Angus Thinnson MacDonald is finally supposed to shed some pounds: Karen Miller, his doctor and lady love, is relentless! A bit perplexed about this matter, he prefers to focus on his latest case. A young woman and her little daughter have gone missing. The trail leads to a cult that demands inhumane sacrifices from its members. Fearlessly, MacDonald investigates and even impersonates the Duke of Edinburgh, better known as Prince Philip, multiple times. But what does this case have to do with culinary arts?, he wonders. A lot, it slowly but surely turns out. Joining him again is Alberto Vitiello, the Italian guest house owner and his partner in crime, the Dottore Watson. Constantly at odds with his guests, he even suspects some of them. However, gourmet MacDonald remains skeptical.
