I had this dream where I was a detective and I was looking for a serial killer. This killer posted on his twitter clues, like riddles. Where he would be, where he would be hunting, where his latest victim would be found.
Like Zodiac, but high tech, taunting us. Telling the world that he's right here, but no one will ever find him.
Don't ask me how his IP is not traced, I'm not a techy.
