"Ah! my dear friend," taking her hands, "be at ease; he has confided all to me. You have come, you are good, you will save him;" and he carried Caroline's hands to his lips with genuine affection.

"But," said she, slightly astonished, "knowing him to be so ill, why did you leave him to-night? And since you counted upon my care for him, why did you not tell me it was needed?"

"What, then, has happened?" asked the Duke, who perceived that they did not understand each other. She told him briefly what had occurred, and as, absorbed by what he was hearing, he conducted her back across the grass-plot to the stairs of the Fox turret, Madame d'Arglade, who was already upon her feet behind the casement of her window, saw them pass, talking in a low voice with an air of mysterious intimacy. They stopped before the door, and stood talking awhile longer. The Duke gave Mlle de Saint-Geneix an account of his attempt to bring a physician to see his brother, and Caroline dissuaded him from that design. She believed that the directions she had read would be sufficient, and that it would be highly imprudent to adopt a new treatment when they were aware that the first one had been attended with beneficial results. The Duke readily promised her to conform to this advice, and consequently to have confidence in it. Madame d'Arglade saw them take each other by the hand at parting, and the Duke, retracing his steps, ascend the stairs of the Griffin turret.

"Very well, I have seen enough," thought Léonie; "and I have n't to run about in the dew, which I don't like to do at all; I can lie abed the whole forenoon." And in getting herself to sleep again; "That Caroline!" she said to herself, "I see plainly that she lied. How probable it is that the Duke would allow her to go free! But I will keep it, this fine secret of hers, and if ever I have need of her, she will of course have to do as I wish."

Caroline retired quickly, that she might get quickly to sleep, so as to return to the service of her patient.

At eight o'clock she was up and looked through her window. The Duke was at that of his brother. He made her a sign that he would go through the halls and meet her in the library. She went thither immediately from her side of the house, and there she learned that the Marquis was remarkably well. He had just awakened, and he had said, "Heavens, what a miracle! This is my first sleep after a whole week of this suffering, and I no longer feel any pain; I breathe freely; it seems to me that I am cured. It is to her that I owe it all!"—"and it is the truth, my dear friend," added the Duke; "it is you who have saved him, and who will preserve him for us, if you have pity upon us."

The Duke had resolved to say nothing; he had sworn it to his brother; but, although thinking himself very discreet, he had let the truth escape him in his own despite. That truth darted through the mind of Caroline like a flash of lightning. "What is it that your Grace says?" cried she. "Who am I, and how am I here to have such an influence?"

The Duke himself was frightened by the frightened look of Caroline. "Come, in whom are you disappointed?" he said, resuming the mask of his tranquil smile. "What is that you have got into your head now? Do you not see that I worship my brother, that I am in great fear of losing him, and that, because of the assistance you were to him last night, I speak to you as if you were my sister? I am very much embarrassed; I lose my senses, do you see? Urbain is killing himself with work. My influence over him is not sufficient; he does not want me to inform our mother of the return of his old disorder. Informing her would be indeed to agitate her dangerously; infirm as she is, she would be always with him to watch. At the end of two nights she would succumb to her exertions. It remains for us two, therefore, to save my brother, without seeming to do so, without taking the lackeys and chambermaids into our confidence. That sort of people will always talk. Come, are you a woman of heart and head as I have persuaded myself that you are? Will you, can you, dare you, seriously, aid me to nurse him in secret, and watch alternately with me for several evenings, several nights if necessary, never leaving him alone an hour, so that even for an hour he cannot betake himself again to his accursed old books! He needs nothing, I feel sure, but absolute repose of mind, sufficient sleep, a little walking, and that he should try to eat. To bring these things about, it requires the despotic authority—yes, the despotic authority of some one who is not afraid to go counter to his will—of some devoted heart not easily moved or harshly immovable, or unseasonably distrustful,—some one who will bear with his whims if he should have any, and with the impulsive excesses of his gratitude if such should escape him,—a serious friend,in a word, who shall have such delicate, intelligent charity for him as will make him accept and perhaps love his yoke. Well, now, Caroline, you are the only one here who can be that person. My brother has great esteem, profound respect, and, I believe, even a sincere friendship for you. Try to govern him a week, a fortnight, a month perhaps, for if he could get up to-day he would be here this evening turning over the leaves of his books and taking notes; if he sleeps again to-night he will believe himself through with the whole thing, and will not go to bed at all the next night. You see what task we ought to impose upon ourselves. As for my part, I am resolved upon it, entirely devoted to it, but by myself alone I can do nothing. I shall weary him, he will allow no one but me to see him, and his impatience will neutralize the effect of my care. With you,—a woman, a voluntary guardian, generous, firm and tender, patient and resolute, as women only know how to be,—I will answer for it that he will submit without ill-will, and later, when all the paroxysms of his disorder are passed, he will bless you for having thwarted him."

This insidious explanation of the case entirely dissipated the vague and sudden suspicion of Caroline. "Yes, yes," she answered, with decision, "I will be that guardian. Count upon me; I thank you for having chosen me, and do not think better of me on that account. I am used to nursing; it costs me neither effort nor fatigue. Your brother is to me, as to you, so worthy of respect and so superior to every one we know that it is a happiness and honor to serve him. Let us, therefore, understand each other, so that we can share this good task without arousing suspicion of any one around us here as to his real state. To begin with, you install yourself in his room to-night."

"He will not allow that."
