Paul Avery: So Robert, what are your hobbies?
Robert Graysmith: Well, I like to read.
Paul Avery: Uh-huh.
Robert Graysmith: Uh, I enjoy books.
Paul Avery: Those are the same things.
Robert Graysmith: I've been thinking.
Paul Avery: Oh God, save us all.
Paul Avery: Well, it looks like the real Zodiac Killer... was friendship.
Paul Avery: What's your angle, here? This is good business for everyone but you.
Robert Graysmith: What do you mean, "angle"?
Paul Avery: Do you know more people die in the East Bay commute every three months than that idiot ever killed? He offed a few citizens, wrote a few letters, then faded into footnote... Not that I haven't been sitting here idly, waiting for you to drop by and reinvigorate my sense of purpose.
Paul Avery: Methinks our friend's a tad bit fuckered in the head.
