Lots of things resolve themselves just by being in the drawer a while.
You must get the servants to work for you. You mustn’t do all the work yourself. That is, you should ask other people for information, and steal ruthlessly from what they provide. None of the things you make up will be as hair-raising as the things people tell you. I can only encourage you to steal as much as you can. No one will ever notice. You should keep a notebook of tidbits, but don’t write down the attributions, and then after a couple of years you can come back to the notebook and treat the stuff as your own without guilt.
Writing is about discovering things hitherto unseen. Otherwise there’s no point to the process.
