The Chester Square Cookery School in the heart of London offers students a refined setting in which to master the fine art of choux pastry and hone their hollandaise. True, the ornate mansion doesn’t quite sparkle the way it used to—a feeling chef Paul Delamare is familiar with these days. Worn out and newly broke, he’d be tempted to turn down the request to fill in as teacher for a week-long residential course, if anyone other than Christian Wagner were asking.

Christian is one of Paul’s oldest friends, as well as the former recipient of two Michelin stars and host of Pass the Gravy! Thanks to a broken arm, he’s unable to teach the upcoming session himself, and recruits Paul as stand-in. The students are a motley crew, most of whom seem more interested in ogling the surroundings (including handsome Christian) than learning the best ways to temper chocolate.

Yet despite his misgivings, Paul starts to enjoy imparting his extensive knowledge to the recruits—until someone turns up dead, murdered with a cleaver Paul used earlier that day to prep a pair of squabs. Did one of his students take the lesson on knife techniques too much to heart, or was this the result of a long-simmering grudge? In between clearing his own name and teaching his class how to perfectly poach a chicken, he’ll have to figure out who’s the killer, and avoid being the next one to get butchered . . .
