The Marlow Murder Club season 3: Release date and latest news

As the current season of Death in Paradise heads rapidly towards its end, fans can look forward to return of another show from the same creator – The Marlow Murder Club.

Robert Thorogood's U&Drama show, based on his series of novels, stars Samantha Bond, Jo Martin, Cara Horgan and Natalie Dew, with all four returning for this new run of mysteries.

As always, the central cast are joined by a host of guest stars, with Doctor Who's Peter Davison and EastEnders's Nigel Harman amongst them this time, as we also learn more about the personal lives of the central characters.

This time, there is also added jeopardy for one of the titular trio, as Horgan's Becks finds herself the suspect in an investigation.

But when will the new episodes air and what else do we know about the new season? Read on for everything you need to know about The Marlow Murder Club season 3.

Will there be a The Marlow Murder Club season 3?

There will! The show's renewal was confirmed back in May 2025, with Claire Hookway, commissioning executive for UKTV, saying in a statement: "Following the huge success of the first two series, we’re thrilled to return with another instalment where Judith, Suzie, Becks, and our police team are faced with three puzzling new mysteries to solve.

"We’re excited to treat the audience to more joyous fun in the beautiful town of Marlow, with many surprises and clever twists in store."

The news was hardly a surprise - the series has proved consistently popular with viewers, while the cast had routinely expressed interest in returning to solve more cases.

Speaking with RadioTimes.com and other press on the set of season 2, Tanika star Natalie Dew gave her own thoughts on what she would want to see in future episodes.

"I always want to go somewhere," she said. "I said this in season 1, I was like, 'Why does Rob [Thorogood] not write this one in Barbados?' I would love it. I always fantasise."

She continued: "Sometimes I think it would be so good to do a Christmassy one. Because that would be really nice here, and then we could go to the nice pubs and have the snow and the fires and all that sort of thing. I think about a Christmassy one.

"But I also, sometimes when I'm daydreaming about it, I think, 'God, it would be really fun if Tanika went on a holiday, but the girls end up at the same resort, and then we have to solve something there.'

"If I say this enough out loud I'm hoping that I’ll sort of 'Derren Brown' Rob into sort of doing it.

"But I think we all have absolute daydreams about it. Like, I was talking to Phill [Langhorne] the other day, he plays Brendan, and he was saying he was hoping there might be an episode one day where Brendan's part of an amateur dramatics team in Marlow, and we get to sort of see him be a thesp'.

"So I think everybody has a weird daydream in their head of where they think this will go. Rob's got way better ideas than we have, so sadly he's not picking up on any of them. But I'm gonna keep ringing the bell, basically, of definitely being abroad. But yeah, a Christmassy one I'd love. I would really hope for that."

When will The Marlow Murder Club season 3 be released?

The Marlow Murder Club season 3 will start airing on U&Drama on Wednesday 18 March 2026, with the first two episodes airing back to back from 8pm.

This means the new season is arriving pretty much exactly a year after season 2 debuted, with that run having started airing on 19 March 2025.

Who will return to star in The Marlow Murder Club season 3?

Of course, it wouldn't be The Marlow Murder Club without the central quartet - that's Samantha Bond as Judith, Jo Martin as Suzie, Cara Horgan as Becks and Natalie Dew as Tanika.

Thankfully, all of them are returning, as are the rest of Tanika's team at the Marlow police, played by Tijan Sarr, Phill Langhorne and Holli Dempsey.

Meanwhile, one previous guest star who will be returning in an expanded role is Hugh Quarshie as Professor Gifford, who Samantha Bond has teased Judith is now in a "developing" romance with.

Of course, this season will also feature a host of new guest stars involved in each of the new cases, with Nigel Harman (EastEnders), Peter Davison (Doctor Who), Sarah Alexander (Art Detectives), Tony Gardner (Last Tango in Halifax), Harry Enfield (Miss Marple – The Moving Finger) and Cherie Lunghi (Strike) amongst them.
