Calling all fans of Grantchester! The much-loved detective series is returning for its tenth season, promising even more intrigue, unexpected twists and a touch of romance.

The tenth series began filming in July last year, and while the first episode just hit screens in the US, audiences in the UK are still awaiting a release date.  

Based on a collection of short stories by James Runchie, the ITV period drama sees the return of Robson Green as DI Geordie Keating, as well as season nine's Rishi Nair as Reverend Alphy Kottaram.

While UK fans eagerly await its release, here's everything we know about Grantchester season 10…

What is Grantchester season 10 about?

As the tenth series takes viewers back to the sleepy town of Grantchester, Alphy and Geordie are quickly drawn into a new case as they investigate a suspicious death during Easter festivities. 

Season ten also promises to delve into Alphy's backstory, while the partnership between Geordie and Alphy grows.

The official synopsis reads: "As DI Geordie Keating (Robson Green) and Reverend Alphy Kottaram (Rishi Nair) continue to work together as a crime-solving duo in scenic Grantchester, they must also support each other through changing times, family struggles and personal secrets. 

"This season, Alphy feels like he’s found a home, but he’s forced to confront secrets he’s kept close to his chest. Will he be able to let anyone fully in, or must he confront truths about himself first?"
