Season 3 of “Grantchester” saw Sidney Chambers and Geordie Keating investigate the murder of a doctor and a cryptic crow. This was augmented by the interpersonal drama of the two characters. Sidney has grown disillusioned with his priesthood, and his feelings for Amanda Kendall (Morven Christie) begin to affect his decision-making. Meanwhile, Geordie is caught in an affair. The season eventually came to a satisfactory conclusion but it also saw James Norton exit the show.
In an interview with PBS, Norton stated, “It was a combination of things; the Amanda storyline tying up as it did with her and Sidney breaking up and him choosing the church in the third series felt like a natural conclusion to Sidney’s story. Then when the possibility of a fourth series came along, the decision was whether or not to start a whole new journey for Sidney. Rather than do that it felt like it would be better to hand over the baton to someone else and give Grantchester a fresh injection of energy.”
Ultimately, the story continued on, and his replacement, William Davenport, was able to successfully fill his shoes as the character also got to befriend Geordie. Norton continues to work in film and television, and has recently starred in “The Nevers,” “Things Heard and Seen,” and “Nowhere Special.”
