Hello! I'm writing my second book and I have a question as I am not very familiar with the horror genre. My story is set in the Victorian era and the protagonist is hired as a governess in a big mansion. However, the family's intention is not for her to educate their kid, but to make her descent into madness as a part of a bigger scheme. How could they make this girl go insane? I have already thought about some examples, but any ideas are welcome! Thank you.
