He pointed to a building we were in the act of approaching.
"There it is, signor," he said. "At one time it was a very great palace but now—" here he shrugged his shoulders to enable us to understand that its glory had departed from it. Not another word was said upon the subject, but I noticed that all our faces turned in the direction of the building. With the exception of one solitary window it was in total darkness. As I looked at the latter I wondered whether Nikola were in the room, and if so, what he was doing? Was he poring over some of his curious books, trying some new experiment in chemistry, or putting to the test some theory such as I had found him at work upon in that curious house in Port Said? A few minutes later we had left the Rio del Consiglio behind us, had turned to the right, and were making our way back by another watery thoroughfare towards the Grand Canal.
"Thanks to your proposition we have had a delightful evening," Miss Trevor said, as we paused to say good-night at the foot of the staircase a quarter of an hour or so later. "I have enjoyed myself immensely."
"You should not tell him that, dear," said my wife. "You know how conceited he is already. He will take all the credit, and be unbearable for days afterwards." Then turning to me, she added, "You are going to smoke, I suppose?"
"I had thought of doing so," I replied; and then added with mock humility, "If you do not wish it of course I will not do so. I was only going to keep Glenbarth company."
They laughed and bade us good-night, and when we had seen them depart in the direction of their rooms we lit our cigars and passed into the balcony outside.
At this hour of the night the Grand Canal looked very still and beautiful, and we both felt in the humour for confidences.
"Do you know, Hatteras," said Glenbarth, after the few moments' pause that followed our arrival in the open air, "that Nikola's turning up in Venice at this particular juncture savours to me a little of the uncanny. What his mission may be, of course I cannot tell, but that it is some diabolical thing or another I haven't a doubt."
"One thing is quite certain," I answered, "he would hardly be here without an object, and, after our dealings with him in the past, I am prepared to admit that I don't trust him any more than you do."
"And now that he has asked you to call upon him what are you going to do?"
