One of us is lying

Five students walk into detention at Bayview High, but only four come out alive. Simon, the creator of the school’s famous gossip app, dies suddenly during the hour, and investigators say it wasn’t an accident. The four remaining students—the brain, the beauty, the criminal, and the athlete—all have dark secrets they wanted to keep quiet. To prove they are innocent, they must work together to find the real killer before their own secrets are shared with the whole school. It is an exciting mystery that shows how everyone has something to hide.
