This is one of my favorite shows -- most of the time. Roger Allam and Nancy Carroll are a marvelously mature but amusing couple. My one dislike about the show is the appearance of John Light in one episode (at least I HOPE it is only one.) His character is vicious and sadistic beneath a pose of charm and sophistication. The brutality of his behavior is in stark contrast to everything else I've seen of the series so far. Please, please don't bring him back!
