Billy Keane examines the notorious unsolved murder in 1958 that inspired his father John B Keane's acclaimed play. The Field was first performed at the Olympia Theatre in 1965, just seven years after the death of Moss Moore in rural Kerry had shocked the nation. The programme explores how the character of Bull McCabe was inspired by a man suspected of the murder but never charged, who was ostracised by his community. Featuring contributions from Jim Sheridan, who directed the Oscar-nominated 1990 movie adaptation
