Halloween-style question: Are you familiar with the story of La Llorona/The Woman in White?
If you have Netflix, there's an awful Mexican movie called La Llorona, animated, about defeating her. Also, Supernatural (the series) talks about her, a different variation. in their pilot. It's also on Netflix.
Not that one. The only _The Woman in White_ story I know is a 1859 novel by Wilkie Collins, considered one of the first detective novels.
Sure just what I need. Another pissed off woman...
So did Grimm
It's a ghost story in North/Central America. Wikipedia version: en.m.wikipedia.org/wiki/La_Llorona
Basically, it's a woman who killed her children for a reason that changes, then haunts around where she subsequently kills herself, either kidnapping children or killing men.
I haven't seen it. But it's a very popular concept when ghost stories come up.
