Killing Mr. Griffin by Lois Duncan
There was this teacher, see, who everyone hated because he actually, like, made you earn your grades. So like, these four kids decided to pull this prank on this teacher to get back at him for all the crap he put them through. It was a great idea, see, they were going to blindfold him and tie him up so that he would think he was being kidnapped, but like, they would just scare him, then let him go. Only they didn’t know Mr. Griffin had a weak heart. And that he took medication for it. So like, they were really screwed when Mr. Griffin kind of, well, died. Now four friends have a terrible secret and a body to hide. Ever tried to keep a secret in high school? It’s pretty much impossible, and pretty soon, somebody’s going to find out about Mr. Griffin. This nail biter was written before most of you reading this were born. But it still has the power to make your heart pound and bring your most hated teacher a bright, shiny apple.
