Happy Valley will bow out after three series with an extended finale, as the BBC braces itself for what will surely be one of the most watched TV shows of the year and fans get 10 minutes of extra action.
It was back in 2014, that the world was first introduced to Sarah Lancashire's now iconic character, Catherine Cawood, as the former Coronation Street star took on a role a million miles away from Rovers Return barmaid Raquel.
No nonsense cop Catherine quickly established herself as a character not to be messed with, as she tried to juggle some serious trouble both on the beat and at home. And the cause of much of that? Arch nemesis Tommy Lee Royce, the villain who raped and impregnated her daughter Becky, with Becky later killing herself after giving birth to son Ryan.
