Chapter 9 and 10

In chapter 9 petra falls into the water and uses her telecommunication to ask for help. David and Rosalind race there to help her, they find her unconscious but she is still ok. Anne announces that she is going to marry Alan. Uncle axel despises of this marriage and suggests that the kill Anne. But no one else had the same feelings as him about the marriage. I found these 2 chapters very intense!
