It's a stand alone series, but by the same writers, on the same premise - an innocent person being let out on appeal, but wanting to clear their name and find the real killer.
This time it's set in Keswick, Katherine Kelly plays a schoolteacher accused of murdering her teenage pupil because they were (allegedly) having an affair. She gets out but the locals are still against her as they all believe the grooming allegations. It was so good Al, well worth watching. I guessed the real murderer by the second episode
Vic, it was excellent
