“Signor, I recognise you,” replied the Grand Duke. “Let the room be cleared—I must speak with this gentleman alone.”

When the company had quitted the saloon, I entered into a minute detail of the events of the evening, to which his Highness paid the greatest attention; and when I had finished, the whole mystery was unravelled to me by him, and with which I will now satisfy the curiosity of my readers.

The Grand Duke had one daughter, by name Viola, whom he had wished to marry to Rodolph, Count of Istria; but Viola had met with Albert, Marquis of Salerno, and a mutual attachment had ensued. Although the Grand Duke would not force his daughter’s wishes and oblige her to marry Count Rodolph, at the same time he would not consent to her espousals with the Marquis Albert. Count Rodolph had discovered the intimacy between Viola and the Marquis of Salerno, and had made more than one unsuccessful attempt to get rid of his rival by assassination. After some time, a private marriage with the marquis had been consented to by Viola; and a year afterwards the Lady Viola retired to the country, and without the knowledge, or even suspicions, of her father, had given birth to a male child, which had been passed off as the offspring of one of the ladies of the court who was married, and to whom the secret had been confided.

At this period the secret societies, especially the Carbonari, had become formidable in Italy, and all the crowned heads and reigning princes were using every exertion to suppress them. Count Rodolph was at the head of these societies, having joined them to increase his power, and to have at his disposal the means of getting rid of his rival. Of this the Marquis of Salerno had received intimation, and for some time had been trying to obtain proof against the count; for he knew that if once it was proved, Count Rodolph would never be again permitted to appear in the state of Lucca. On the other hand, Count Rodolph had been making every arrangement to get rid of his rival, and had determined that it should be effected at this masquerade.

The Marquis of Salerno had notice given him of this intention, and also had on that morning obtained the proof against Count Rodolph, which he was now determined to forward to the Grand Duke; but, aware that his assassination by the Carbonari was to be attempted, and also that the wrath of the Grand Duke would be excessive when he was informed of their private marriage, he resolved to fly with his wife to Pisa, trusting that the proofs of Count Rodolph being connected with the Carbonari, and a little time, would soften down the Grand Duke’s anger. The marquis had arranged that he should escape from the Duke’s dominions on the night of the masquerade, as it would be much easier for his wife to accompany him from thence than from the Grand Duke’s palace, which was well guarded; but it was necessary that they should travel on horseback, and they could not take their child with them. Viola would not consent that it should be left behind; and on this emergency he had written to his friend, the Count d’Ossore, to come to their assistance at the masquerade, and, that they might recognise him, to wear a sky-blue domino, a colour but seldom put on. The Count d’Ossore had that morning left his town mansion on a hunting excursion, and did not receive the letter, of which the Marquis and Viola were ignorant. Such was the state of affairs at the time that I put on the sky-blue domino to go to the masquerade.

My first meeting with the marquis in his violet-coloured domino is easily understood: being in a sky-blue domino I was mistaken for the Count d’Ossore. I was myself led into the mistake by the Marquis Albert having the same Christian name as my English friend. The second meeting with the Count Rodolph, in the black domino, was accidental. The next walk had been appointed as the place of meeting with the Carbonari Felippo and his companions; but Count Rodolph, perceiving me examining my stiletto by the light of the lamp, presumed that I was Felippo, and that I had mistaken the one path for the other which had been agreed upon. The papers given to me by Count Rodolph were Carbonari papers, which were to be hid in the marquis’s bosom after he had been assassinated, to make it appear that he had belonged I to that society, and by the paper affixed to his clothes, that he had been murdered by the agents of the society for having betrayed them. The papers which the marquis had requested me to give to the Grand Duke were the proofs of Count Rodolph’s belonging to the secret society; and with the papers was enclosed a letter to the Grand Duke, in which they I acknowledged their secret union. And now, I believe, the reader will comprehend the whole of this mysterious affair.

After all had been explained, I ventured to ask his Highness if he would permit me to fulfil my promise of taking the child to its mother, as I considered it a point of honour that I should keep my engagement, the more so, as the delay would occasion the greatest distress to his daughter; and I ventured to add, that I trusted his Highness would pardon what could not now be remedied, and that I should have the satisfaction of being the bearer of such pleasing intelligence to his daughter and the marquis.

The Grand Duke paced the room for a minute, and then replied, “Signor Herbert, I feel so disgusted with the treachery and baseness of Count Rodolph, that I hardly need observe, if my daughter were free he never should espouse her; indeed, he will have immediate orders to quit the state. You have been instrumental in preserving the life of the Marquis of Salerno, who is my son-in-law, and as matters now stand, I am indebted to you. Your dismissal of the bravoes, by means of the count’s ring, was a masterly stroke. You shall have the pleasure of taking my forgiveness to my daughter and her husband; but as for the child, it may as well remain here. Tell Viola I retain it as a hostage for the quick return of its mother.”

I took my leave of his Highness, and hastened to Pisa, where I soon found out the retreat of the marquis and his wife. I sent up my name, requesting immediate admittance, as having a message from the Grand Duke. I found them in great distress. The Count d’Ossore had returned late on the night of the masquerade, found the letter, hastened to the Marquesa de Cesto’s, and had arrived just after the elopement had been discovered. He immediately followed them to Pisa, when an explanation took place, and they discovered that they had been communicating with some unknown person, by whom they had, in all probability, been betrayed.

It would be difficult to portray their astonishment and joy when I entered into a detail of what had occurred, and wound up with the message from the Grand Duke; and I hardly need add, now that I wind up my story, that the proofs of gratitude I received from the marquis and his wife, during my subsequent residence in Italy, left me no occasion to repent that I had gone to the masquerade of the Marquesa de Cesto, in a Sky-Blue Domino.
