This is the fascinating true life story of one of Ireland's most famous unsolved murders. It is the tale of how an innocent man was found guilty but insane of the brutal homicide of a young woman from a very prominent family. Told in superb period detail, Scapegoat contains a combustible mix of sex, class, bogus respectability and dark domestic secrets
