Thank you for reminding me of my (non-bank) heist story which I totally forgot in the rush of trying to get the script done. It's about an art thief named Isabella Stewart Guggenheim and she steals various pieces of fine art compulsively but then isn't really interested in selling it (and couldn't really, because it's priceless and stolen and no museum would touch it) and she doesn't really have a place to display it properly and the upkeep costs are driving her crazy. And she decides the best thing to do is break back into the museums in order to put the art back, but she keeps stealing other art while she is there, compulsively, and she is really mad at herself, and they keep upgrading the security! Oh where will it end, Isabella Stewart Guggenheim? You have a hard life.
