One of Us is Lying is a suspenseful book with twists and turns that keep you guessing until the end of the novel. But if you are feeling a bit confused about the ending and need some clarification, or you just want some cheeky spoilers then you’ve come to the right place. I have also written an ending explanation of One of Us Is Next for those interested!
Ending Explained: The whole situation started when Simon, the creator of the high school gossip app, dies after apparently being poisoned during a detention he attended with four others and a teacher. These four students who were with him in detention were potential suspects in murdering him (Bronwyn, Nate, Addy, and Cooper). Not satisfied with killing Simon, whoever was behind the poisoning appears to have started sending out people’s deepest secrets to the student population. It begins to look like Nate (the bad boy with a history) is behind it all, however it turns out that Simon was behind it all as he arranged his own death by poisoning and left instructions to Addy’s boyfriend Jake to send out people’s secrets. Simon always felt like an outcast so the entire thing was what he thought was an act of revenge. He wanted to fool everybody and left instructions noting that he was behind the whole thing to a classmate. He wanted this note to be given out after fooling everyone. To him this was the comeuppance that everybody deserved, however it did not work out that way. The four students managed to work it out before it was too late and Nate was released.
