“Very little,” I answered. “I am not even aware that I have done injury to Major Brennan, purposely or otherwise. He has not so much as honored me with information as to his cause for complaint. However, I care very little what it may be. As he has seen fit to denounce me before officers of my own corps, I should be extremely glad to meet him upon that ground alone; but after what we have just passed through together, I felt ready to blot out these past differences. Whatever they may have been, they are not liable to occur again, nor we to meet.”

“They have occurred again since you have been in this house!” Brennan broke forth excitedly. “You are not a coward, but I brand you here and now as sneak and liar! Now will you fight?”

We stood for a moment in utter silence, eye to eye, and I knew there was no help for it. These words, publicly spoken, left me no choice.

“I am at your service, Major Brennan,” I returned sternly, “now, or at any time. But I am unfortunate here in having no officer of my army present, and hence can name no second.”

“Doubtless one of these gentlemen will consent to serve,” he said, his face brightening at my rejoinder.

There was a moment of hesitation, natural enough, for they could scarcely feel like pitting themselves against a brother officer in a quarrel the merits of which were so obscure. I was about to speak, volunteering to stand alone, when some one hastily pushed a way to the front, and Lieutenant Caton, pale but determined, stood at my shoulder.

“It will afford me pleasure to act for Captain Wayne,” he said clearly, “if he will accept my services. Moreover,” he added, with a significant glance at Brennan, “I do this as a friend, and with full confidence that I am upon the right side in the quarrel.”

For a moment no one spoke, Brennan biting his moustache to keep back words he durst not utter. Then Caton turned to me.

“If you will retire to the library, Wayne, I will arrange this matter with whoever may represent Major Brennan.”

With a slight formal bow to those present I quitted the room.
