The vampires have always been metaphors for me. They've always been vehicles through which I can express things I have felt very, very deeply.
The whole theme of Interview with the Vampire was Louis's quest for meaning in a godless world. He searched to find the oldest existing immortal simply to ask, What is the meaning of what we are?
Memnoch the Devil happen to be my favorite of all The Vampire Chronicles.
The most difficult novel I have had to write in terms of just getting it done was The Vampire Lestat. It took a year to write.
