supporters who now want him dead.     Ex-SAS trooper turned MI5 operative Tom Buckingham is undercover inside Rolt's organisation. His mission: to neutralise the rogue assassins for whom he also has become a target, and to discover the deadly intentions of Rolt's new financier, shadowy Crimean oligarch Oleg Umarov. But all too soon, Tom gets caught up in a far more devastating plot which will change the political landscape of Europe -- for ever.
