A Clown's Finale

From the introduction: 'No, I don't like traveling performers,' the large elf, clad in plate armor, stated. Without giving a chance to respond, disgust clear on his face, he continued: 'Even when they aren't crooks themselves, they attract them like flies. I want this resolved so they move on, but they won't talk to us. You're more their type, perhaps you can get something from them.' Aramil will offer the party 1000 gp to help resolve whatever grievance has occurred that is making the circus stay in town. Crime, specifically theft, has risen since the circus came. While his disdain for adventurers is clear, the guard has been getting overwhelmed. Also, in an attempt to run the circus out for the foreseeable future, he offers an additional 500 gp if the party can find evidence linking a recent outbreak of cholera to it.
