"Draco, you will understand in time. I am sending you certain books with my next owl. For now, remember this: I come from the Black family, but no Black mother was ever less determined to protect her children than a Malfoy mother was. I will move mountains for you, Draco. You have only to speak the word, or have a certain look on your face. I have interpreted several such expressions already. Do not fear, my darling. You shall have what you need.
Your loving mother,
Narcissa Black Malfoy.”
