The Duke
So he has already found her out!

The Marquis (to his father)
My mother is deceiving us.

The Duchesse de Montsorel (to Joseph)
I am not at home.

The Duke
If you have asked Monsieur de Frescas to come why do you begin by
treating so great a personage with discourtesy? (To Joseph, despite a
gesture of protest from the Duchesse de Montsorel) Show him in! (To
the marquis) Try to be calm and sensible.

The Duchesse de Montsorel (aside)
In trying to help, I have hurt him, I fear.

Joseph
M. Raoul de Frescas.

Raoul (entering)
My eagerness to obey your commands will prove to you, Madame la
Duchesse, how proud I am of your notice, and how anxious to deserve
it.

The Duchesse de Montsorel
I thank you, sir, for your promptitude. (Aside) But it may prove fatal
to you.
