La Tosca, Drame en Cinq Actes

According to Wikipedia: "La Tosca is a five-act drama by the 19th-century French playwright Victorien Sardou. It was first performed on 24 November 1887 at the Théatre de la Porte Saint-Martin in Paris, with Sarah Bernhardt in the title role. Despite negative reviews from the Paris critics at the opening night, it became one of Sardou's most successful plays and was toured by Bernhardt throughout the world in the years following its premiere. The play itself is no longer performed, but its operatic adaptation, Giacomo Puccini's Tosca, has achieved enduring popularity. There have been several other adaptations of the play including two for the Japanese theatre and an English burlesque, Tra-La-La Tosca (all of which premiered in the 1890s) as well as several film versions."
