"Duke," said the Doctor, "let me first express my deepest thanks for your generous hospitality. Let me tell you how much your kindness has soothed the cruel suffering to which I have been subjected day and night for three weeks. I would, had it not been for your kindness, have weeks ago shared the captivity of René; and the hope I entertained of being of use to your daughter, alone prevented me from surrendering myself to despair at the prospect of a crushed and prospectless life, when I saw my brethren arrested in consequence of one whom I had always looked on as a devoted friend."

"Do not speak to me of that man," said the Duke in a terrible tone, "for my son, in my presence, charged him with having betrayed him."

"I have spoken to you of my gratitude," said the Doctor, "that you might not doubt it now at our separation."

"What danger now menaces you?" said the Duke, "why do you leave us?"

"To avoid being ungrateful," said Von Apsberg. "That you may never accuse your guest of selfishness, and that he may always deserve the esteem with which you honor him."

"What is the meaning of this mysterious language?"

"Grant me," said the young physician, with a trembling voice, "the boon of being permitted to keep the cause of my departure a secret. You would be as sorry to hear as I would be to tell you."

"No," said the old man, "I will not consent to this. You shall not quit the house which shelters you from your enemies: no, you shall not. Ah! sir," continued the Duke, "if you will not remain for your own sake do so for mine, for you alone have preserved the life of my daughter thus far." The Doctor said, as he gave a paper to the Duke: "Here is the result of my study, in which I have traced out all the means known to science calculated to strengthen the health of your daughter, and to parry the dangers which menace her."

"Doctor," said the Duke, "do not distress me by leaving the hotel. Do not make me perpetually miserable, Doctor, I am already unfortunate enough."

"Well," said the young man, unable to resist his prayers any longer, "you shall know what forces me to go, and shall yourself judge of my duty." He fell at the Duke's feet, and told him all he had learned during Marie's slumber, his combats with himself, and his resolution.
