An in-depth study of the most significant Irish clergyman in the history of the state. For three decades, 1940-72, as Archbishop of Dublin and Primate of Ireland, John Charles McQuaid imposed his iron will on Irish politicians and instilled fear among his clergy and laity. No other churchman amassed the religious, political and social power which he exercised with unscrupulous severity. An admirer of the FBI's J. Edgar Hoover, Archbishop McQuaid built up a vigilante system that spied on politicians and priests, workers and students, doctors and lawyers, nuns and nurses, soldiers and trade unionists. There was no room for dissent when John Charles spoke in the name of Jesus Christ. This power was used to build up a Catholic-dominated state in which Protestants, Jews and feminists were not welcome.
