The Man in Black

Well, this is my first post. Today, I'm going to talk about the man in black from Book 9 of The 39 Clues. In the book, it is revealed that he is actually Fiske Cahill, Grace's brother. When he was young, he ran away, and kept in touch only with Grace. Then, in Book 9, he revealed himself to Dan and Amy. Also, like Amy is like Grace, Dan is like Fiske.
