I managed to take Bianca home without much difficulty, for it was my good fortune to meet a disengaged fiacre in one of the narrow streets leading to the piazza Vittorio Emanuele, and placing the poor girl therein, we drove straight to the Casa Angello. The Signorina was in a very excited state, as that menacing voice, issuing out of the darkness, had quite unnerved her; so, placing her in charge of Petronella, who made her lie down, I went for a doctor. Being a stranger in Verona it was difficult to find one, but at last I did so, and took him at once to see Bianca, for whom he prescribed a soothing draught, and assured me that she would be all right after a few hours' sleep. This trouble therefore being off my mind, I went back to my hotel, in order to consider what was best to be done in the present emergency.

I now saw that my surmise was right, and that the Contessa had hidden the body of the unfortunate Pallanza in the concealed tomb contrived by Count Mastino Morone for his guilty wife. It was a horribly ingenious idea that revolving pillar, and no one would have guessed its ghastly secret without being shown. Doubtless the wicked Donna Renata, shut up in this circular prison, had there starved slowly to death in an upright position, for, of course, the cavity was too narrow and too shallow to admit of any human being lying down. The skilful devilry of the device made me feel quite ill, especially when I thought how the worthy descendant of Borgia's accursed daughter had utilised this secret cell for her own infamous purpose. In this frightful oubliette the body of Guiseppe Pallanza would have remained for ever concealed; but then, according to the evidence of my own eyes, the body was not there.

That the Contessa had placed the corpse in the pillar I had not the slightest doubt, as in showing the hiding-place she evidently expected to overwhelm me by the hideous evidence of her barbarous criminality. That the cavity was empty was as much a surprise to her as to me, and the shriek of terror she had given when flying from the chamber showed me that she was overpowered with fear at the thought that her gruesome secret was shared by another person, for, putting me out of the question altogether, there appeared to be a third party implicated in this singular affair.

For my own part I believed it to be the man who had watched with me at the curtained archway, and who, after drugging me, bore me insensible from that terrible place. After doing so, and thus, according to his idea, putting it out of my power to re-discover the palace, he had returned to his post and seen the Contessa conceal the body of her victim in the cavity of the pillar. On her departure, for some reason best known to himself, he had removed the corpse, and hidden it somewhere else. This was, no doubt, the true story of the affair, but who was the man who had watched at the door, and who had taken away the body of Pallanza? It was impossible to guess the reasons for his behaving in this mysterious way, and the Contessa was evidently as ignorant as myself of his actions, judging from her terrified flight on discovering the truth. Whomsoever this unknown person was, he, to all appearances, held the key to the whole riddle, and, could I find him, I would doubtless learn the reason of Madame Morone's visit to the burial-ground, and the final fate of the unhappy tenor whom she had lured to his destruction.

But how to find him! that was the question, and one to which I could find no satisfactory answer; so in the dilemma in which I thus found myself involved, I decided to tell Luigi Beltrami, as the only friend I had in Verona, the whole devilish story. In addition to the desire I felt of asking his advice and opinion, I thought it but right that he should know the real character of the woman he was about to marry, and not discover too late that he was tied for life to a ghoul, a vampire, a murderess.

With this determination I looked for the card the Marchese had given me, and finding it in one of my pockets, discovered that my Italian friend lived in the Via Cartoni. As he had mentioned that he was always at home in the afternoon, doubtless to take a siesta during the heat of the day, on finishing my midday meal I went out to pay him a visit.

In spite of his assertion that he was poor, Beltrami had a sufficient income to warrant him living in a moderately expensive manner, and on my arrival at his rooms in the Via Cartoni, I was shown into a very well-furnished apartment. As the Marchese was stationed with his regiment at Verona for some considerable time, he had evidently brought a portion of his furniture from his Florentine palazzo, for the room was too handsome to be that of the ordinary class of furnished apartments. As usual, the ceiling was charmingly painted; the floor was of marble, covered here and therewith square Turkish carpets; and in addition to a piano there were plenty of pictures and photographs, showing the artistic taste of the owner of the place.

Beltrami himself, dressed as usual in his uniform, was seated at a desk placed in the window, writing letters, but he desisted when I was announced, and arose to greet me with marked cordiality.

"Ma foi, Hugo, this is kind of you to call so soon," he said when I was comfortably established in a chair. "I was just writing you a letter asking you to dine with me and go to the Ezzelino to-night, but as you are here the note is useless."

"The fact is, my dear Marchese, I have called on a selfish errand."

"Indeed!"

"Yes; still it is one that concerns yourself also."

"How so, mon ami? Come, tell me this mystery about which I know nothing and you know everything; but first here are some excellent cigarettes--Russian, my friend, not Italian. Dame! the tobacco of this country, it is horrible. Will you have some wine?"

"No, thank you, Beltrami, but I will be glad to smoke."

"Bene! help yourself."

He pushed the box towards me, and, after I had taken a cigarette, followed my example, the............
