I Know You Did It cover best.jpg

On her first day at a new school, Ruby finds a note attached to her locker saying I KNOW YOU DID IT. She's terrified that someone has found out she was responsible for the death of a girl called Hannah in a playground when they were both little, something which has haunted her since. When first one, then two, students are found dead, it looks as if Ruby is being framed by another killer. Or, she might be next.
