The heavenly archipelago of Les Saintes. The body of Caroline Boissaux, owner of the Hotel Torment d'Amour, is found at the bottom of a cliff. Like the legend of Caroline: a Saintoise in love with the Chevalier de Fréminville who, out of amorous spite, threw herself from the same cliff 200 years earlier. Captain Gaëlle Boissaux's investigation takes a personal turn when her childhood sweetheart, Ludovic Augustin, is sent to the island to support her. And the investigators are not at the end of their surprises: in addition to a romantic investigation that resonates with their past history, they must apprehend a ghost who is terrorizing the population. Some say it would be the ghost of Caroline.
