I have really enjoyed other Ruth Ware books, but I think this one is my favorite of those I have read. A nanny is in jail for a crime she says she didn’t commit. And she’s writing to a lawyer to tell her story to convince him to help her get out. I really liked the multiple reveals in this one. I did think the ending was a bit confusing with the letters and the clarification of who got which letter. BUT, the interesting story and twist and turns kept me intrigued and on the edge of my seat waiting to hear what would happen next.
