Retired archaeologist Judith Potts (Samantha Bond) lives alone in a faded mansion in the peaceful town of Marlow, filling her time by setting crosswords for the local paper.

During one of her regular wild swims in the Thames, Judith hears a gunshot coming from a neighbour’s garden and believes a brutal murder has taken place. When the police are reluctant to believe her story, Judith finds herself forming an unlikely friendship with local dog-walker and empty-nester Suzie Harris (Jo Martin) and vicar’s wife Becks Starling (Cara Horgan) as they start an investigation of their own. After solving their first murder, the three amateur sleuths are soon hired as civilian advisors by DI Tanika Malik (Natalie Dew) and become a regular part of her crime solving team.

Using each of their unique talents, the women must piece together clues, grill suspect witnesses, and face down real danger as they work to solve the crimes that come their way.
