"Why did you not make the trial before you married?"

"Was it for me to propose such a thing? How should I suppose that such a
fine man was impotent? But I will tell you how it all happened. As you
know, I was a dancer at the Comedie Italienne, and I was the mistress of
M. de Sauci, the ecclesiastical commissioner. He brought your brother to
my house, I liked him, and before long I saw that he loved me. My lover
advised me that it was an opportunity for getting married and making my
fortune. With this idea I conceived the plan of not granting him any
favours. He used to come and see me in the morning, and often found me in
bed; we talked together, and his passions seemed to be aroused, but it
all ended in kissing. On my part, I was waiting for a formal declaration
and a proposal of marriage. At that period, M. de Sauci settled an
annuity of a thousand crowns on me on the condition that I left the
stage.

"In the spring M. de Sauci invited your brother to spend a month in his
country house. I was of the party, but for propriety's sake it was agreed
that I should pass as your brother's wife. Casanova enjoyed the idea,
looking upon it as a jest, and not thinking of the consequences. I was
therefore introduced as his wife to my lover's family, as also to his
relations, who were judges, officers, and men about town, and to their
wives, who were all women of fashion. Your brother was in high glee that
to play our parts properly we were obliged to sleep together. For my
part, I was far from disliking the idea, or at all events I looked upon
it as a short cut to the marriage I desired.

"But how can I tell you? Though tender and affectionate in everything,
your brother slept with me for a month without our attaining what seemed
the natural result under the circumstances."
