Following a string of disastrous house-sitting assignments, and an equally troubled personal life, Thea Osborne is understandably apprehensive about her latest commission: a wintry month in an isolated house with only an assortment of animals, including her loyal spaniel Hepzie, for company. With the summer lushness of the Cotswolds turned icy grey, Thea spends her first few days exploring the beautiful hamlet of Hampnett, meeting some of the locals.
