Edge of Darkness

Edge of Darkness is a British television drama serial, produced by BBC Television in association with Lionheart Television International and originally broadcast in six fifty-five-minute episodes in late 1985. A mixture of crime drama and political thriller, it revolves around the efforts of policeman Ronald Craven (played by Bob Peck) to unravel the truth behind the murder of his daughter Emma (played by Joanne Whalley). Craven's investigations soon lead him into a murky world of government and corporate cover-ups and nuclear espionage, pitting him against dark forces that threaten the future of life on Earth.
