Nurse Kate Palmer has only been living in Lower Tinworthy, a beautiful little village by the sparkling Cornish sea, for a short time but she’s already making a name for herself as the local Miss Marple. Although not everyone is keen on her recent investigations, least of all the new Detective Inspector Bill Robson.

When a body is found at her sister Angie’s newly purchased tea rooms, Kate is at first reluctant to get caught up in another mystery. But the murder is uncomfortably close to home and there’s gossip suggesting Angie and her latest boyfriend are somehow involved.

Determined to find justice for the deceased man and to protect her sister’s reputation, Kate recruits her close friend retired Detective Inspector ‘Woody’ Forrest. His knowledge of the local seaside villages will help her to come up with a list of potential names for the victim… and the murderer.

As they narrow down the possibilities, one of Kate’s patients, Mark Edderley, reveals a connection to her prime suspect. Days later, he dies in a suspicious boating accident. Kate is certain the murderer has struck again! But just as she’s about to solve the puzzle, Angie goes missing. Can she get to her sister before it’s too late?
