1969 was a year of rising tension, violence and change for the people of Northern Ireland. Rioting in Derry's Bogside led to the deployment of British troops and a shortlived, uneasy truce. The British army soon found itself engaged in an undercover war against the Provisional IRA, which was to last for more than twenty years.

In this enthralling and controversial book, Martin Dillon, author of the bestselling The Shankill Butchers, examines the roles played by the Provisional IRA, the State forces, the Irish Government and the British Army during this troubled period. He unravels the mystery of war in which informers, agents and double agents operate, revealing disturbing facts about the way in which the terrorists and the Intelligence Agencies target, undermine and penetrate each other's ranks.

The Dirty War is investigative reporting at its very best, containing startling disclosures and throwing new light on previously inexplicable events.
