Mystery! on PBS

Mrs. Bradley (Diana Rigg) probes the murder of a young woman who's found on a beach with her hair cut and a woven snake wrapped around her neck. It appears to be a ritual slaying; indeed, it's the same ritual used by the killer in Mrs. B's first case, some 30 years before. The setting is the home town of Insp. Christmas (Peter Davison), and George (Neil Dudgeon) has a tie to it as well: his daughter (Rebecca Callard), who is engaged to be married, works at a local inn.
