"'The diligence is about to start, so I must bid you a hasty farewell, my dear Pierre. I have only time to address this letter and assure you once more of my devoted affection. "'HENRI DAVID.'" CHAPTER XVIII. As Madame Bastien returned the letter with a hand that trembled with emotion, Doctor Dufour said: "One word, please. I do not know what your decision may be, but before you announce it I ought to give you some information about Henri David, so you may know all about him before you either accept or refuse his offer. Do you not think so?" "No, my dear doctor, I do not," replied Madame Bastien, after a moment's reflection. "What?" "I shall be obliged to do one of two things, that is to say, I shall either have to accept or decline M. David's offer. If I accept it, a desire to know anything further in relation to him would show a distrust of him and of you. This letter is to my mind convincing proof of his high sense of honour and his generosity of heart. If, on the contrary, I cannot or should not accept M. David's offer, there would be a sort of indelicate curiosity on my part in encouraging your revelations concerning the past of a person who would remain a stranger to me, though the nobility of his offer merits my eternal gratitude." "I thank you both on David's behalf and my own for the confidence you manifest in us, my dear Madame Bastien. Now reflect, and let me know your decision as soon as your mind is fully made up. In compliance with my friend's request, I lost no time in acquainting you with the contents of his letter, and that is why I came at this late hour of the night, even at the risk of disturbing you, instead of waiting until to-morrow, and--" The doctor did not finish the sentence, for a shrill, spasmodic laugh resounded from Frederick's room, and made Madame Bastien spring from her seat. Pale and terrified, she seized the lamp and ran into her son's room, followed by the doctor. The unfortunate youth, with distorted features, livid complexion, and lips contracted in a sardonic smile, had been seized with a fit of delirium, due, doubtless, to a reaction after the events of the evening, and his frenzied outburst of laughter was followed by incoherent exclamations, in which the following recurred incessantly: "I missed him, but patience, patience!" These words, which were only too significant to Madame Bastien, showed how persistently the idea of vengeance still clung to Frederick. Thanks to Doctor Dufour's almost providential presence, the promptest and most efficacious attentions were lavished upon Frederick, and the physician spent the remainder of the night and the morning of the next day with the sick youth. Toward evening there was a decided change for the better in his condition. The delirium ceased, and it was with unusual effusiveness that the poor boy thanked his mother for her devotion, weeping freely the while.
