Four Dead Chefs - MJ Ritchie

Four celebrity chefs compete for the title of the best cook in Britain. The competition is run by the sinister and exploitative Bastien Baudelaire, who is discovered stabbed to death during the event. Only the competing chefs could have murdered him.
As one of the four restaurant critics judging the competition, Antonia persuades her fellow judges to join her in investigating Bastien's murder. They unearth a trail of dangerous liaisons, broken relationships, and the story of a curse on the competition. Chefs previously involved in this competition have also died. All four celebrity chefs have secrets to hide, and the judges soon discover that uncovering these secrets is a dangerous business.
