The problem with being a notorious outlaw is everyone likes to pin every crime that crops up on you. That includes lying, embezzling, murdering bankers. Which is fine if you're trying to become a notorious legend but a problem if you're hoping for a pardon for your past crimes. So Heyes and Curry have to set things to right. And there's nothing like a diamond field to get a crooked banker into a even bigger mess so that he has to confess to avoid a noose.
