Patricia Highsmith

I like to work for four or five hours a day. I aim for seven days a week.

I don't want to know movie directors. I don't want to be close to them. I don't want to interfere with their work. I don't want them to interfere with mine.

I was in New York. Hitchcock was in California. He rang me to make a report on his progress and said, I'm having trouble. I've just sacked my second screenwriter.
