The latest and final series of Happy Valley has left viewers on the edge of their seats as it returns after years off the air.
Sarah Lancashire plays Catherine Cawood, a police community officer for the West Yorkshire Police Department, in the BBC cop 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.
Following the gritty drama, many fans are concerned that a throwaway scene could hint towards the demise of a fan-favourite character. Fans have picked up on the frequent references to Catherine's upcoming retirement, which they worry hints at her death in the upcoming season finale.
