The McMafia star has headed back to the titular 1950s village with Robson Green (Detective Geordie Keating), alongside returning cast including Al Weaver, Tessa Peake-Jones and Kacey Ainsworth.
Executive producer Rebecca Eaton said Norton’s departure would be “bittersweet” for Grantchester viewers, but added that the series would continue with a new vicar.
“It’s a bittersweet time for Grantchester fans, who will be cheering the return of the series but crushed to say goodbye to James,” she said. “We want to assure them that the series they love will continue with brilliant new episodes and a captivating new vicar.”
Filming will take place in London, Cambridge and, of course, Grantchester itself.
