Walter: You're the only grandkid I've let in here. These are my most precious possessions.
Malcolm: Cool.
Walter: Oh, never mind that stuff. You don't want to waste your time with a bunch of guns. Take a look at this quartermasters' ledger books. This is where the war was really won. Take a look at this. Notice anything?
Malcolm: Oh, yeah. The numbers don't add up here.
Walter: What?
Malcolm: In that column. The numbers add up to 1,286 but the total at the bottom says 1,179.
Walter: I was just hoping you'd notice how the S's look like F's but this is incredible. I think this quartermaster was skimming rifles. This is the kind of thing that gets your name in the Civil War Quarterly. Good job, Malcolm! Let's see what else this guy was up to!
