On the second green of a Long Island golf-course there are three golf balls and a corpse with a bullet-hole in his forehead. The call goes out for Harry Fielding to come in from the cold. With a new suit and a new partner, Harry is back where he least wants to be: playing the deadly games of MI5. Always a triangular peg in a square hole, Harry has never felt easy with the protocol, the procedure and the need-to-know principles of the British secret service. And it doesn't help that his apprentice, Johnny Weeks, is a troublemaker. Going back to the work he hates but does so well, all Harry really wants is to rekindle his relationships with his ailing, amnesiac father and his ex-wife - who appears to be sleeping with his boss. Will this be his last chance: the fresh start that will restore moral equilibrium to a crooked man who wants to go straight?
