The young girl and the marquise left Madame Dutertre, who, yielding in spite of herself to the conviction which seemed to ring from Madeleine's words, returned to her dwelling with a ray of hope. The prince waited for Madeleine in the parlour of President Hubert; he saluted her respectfully, and said to her, with that ceremonious formality which Antonine's presence imposed:
"I had it in my heart, marquise, to thank you for the great service you have rendered me. You have put it in my power to appreciate Mlle. Hubert as she deserves to be; the happiness of my godson Frantz is for ever assured. I have agreed with M. President Hubert, who willingly consents to it, that to-morrow morning the betrothal of Frantz and Mlle. Hubert will take place according to the German custom, that is to say, that I and President Hubert will sign, under penalty of perjury and infidelity, the contract of marriage which Frantz and mademoiselle will sign under the same conditions."
"Since you have said to Antonine, monseigneur, that I have put you in the way of truth, Antonine is under obligation to prove to you all the good that I have told you of her."
"I have a favour to ask of you, marquise," continued the prince, drawing from his pocket a letter and presenting it to Madeleine. "You are acquainted with the family of Colonel Pernetti?"
"Very well, monseigneur."
"Then do me the kindness to have this letter delivered to the colonel, after you have taken knowledge of its contents. I am certain," added the archduke, emphasising his last words, "that you will have as much pleasure in sending this letter as he to whom it is addressed will have pleasure in receiving it."
"I do not doubt it, monseigneur, and I here renew my very sincere thanks," said the marquise, making a ceremonious curtsey.
"To-morrow, Mlle. Antonine," said the prince to the young girl, "I am going to break the good news very gently to my poor Frantz, for fear he may be overcome by his emotion; but I am certain when he knows all he, like you, will forgive me for the grief I have caused him."
And, after having again formally saluted Antonine and the marquise, with whom he exchanged a look of intelligence, the prince returned to the Élysée-Bourbon.
The next day at ten o'clock Madeleine entered a carriage, and was conducted first to the office of a notary, and then to the house of M. Pascal.
