Revisiting the heart of Marlow while expanding its world through new characters

The Marlow Murder Club Season 3 has finished filming and will once again follow Judith Potts, Suzie Harris, and Becks Starling as they continue their unlikely crime-solving adventures. Samantha Bond, Jo Martin, and Cara Horgan reprise their roles, along with Natalie Dew as DI Tanika Malik.

This time, their dynamic is set against an even bigger canvas, with the series introducing three distinct murder cases spread across six episodes.

What makes this season particularly exciting is the addition of a remarkable set of guest stars. Nigel Harman, Peter Davison, Jacqueline Boatswain, Sarah Alexander, Tony Gardner, and Jason Merrells are all set to appear in the opening two episodes, which were cowritten by Daniel Rusteau and Robert Thorogood.

For episodes three and four, written by Amy Reith, the show welcomes comedy veteran Harry Enfield. Rounding out the season, episodes five and six are written by Julia Gilbert and will feature Cherie Lunghi, Adrian Lukis, and Alastair Mackenzie.

The returning cast will also see Hugh Quarshie back as Professor Darius Gifford, alongside familiar faces Phill Langhorne, Holli Dempsey, and Tijan Sarr as part of Tanika's police team.

Narrative evolution and what the first look tells us about tone and direction for The Marlow Murder Club Season 3

Beyond the cast announcements, the first look images for The Marlow Murder Club Season 3 hint at the shift waiting for fans. These glimpses suggest a season rooted in community tension, as the new synopsis makes clear:

"From the sudden death of the town's beloved mayor – the nicest man in Marlow – to a celebrity chef found dead at the launch of his cookbook with half the town in attendance, the team will be working under the watchful eye of the Marlow community. They'll also be called to action at a university reunion in an eerie manor house where in a surprising twist, Becks finds herself amongst the suspects. Could this case threaten our amateur sleuths’ roles as civilian advisors?"

The synopsis teases three standout mysteries. One involves the sudden death of Marlow's beloved mayor, described as "the nicest man in town."

Another case unfolds at a star-studded cookbook launch where a celebrity chef is shockingly found dead in front of half the town.

In a particularly intriguing storyline, Becks is pulled into a university reunion at a country house, but only this time, she's among the suspects. Each mystery expands the scale of the series, making the sleuths more entangled in the very community they serve.

Speaking about The Marlow Murder Club Season 3, Claire Hookway, commissioning executive for UKTV, said:

"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."
