One of Us is Lying

One afternoon, five students at Bayview High walk into detention. Only, one never makes it out of that classroom alive. And according to investigators, his death wasn't an accident. He died on a Monday. But that Tuesday, he'd planned to post juicy reveals about all four of his high-profile classmates. Now, all four of them are suspects in his murder. Are they guilty? Or are they the perfect patsies for a killer who's still on the loose? They all have a motive. They all have something to hide. They all have a history with Simon. And one of them is definitely lying.
