Chapters 11-12

In these two chapters, David and the others tell Petra about her telepathic ability to keep her out of suspicion. I wonder if Petra realized she could communicate this way before David told her. Soon after that, David learns that Sally and Katherine have been captured. Then, David, Rosalind, and Petra escape to prevent captivity themselves. They leave just in time. I think the protection of Petra has significance to the upcoming chapters, and predicts that she will have an important role. Her gift of telepathy has saved her from all dangerous situations, including her falling in the river and her encounter with a creature while riding her pony. Also, in these chapters we learn that Uncle Axel is the one who killed Alan, Anne's husband. This doesn't surprise me because he was the one who knew the most out of everyone and had a reason to kill him.
