Meet the world's most unusual undercover team... Working undercover for HM Revenue & Customs can be tough, 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. In this first case DJ Smith and Gorgonzola are on the trail of a drug-smuggling ring operating in and around Edinburgh. Beneath the innocent surface of the White Heather Hotel eddies a sinister undercurrent. One death follows another. Who among the cast of formidable and flamboyant guests specialises in making murder look like accident? As sea mists gather, a deadly game of cat and mouse is played as the killer awaits a chance to strike... An immensely readable and very funny foray into the dark and often dangerous world of undercover operations, told in the Mulgray Twins' own inimitable style.
