"Perhaps I should remind you young people that at the present moment you are in a church," I said. "Would it not be as well, do you think, for you to preserve those pretty little prevarications until you are in the gondola? You will be able to quarrel in greater comfort there. It will also give Phyllis time to collect her thoughts, and to prepare a new indictment."

My wife treated me to a look that would have annihilated another man. After that I washed my hands of them and turned to the copy of Titian's Martyrdom of Saint Peter, which Victor Emmanuel had presented to the church in place of the original, which had been destroyed. Later on we made our way, by a long series of tortuous thoroughfares, to the piazza of Saint Mark, where we intended to sit in front of Florian's café and watch the people until it was time for us to return and dress for dinner.

As I have already said, Miss Trevor had all the afternoon been in the best of spirits. Nothing could have been happier than her demeanour when we left the church, yet when we reached the piazza everything was changed. Apparently she was not really unhappy, nor did she look about her in the frightened way that had struck me so unpleasantly on the previous evening. It was only her manner that was strange. At first she was silent, then, as if she were afraid we might notice it, she set herself to talk as if she were so doing for mere talking's sake. Then, without any apparent reason, she became as silent as a mouse once more. Remembering what had happened that morning before breakfast, I did not question her, nor did I attempt to rally her upon the subject. To have done either would have been to have risked a recurrence of the catastrophe we had so narrowly escaped earlier in the day. I accordingly left her alone, and my wife, in the hope of distracting her attention, entered upon an amusing argument with Glenbarth upon the evils attendant upon excessive smoking, which was the young man's one, and, so far as I knew, only failing. Unable to combat her assertions he appealed to me for protection.

"Take my part, there's a good fellow," he said pathetically. "I am not strong enough to stand against Lady Hatteras alone."

"No," I returned; "you must fight your own battles. When I see a chance of having a little peace I like to grasp it. I am going to take Miss Trevor to Maya's shop on the other side of the piazza, in search of new photographs. We will leave you to quarrel in comfort here."

So saying Miss Trevor and I left them and made our way to the famous shop, where I purchased for her a number of photographs, of which she had expressed her admiration a few days before. After that we rejoined my wife and Glenbarth and returned to our hotel for dinner.

Nikola, as you may remember, had arranged to call for us with his gondola at half-past eight, and ten minutes before that time I suggested that the ladies should prepare themselves for the excursion. I bade them wrap up well, for I knew by experience that it is seldom warm upon the water at night. When they had left us the Duke and I strolled into the balcony.

"I hope to goodness Nikola won't frighten Miss Trevor this evening," said my companion, after we had been there a few moments. (I noticed that he spoke with an anxiety that was by no means usual with him.) "She is awfully sensitive, you know, and when he likes he can curdle the very marrow in your bones. I shouldn't have liked her to have heard that story he told us this morning. I suppose there is no fear of his repeating it to-night?"

"I should not think so," I returned. "Nikola has more tact in his little finger than you and I have in our whole bodies. He would be scarcely likely to make such a mistake. No, I rather fancy that to-night we shall see a new side of his character. For my own part I am prepared to confess that I am looking forward to the excursion with a good deal of pleasure."

"I am glad to hear it," Glenbarth replied, as I thought with a savour of sarcasm in his voice. "I only hope you won't have reason to regret it."
