orologio en CB01 OFFICIAL. Adultery and a taste for the sweet life are the themes of the operetta Die Fledermaus. The wealthy rentier von Eisenstein sneaks off to a ball hosted by Russian Prince Orlofsky in the vain hope that his libertine manners will bring him closer to the beautiful women in attendance. His wife Rosalinde is similarly on shaky ground. She is having a secret affair with the singing teacher Alfred, who is mistaken for the cuckold and taken away to serve von Eisenstein's prison sentence.
