The popular crime-solving trio is back for another round of mysteries. The Marlow Murder Club Season 3 arrives on PBS this September, bringing with it a mix of returning favourites and new faces. The show, created by Death in Paradise writer Robert Thorogood, continues to draw viewers with its mix of lighthearted mystery and character-driven storytelling.
The series follows three amateur sleuths in the English town of Marlow who team up to solve murders that leave the local police scratching their heads. Season 3 picks up with the group now officially working alongside Detective Inspector Tanika Malik. The new season has already aired in the UK on U&Drama in March 2026 and is now set for its US debut.
Main Cast Returns for Season 3
The core trio remains unchanged, with all three leads coming back for the new season.
Samantha Bond returns as Judith Potts, the retired archaeologist and crossword writer who started the group after hearing a gunshot from her neighbour’s house. Bond is well known for playing Miss Moneypenny in the James Bond films, as well as roles in Downton Abbey and The Sarah Jane Adventures.
Jo Martin is back as Suzie Harris, the dog walker and single mother who got pulled into Judith’s investigations. Martin played the Fugitive Doctor in Doctor Who and has also appeared in Fleabag and Top Boy.
Cara Horgan reprises her role as Becks Starling, the vicar’s wife who struggled to fit into the community before finding her place with the crime-solving group. Horgan has appeared in PBS’ Grantchester and Netflix’s The Sandman.
Natalie Dew also returns as DI Tanika Malik, who has been promoted since the last season. She now leads the local investigations and officially works with the trio as part of her team.
Supporting Cast and Police Team
Several supporting actors are returning to fill out the police department and other recurring roles.
Phill Langhorne returns as DS Brendan Perry, part of DI Malik’s team. Langhorne is known for his work in Call the Midwife.
Tijan Sarr is back as DC Jason Kennedy. Sarr has appeared in Shadow and Bone.

Ella Kenion also returns as DCI Vicky Greenly.
Guest Stars Join the Cast
Season 3 brings an impressive list of guest stars across its six episodes. Each two-part episode features its own set of guest characters caught up in the murder cases.
Peter Davison appears as Geoffrey, the Mayor of Marlow, in the first two episodes. Davison is famous for playing the Fifth Doctor in Doctor Who.
Sarah Alexander plays Sophia Hollingbury in the opening episodes.
Nigel Harman joins as Marcus. Harman is known for his work on EastEnders.
Other guest stars appearing throughout the season include Harry Enfield, Alastair Mackenzie, Tony Gardner, Cherie Lunghi, Adrian Lukis, Jacqueline Boatswain, Jason Merrells, and Ranjit Krishnamma. Susan Lynch also appears in later episodes.
What to Expect in Season 3
The new season features three murder mysteries spread across six episodes, with each case taking two episodes to resolve.
Episode one and two, titled “The Queen of Poisons,” deal with the death of the town’s beloved mayor. Episode three and four, called “Murder in the Dark,” take the group to a university reunion at a manor house where Becks becomes a suspect. Episode five and six, “An Appetite for Murder,” involve a celebrity chef found dead at his cookbook launch.
The cases hit closer to home this season, with one mystery directly linked to Becks’ past. The team also faces the possibility that their roles as civilian advisors could be at risk.
Samantha Bond spoke about the scripts, saying the twists are “phenomenal” and that the ones in the third storyline are “colossal”.
“All the scripts have been amazing. And the twists are phenomenal but the ones in ‘An Appetite for Murder’ are colossal. I defy anyone to work them out.”
The season also includes personal storylines for the main characters. Suzie tries speed dating and trains for a new career, while Judith’s relationship with Professor Darius continues to develop.
