"One night," she went on, "one night--I was only ten--and my mother, with the remains of her superhuman energy, for she was near her end that night, came to me when I lay asleep. It was in winter; a stony cold hand caught me by the wrist. I looked up. Before me stood a tall woman; in one hand she held a flaming torch, with the other she held me by the arm. Her robe was sprinkled with snow. There was a convulsive movement in all her limbs and her eyes were fired with a gloomy light through the long locks of white hair which hung in disorder round her face. It was my mother; and she said, 'Odile, my child, get up and dress! You must know it all!' Then taking me to Hugh Lupus's tower she showed me the open subterranean passage. 'Your father will come out that way,' she said, pointing to the tower; 'he will come out with the she-wolf; don't be frightened, he won't see you.' And presently my father, bearing his funereal burden, came out with the old woman. My mother took me in her arms and followed; she showed me the dismal scene on the Altenberg of which you know. 'Look, my child,' she said; 'you must for I--am going to die soon. You will have to keep that secret. You alone are to sit up with your father,' she said impressively--'you alone. The honour of your family depends upon you!' And so we returned. A fortnight after my mother died, leaving me her will to accomplish and her example to follow. I have scrupulously obeyed her injunctions as a sacred command, but oh, at what a sacrifice! You have seen it all. I have been obliged to disobey my father and to rend his heart. If I had married I should have brought a stranger into the house and betrayed the secret of our race. I resisted. No one in this castle knows of the somnambulism of my father, and but for yesterday's crisis, which broke down my strength completely and prevented me from sitting up with my father, I should still have been its sole depositary. God has decreed otherwise, and has placed the honour and reputation of my family in your keeping. I might demand of you, sir, a solemn promise never to reveal what you have seen to-night. I should have a right to do so." "Madam," I said, rising, "I am ready." "No, sir," she replied with much dignity, "I will not put such an affront upon you. Oaths fail to bind base men, and honour alone is a sufficient guarantee for the upright. You will keep that secret, sir, I know you will keep it, because it is your duty to do so. But I expect more than this of you, much more, and this is why I consider myself obliged to tell you all!" She rose slowly from her seat. "Doctor Fritz," she resumed in a voice which made every nerve within me quiver with deep emotion, "my strength is unequal to my burden; I bend beneath it. I need a helper, a friend. Will you be that friend?"
