The idyllic riverside town of Marlow, Buckinghamshire, has never been so deadly—or so addictive. The hit British cosy crime series The Marlow Murder Club is officially back for a third season, and the stakes have never been higher. After Season 2 wrapped its run on PBS Masterpiece in the U.S. in late September 2025, PBS and UKTV (U&Drama) confirmed the renewal, with filming fully completed by late 2025. The six new episodes are slated to premiere in 2026, promising three fresh, fiendishly clever murder mysteries that plunge Judith Potts, Suzie Harris, and Becks Starling deeper into chaos than ever before.
Adapted from Robert Thorogood’s bestselling novels (the creator of Death in Paradise), The Marlow Murder Club blends light-hearted whodunit charm with genuine emotional depth. The show follows three unlikely friends who form an amateur sleuthing club in their seemingly peaceful English village. What begins as casual curiosity after witnessing (or stumbling upon) murders quickly turns into a full-fledged detective trio solving crimes the police can’t—or won’t—crack.
Samantha Bond returns as the sharp-witted, crossword-puzzle-obsessed retired archaeologist Judith Potts, the group’s unofficial leader whose keen mind and unflappable calm hide a steely resolve. Jo Martin reprises Suzie Harris, the bold, no-nonsense dog-walker and local entrepreneur whose street smarts and fearlessness make her the perfect counterbalance. Cara Horgan is back as Becks Starling, the vicar’s wife whose quiet demeanor masks a fierce moral compass and growing confidence in their investigations. The chemistry between the three women—witty banter, mutual support, and the occasional exasperation—remains the show’s beating heart, making every episode feel like catching up with old friends.
Natalie Dew continues as DS Tanika Malik, the professional detective who reluctantly (but increasingly) respects the trio’s instincts, even as she warns them to stay out of danger. The ensemble has become a fan favorite for its authentic portrayal of female friendship across generations and backgrounds, with each character bringing unique strengths to the table.
Season 3 ups the ante dramatically. While previous seasons featured standalone mysteries tied to the town’s eccentric residents, the new run dives “headfirst into chaos” with cases that hit closer to home. The three murders unfold across six episodes (each mystery spanning two parts), blending classic cosy crime tropes with darker, more personal stakes. Expect secrets from the women’s pasts to surface, alliances tested, and the idyllic Marlow facade cracking under pressure. Guest stars add star power and intrigue: Harry Enfield, Nigel Harman, Peter Davison, Sarah Alexander, Alistair MacKenzie, and others join the cast, bringing fresh suspects, victims, and red herrings to the riverside town.
The series excels in atmosphere: Marlow’s picturesque riverside paths, quaint cottages, and genteel community events provide the perfect contrast to the brutal crimes beneath the surface. The tone strikes a delicate balance—light-hearted and humorous in the sleuthing scenes, but unflinching when confronting motive, grief, and human frailty. Thorogood’s scripts deliver clever twists, satisfying reveals, and laugh-out-loud moments without sacrificing tension or emotional weight.
Fans have praised the show as “cozy crime at its best”—think Midsomer Murders meets Only Murders in the Building with a distinctly British wit and warmth. The ensemble’s camaraderie, the charming setting, and the satisfying puzzle-solving make it perfect for Sunday-night viewing or binge-watching. Yet Season 3 promises to push boundaries: trouble is “bigger, darker, and closer to home than ever,” hinting at threats to the trio’s safety, relationships, and the very community they protect.
With filming wrapped and post-production underway, anticipation is building. PBS Masterpiece will air Season 3 in the U.S. in 2026 (exact date TBD), following its UK run on U&Drama. Seasons 1 and 2 remain available for streaming on PBS Passport and other platforms, allowing new viewers to catch up on the murders, friendships, and gin-fueled detective work that have made The Marlow Murder Club a beloved hit.
The quiet little town of Marlow is about to get loud again—and audiences couldn’t be more excited. Judith, Suzie, and Becks are back on the case, and whatever darkness lurks beneath the surface this time, they’re ready to face it together. In a world of grim procedurals, The Marlow Murder Club Season 3 reminds us that cosy crime can still pack an emotional punch while delivering pure escapist joy. Mark your calendars for 2026—this murder club is far from finished.
