The Marlow Murder Club Returns for Season 4 on MASTERPIECE Mystery!

June 2, 2026 - Boston, MA: Much loved crime-drama The Marlow Murder Club is set to return for a fourth season with six new episodes on MASTERPIECE Mystery! on PBS.
The new season will feature an adaptation of best-selling author Robert Thorogood’s novel, Murder on the Marlow Belle, alongside brand-new original mysteries. Returning to solve more complex and intriguing murders in Marlow are meticulous crossword-setter Judith Potts (Samantha Bond); pillar of the community and vicar’s wife, Becks Starling (Cara Horgan); and no-nonsense dog walker Suzie Harris (Jo Martin). Working tirelessly alongside DI Tanika Malik (Natalie Dew) and her police team, our crime-solving trio puts their unconventional methods into practice to catch the killers in three new stories.
The Marlow Murder Club Season 4 begins with the discovery of a body in the river that is soon linked to the Marlow Amateur Dramatics Society and a homegrown Hollywood star. The team must also unravel the truth behind a man's sudden death at his mother’s wake. He appears to have died from an allergic reaction, but is there more to it than that? And when the co-owner of a vineyard is found dead, drowned in his own wine, the women work to make sense of this seemingly unmotivated murder. Can the amateur sleuths navigate the family scandals and personal betrayals to unmask the killers in their close-knit community?
Series regulars Holli Dempsey, Phill Langhorne and Tijan Sarr also return for the new season with filming set in Marlow and the surrounding area.
The Marlow Murder Club Season 4 will continue the show’s signature blend of humor, mystery and heart, from an exceptional team of writers. Episodes one and two will be written by Robert Thorogood and is an adaptation of his novel Murder on the Marlow Belle. The second two stories are original mysteries: Amy Reith will write episodes three and four, with Robert and Amy co-writing episodes five and six.
The Marlow Murder Club S4 has been commissioned by Susanne Simpson, head of scripted content for MASTERPIECE, with Claire Hookway as executive producer for UKTV.
Monumental Television’s Alison Owen and Debra Hayward say, “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.”
