"You shall be my knight and champion, and I say it seriously. I may call you to fight for me, at least to defend and protect me in my present undertaking. The way is by no means clear. I cannot foresee what may happen on this journey. There are risks, dangers before me. I may ask you to share them. Do you repent already?"

She had been watching me closely for any sign of wavering, but I showed none, whatever I might feel in my inmost heart.

"I shall not disappoint you," was what I said, and, in a firm assured voice, added, "You have resolved then to travel forward in this train?"

"I must, I have no choice. I dare not tarry by the way. But I no longer feel quite alone and unprotected. If trouble arises, I tell you candidly I shall try to throw it on you."

"From what quarter do you anticipate it?" I asked innocently enough. "You expect to be pursued, I presume?"

She held up a warning finger.

"That is not in the compact. You are not to be inquisitive. Ask me no questions, please, but wait on events. For the present you must be satisfied so, and there is nothing more to be said."

"I shall see you again, I trust," I pleaded, as she rose to leave me.

"If you wish, by all means. Why should we not dine together in the dining-car by and by?" she proposed with charming frankness, in the lighter mood that sat so well upon her. "The waiters will be there to play propriety, and no Mrs. Grundy within miles."
