It is rare for a cozy mystery to survive a decade. Usually, by the time a show hits double digits, the lead has been replaced three times, the village has run out of creative ways to kill people, and the viewers have moved on to the next big streaming hit. But Grantchester Season 10 is actually happening. It’s a bit of a miracle, honestly. When James Norton left his post as Sidney Chambers years ago, everyone thought the show was dead in the water. Then Tom Brittney stepped in as Will Davenport, and the cycle repeated when he made his exit. Now, we are firmly in the era of Rishi Nair as Alphy Kottaram, and PBS Masterpiece and ITV have officially greenlit the tenth outing of our favorite crime-solving duo.
The announcement came with a mix of relief and genuine curiosity. If you've been following the production cycle, you know that Season 9 was a massive transition point. We had to say goodbye to Will and hello to Alphy, all while keeping Robson Green’s Geordie Keating anchored as the grumpy, lovable heart of the show. Season 10 isn't just another batch of episodes; it’s a milestone that puts the series in the same legendary bracket as shows like Midsomer Murders or Vera.
Why Grantchester Season 10 is a Massive Deal for PBS Fans
Most shows lose steam when they swap leads. Grantchester didn't.
That’s mostly because the "buddy cop" dynamic between a vicar and a detective is just too good to mess up. In Grantchester Season 10, we are going to see Alphy Kottaram truly find his footing. In the previous season, he was the outsider. He was the guy who didn't quite fit the village's expectations, and he had to earn Geordie’s trust. Now, that trust is baked in. They aren't just colleagues anymore; they’re friends. And in a village where people are getting murdered behind every rose bush and inside every locked vestry, that friendship is the only thing keeping them sane.
The production team, including executive producer Emma Kingsman-Cliff, has hinted that this season will lean even harder into the changing social landscape of the 1960s. We are moving deeper into a decade defined by rebellion, fashion shifts, and a loosening of the strict moral codes that governed the earlier seasons. Alphy represents a more modern perspective, which naturally clashes with Geordie’s old-school, post-war sensibilities. It’s a goldmine for dialogue.
The Cast: Who is Staying and Who is Going?
Expect the heavy hitters. Robson Green is back. He basically is the show at this point. If Geordie Keating ever retired, the village would probably just collapse into a pile of unsolved cold cases. Rishi Nair is obviously returning as Alphy.

Then you have the supporting cast that makes the vicarage feel like a home. Al Weaver as Leonard Finch is arguably the best part of the entire series. His journey from a repressed curate to an independent business owner (running his café and halfway house) has been one of the most poignant LGBTQ+ arcs on television. Tessa Peake-Jones will be back as Mrs. C, likely still grumbling about the state of the world while secretly being the kindest person in Cambridgeshire. Kacey Ainsworth (Cathy Keating) and Nick Brimble (Jack Chapman) are also expected to return.
What Really Happened with the Season 10 Timeline
There was some confusion online about when filming would actually start. Because the UK and US broadcast schedules are often months apart, fans in the States sometimes feel like they’re living in the past.
Filming for Grantchester Season 10 was slated to begin in the UK in late 2024 and carry through into 2025. This means we are likely looking at a premiere date in the summer or fall of 2025 for UK viewers, with a PBS Masterpiece rollout shortly thereafter. The writers have been tight-lipped about the specific "big bad" or overarching mystery, but the formula usually involves a mix of standalone weekly murders and a season-long personal struggle for one of the leads.
Breaking the "New Vicar" Curse
Usually, when a show replaces its main character twice, it’s a sign of desperation. Think about it. Most procedurals fail after the first big swap. But Rishi Nair brought an energy that felt less like a "replacement" for Tom Brittney and more like a fresh start. Alphy’s background—being a man of color in a predominantly white, traditional English village in the 60s—adds a layer of social commentary that the show didn't have as much of in the Sidney Chambers era. It makes the stakes higher. It makes his interactions with the locals more complex.
In Season 10, expect to see Alphy’s past come back to haunt him a bit. We’ve seen hints of his family life and his hesitations about the priesthood, and this season is the perfect time to dive into why he chose this path in the first place.

The 1961 Context: A World in Flux
By the time we hit the events of the tenth season, the 1950s are a distant memory. The "Swinging Sixties" are starting to bleed into rural England. This isn't just about the music or the clothes; it’s about the law.
We are seeing the beginnings of shifts in how the police operate, and Geordie—a man who has always relied on his gut and, occasionally, his fists—is finding himself in a world that demands more "modern" policing. This tension between Alphy’s empathy and Geordie’s cynicism is going to be a primary driver for the plot.
- The Vicarage Dynamics: How does Alphy manage the household now that he’s fully settled?
- Geordie’s Home Life: Cathy has been coming into her own, and their marriage has survived more than most. Will they finally get some peace? (Probably not, it's a drama).
- Leonard’s Ambition: Will Leonard’s social work bring him into conflict with the authorities again?
Addressing the Rumors: Is Season 10 the End?
Every time a milestone season is announced, the "Final Season" rumors start swirling. As of now, there is zero official word that Grantchester Season 10 is the series finale. In fact, the ratings remain incredibly stable. PBS loves it because it’s a pillar of their Sunday night lineup. ITV loves it because it’s a reliable performer that sells well internationally.
As long as Robson Green wants to put on the trench coat and Rishi Nair is happy in the collar, there’s no reason the show can't go to Season 11 and beyond. The beauty of the format is that it can evolve. It’s a show about a place, not just a person.
Practical Tips for Catching Up
If you're late to the party, don't try to binge all 10 seasons in a weekend. You'll get "village fatigue." Instead, focus on the transition episodes. Watch the end of Season 4 to see Sidney leave, the start of Season 5 for Will's arrival, and the entirety of Season 9 to understand who Alphy is before Season 10 drops.

You can stream the back catalog on the PBS Masterpiece Prime Video Channel or the PBS app. If you're in the UK, ITVX is your best bet.
What to Watch While You Wait
Waiting for new episodes is the worst part of being a fan. If you need that specific British mystery itch scratched, look into Ridley (also starring Adrian Dunbar) or The Marlow Murder Club. They capture that same blend of scenic beauty and dark underlying secrets that makes Grantchester so addictive.
The most important thing to remember about Grantchester Season 10 is that it represents the show's resilience. It has outlived its original source material (the James Runcie novels) and carved out a life of its own. It’s no longer just an adaptation; it’s a TV institution.
Keep an eye on official casting calls and production stills that usually leak during the summer filming months. These often give away the guest stars for the season—and Grantchester is famous for having some of the best character actors in the UK pop up for a single, murderous episode.
To stay ahead of the curve, ensure your PBS Passport is active so you can access the episodes the moment they air. Often, members get early access to the full season binge, which is much better than waiting week-to-week if you hate cliffhangers. Also, check out the Masterpiece Studio podcast; they frequently interview Robson Green and the writers during the production cycle, offering behind-the-scenes tidbits you won't find in the standard press releases.
