The Anonymous Rapist
What if there was a dangerous rapist loose in your area and you didn't know about it? Imagine somebody was raping women at their house, then threatening to come back and kill them if they told the police or their families about it (they wouldn't know who the guy was, but he would know a lot about them, thus the fear that he could come back later and hurt them could compel them to keep their mouths shut)?
Imagine even more so if someone was doing this to women in Hollywood or something. Imagine somebody tracking celebrities down and managing to break into their homes and coerce them into sex. Imagine that went on for years and years because no one being raped was saying anything (insert Weinstein jokes here)…
Sounds like a decent plot for a movie or something
