@DjAlexDubCheck Here it is. It's more about how shrines and temples don't pay taxes on offerings and various other sources of income, but it starts off with the aforementioned heiress (and a possible murder with suicide, no less). When I think about it, it kinda makes sense that a Buddhist monk would be good at managing a business and earning money if he's from one of the bigger temples or shrines.
