Even with all the twists and turns being thrown their way, eagle-eyed Happy Valley fans were not distracted and spotted a nod to the first-ever episode as the drama came to a nail-biting end. The gritty BBC One drama first burst onto our screens in 2014 when following her teenage daughter's suicide, Sergeant Catherine Cawood led a team of strong-willed police officers in West Yorkshire to solve cases in the area.
However, Catherine heard that Tommy Lee Royce, the man responsible for the brutal rape that impregnated her daughter Becky and drove her to suicide shortly after Ryan was born, is out of prison after serving eight years for drug charges and she soon became obsessed with finding the psychopathic character, unaware that he is involved in the kidnapping of Ann Gallagher.
But now, as they say, the rest is history and after a seven-year wait between series two and series three, viewers finally got to see one last stand-off between Catherine and Tommy following his dramatic escape from court.
