Halifax f.p. - Season 3 Episode 1 Déjà Vu

Jane has, for once, put work behind her and is living on a house boat where she has just finished writing a book. Visited by an old friend, Abe Levin, he asks her to assess Matthew Viney, an ex-patient accused of murdering his parents. Reluctantly, Jane returns to the big city, intent on spending just a few days on the case. As usual, things don't go as planned. Matthew's brother, Daniel, has recurring dreams where he is the murderer. This is impossible as he wasn't even on the scene - or was he?
