Early date- Part 3

Though one thing which bothered her was that...Lady Isabelle was a white witch who was not allowed to kill people but she had touched upon the forbidden magic. She could have protected herself somehow. For a woman who wrote the whole book of spells, Penny was sure Lady Isabelle knew how to make use of every single one of them yet she hadn't used it. 

Why?

The question had appeared before in her mind, she was figuring it out that time and she was doing it right now too. Did the woman think dying was better, or was there some greater cause that she had given up her life? Now that she had come across the portraits in Delcorv's mansion, she could tell that the woman they had met in the church was almost the same woman who was in the many paintings that hung on the wall. 

If there was a slight possibility that they were indeed the same person, she wondered why a remarkable woman like her had never come to meet her son again. Her heart ached for both of them.
