ITV’s latest hit period drama, Grantchester, will be returning for a second season. The six-part mystery that stars James Norton as Sidney Chambers, a charismatic clergyman who turns investigative vicar, has been reupped by the network for a further season to shoot next year. Set in the 1950s and co-starring Robson Green as down-to-Earth Police Inspector Geordie Keating, Grantchester has found a faithful following in Britain. Its first season concluded earlier this month and averaged a consolidated 6.6M viewers and a 24% share. It aired Monday nights at 9 PM.

U.S. viewers will get their first taste of Season One when it begins airing on PBS’ Masterpiece on January 18 at 10 PM, with Downton Abbey as a lead-in.

The second season of Grantchester, a Lovely Day and Masterpiece co-production for ITV, will be produced in London and Grantchester, the real Cambridgeshire village where the series is set. As with the first season, the second will be based on the books by James Runcie, in particular the stories within the author’s second Grantchester Mysteries novel, Sidney Chambers And The Perils Of The Night. Daisy Coulam will return to adapt Season 2.

Lovely Day’s Diederick Santer is executive producing with Shine International handling world rights. Here’s a trailer from the first season:
