Mills: Just because the fucker's got a library card doesn't make him Yoda.
Somerset: How much money you got?
Mills: I got fifty, fifty bucks.
Somerset: I propose a field trip; Come on, we'll make a list. At the top, we’ll put "Purgatory," "Canterbury Tales," anything relating to the Seven Deadly Sins. Ask yourself-
Mills: Hey, wait, wait.
Somerset: What would he study to do the things he's done? What are his interests now? Jack the Ripper for instance?
Somerset: They must have had about fifty health violations during their last inspection.
Mills: Could you at least sit across from me? I don't want people thinkin’ we're dating.
Somerset: Give me your money.
Mills: I'm giving you this but if some stranger walks up they ought to know what the fuck we're doing. Fuck.
Man2: Hey, Somerset. How you doin’?
Somerset: OK.
Man: I didn't figure this was gonna be a menage a trois.
Somerset: It's not a problem. Sit down.
Man: Only for you do I do this. It's a big risk. I figure we're just fair and square.
Somerset: It's a deal.
Man: All right. About an hour.
Mills: Yeah, help yourself. Well, that was money well spent?
Somerset: Yeah. All right, by telling you this, I'm trusting you more than I trust most people.
Mills: Well, good, because I'm about ready to punch you.
Somerset: It's probably nothing but even it is, it's no skin off our teeth. The guy in the pizza parlor is a friend from the Bureau.
Mills: Who? Stinky man?
Somerset: See, for years, the FBI has been into the library system, keeping records.
Mills: Mhm. Assessing fines.
Somerset: No. Monitoring reading habits. Look, come on, certain books are flagged. Books on, say, nuclear weapons or "Mein Kampf." Anyone who checks out a flagged book has his library records fed into the FBI’s computers from then on.
Mills: Wait, wait, wait. How is this legal?
Somerset: Legal, illegal, these terms don't apply. You can't use the information directly. It's just a useful guide. It might sound silly, but he can't get a library card without an ID and a current phone number. See?
Mills: So they run a list.
Somerset: Precisely. If you want to know who's reading "Purgatory" and "Paradise Lost" and "Helter Skelter," the FBI's computers will tell us.
