"What have they to quarrel about?" I asked. "They have nothing in common."

"That only proves how blind you are to what goes on around you," my wife replied. "Have you not noticed that they both admire Gertrude Trevor?"

Falling so pat upon my own thoughts, this gave me food for serious reflection.

"How do you know that Nikola admires her?" I asked, a little sharply, I fear, for when one has uncomfortable suspicions one is not always best pleased to find that another shares them. A double suspicion might be described as almost amounting to a certainty.

"I am confident of it," she replied. "Did you not notice his manner towards her on the night of our excursion? It was most marked."

"My dear girl," I said irritably, "if you are going to begin this sort of thing, you don't know where you will find yourself in the end. Nikola has been a wanderer all his life. He has met people of every nationality, of every rank and description. It is scarcely probable, charming though I am prepared to admit she is, that he would be attracted by our friend. Besides, I had it from his own lips this morning that he will never marry."

"You may be just as certain as you please," she answered. "Nevertheless, I adhere to my opinion."

Knowing what was in my own mind, and feeling that if the argument continued I might let something slip that I should regret, I withdrew from the field, and, having questioned her concerning certain news she had received from England that day, bade her good-night.

Next morning we paid a visit to the Palace of the Doges, and spent a pleasant and instructive couple of hours in the various rooms. Whatever Nikola's feelings may have been, there was by this time not the least doubt that the Duke admired Miss Trevor. Though the lad had known her for so short a time he was already head over ears in love. I think Gertrude was aware of the fact, and I feel sure that she liked him, but whether the time was not yet ripe, or her feminine instinct warned her to play her fish for a while before attempting to land him, I cannot say; at any rate she more than once availed herself of an opportunity and moved away from him to take her place at my side. As you may suppose, Glenbarth was not rendered any the happier by these manœuvres; indeed, by the time we left the Palace, he was as miserable a human being as could have been found in all Venice. Before lunch, however, she relented a little towards him, and when we sat down to the meal in question our friend had in some measure recovered his former spirits. Not so my wife, however; though I did not guess it, I was in for a wigging.

"How could you treat the poor fellow so badly?" she said indignantly, when we were alone together afterwards. "If you are not very careful you'll spoil everything."
