In the final part of his trilogy exploring ‘The Troubles’ in Northern Ireland, Peter Taylor talks to undercover agents of the British state and reveals for the first time the hidden secrets of the war they waged against the IRA for thirty years. PROVOS and LOYALISTS told the story of the conflict from the point of view of the Republicans and Loyalists; now the story, with all its tragic twists and turns, is told from the British perspective. For the first time, undercover soldiers, Special Branch officers and a top MI6 agent step out of the shadows and, along with the Whitehall mandarins who helped shape policy from Westminster, tell their stories.
