The cardinal, delighted at this increase of favour, did not miss his appointment.

So, in the morning, he started an horseback for the Vatican; but at a turn of the first street he met the governor of Rome with a detachment of cavalry, who congratulated himself on the happy chance that they were taking the same road, and accompanied him to the threshold of the Vatican.

There the cardinal dismounted, and began to ascend the stairs; scarcely, however, had he reached the first landing before his mules and carriages were seized and shut in the palace stables.

When he entered the hall of the Perropont, he found that he and all his suite were surrounded by armed men, who led him into another apartment, called the Vicar's Hall, where he found the Abbate Alviano, the protonotary Orsino, Jacopo Santa Croce, and Rinaldo Orsino, who were all prisoners like himself; at the same time the governor received orders to seize the castle of Monte Giardino, which belonged to the Orsini, and take away all the jewels, all the hangings, all the furniture, and all the silver that he might find.
The governor carried out his orders conscientiously, and brought to the Vatican everything he seized, down to the cardinal's account-book.

On consulting this book, the pope found out two things: first, that a sum of 2000 ducats was due to the cardinal, no debtor's name being mentioned; secondly, that the cardinal had bought three months before, for 1500 Roman crowns, a magnificent pearl which could not be found among the objects belonging to him: on which Alexander ordered that from that very moment until the negligence in the cardinal's accounts was repaired, the men who were in the habit of bringing him food twice a day on behalf of his mother should not be admitted into the Castle Sant' Angelo.
