Catherine Cawood is back.

Filming for the third and final season of Sally Wainwright's hugely popular procedural drama Happy Valley is currently underway, and we cannot wait. The BBC series stars Sarah Lancashire as Sergeant Catherine Cawood, a police officer intent on bringing her daughter's rapist Tommy Lee Royce (James Norton) to justice while investigating crimes in her Yorkshire town. Yesterday, the BBC shared a first look of the upcoming final series with viewers, and also outlined the cast members reprising their roles, as well as some new additions. In their statement, the BBC said: "Sarah Lancashire returns to her iconic role of Sergeant Catherine Cawood for six new episodes, long discussed by Sally Wainwright and Sarah Lancashire as the final chapter of the Happy Valley story." They went on: "As previously announced, James Norton and Siobhan Finneran will also return for series three - as Catherine’s nemesis, the murderer and sex offender Tommy Lee Royce, and Catherine’s sister, the recovering addict Clare Cartwright, respectively. https://twitter.com/bbcpress/status/1483742124801769472

"Announced today, Con O’Neill will reprise his role as Clare’s recovering alcoholic boyfriend Neil Ackroyd. George Costigan will return as Nevison Gallagher, with Charlie Murphy as his daughter and Catherine’s police colleague Ann. They will be joined by other Happy Valley returning favourites including Derek Riddell as Richard Cawood, Karl Davies as Daniel Cawood, Susan Lynch as Alison Garrs, Rick Warden as Mike Taylor, Vincent Franklin as Andy Shepherd and Rhys Connah as Catherine’s grandson Ryan Cawood."

New additions to the cast include Amit Shah, Mark Stanley and Mollie Winnard who will all play "pivotal roles" in the show's final instalment. In terms of plot, the series will centre on the discovery of the remains of a gangland murder victim in the town's reservoir. Catherine's investigation into the case eventually brings her back to Tommy Lee Royce once more.
