Sarah Lancashire will return as Sergeant Catherine Carwood for the final chapter of the Happy Valley story. On the announcement of the new series, Lancashire said: “It’s time to let the dog see the rabbit.”

James Norton will return as murderer and sex-offender Tommy Lee Royce, and Siobhan Finneran will return as Catherine’s sister, Claire.

Norton said: “To take on Tommy one final time is a wonderful and daunting privilege, and something I’ve been looking forward to since we wrapped the last series, 6 years ago. I’m so excited to be working with the insanely talented Sally and Sarah again. Thinking we should all go on one last barge holiday, for old times’ sake.”
