Happy Valley writer Sally Wainwright has revealed how Sarah Lancashire helped shape the explosive climax to the final series. In her first television interview, she told Newsnight how the actress who played Catherine Cawood came to her home because she wasn't happy about the ending.
They spent a day talking it through, and Sally made some changes to the outcome. The final on Sunday (February 5) drew the largest audience according to ratings for a drama on UK television since the Line of Duty series finale aired.
It ended with a tense confrontation between Catherine and killer Tommy Lee Royce over the kitchen table in her home. Writer Sally taught all of us Happy Valley conspiracy theorists a lesson and ended the Yorkshire-set drama with a satisfying twist.
