On the day Juno Browne's van goes up in flames and nearly cooks a dog, Juno meets James Westershall, owner of Moorworthy Chase, a large family estate. She is invited, along with her friends from Old Nick's, to bring along their goods for sale to an upcoming garden fete. Included in the invitation is the newest and most irritating member of the Old Nick's team, Gavin. During the fete Gavin wanders off and is later discovered dead in nearby woods, apparently the victim of a bizarre accident. A police investigation ensues, but results are inconclusive and Juno has a theory of her own. As she begins to investigate, she discovers that Gavin's is not the only strange death to have occurred at Moorworthy Chase, including that of an expert, researching colonies of rare bats in caves on the Moorworthy Estate. It soon becomes clear to Juno that there is something very wrong at Moorworthy and the caves contain a dark and dangerous secret.
