The Final Revival of Opal & Nev by Dawnie Walton:
You could see the gleam in her eyes while she told me the things she had done, the fornicating and so on, and wasn’t nobody but the devil and his minions who put it there. Drove her to whack off the perfectly good hair she had left on her head, tempted her into committing sins with married men… Well, it was a struggle, especially with her ankle in that cast, but I managed to get her down on her knees, yes I did!
As you can imagine, this was quite terrifying but also fascinating to witness. The Exorcist was still years away, understand.
