Waterhouse, wrote the following: "Il segreto di Susanna owes its success partly to its disarming simplicity.

Lasting barely 45 minutes, with only two singing characters, it is conveniently cheap to produce; and the slender but distinctive idea of the libretto, combined with the elegant if rather miscellaneous charm of the music, has an obvious appeal which even subsequent cancer research has not seriously undermined.

"[1] While initially written in Italian, the premiere performance of Il segreto di Susanna was given in the German language using a translation by Max Kalbeck, at the Hoftheater in Munich on 4 December 1909.

[1] The most frequently performed of all of Wolf-Ferrari's works, the overture of the opera has become a well known concert piece.

Presented at the Met by Andreas Dippel's touring Philadelphia-Chicago Grand Opera Company, the production starred Carolina White as Susanna, Mario Sammarco as Count Gil and the Italian tenor Francesco Daddi in the silent role of Sante.

The room smells of tobacco, and he is surprised since he does not smoke and neither does Susanna, nor the servant, Sante.

As soon as he leaves the house, she closes the door and opens the small packet she gave to Sante when she came home.

Smelling the tobacco he starts to search the house for Susanna's lover on the pretext of looking for the umbrella he forgot.
