I cherished a most passionate love for a mistress, who had trusted herself to me, and whom I had loved for a long time. The count admits he never loved his wife, but was deeply devoted to his mistress Valerie. _Reveals the emotional foundation for the baby substitution._ > The idea of sharing my love with another was revolting to her. Valerie could not bear the thought of the count being with another woman. _Highlights Valerie's possessiveness and the count's complicity._ > I have preserved, as a monument of my folly, the letters which she wrote to me at that time. The count kept Valerie's letters as a reminder of his past mistakes. _Foreshadows the letters Noel brings as evidence._ > She died, sir, with this idea, which poisoned her last days. She died of sorrow; but saintlike, without a complaint, without a murmur, pardon upon her lips and in her heart. The count's wife died believing her son loved her, unaware of the substitution, and died forgivingly. _Emphasizes the tragic consequences of the count's deception._ > I have never seen her since. She wrote to me. I did not open her letters. She attempted to force her way into my presence, but in vain; my servants had orders that they dared not ignore. After discovering Valerie's infidelity, the count cut off all contact with her. _Shows the count's harsh reaction and the end of their relationship._ > I have perhaps sacrificed my own son to the child of an utter stranger. The count fears that Albert might not be his biological son, making his sacrifice even more tragic. _Reveals the count's deep doubt and regret._ > Albert, sir, has been the best of sons. Nevertheless, there has always been an icy barrier between us, which he was unable to explain. Despite Albert's goodness, the count maintained emotional distance due to his secret. _Illustrates the lasting damage of the deception._ > M. de Commarin was probably expecting some scene of this kind: for not a muscle of his face moved: he remained perfectly calm. Noel, on his side, was like a man who had received a blow on the head; he staggered, and was obliged to seek support from the back of a chair. The count remained stoic while Noel was visibly shocked when presented as father and son. _Highlights the emotional contrast and tension of their first meeting._ ## Links - HTML: https://www.betterreads.online/discover/the_lerouge_case_se/chapters/xi - Book: https://www.betterreads.online/discover/the_lerouge_case_se - All chapters: https://www.betterreads.online/discover/the_lerouge_case_se/chapters
