内容简介：
It can be tough working undercover for HM Revenue and Customs, but DJ Smith has more than a little help from her trained sniffer cat, Gorgonzola, a moth-eaten Persian with gourmet tastes and a mind of her own. This first investigation finds DJ and Gorgonzola on the trail of a heroin smuggling ring operation in and around Edinburgh. Their first port of call is the White Heather Hotel, owned by the formidable Morag Mackenzie. Beneath the innocent surface of the country house hotel eddies a sinister undercurrent. One death follows another. As sea mists gather, a deadly game of cat and mouse is played - but who will survive to fight another day?
