None of these explanations satisfied me. When evening came I walked slowly past the house of Lucrezia, but I did not see anything. I went up and down past it with no further result. Three or four evenings followed, and I danced attendance under her windows as I went home from the Aldobrandi palace, with ever the same want of success. I had begun to forget the mysterious occupant of No. 13, when, passing towards midnight through the lane, I distinctly heard a woman's light laugh behind the shutter of the window at which the giver of the flowers had appeared to me. Twice I heard that little laugh, and I could not prevent feeling slightly afraid, when just at that moment I saw come out at the other end of the street a group of penitents, closely hooded, with tapers in hand, bearing a corpse to burial. When they had gone by I took up my stand once more under the window; but this time I did not hear anything. I tried to throw pebbles; and I even called out more or less loudly; but still no one appeared; and, a heavy shower coming on, I was obliged to beat a retreat.

I am ashamed to tell how many times I stood before that accursed house without succeeding in solving the riddle that tormented me. Once only did I pass along the Viccolo di Madama Lucrezia with Don Ottavio and his ubiquitous Abbé.

"That is the house of Lucrezia," I said.

I saw him change colour.

"Yes," he replied; "a very dubious popular tradition asserts that Lucrezia Borgia's little house was here. If those walls could speak, what horrors they could reveal to us! Nevertheless, my friend, when I compare those times with our own I am seized with regrets. Under Alexander VI. there were still Romans. Now there are none. Cæsar Borgia was a monster; but he was a great man. He tried to turn the barbarians out of Italy; and perhaps, if his father had lived, he might have accomplished his great design. Oh! if only Heaven would send us a tyrant like Borgia to deliver us from these human despots who are degrading us!"

When Don Ottavio threw himself into the realms of politics, it was impossible to stop him. We were at the Piazza del Popolo before his panegyric in favour of enlightened despotism was concluded; but we were a thousand miles from the subject of my Lucrezia.

One night, when I was very late in paying my respects to the Marquise, she told me her son was unwell, and begged me to go up to his room. I found him lying on his bed, still dressed, reading a French journal which I had sent him that morning concealed between the leaves of a volume of the Fathers. An edition of the Holy Fathers had for some time served us for those communications which he had to conceal from the Abbé and the Marquise. On the day when the Courier de France appeared I received a folio Father. I returned another, in which I slipped a newspaper, lent me by the Ambassador's secretary. This gave the Marquise an exalted notion of my piety; and also his director, who often wanted to make me discuss theology with him.

When I had talked for some time with Don Ottavio, and had noticed that he seemed so much upset that not even politics could attract his attention, I recommended him to undress, and I bid him adieu. It was cold, and I had no coat with me; Don Ottavio pressed me to take his, and in accepting it I received a lesson in the difficult art of wearing a cloak in the proper Roman fashion.

I left the Aldobrandi palace muffled up to the eyes. I had gone but few steps on the pavement of the Square of Saint-Mark when a peasant, whom I had noticed seated on a bench by the gate of the palace, came up to me and held out a crumpled bit of paper.

"Read it, for the love of God!" he said, and quickly disappeared, running at top speed.
