A mummified corpse has been found by workers who were knocking down a wall.Ariane Salles and Gaspard Lesage are in charge of the investigation.Recently the apartment was empty and the neighbors no have any notice about the last renters of the apartment.The forensic doctor , who is the father of Ariane (they haven't meet them since 20 years) , informs that the corpse is that one of a young woman who gave birth to a child.The question now is to find who has lived in that apartment and when exactly : so that they can investigate any birth registration and find the relation between the dead woman and the child.On the other side the apartment belongs to a brother and a sister because of an inheritance.The sister is married with an important man in Le Havre: in a first time they are reluctant to give notice about the renters of the apartment.
