On the eve of the prestigious International Gastronomy Competition in Lyon, the dinner bringing together chefs from all over the world turns sour when one of them is mistakenly murdered. Tabata Blier de Sapeur, a three-time winner of the coveted title, finds herself at the centre of envy and suspicion. Desperate to evade the assassin, she enlists the help of two vibrant musicians to act as her camouflage. When the worlds of contemporary music collide with haute cuisine, unexpected twists await. And as secrets from the past resurface, a thrilling investigation ensues. It’s your chance to unravel the mystery and shed light on this dark affair!

Embark on a journey through Lyon’s hidden streets and charming locales, from the banks of the Rhône to the bustling City Hall.
