Brilliant first episode which didn't disappoint after the previous series. Tommy is a monster, but the series is so well written that I had started to feel a bit sorry for him when we saw his Mother and how he had grown up. This to me is the sign of good writing, as it is when Sarah Lancashire faces from day to day policing with muttered asides and black humour; it would be a bit weird if she pronounced everything she said clearly and precisely! We just click on the subtitles, not because of the accents, but to pick up the muttered, under the breath asides!
