“All this is very strange, but I have promised passive obedience, and I will come down with two lights. May I hope that you will explain this riddle to me at your next interview?”

“By to-morrow, at latest, you shall know the whole story.”

“My curiosity will prevent me from sleeping.”

“Not so, dear heart; sleep peacefully, and be sure of my gratitude.”

The reader will think that after this conversation my heart was perfectly at rest; but how far was I from resting! I returned to Venice, tortured lest I should be told in the evening at the door of the cathedral, where we were to meet, that the nun had been obliged to put off her appointment. If that had happened, I should not have exactly suspected M—— M——, but the ambassador would have thought that I had caused the scheme to miscarry. It is certain that in that case I should not have taken my man to the parlour, but should have gone there sadly by myself.

I passed the whole day in these torments, thinking it would never come to an end, and in the evening I put a letter in my pocket, and went to my post at the hour agreed upon.

Fortunately, Murray kept the appointment exactly.

“Is the nun there?” said I, as soon as he was near me.

“Yes, my dear fellow. We will go, if you like, to the parlour; but you will find that we shall be told she is ill or engaged. If you like, the bet shall be off.”

“God forbid, my dear fellow! I cling to that hundred ducats. Let us be gone.”
