Happy Valley has ended for good but there was one tiny moment when lead character Catherine Cawood gave a subtle shout out to another legendary BBC cop drama in the closing scenes.
As Sarah Lancashire and James Norton finally came face-to-face as their characters, Cawood and Tommy Lee Royce, the Yorkshire copper was forcefully explaining why she had beat Royce up on his barge in series one.
The pair were having a back and forth about the criminal's violent past and list of crimes when Catherine shouted at him for beating her up. To which Royce replied: "“You kicked the shit out if ME on that barge." And Catherine's response saw her namecheck fellow BBC cop show Line of Duty which also has a huge following. She said: “Yeah in the line of f*cking duty not because I’m a brain dead psychopath who thinks it’s an afternoon amusement!”
