Deceiver, Paperback/Frederick Forsyth

Sam McCready is The Deceiver , one of the Secret Intelligence Service's most unorthodox and most valued operatives, a legend in his own time. The end of the cold war has, however, strengthened the hand of the Whitehall mandarins, to whom he seems about as controllable as Genhis Khan, so Sam is to have his fate decided at a special hearing.
