Join Judith, Suzie, and Becks as they race against the clock to stop a killer in their tracks.

Join Judith, Suzie, and Becks in investigating a brutal murder. Along with Detective Tanika Malik, they must piece together clues, grill suspects, and face down real danger as they work against the clock to stop a killer in their tracks.

Retired archaeologist Judith Potts lives alone in the peaceful town of Marlow, filling her time setting crosswords for the local paper. During her regular evening swim in the River Thames, Judith hears a gunshot coming from her neighbor’s garden, and believes that a brutal murder has taken place. When the local police – led by newly promoted DS Tanika Malik - are reluctant to believe her story, Judith starts her own investigation, enlisting the help of unfulfilled vicar’s wife Becks Starling. When local dog walker and empty-nester Suzie Harris becomes personally involved in the case, she also joins Becks and Judith’s investigation. As the bodies begin to pile up, the unlikely group of sleuths must use all of their skills to piece together clues, grill suspects, and face down real dangers as they race against the clock to stop the killer in their tracks.
