“There is nothing in these books to help us.” closing the book with a snap, Helga threw her head back, her knuckles white from how hard she was gripping the book. The poltergeist has bested her, she spent all day chasing him around, using every spell she knows but it didn’t even seem to faze him. He simply giggled and flied away. It was hard to concentrate in the class she was supposed to be teaching when half of her mind was trying to think of ways to kill an undead being. 

“I hope you’ve had more luck than me.”
