Following two successful series, The Marlow Murder Club is coming back for a third run. 

Created by Robert Thorogood (Death in Paradise) and based on his novels, the show follows an unlikely group of women who form a club to help solve local murders.

The show stars Samantha Bond (Downtown Abbey), Jo Martin (Doctor Who), Cara Horgan (Alex Rider) and Natalie Dew (The Capture).

The series also features Holli Dempsey (Harlots), Phill Langhorne and Tijan Sarr.

Here’s what U&Drama have to say about The Marlow Murder Club series 3:

Now an established part of newly promoted DI Tanika Malik’s (Natalie Dew) crime solving team, retired archaeologist Judith Potts (Samantha Bond), dog walker Suzie Harris (Jo Martin) and vicar’s wife Becks Starling (Cara Horgan) are back and bringing their unconventional methods to a string of high-profile murders.

From the sudden death of the nicest man in Marlow, the town’s beloved Mayor, to a celebrity chef found dead at the launch of his cookbook with half the town in attendance, the team will be working under the watchful eye of the Marlow community. They’ll also be called to action at a university reunion in an eerie manor house where in a surprising twist, Becks finds herself amongst the suspects. Could this case threaten our amateur sleuths’ roles as civilian advisors?

The season will again follow the pattern of three two-part tales. The first is co-written by Daniel Rusteau and Robert Thorogood, adapting the latter’s novel Queen of Poisons. Then, Amy Reith (Then You Run) writes episodes three and four, while Julia Gilbert (Ridley) writes episodes five and six.

The show comes from Monumental Television in association with ITV Studios. It’s co-commissioned and co-produced by US broadcaster MASTERPIECE.

The Marlow Murder Club Series 3 will be available on U and U&DRAMA in 2026. In the UK, you can stream the first two series on U.
