Amateur detective Mrs Devine tires of her jet-setting lifestyle and decides to spend the summer in the quaint English village of St Dodsbury on the Sodd. She is accompanied by her faithful chauffeur Coombs.
Mrs Devine is soon bored with the quiet life and sets out to become queen of St Dodsbury's social scene. Her plans are interrupted when a body is discovered in the tombola at the church Bring and Buy. Mrs Devine reluctantly sets out to investigate only to discover that St Dodsbury already has a resident sleuth - elderly spinster Miss Acres. And Miss Acres has no intention of being usurped by some interloper.
While the women systematically work their way through the suspects, the policeman officially in charge of the investigation, Inspector Tiny, concentrates on looking busy for his superiors and hoping the two women will kill each other.
As the body count rises, which of the ladies will unmask the killer? And will the village ever be the same again?
