Commissaire Georges Dupin is certain these first beautiful summer days in June would be perfect for a fun trip to Saint-Malo. In a region known as the culinary heart of Brittany, the paradoxical city is known for being a uniquely Breton, yet un-Breton, place. Their cuisines moto is voyages et aventures. Travel and adventure. Dupin would love to explore the internationally renowned cuisine one bite at a time. But to his chagrin, Dupin is there instead to attend a police seminar dedicated to closer collaboration between the Breton departements. To prepare himself for whats to come while in Saint-Malo, Dupin wanders through the halls of a local market - stopping to sample its wares as he goes - while admiring its aromatic orchestra. But Dupins morning is derailed when theres a murder at a nearby stall. He quickly realises this case is unlike any hes worked on before. The police know the victim: Blanche Trouin, a grand chef of the region. They know the perpetrator: Lucille Trouin, Blanches sister and fellow successful chef in the area. The two had a well-known and public feud. After a bit of searching, Lucille is even in custody. The only thing theyre missing is the motive. And Lucille refuses to talk. Saint-Malo doesnt want any help from the visiting commissaires. Even Dupins assistant, Nolwenn, is telling him to stay out of it. But Dupin, along with a few of his Breton colleagues, cant help but begin an investigation into why a chef killed her sister in the middle of a crowded market.
