Innocent Graves: Part 1 (S02E05)

Frustrated that a number of cases have been knocked back by the Crown Prosecution Service, Banks and the team are called on to investigate the murder of teenager Ellie Clayton, daughter of a high-profile internet entrepreneur. The victim's background, together with the suggestion she may have been raped, means the incident is soon the subject of much media speculation, and strong evidence implicates a theatre director who ran a drama workshop the girl attended on the night she died. The detective believes he has found his man, but Morton fears her colleague isn't seeing the bigger picture. (iTunes)
