I do try not to spend much time reading in the suspense genre.
I do like to explore evil characters in my books.
Much of what we do in life has a huge component of luck.
I don't consciously do anything to maintain a unique voice.
It's important, I think, for a writer of fiction to maintain an awareness of the pace and shape of the book as he's writing it. That is, he should be making an object, not chattering.
Contrary to what many writers imply about the process, nobody forces a writer to sell his work to the film industry.
