A celebrated dramatist and his collaborator engineer a theatrical ruse to resolve romantic entanglements involving a young composer, a prima donna and a jealous actor. By mounting a play-within-the-play in a seaside castle they use rehearsals, mistaken identities and contrived scenes to expose loyalties and provoke comic misunderstandings. The three-act structure compresses much of the action into a single night and the following day, blending brisk farce with witty commentary on stagecraft. Themes examine the porous boundary between performance and reality and show how theatrical artifice can manipulate feeling while illuminating character.
