There is no information provided on the changes Monsieur Noirtier made in his will, so a factual answer cannot be given.
Step-by-step explanation:
Monsieur Noirtier de Villefort: The father of Gérard de Villefort and grandfather of Valentine, Édouard (and, without knowing it, Benedetto). A committed anti-royalist. He is paralyzed and only able to communicate with his eyes, but retains his mental faculties and acts as protector to Valentine.
The change made in a will by a character named Monsieur Noirtier. However, based on the excerpts provided, there is no mention of Monsieur Noirtier or any specific alterations he made to his will. The provided texts include discussions about hypothetical situations, the workings of a detective named Dupin, and a confession of forgery, but nothing about Monsieur Noirtier's will. Therefore, without the relevant information, we cannot provide a factual answer regarding the changes Monsieur Noirtier made to his will.
