Our 2012 Halloween Countdown continues: After a Halloween party, Anne and her friend went back to her new house for a peaceful, enjoyable evening of conversation, but they did not count on the intrusion of another voice... a voice both of unimaginable despair and diabolical evil. It was a Halloween of terror that Anne will never forget. This is Anne's story.

interesting story but it sounds like a prank that other kids or maybe even adults were playing on the children. It was their own house but they couldn’t find the source of the voice. Gives me some ideas!
I should also say when you get scared that every voice that sounds unusual will be perceived as evil.
The story is lacking in details. What was weird about the voice and what exactly did it say ?
