The official synopsis for Season 2 reads: “…we join Catherine, the no-nonsense police sergeant who is back heading up her team of dedicated police officers in The Calder Valley in West Yorkshire.

“With Tommy Lee Royce (James Norton) firmly behind bars, Catherine suspects there may be another serial killer on the loose and makes a gruesome discovery that will have shocking repercussions for her and her family.

“Meanwhile, a new detective, DS John Wadsworth (Kevin Doyle) arrives on the block with his own set of problems, and despite being firmly under lock and key, Tommy forms a bond with a mysterious female admirer (Shirley Henderson).”

The first season launched in April 2014 and pulled in a weekly consolidated audience of almost 8 million viewers.
