Simon Fenton, disillusioned ex-vicar and mild eccentric, is in the process of getting over the untimely death of his wife when he hears news of a mysterious legacy which also involves an alternative explanation about how his father, a gunner in the RAF Regiment, came to be shot in Northern Ireland during the Troubles. Natalie Roberson, a freelance high class call girl and aspiring airline pilot, is suborned to seduce him and help his adversaries cover up the story. Things go badly wrong and a corrupt detective is accidently killed. Simon and Natalie are forced to go on the run, hotly pursued by both the legitimate forces of law and order and darker forces under the direction of a senior politician who has everything to lose.
