Instinctively he lept back as the librarian dropped from the ceiling landing on the ground with a cracking sound as her nobbed, blackened knees knocked together.

She looked confused. Her body looked like a corpse wearing a coat, both of which had been hung on a rack.

She started to walk forward, her face still confused, but her black reflective eyes looking right at him. Her eyes almost appeared to plead with him to help her, but her teeth and jaws were grinding back and forth. Her veins bulged as she walked toward him, her once freckled white skin tainted by and engulfed in veins that flushed from red to black. She was silent other than the grinding of her teeth and the cracking of her bones.

He started to move back in a panic. The librarian struggled toward him, as if half of her body wanted to move one way and the other half wanted to move another. Johnny wanted to believe that the woman was in there somewhere, struggling to gain control , but he couldn’t believe that. Her look of confusion had been replaced with a look of terrifying joy, a twisted grimace of happiness; happiness that she was going to eat him.
