"You need not worry yourself," I said. "In all probability you will see no more of him. I shall convey a hint to him upon the subject. It will not be pleasant for Anstruther's sake."

"Mr. Anstruther should have known better than to have sent him to us," she replied. "There is one thing I am devoutly thankful for, and that is that the Duke took it so beautifully. He might have been angry, and have made a scene. Indeed I should not have blamed him, had he done so."

I did not ask her, for reasons of my own, whether she was sure that his Grace of Glenbarth was not angry. I must confess that I was rendered more uneasy by the quiet way he had taken it, than if he had burst into an explosion. Concealed fires are invariably more dangerous than open ones.

Next morning after breakfast, while we were smoking together in the balcony, a note was brought to Glenbarth. He took it, opened it, and when he had read the contents, thrust it hastily into his pocket.

"No answer," he said, as he lit a cigar, and I thought his hand trembled a little as he put the match to it.

His face was certainly paler than usual, and there was a far-away look in his eyes that showed me that it was not the canal or the houses opposite that he was looking upon.

"There is something behind all this, and I must find out what it is," I said to myself. "Surely he can't be going to make a fool of himself."

I knew, however, that my chance of getting anything satisfactory out of him lay in saying nothing about the matter just then. I must play my game in another fashion.

"What do you say if we run down to Rome next week?" I asked, after a little pause. "My wife and Miss Trevor seem to think they would enjoy it. There are lots of people we know there just now."

"I shall be very pleased," he answered, but with a visible effort.
