Happy Valley has returned to BBC One for its third and final season, six years after it last appeared on our screens.
Oldham lass Sarah Lancashire stars as Sergeant Catherine Cawood in the gritty police drama. The third season sees Catherine discover the remains of a gangland murder victim in a drained reservoir, which sets off a chain of events and leads her to Tommy Lee Royce, the man who raped her daughter.
Her grandson Ryan is now sixteen and is starting to question what kind of relationship he should have with his father. Sarah has had an illustrious career on screen - but has also battled plenty of personal hardships while in the spotlight.
