The basic idea of a Revenue & Customs agent with an assistant 'sniffer-cat' (with attitude) is an amusing concept. Regretfully the writing just doesn't come up to scratch. The authors of this series (of which this is number two) are identical twins, Helen and Morna Mulgray and one wonders who wrote what in these rather pedestrian stories. The cat,Gorgonzola,is the best character,but appears too seldom. On the other hand the agent D.J. Smith is a cypher,with no outstanding features at all. Tenerife is the setting for the story,which concerns money-laundering and a most uninteresting villain. ( )
