Deauville as setting in Simenon's popular fiction
up a private detective agency, L’Agence O, with his collaborator the photographer Emile. Torrence and Emile are in Deauville observing madame Davidson, the wife of a wealthy American, when Loulou, a flower seller at the casino, is murdered with a bullet from madame Davidson’s revolver. Shortly after, monsieur Henry, head porter at the hotel Royal, is discovered killed with a bullet from another weapon. Emile solves the case by immersing himself, in the manner of Maigret, in the life of the staff and clients of the Royal. It transpires that count Vatsi, a wealthy Hungarian guest at the hotel, had recognised Henry as a former rival in love and realised that madame Davidson and Loulou were the daughters of Henry and his (Vatsi’s) former fiancée. By the purest coincidence, all of the characters were in Deauville at the same time and Vatsi had killed Henry and Loulou using Madame Davidson’s stolen revolver in order to throw suspicion on her.
