When a Customs and Revenues Officer on the brink of exposing a huge money-laundering outfit is murdered in Tenerife, DJ Smith must use all of her cunning and experience to trap the devious Ambrose Vanheusen. Her greatest asset is her Persian cat Gorgonzola, since Vanheusen's one weakness is his love of the breed. Going undercover as a PA for Vanheusen's company, Exclusive, retailer of luxury homes and suspected front for darker purposes, DJ is in charge of organising excursions for prospective purchasers. Some are innocently enjoying their holidays, but are others complicit in Vanheusen's schemes?
