One of Us Is Lying by Karen McManus tells the story of how deadly a rumor could end up. It started with an after school detention. Five kids walked in. Addy, Bronwyn, Nate, Cooper, and Simon all have detention. They don’t usually hang out, so they don’t talk very much. Simon has a gossip app called About That. He posts rumors about kids at the school on the app regularly. Simon gets up to get a glass of water and as soon as he finishes the water he starts having an allergic reaction and dies.
The main belief that the police had was that someone had poisoned Simon because of a rumor posted on the app. The police assume it was one of the four in detention with Simon. In the police investigation, they find peanut oil in the water. Now the four have to do their own detective work to find out who really killed Simon. At the time of Simon’s allergic reaction, the nurse had no EpiPens, and an EpiPen was later found in Nate’s locker. The police then took Nate to have him questioned. Bronwyn hears about this and realizes that their lockers were searched the morning of Simon’s death so somebody must have put the EpiPen there to frame Nate.
The three students keep looking for clues, and their search leads them to one of Simon’s only friends, Janae Vargas. They continually ask Janae if she knows anything until she finally tells them who killed Simon. She tells them that somebody made a plan to kill Simon by putting peanut oil in the water and that the person was…(spoiler warning! highlight text to read!): Simon himself. Simon planned every detail like hiding the nurse’s EpiPens and hiding one in Nate’s locker. Simon’s apparent motive was that everyone in the detention class had been rude to him so he decided to try and frame them
