"You will not be able to understand me," he said; "nevertheless, I tell you that the end is brought nearer by that one scene. It will not be long before it comes now. All things considered, I do not know that I shall regret it."

Then, without another word, he strode away into the darkness, leaving me to place what construction I pleased upon his last speech. For some moments I stood where he had left me, pondering over his words, and then set off in the direction I had come. As may be imagined, I felt even less inclined than before for the happy, jovial party I knew I should find on board the steamer, but I had given my promise, and could not get out of it. When I reached the piazza of St. Mark once more I went to the steps and hailed a gondola, telling the man to take me to the P. and O. vessel then lying at anchor in the harbour. He did so, and I made my way up the accommodation-ladder to the deck above, to find that the passengers in the first saloon had just finished their dinner, and were making their appearance on the promenade deck. I inquired of the steward for Mr. Beckworth, and discovered him in the act of lighting a cigar at the smoking-room door.

He greeted me effusively, and begged me to remain where I was while he went in search of his wife. When she arrived, I found her to be a pretty little woman, with big brown eyes, and a sympathetic manner. She was good enough to say that she had heard such a lot concerning me from her husband, and had always looked forward to making my acquaintance. I accepted a cigar from Beckworth's case, and we then adjourned to the smoking-room for a long talk together. When we had comfortably installed ourselves, my friend's flow of conversation commenced, and I was made aware of all the principal events that had occurred in Queensland since my departure, was favoured with his opinion of England, which he had never before visited, and was furnished with the details as to how he had met his wife, and of the happy event with which their courtship had been concluded.

"Altogether," he said, "taking one thing with another, I don't know that you'd be able to find a much happier fellow in the world than I am at this moment."

I said I was glad to hear it, and as I did so contrasted his breezy, happy-go-lucky manner with those of certain other people I had been brought in contact with that day. My interview with him must have done me good, for I stayed on, and the hour was consequently late when I left the ship. Indeed, it wanted only a few minutes of eleven o'clock as I went down the accommodation-ladder to the gondola, which I had ordered to come for me at ten.

"Galaghetti's hotel," I said to the man, "and as quickly as you can."

When I had bade my friends "good-bye" and left the ship, I felt comparatively cheerful, but no sooner had the silence of Venice closed in upon me again than all my old despondency returned to me. A foreboding of coming misfortune settled upon me, and do what I would I could not shake it off.

When I reached the hotel I found that my party had retired to rest. My wife was sleeping quietly, and not feeling inclined for bed, and dreading lest if I did go I might be assailed by more dreams of a similar description to that I had had on the previous night, I resolved to go back to the drawing-room and read there for a time. This plan I carried into execution, and taking up a new book in which I was very much interested, seated myself in an easy-chair and determined to peruse it. I found some difficulty, however, in concentrating my attention upon it. My thoughts continually reverted to my interview that afternoon with Nikola, and also to the scene I had witnessed in the poorer quarter after dark. I suppose eventually I must have fallen asleep, for I remember nothing else until I awoke to find myself sitting up and listening to a light step in the corridor outside. I looked at my watch to discover that the time was exactly a quarter to one. In that case, as we monopolized the whole of the corridor, who could it be? In order to find out I went to the door, and softly opened it. A dim light was always left in the passage throughout the night, and by it I was able to see a tall and graceful figure, which I instantly recognized, making for the secondary stairs at the further end. Now these stairs, so I had been given to understand, led to another portion of the hotel into which I had never penetrated. Why, therefore, Miss Trevor was using them at such an hour, and, above all, dressed for going out, I could not for the life of me determine. I could see that, if I was anxious to find out, I must be quick; so, turning swiftly into the room again, I picked up my hat and set off in pursuit. As the sequel will prove, it was, perhaps, as well that I did so.

By the time I reached the top of the stairs she was at the bottom, and was speeding along another passage to the right. At the end of this was a door, the fastenings of which she undid, with an ease and assurance that bewildered me. So certain was she of her whereabouts, and so easily did she manipulate the heavy door, that I felt inclined to believe that she must have used that passage many times before. At last she opened it and passed out into the darkness, drawing it to after her. I had paused to watch her; now I hastened on even faster than before, fearing that, if I were not careful, I might lose her outside. Having passed the door I found myself in a narrow lane, bounded on either side by high walls, and some fifty or sixty yards in extent. The lane, in its turn, opened into a small square, out of which led two or three other narrow streets. She turned to the left and passed down one of these; I followed close upon her heels. Of all the strange experiences to which our stay in Venice had given rise, this was certainly one of the most remarkable. That Gertrude Trevor, the honest English girl, the daughter of a dignitary of the Church and a prospective bishop, should leave her hotel in the middle of the night in order to wander about streets with which she was most imperfectly acquainted, was a mystery I found difficult to solve. When she had crossed a bridge, which spanned a small canal, she once more turned to the left, passed along the footway before a dilapidated palace, and then entered a narrow passage on the right. The buildings hereabouts were all large, and, as a natural consequence, the streets were so dark that I had some difficulty in keeping her in sight. As a matter of fact she had stopped, and I was almost upon her before I became aware of it. Even then she did not seem to realize my presence. She was standing before a small door, which she was endeavouring to push open. At last she succeeded, and without hesitation began to descend some steps inside. Once more I took up the chase, though where we were, and what we were going to do there, I had not the least idea. The small yard in which we found ourselves was stone-paved, and for this reason I wondered that she did not hear my footsteps. It is certain, however, that she did not, for she made for a door I could just discern on the opposite side to that by which we had entered, without turning her head. It was at this point that I began to wish I had brought a revolver or some weapon with me. When she was about to open the door I have just mentioned, I called her softly by name, and implored her to wait for me, but still she took no notice. Could she be a somnambulist? I asked myself. But if this were so, why had she chosen this particular house? Having passed the door we stood in a second and larger courtyard, and it was then that the whole mystery became apparent to me. The house to which I had followed her was the Palace Revecce, and she was on her way to Nikola! But for what reason? Was this a trick of Nikola's, or had her terrible dreams taken such a hold upon her that she was not responsible for her actions? Either alternative was bad enough. Pausing for a moment in the courtyard beside the well, she turned quickly to her right hand and began to ascend the stairs towards that awful room, which, so far as I knew, she had never visited before. When she reached it I scarcely knew how to act. Should I enter behind her and accuse Nikola of having enticed her there, or should I wait outside and overhear what transpired between them? At last I made up my mind to adopt the latter course, and, when she had entered, I accordingly remained outside and waited for her. Through the half-open door I could see Nikola, stooping over what looked like a microscope at a side-table. He looked up as Miss Trevor entered, and uttered a cry of surprise. As I heard this a sigh of relief escaped me, for his action proved to me that her visit had not been anticipated.

"Miss Trevor!" he said, moving forward to greet her, "what does this mean? How did you get here?"
