It was rare for all of us at home to agree on something to watch, but this suspenseful series definitely became one of those exceptions as its intensity grew over its six-week run. The story begins when police officer “Craven” (Bob Peck) is driving his daughter (Joanne Whalley) home, only to have her shot in the driveway. Overcome with grief, he’s certain that it was meant to be an attack on him but soon after, a mysterious government agent named "Templeton" (Charles Kay) approaches him and suggests she may have been the intended target all along. The reason? Apparently, she was involved in activism and part of a group that had infiltrated a nuclear research facility hidden within abandoned Yorkshire mines, uncovering something both incredibly valuable and illegal. He’s then teamed up with CIA operative “Jedburgh” (Joe Don Baker), who has his own ideas about what happened, is happening, and might happen if they can't uncover the truth behind a complicated web of deceit involving people in business and defense. I felt that Troy Kennedy Martin’s writing and story, combined with Peck's strong performance, developed into a sharp commentary on the risks associated with British, and potentially worldwide, nuclear policy during the 1980s. Kay and Ian McNeice’s portrayal of lawyer “Harcourt” also adds to the sense of a government hardened by corruption and fear, and both the close-up, often dark lighting, and a pervasive feeling of dread contribute effectively to its intricate and believable ending. I might be alone in this opinion, but I didn't care for the Eric Clapton soundtrack, particularly as it became too prominent later on; however, that’s a minor point. Peck and JDB both deliver convincing performances, with the latter bringing a touch of dark humor and an air of suspicion to his role. By the time the series concluded, I found myself questioning whether anyone in power was capable of understanding, or even telling, the truth—or if I even wanted them to. This exemplifies what the BBC can achieve, and it's certainly worth watching all at once.
