Just started Season 2, an explosive final for Season 1. This is about a career diplomat (Keri Russell) who is sent to the UK as US Ambassador, a UK warship appears to have been attacked by Russia. This is excellent, tense but on the short side, 8 episodes season 1, only 6 episodes season 2. It’s been renewed for a third season. Rufus Sewell plays her connected former ambassador husband.
