Chapter 8: Discuss Marguerite's betrayal of the Marquis St. Cyr and his family, how she feels about it now, and the effect of the betrayal on her marriage.

Marguerite's betrayal of the family was thoughtless; she was angry at the family for St. Cyr's treatment of her brother and she repeated something she'd heard. What she did was the senseless act of a young woman, but it caused the execution of the entire family. Her betrayal caused an irrepairable breach to her marriage, and she was horrified at what she had done.
