(J. Strauss II: Die Fledermaus). Ten. Husband of Rosalinde. He has committed a minor offence which carries a short prison sentence and is preparing to serve it. His friend Dr Falke collects him and they pretend to leave for the prison. In reality they go to Prince Orlofsky's ball. There Eisenstein, introduced as ‘Marquis Renard’ meets ‘Chevalier Chagrin’ and the two men converse in terrible French. He flirts with a masked Hungarian countess, not knowing it is his wife. Among the guests he recognizes Adele, his wife's maid. At 6 a.m. he leaves for the prison. On arrival he finds that ‘Chevalier Chagrin’ is Frank, the prison governor, and that his cell is already occupied—by his wife's singing‐teacher, Alfred. Rosalinde and Falke both arrive at the gaol and the confusion is sorted out. Created (1874) by Jani Szika.
