One could even take it further, there could be this one house in town that looks a bit less clean that the others, the shady kind of sorts, where an npc lives that deals in the more dark, non-legit aspect of the town. He could even have a machine in the basement for crafting counterfit coins.

Also, you wouldn't find him in his house for doing his illegal business, unless the sun was down. He'd only would want to do business when it's night, to avoid unwanted eyes, like a proper criminal ;)
