"Isolation, solitude, secret plotting. A novel is a secret a writer may keep for years before he lets it out of his room. Writers in hiding, writers in prison. Sometimes their secrets turn out to be dangerous to the state machine. For most writers in the West of course this danger is extremely remote. The cells we live in are strictly personal constructions. Let's change the room slightly and imagine another kind of apartness. The outsider who builds a plot around his desperation. A self-watcher, a lonely young man, living in a fiction he hasn't bothered to put down on paper. But this doesn't mean he is unorganized, he organizes everything. This is how he keeps from disappearing. His head is filled with dangerous secrets, and he may finally devise a way to come out of his room. He invents a false name, orders a gun though the mail, then looks around for someone famous he can shoot."
