I felt a warm rush of joy, of triumph, of coming vengeance. "Thank you, Madame," I said, and I bowed to her, "for telling me that. It seems, then, that you are in my power." "Ah?" "And that to requite you for the pain you have just caused Mademoiselle, I have only to leave you." "Well?" "I see even now a little town before us; in three minutes we shall enter it. Very well, Madame. If you say another word to your daughter, if you insult her again in my presence by so much as a syllable, I leave you and go my way." To my surprise Madame St. Alais broke into a silvery laugh. "You will not, Monsieur," she said. "And yet I shall treat my daughter as I please." "I shall do so!" "You will not." "Why, then? Why shall I not?" I cried. "Because," she answered, laughing softly, "you are a gentleman, M. le Vicomte, and can neither leave us nor endanger us. That is all." I sank back in my seat, and glared at her in speechless indignation; seeing in a flash my impotence and her power. The cushions burned me; but I could not leave them. She laughed again, well pleased. "There, I have told you what you will not do," she said. "Now I am going to tell you what you will do. In front, I am told, they are very suspicious. The story of Madame Corvas, even if backed by your word, may not suffice. You will say, therefore, that I am your mother, and that Mademoiselle is your sister. She would prefer, I daresay," Madame continued, with a cutting glance at her daughter, "to pass for your wife. But that does not suit me." I breathed hard; but I was helpless as any prisoner, closely bound to obedience as any slave. I could not denounce them, and I could not leave them; honour and love were alike concerned. Yet I foresaw that I must listen, hour by hour, and mile by mile, to gibes at the girl's expense, to sneers at her modesty, to words that cut like whip-lashes. That was Madame's plan. The girl must travel with me, must breathe the same air with me, must sit for hours with the hem of her skirt touching my boot. It was necessary for the safety of all. But, after this, after what we had both heard, if her eye met mine, it could only fall; if her hand touched mine, she must shrink in shame. Henceforth there was a barrier between us. As a fact, Mademoiselle's pride came to her aid, and she sat, neither weeping nor protesting, nor seeking to join her forces to mine by a glance; but bearing all with steadfast patience, she looked out of the window when I pretended to sleep, and looked towards her mother when I sat erect. Possibly she found her compensations, and bore her punishment quietly for their sake. But I did not think of that. Possibly, too, she suffered less than I fancied; but I doubt if she would admit that, even to-day.
