I think that some books are more successful than others to certain readers. People who read my books for the humor, they're going to love one book. People who read my books for the mystery, they might not like that book quite as much.
Every now and then I have to teach directing. The thing about the theatre is that the most important thing you can do as a director is to make sure that everybody is in the same world - you have to create the world and make sure everyone buys into it.
