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?
