Nine Eleven

S4, E1: Fitz and his wife are back in the UK after 10 years living in Australia. Their brief visit for their daughter's wedding sees Fitz rediscovering old passions and keen to prove that he's still got what it takes. The lure of a new murder investigation proves irresistible. He joins forces with a new police boss to try and crack the random killing of an American comedian. Fitz is soon on the trail of a troubled ex-soldier, who - like him - is trapped in the past. Written by Cracker creator Jimmy McGovern and starring Lisa Eichhorn, Richard Coyle and Kieran O'Brien.
