At ten o'clock they rose from the table, and as the air was sweet and mild they walked about a while under the magnificent pine trees that shaded the house of Rosa Vanozza, while Caesar never for an instant let his brother out of his sight. At eleven o'clock the Duke of Gandia bade good-night to his mother. Caesar at once followed suit, alleging his desire to go to the Vatican to bid farewell to the pope, as he would not be able to fulfil this duty on the morrow, his departure being fixed at daybreak. This pretext was all the more plausible since the pope was in the habit of sitting up every night till two or three o'clock in the morning.
The two brothers went out together, mounted their horses, which were waiting for them at the door, and rode side by side as far as the Palazzo Borgia, the present home of Cardinal Ascanio Sforza, who had taken it as a gift from Alexander the night before his election to the papacy. There the Duke of Gandia separated from his brother, saying with a smile that he was not intending to go home, as he had several hours to spend first with a fair lady who was expecting him. Caesar replied that he was no doubt free to make any use he liked best of his opportunities, and wished him a very good night. The duke turned to the right, and Caesar to the left; but Caesar observed that the street the duke had taken led in the direction of the convent of San Sisto, where, as we said, Lucrezia was in retreat; his suspicions were confirmed by this observation, and he directed his horse's steps to the Vatican, found the pope, took his leave of him, and received his benediction.
From this moment all is wrapped in mystery and darkness, like that in which the terrible deed was done that we are now to relate.
The Duke of Gandia, when he quitted Caesar, sent away his servants, and in the company of one confidential valet alone pursued his course towards the Piazza della Giudecca. There he found the same man in a mask who had come to speak to him at supper, and forbidding his valet to follow any farther, he bade him wait on the piazza where they then stood, promising to be on his way back in two hours' time at latest, and to take him up as he passed. And at the appointed hour the duke reappeared, took leave this time of the man in the mask, and retraced his steps towards his palace. But scarcely had he turned the corner of the Jewish Ghetto, when four men on foot, led by a fifth who was on horseback, flung themselves upon him. Thinking they were thieves, or else that he was the victim of some mistake, the Duke of Gandia mentioned his name; but instead of the name checking the murderers' daggers, their strokes were redoubled, and the duke very soon fell dead, his valet dying beside him.
