I really like the story.
We all know that there are people like this, people who are willing to do everything to have what they want, this is a story like that, something based on facts that can happen to anyone, not exactly related to a childhood friend but it could be related in other personal aspects of your life.
You could be dating a murderer and you wouldn't even know it.
You should always keep in mind the saying "you will never fully know a person, not even the one you married." I think this story itself gives that message, out there there are very, very crazy people willing to do everything to get what they want
