Vincent (2005)
S1E2 Episode Two
Edward Harper enlists Vincent's help to look into the murder of his son, who was stabbed to death at a nightclub. The main suspect is James O’Connor, a friend of Ian and the son of the club's owner, but the police can't take action against him because there's insufficient evidence. Complicating matters, the lead investigator on the case is DCI David Driscoll, who is now romantically involved with Edward's ex-partner.
