In the early 1970s, Sir Maurice Oldfield of the British Secret Service, MI6, embarked upon a decade-long campaign to derail the political career of Charles Haughey. The English spymaster believed Haughey was a Provisional IRA godfather, therefore, a threat to Britain. Oldfield was assisted by unscrupulous British agents and by a shadowy group of conspirators inside the Irish state’s security apparatus, all sharing his distrust of Haughey. Escaping scrutiny for their actions until now, Enemy of the Crown examines more than a dozen instances of their activities.
