"He seems to affect every one in a different manner," I said, and for some reason made no further comment upon her speech.
When we had called a gondola, and were on our way back to our hotel, she referred to the subject again.
"I think I ought to tell you that it is not the first time I have seen Doctor Nikola," she said. "You may remember that yesterday, while Phyllis was lying down, I went out to do some shopping. I cannot describe exactly which direction I took, save that I went towards the Rialto. It is sufficient that in the end I reached a chemist's shop. It was only a small place, and very dark, so dark indeed that I did not see that it contained another customer until I was really inside. Then I noticed a tall man busily engaged in conversation with the shopman. He was declaiming against some drugs he had purchased there on the previous day, and demanding that for the future they should be of better quality, otherwise he would be compelled to take his patronage elsewhere. In the middle of this harangue he turned round, and I was permitted an opportunity of seeing his face. He was none other than your friend, Doctor Nikola."
"But, my dear Gertrude," said Phyllis, "with all due respect to your narrative, I do not see that the mere fact of your having met Doctor Nikola in a chemist's shop yesterday, and your having been introduced to him to-day, should have caused you so much concern."
"I do not know why it should," she answered, "but it is a fact, nevertheless. Ever since I saw him yesterday, his face, with its terrible eyes, has haunted me. I dreamt of it last night. All day long I have had it before me, and now, as if to add to the strangeness of the coincidence, he proves to be the man of whom you have so often told me—your demoniacal, fascinating Nikola. You must admit that it is very strange."
"A coincidence, a mere coincidence, that is all," I replied. "Nikola possesses an extraordinary face, and it must have impressed itself more deeply upon you than the average countenance is happy enough to do."
Whether my explanation satisfied her or not, she said no more upon the subject. But that our strange meeting with Nikola had had an extraordinary effect upon her was plainly observable. As a rule she was as bright and merry a companion as one could wish to have; on this particular evening, however, she was not herself at all. It was the more annoying for the reason that I was anxious that she should shine on this occasion, as I was expecting an old friend, who was going to spend a few days with us in Venice. That friend was none other than the Duke of Glenbarth, who previous to his succession to the Dukedom had been known as the Marquis of Beckenham, and who, as the readers of the history of my adventures with Doctor Nikola may remember, figured as a very important factor in that strange affair. Ever since the day when I had the good fortune to render him a signal service in the bay of a certain south-coast watering-place, and from the time that he had accepted my invitation to join us in Venice, I had looked forward to his coming with the greatest possible eagerness. As it happened it was well-nigh seven o'clock by the time we reached our hotel. Without pausing in the hall further than to examine the letter-rack, we ascended to our rooms on the floor above. My wife and Miss Trevor had gone to their apartments, and I was about to follow their example as soon as I had obtained something from the sitting-room.
"A nice sort of host, a very nice host," said a laughing voice as I entered. "He invites me to stay with him, and is not at home to bid me welcome. My dear old Dick, how are you?"
"My dear fellow," I cried, hastening forward to greet him, "I must beg your pardon ten thousand times. I had not the least idea that you would be here so early. We have been sitting on the piazza, and did not hurry home."
"You needn't apologize," he answered. "For once an Italian train was before its time. And now tell me about yourself. How is your wife, how are you, and what sort of holiday are you having?"
I answered his questions to the best of my ability, keeping back my most important item as a surprise for him.
"And now," I said, "it is time to dress for dinner. But before you do so, I have some important news for you. Who do you think is in Venice?"
Needless to say he mentioned every one but the right person.
"You had better give it up, you will never guess," I said. "Who is the most unlikely person you would expect to see in Venice at the present moment?"
"Old Macpherson, my solicitor," he replied promptly. "The rascal would no more think of crossing the Channel than he would contemplate standing on his head in the middle of the Strand. It must be Macpherson."
"Nonsense," I cried. "I don't know Macpherson in the first place, and I doubt if he would interest me in the second. No! no! this man is neither a Scotchman nor a lawyer. He is an individual bearing the name of Nikola."
I had quite expected to surprise him, but I scarcely looked for such an outbreak of astonishment.
"What?" he cried, in amazement. "You must be joking. You don't mean to say that you have seen Nikola again?"
"I not only mean that I have seen him," I replied, "but I will go further than that, and say that he was sitting on the piazza with us not more than half-an-hour ago. What do you think his appearance in Venice means?"
"I don't know what to think," he replied, with an expression of almost comic bewilderment upon his face. "It seems impossible, and yet you don't look as if you were joking."
"I tell you the news in all sober earnestness," I answered, dropping my bantering tone. "It is a fact that Nikola is in Venice, and, what is more, that he has given me his address. He has invited me to call upon him, and if you like we will go together. What do you say?"
"I shall have to take time to think about it," Glenbarth replied seriously. "I don't suppose for a moment he has any intention of abducting me again; nevertheless, I am not going to give him the opportunity. By Jove, how that fellow's face comes back to me. It haunts me!"
"Miss Trevor has been complaining of the same thing," I said.
"Miss Trevor?" the Duke repeated. "And pray who may Miss Trevor be?"
"A friend of my wife's," I answered. "She has been travelling with us for the last few months. I think you will like her. And now come along with me and I'll show you your room. I suppose your man has discovered it by this time?"
"Stevens would find it if this hotel were constructed on the same principle as the maze at Hampton Court," he answered. "He has the virtue of persistence, and when he wants to find a thing he secures the person who would be the most likely to tell him, and sticks to him until his desire has been gratified."
It turned out as he had predicted, and three-quarters of an hour later our quartet sat down to dinner. My wife and Glenbarth, by virtue of an old friendship, agreed remarkably well, while Miss Trevor, now somewhat recovered from her Nikola indisposition, was more like her old self. It was a beautiful night, and after dinner it was proposed, seconded, and carried unanimously, that we should charter a gondola and go for a row upon the canal. On our homeward voyage the gondolier, by some strange chance, turned into the Rio del Consiglio.
"Perhaps you can tell me which is the Palace Revecce?" I said to the man.
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.
