Grantchester on Masterpiece

PBS | 9:00 pm

Season 6 draws to a close (with Season 7 already in production) with a finale that opens with the murder of a successful music producer. In a bizarre twist, Geordie (Robson Green) finds himself implicated in the ensuing investigation, which forces him to consider the possibility that Johnny (guest star Shaun Dooley), an old army buddy, could be the killer. Tom Brittney, Al Weaver and Tessa Peake-Jones also star.
