Overview: On May 31, 1908, in a bourgeois house in the 15th arrondissement of Paris, Adolphe Steinheil, a famous painter, and his mother-in-law, Mrs. Japy, were murdered. The wife of the deceased, Marguerite Steinheil, is a woman of haunting beauty and a sulphurous reputation. Isn't it said that President Félix Faure died in his arms? Found tied up and gagged on a bed, she is the only survivor of the drama that took place that night. For the less romantic, his story does not convince the police at all.
