Fans of cozy British mysteries, rejoice: one of the genre's most beloved series is officially coming back for more. The Marlow Murder Club, starring former James Bond actress Samantha Bond, has been renewed for a fourth season on PBS Masterpiece. The announcement comes after the show's third season earned strong reviews in the UK, where it aired earlier this year.
The series follows three amateur sleuths—Judith Potts (Bond), Suzie Harris (Jo Martin), and Becks Starling (Cara Horgan)—as they solve murders in the picturesque English town of Marlow. For three seasons and 16 episodes, the trio has charmed audiences with their wit, intelligence, and unbreakable friendship. Season 4 will consist of six episodes, adapting one of Robert Thorogood's novels before moving to original mysteries.
What to Expect in Season 4
The new season kicks off with the discovery of a body in the river, linked to the Marlow Amateur Dramatics Society and a homegrown Hollywood star. The team will also investigate a man's sudden death at his mother's wake—seemingly from an allergic reaction—and the drowning of a vineyard co-owner in his own wine. As always, the women must navigate family scandals and personal betrayals to unmask the killers in their close-knit community.
Executive producers Alison Owen and Debra Hayward of Monumental Television expressed their excitement: “We’re delighted to be back in Marlow for a fourth time, bringing three more murder mysteries to one of the most picturesque towns in England. Robert and Amy have expertly crafted yet another deliciously twisty set of crimes to be solved. Packed with intrigue, wit and heart, we can’t wait to bring these new adventures to the screen.”
Cast and Production Details
All three leads—Bond, Martin, and Horgan—will return, along with Natalie Dew as DI Tanika Malik. Holli Dempsey, Phill Langhorne, and Tijan Sarr are also set to reprise their roles. Production is about to begin in and around Marlow, with the season expected to premiere on PBS Masterpiece in the U.S. on Sunday, September 6, 2026.
For fans of British television, this renewal is just one of many exciting updates. Meanwhile, other beloved series like Law & Order: SVU and the One Chicago trio are also returning this fall. And if you're in the mood for more mystery, the next Harry Bosch novel is getting a TV adaptation soon.
A Cozy Mystery Done Right
The Marlow Murder Club has carved out a loyal following by blending classic whodunit puzzles with the charm of the British countryside. It joins the ranks of fan favorites like The Thursday Murder Club and Midsomer Murders, proving that audiences never tire of clever mysteries solved by unlikely heroes. With Season 4 on the way, there's plenty more intrigue in store.
