You just made me think: I’m sure she gets part of his royalties. She just gave herself a big cut in pay.
If her accusations are true, she may have faced even larger cuts in pay if she said that he had raped her when she was a child/minor because she would be accusing him of rape. Wouldn’t her mother be in charge of his estate and move to sue her - seize the royalties of the book since McKenzie can’t prove what happened to her when she was, say, 11, and her own mother would be the only witness? I suspect that the charges are true and that the perv had been assaulting her when she was younger and her mother doesn’t want people to wonder why she didn’t intervene and her mother doesn’t want the cut in pay either.
