Groundbreaking environmental-espionage shocker Edge of Darkness (1985) begins routinely enough but then ratchets the suspense to levels that would have turned Hitchcock green with envy. Emma Craven (Joanne Whalley in her first starring role) is a young environmental activist killed in mysterious circumstances. Emma's father Ron Craven (Bob Peck in a star-making performance) will not be silenced and, as a police detective, is uniquely positioned to pursue his own unofficial investigation. He moves from grief to a determination to find the truth, all the while advised and comforted by Emma, but is she a ghost or a manifestation of his haunted psyche? Craven digs deeper, uncovering labyrinthine conspiracy in the nuclear industry and, as the body-count rises, encounters the garrulous CIA agent Darius Jedburgh (a superb Joe Don Baker) with a mysterious agenda of his own. Accompanied by a haunting musical score by Michael Kamen and Eric Clapton, Edge of Darkness builds on the legacy of Tinker, Tailor, Soldier, Spy and Smiley's People to become quite simply the best television thriller ever.
