" Mabel Rose Chen was a perfect daughter. She knew this because everybody said it.
...
The thing about being a perfect daughter was that nobody suspected you might not be so perfect. That maybe you were fascinated by the fact that you belonged to this powerful family, and maybe you weren't so great at violin or tennis or French, but you were very, very good at spying. "

― Jude Watson , Mission Titanic (The 39 Clues: Doublecross, #1)
