"Mariandel" now offers to make a statement in private, and retires behind a screen with the Police Inspector. Soon Ochs sees articles of women's clothing coming into view. He rages against the vice squad, but is interrupted by the arrival of the Marschallin. The Police Inspector greets her before clearing the room, and she explains to the Baron that he has been had. Sophie returns and tells Ochs that their engagement is off; Octavian emerges, and the Marschallin confirms that Octavian, Valzacchi, Annina, and others set up a "masquerade" together to break his engagement. Ochs, glancing back and forth between Octavian and the Marschallin, now grasps the nature of their relationship and implies that he may tell the Marschallin's husband of it, but he is cowed by the Marschallin's force of will (if not the sight of Octavian's sword) and ingloriously departs, pursued by children and bill collectors.
