Truth truth lie

Everyone here has killed someone. There is no way off this island. You will all either kill or be killed here. One of these statements is a lie. But which one? Amira's less than thrilled to be spending the weekend with her husband's university friends. Two of them are hosting a joint 40th on a private Scottish island, with vintage champagne, expensive gifts, and soaks in the wood-fired hot tub. Despite the luxury, Amira knows she's going to feel left out, not to mention freezing cold and cut off. When they decide to play 'two truths and a lie', anonymously posting three statements about themselves into a box, years of resentment start bubbling to the surface. And then an extra slip of paper emerges, scrawled with three chilling threats. Who wrote it? And are two of the statements really true - have they all been responsible for someone's death?
