The complete synopsis for series three of The Marlow Murder Club states: "Now an established part of newly promoted DI Tanika Malik's crime solving gang, retired archaeologist Judith Potts, dog walker Suzie Harris, and vicar's wife Becks Starling are back and bringing their unconventional methods to a string of high-profile murders.

"From the sudden death of the town's beloved mayor - the nicest man in Marlow - 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?"

Daniel Rusteau and Robert Thorogood co-authored episodes one and two of the fresh series, whilst Amy Reith crafted episodes three and four, with Julia Gilbert assuming responsibility for episodes five and six. The series is an adaptation of the book Queen of Poisons, written by Robert.

The third series of The Marlow Murder Club will consist of six one-hour episodes. This series is a joint venture with co-producer and US broadcaster MASTERPIECE, and is produced by Monumental Television in collaboration with ITV Studios.
