"Perfectly," I assured him. "This is most interesting, although as yet it seems to me equally irrelevant."

"Your War Office," the Prince continued, "has established a Secret Council of Defence, whose only task it is to plan the successful resistance to that invasion, if ever it should take place. You, Mr. Ducaine, are, I believe, practically the secretary of that Council. You have to elaborate the digests of the meetings, to file schemes for the establishment of fortifications and camps; in a word, the result of these meetings passes through your hands. I will not beat about the bush, Mr. Ducaine. You can see that you have something in your keeping which, if passed on to me, would accomplish my whole aim. The army would be forced to acknowledge my claim upon them; the nation would hear of it."

"Well," I asked, "supposing all you say is true? What then?"

"You are a little obtuse, Mr. Ducaine," the Prince said softly. "If twenty thousand pounds would quicken your understanding—"

I picked up a small inkpot from the side of the table and hurled it at him. He sprang aside, but it caught the corner of his forehead, and he gave a shrill cry of pain. He struck a fierce blow at me, which I parried, and a moment later we were locked in one another's arms. I think that we must have been of equal strength, for we swayed up and down the room, neither gaining the advantage, till I felt my breath come short and my head dizzy. Nevertheless, I was slowly gaining the mastery. My grasp upon his throat was tightening. I had hold of his collar and tie, and I could have strangled him with a turn of my wrist. Just then the door opened. There was a quick exclamation of horrified surprise in a familiar tone. I threw him from me to the ground, and turned my head. It was Lady Angela who stood upon the threshold.

CHAPTER XIV

A RELUCTANT APOLOGY

Lady Angela looked at us both in cold surprise.

"Mr. Ducaine! Prince!" she exclaimed. "What is the meaning of this extraordinary exhibition?"

The Prince, whose sangfroid was marvellous, rose to his feet, and began to wipe his forehead with a spotless cambric handkerchief.
