Giovanna Matthews has an acceptable life in London with her own flat, a good job, and recent engagement to the son of a Scottish landowner. But not long after her engagement to Alan, news of Aunt Grace's death hits Giovanna like a red double decker bus. Ignoring Alan's pleas to stay, she bundles her dog and suitcase into a rusty Volkswagen and drives to Aunt Grace's cottage on the Cornish coast where Giovanna had spent childhood summers with her cousin. Putting her aunt's affairs in order is further complicated when Giovanna discovers the local constabulary has its own view on Aunt Grace's demise - A view that Giovanna vows to challenge. Unless she can discover how her aunt died and find her missing cousin quickly, she stands to lose both her inheritance and Alan.
