Ernie O'Malley's life is the stuff of a big screen film - in a sense it was, as a central inspiration to The Wind That Shakes The Barley. A young medical student at the time of the Rising, he became a key link between the IRA GHQ in Dublin and the army in the field. He was also a key figure in Dublin's bohemian art scene, together with his wife Helen Hooker. My guest is Cormac O'Malley. Ernie O'Malley: A Life is out now from Merrion Press.
