The Marlow Murder Club Season 2 is set to return the fans to the quiet riverside town of Marlow with six new episodes. Season 2 will keep the show's low-key, clue-first style while following three murder mysteries. The plot will move at a steady pace and the solutions will come from logic and conversations, not spectacle.
The Marlow Murder Club Season 2 began its UK run in March 2025 but will reach American viewers on PBS on 24 August, 2025. Across the six episodes, the show will mix one story adapted from Robert Thorogood’s book with two original teleplays written for TV.
The setting, a real town in Buckinghamshire, stays central to the stories and is used to build mood and practical clues. If you liked the first season for its puzzle-driven mysteries, this season will keep that same approach without trying to be a darker crime drama.
Release date and where to watch The Marlow Murder Club Season 2

In the United States, The Marlow Murder Club Season 2 will start airing on Sundays beginning 24 August, 2025 at 9/8c on PBS and local PBS stations and apps. Online streaming can be done on Masterpiece on PBS.
Episode structure and story approach

The Marlow Murder Club Season 2 will run to six episodes presented as three two-part mysteries, so each case unfolds over two episodes rather than one. The opening case adapts Thorogood’s second book, while the other two stories were written for television by the show’s screenplay team.
The plots will focus on everyday places: a study, a cul-de-sac, and a sailing club, and will use small, explainable clues to move the pieces into place. This structure will keep the storytelling calm and logical rather than fast or sensational.
Cast and notable guest stars

The main trio return in their roles, including Samantha Bond as Judith Potts, Jo Martin as Suzie Harris, and Cara Horgan as Becks Starling, alongside Natalie Dew in a senior police role. Several members of the supporting police team also come back.
The season adds guest performers such as Samantha Womack, Patrick Robinson, and other well-known British actors. The mix of regulars and guest cast gives each mystery a fresh set of motives and local tensions to explore.
Filming locations and the show’s feel

The production uses real streets and landmarks in Marlow, Buckinghamshire, to create an authentic small-town look. Local sites like the river, the high street, and the suspension bridge appear in scenes and help the viewer place where clues are found.
That real setting supports the show’s quiet tone and makes small details, a shop display or a boat, feel important to the plot. The visual style, therefore, matches the measured pace of the stories.
What to expect from Season 2
Viewers who like character work, dialogue, and steady clue gathering will find the season similar in spirit to the first. If you prefer faster, darker police dramas; this show will feel different. The Marlow Murder Club Season 2 will keep the same calm, puzzle-first approach while adding new guest players and three neat cases across six episodes.
