When a Customs and Revenues Officer on the brink of exposing a huge money-laundering outfit is murdered in Tenerife, there is only one team capable of ensuring Operation Canary Creeper's continuance and success. DJ Smith must use all of her cunning and experience to trap the devious Ambrose Vanheusen; her greatest asset, however, comes in the moth-eaten shape of 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 the prospective purchasers - some are innocently enjoying their holidays, but are others complicit in Vanheusen's schemes. Pompous writer Rudyard Scott, elderly Victoria Knight...something about Millie Prentice doesn't seem to add up, and Deborah is instantly antagonistic towards the arrogant Herbert G. Wainwright III...Disguises, cat-fights and narrow escapes make "Under Suspicion" a fast-paced and funny return to DJ and Gorgonzola on their follow-up mission to No Suspicious Circumstances.
