New Tricks: Season 11, Episode 9

11 - 9: Breadcrumbs

Ellen Barker is murdered, a cold-crime enthusiast. At her home, a photo of Dan Griffin is found, so he is the prime suspect. The team soon find out the pair were friends. Sasha comes into contact with DCI Grace Mackie, a ex-colleague from their Hendon training, to help them tackle the case. Griffin assumes that the last case Ellen was looking at could lead to clues about her killer, heading to Minchampton, where a woman called Sally was murdered 25 years ago.
