My favorite part of the movie is when Jackie kept showing up to the different places linnet and Simon went to because it was setting up the movie for something bad to happen and made me feel like she was the killer but then made me doubt myself when she had an alibi, it did match up to the novel she did show up to all the places linnet and Simon went to while I was reading kept wondering if she was going to be the killer but once she had an alibi I kept trying to guess who it was.
