Le mystere Daval

Jonathann Daval is worried about his wife Alexia Daval's disappearance. He alerts his parent-in-laws, Isabelle Fouillot and Jean-Pierre Fouillot, his sister-in-law Stephanie, as well as Stephanie's husband Gregory Gay. The investigation is led by Police Captain Dacost and Magali Paulin. Later, Alexia's body is found in a wooded area. She was strangled elsewhere and then dumped there. Suspicions fall on Jonathann. He initially confesses to the crime, but later claims that Gay killed her and that the rest of the family asked him to keep silent and to dump the body. The Fouillot family is shocked but succeeds in persuading Jonathann to tell the truth. He finally admits to the crime.
