What begins as a holiday trip for amateur sleuth and cooking aficionado Sadie Hoffmiller and her daughter, Breanna, turns into a bizarre mystery. First comes the discovery of a dead body in the sitting room of an English manor belonging to the family of Breanna’s boyfriend, who is also heir to the family title.

When the body comes up missing, Sadie and Breanna are stranded at the estate until the police can clear them to leave. Armed with a jogging whistle, her personal recipe collection, and an unfailing sense of American justice, Sadie begins her own investigation to find the killer. But when she seems to encounter one dead end after another, Sadie wonders if anyone is telling the truth - or if the case is really as hopeless as it appears to be.
