So I always thought that movie was fascinating because in that book in the early 70s, they're saying we have to even read the fiction novels about spies and spooks and commandos because sometimes they're written under a pseudonym by former spies. To avoid their non disclosure agreements that they sign when they leave CIA or other situations. And they're not supposed to talk about their former life. So they write a novel. And the novel has more information in it than if they wrote a paper and tried to publish it.
