Adapted from the Grantchester Mysteries novels by James Runcie and already renewed Grantchester for series seven, Grantchester features a wide ensemble cast.

Speaking to RadioTimes.com and other press, Tom Brittney teased a “shock” romantic storyline for Reverend Will Davenport.

Meanwhile the new season also promises to be the “most powerful” instalment yet, according to Robson Green, as Grantchester season 6 sees Geordie and Will “torn apart”.

Read on for everything you need to know about the cast and characters in Grantchester.

Tom Brittney plays Will Davenport

Grantchester

Who is Rev Will Davenport? A motorcycle-riding vicar who previously replaced James Norton’s Sidney Chambers as Grantchester’s resident sleuthing man of the cloth. In series five, Will’s (self-imposed) vow of celibacy was broken (with a nun, no less). At the start of season six, he’s at Merries Holiday Camp, where’s he’s able to let his hair down.

Talking about his character’s season six arc, Brittney said: “I’m sexually liberated… and the minute I suddenly start to relax at this holiday park, and I maybe think that there’s a girl that I have feelings for, it all comes crashing down in quite a dramatic fashion. And I think that maybe puts me off the idea for a bit. I’m trying to think of what… how much I can say about my… romantic storyline.”

He continued, “There is more. It’s quite shocking. There’s a will-they-won’t-they kind of thing, but it’s a bit shocking who that person may be.”

Where have I seen Tom Brittney before? You might recognise Brittney for his role as Lieutenant Jeremy Foster in the time-travelling series Outlander. He has also appeared as American Tyler Mitchell in the BBC’s Lottery drama The Syndicate, and as the rapist Roger Lockwood in UnReal.

Who is Geordie Keating? A gruff police detective and best friends with Will, he’s married with children. In previous seasons his marriage to Cathy was on the rocks following his affair with a colleague, but it’s now firmly back on track.

Robson Green has teased that the relationship between Geordie and Will will become “incredibly volatile” during the sixth season.

“It’s all about Geordie not seeing the world how Will sees it and Will not seeing the world how Geordie sees it and conflict occurs,” he explained.

“Will sees the world how it ought to be whereas Geordie’s philosophy is that marching for peace is about as much use as praying for it, he doesn’t believe that we can sort problems out by confiding in an invisible friend. This causes real problems between Will and Geordie.”

Where have I seen Robson Green before? One half of ’90s singing duo Robson and Jerome, Green’s television CV includes prominent roles like Dr Tony Hill in Wire in the Blood and Dave Ticket in Soldier Soldier; more recently he played Teddy in BBC One drama Age Before Beauty. He’s also fronted numerous fishing programmes, including Robson Green: Extreme Fisherman.
