For Madame Dubonnet, the owner of the small, cheap guesthouse whose clientele was composed almost completely of employees in a nearby Montmartre vaudeville theater, this second curious death in the same room had very unpleasant consequences. Already several of her guests had moved out, and other regular clients had not come back. She appealed for help to her personal friend, the inspector of police of the ninth precinct, who assured her that he would do everything in his power to help her. He pushed zealously ahead not only with the investigation into the grounds for the suicides of the two guests, but he also placed an officer in the mysterious room.
