Gosh, you have some good points.
Jeffrey was into blackmailing...no reason why she wouldn’t be. Once you have no leverage your of no use. She has something or she wouldn’t be still alive.
If she was a danger she would already be dead. She has something...or someone’s. I wouldn’t be surprised about a deadmans switch.
We tend to think of Epstein as the prize,but he was not the head of the operation.
Ghislaine was.
