Goosebumps Book 44 Say Cheese And Die Again

Sourball, that's what Greg calls his English teacher, Mr. Saur. He just gave Greg a big fat F on his oral report. He didn't believe Greg's story about the camera Greg found last summer. About the pictures it took and all those evil things that happened. Poor Greg, he just wanted to prove old Sourball wrong, but now that he's dug up the camera, really bad things are happening just like the first time.
