Filming has begun in West Yorkshire on the third and final series of the BBC One crime-drama Happy Valley, with Sarah Lancashire reprising her role as Sergeant Catherine Cawood.
The final season of writer-creator Sally Wainwright's multi-award-winning series will consist of six episodes, with Irish director Fergus O'Brien (Gentleman Jack, Mother's Day, Against the Law) joining Patrick Harkins (Guilt, Tin Star, Hollyoaks) behind the lens.
Releasing a first-look photo on Wednesday, the BBC said: "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.
"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.
"Amit Shah (The Other One, The Long Call), Mark Stanley (The Girl Before, White House Farm) and Mollie Winnard (All Creatures Great and Small, Four Lives) join the cast for series three, and will play pivotal roles in Happy Valley's final chapter."
Teasing what's ahead, the broadcaster added: "When Catherine discovers the remains of a gangland murder victim in a drained reservoir it sparks a chain of events that unwittingly leads her straight back to Tommy Lee Royce.
"Her grandson Ryan is now 16 and still living with Catherine, but he has ideas of his own about what kind of relationship he wants to have with the man Catherine refuses to acknowledge as his father.
"Still battling the seemingly never-ending problem of drugs in the valley and those who supply them, Catherine is on the cusp of retirement."
