MME. DUPONT [carelessly, to Courthezon, who has stopped] Go on. It’s only Caroline. [Interested] And you still won’t tell us what it is?
COURTHEZON. Not yet. [Rising, bowing to Caroline] Good day, Mlle. Caroline.
CAROLINE [half-returning his bow] Good day, M. Courthezon.
MME. DUPONT. I can imagine how pleased you are.
COURTHEZON. Of course I am.
CAROLINE. You have finished your invention!
COURTHEZON. Yes. How did you guess?
CAROLINE [a little confused] Oh, only—
COURTHEZON. Only?
