Le trompeur trompé

Le trompeur trompé (The Trickster Tricked) is a one-act opéra comique by Pierre Gaveaux, to a libretto by François Bernard-Valville.

Duval, his clerk, is working at his desk, musing over the circumstances that brought him to this role: He is really a midshipman, but has taken on the role of clerk due to his love for Agathe, Jocard's pupil.

She cannot be forced to marry him, but should Jocard find out about Duval's scheme, trouble would arise.

("Il faut, il faut, que je vous quitte")[4] Jocard is heard approaching as they finish their farewells, and Agathe fails to escape in time.

The scene ends with Duval, shaken, asking Agathe if it is necessary for him to return, only for Jocard to overhear him, and, misconstruing him, cheerily tell him that yes, he will be needed afterwards.
