The series follows retired archeologist Judith Potts (played by Samantha Bond) who lives a fairly normal life until she witnesses a murder. The police don't believe her so she takes matters into her own hands.

Setting up what happens to Judith, Samantha Bond tells us: "Every evening she has a whisky and then swims in the Thames, which is relaxing for her. But one day, during her swim, she hears a gunshot, which inspires her to begin her informal investigation. She has a passion — as I do — for puzzles. And because of her archaeological background, she likes to delve! By the end of the first episode, you know what’s at stake and yet there are so many knots still to be untied, doors to be opened and mysteries to be solved…”

Speaking about the adaptation, writer Robert Thorogood said: "After over a decade of working on Death in Paradise, I’m thrilled to be creating a brand new murder mystery series for TV. I can’t wait for audiences to join Judith, Becks, and Suzie on their adventures as they solve a series of fiendishly puzzling murders."

The Marlow Murder Club plot

The official synopsis for The Marlow Murder Club is: "Judith Potts is seventy-seven years old and blissfully happy. She lives on her own in a faded mansion just outside Marlow, there's no man in her life to tell her what to do or how much whisky to drink, and to keep herself busy she sets crosswords for The Times newspaper."

"One evening, while out swimming in the Thames, Judith witnesses a brutal murder. The local police don't believe her story, so she decides to investigate for herself, and is soon joined in her quest by Suzie, a salt-of-the-earth dog-walker, and Becks, the prim and proper wife of the local Vicar."

"Together, they are the Marlow Murder Club. When another body turns up, they realise they have a real-life serial killer on their hands. And the puzzle they set out to solve has become a trap from which they might never escape..."
