1. It’s set 18 months later

Cast and crew have been spotted in Yorkshire shooting scenes for the new six-part series of the gritty ITV drama, which will see Sarah Lancashire returning as no-nonsense police sergeant Catherine. The new series may see killer Tommy Lee Royce (James Norton) firmly behind bars, but there are still troubled times for Catherine as she suspects there may be another serial killer on the loose. In the finale of the first series Catherine was brutally beaten in a basement - leading some to question if the drama was too bleak and gratuitous. However, as these images show it would appear that the 2nd series doesn't pull its punches as Sarah was seen in character sporting cuts and bruises to her face.

Tommy Lee Royce (James Norton) is in prison, Catherine (Sarah Lancashire) continues to fight crime, and the enemies come face-to-face once again.

2. The Valley still isn’t Happy

When asked how to describe the new series, Sarah stated: ‘emotionally brutal,’ which yep, sounds good to us. ‘The whole thing is draining simply because of [Catherine’s] disposition, because she wears her emotional state of mind everywhere,’ she continued.

3. It almost didn’t happen at all

‘I was nervous and wasn’t sure we should be doing it,’ Sarah confessed about the second series. ‘But when I read them [the scripts], I thought – she’s pulled it off.’

4. Accuracy is key

Sarah also revealed the shows success comes mainly due to the accurate representation of a female police officer, revealing: ‘It’s all down to Lisa Farrand, who’s our police advisor, and who Catherine is really based on. The first thing she said to me was: “You’re going to have to man up.”’ We’re loving your work, Lisa!

5. There are new characters!
