This conversation almost deprived me of the power to think. In a dimly conscious fashion, I wondered whether Castleman could possibly have meant the Duke of Burgundy when he told Yolanda that her father would soon be at Peronne. I could find no other meaning for his words, and I was almost ready to believe that the brown-eyed, laughing Yolanda was none other than the far-famed Mary of Burgundy, whose tiny hand was sought by every nation of Europe having a marriageable king or prince. Kings in their dotage and princes in their nonage wooed her. Old men and babes eagerly sought the favor of this young girl, and stood ready to give their gold, their blood, and the lives of their subjects on even the shadow of a chance to win her. The battle-field and the bower alike had been wooing-ground for her smiles. After all this, she had been affianced to the Dauphin of France, and her father would bring the marriage about within a few weeks. To this girl I had thought to be gracious, and had feared that I might be too condescending. I then realized what a pitiable ass a man may make of himself by giving his whole time and attention to the task. Of course I was not sure that Yolanda was the princess. Her father, spoken of by Castleman, might be, and probably was, a great lord in the duke's train. Yolanda might be the love-daughter of Charles of Burgundy. Many explanations might be given to Castleman's remarks; but I could not help believing that Yolanda was the far-famed Burgundian princess. If so, what a marvellous romance was this journey that Max and I had undertaken, and what a fantastic trick fate had played in bringing these two from the ends of the earth to meet in the quaint old Swiss city. It seemed almost as if their souls had journeyed toward each other, since the beginning of time. That the princess should be abroad with Castleman and his daughter unattended by even a lady-in-waiting seemed improbable--almost impossible. My wavering mind veered with each moment from the conviction that Yolanda was the princess to a feeling of certainty that she was not, and back again. That she was the princess seemed at one moment indubitably true; the next moment it appeared absurdly impossible. Still, Castleman's words rang in my ears. I was glad that Max was riding a hundred yards behind me. My first determination was that he should know nothing of what I had heard. My second was that he and I should leave the party at Metz. If I were to disclose to Max my suspicions concerning Yolanda, I well knew that it would be beyond my power or that of any man to prevent his journeying to Peronne.
