In Angola the largest tank battle since the second world war is taking place. South African troops are battling to preserve apartheid. Thomas Dylan is sent to the front line. Ministers want MI6 to provide support, but discreetly. But death is soon much closer to home. After thirty years in British Intelligence Adam Joseff has retired to his stamp collection. His loyalty is beyond question. Until he is murdered in the Caribbean. Then the questions start. Has Joseff betrayed his country? Or has he been betrayed? And why was he so interested in an Angolan student young enough to be his granddaughter? As the Dylans start pulling the clues together they must confront death, betrayal and their own conscience. Then the politicians take over.
