Dressed to kill

Martha knew there was something evil about the house she was moving into. It was so cold...and creepy. And it wasn't just the house that was giving her a weird feeling. Martha was sure someone was following her...watching her every move.
Then the practical jokes began — the scarecrow with a carving knife in its head, the fire. And the phone calls: "Trick or treat, Martha...you're dead."
It was October, but these were no Halloween tricks. Someone would be coming home this year with more than just a bag of treats. And Martha was the prize.
Trick or treat.
