Fire most of the staff and sell the mansion. What else can she do? Maybe she could figure out what exactly is going on with those fake jewels, but if it's connected to her parents disappearing, chances are it's both impossible and useless to do anything about it. The mansion should be worth a lot, though. And she has got no money to pay wages to any maids and butlers, does she? I wonder what exactly she was going to do with a new loan. She didn't inherit any memories, so figuring out how to make profit in that city and world might require a bit of time and research. She hasn't got time.
