The official synopsis for Season 2 reads: “…we join Catherine (Sarah Lancashire), the altruistic and forthright police sergeant who is back heading up her team of dedicated police officers in The Calder Valley in West Yorkshire.

“Tommy Lee Royce (James Norton) is now behind bars, but continues to haunt Catherine as she rebuilds her life. There are suspicions that a serial killer is behind a spate of murders and Catherine makes a gruesome discovery that has shocking repercussions for her and her family.

“Meanwhile, Detective Sergeant John Wadsworth (Kevin Doyle) has his own set of problems, and despite being in prison, Tommy forms a bond with a mysterious female admirer (Shirley Henderson).”

Created by Last Tango in Halifax writer Sally Wainwright, Happy Valley launched in April 2014 and pulled in a weekly consolidated audience of almost 8 million viewers.
