Diane, Crime Fighter - Alone in the world

A luxury villa, a long winter night and a family reunion that goes tragically wrong. In a matter of seconds, the Cotrel family is decimated: father, stepmother, uncle, aunt and family friend are all murdered. Fabien, the Cotrel son, who already lost his mother, finds himself again orphaned and... a suspect. His strange attitude, his lack of an alibi, his lies, and his shadowy nature designate him as the ideal culprit. Is it because he is 17, her own son's age, that Diane grows fond of him? Or because she is disconcerted by the new public prosecutor and because she loses all her bearings and professional reflexes? In any case, Henri Cotrel was far from being a simple man and his strong character earned him a lot of enmity. Yes, he was hard on his son, but not only that. His other brother, Daniel, would have a lot to say about that. The two siblings loathed one another. Daniel is thus also a suspect. But then Daniel is murdered. Fabien is alone, and more than ever a suspect.
