(view spoiler)[I'm so glad I'm not the only one that was confused with this ending. So ultimately, the consensus is that Isra was taking the kids on the train, Adam was on the train and he killed her. How did he know she was on that train? Where did he kill her? I'm remembering something with a brick to the head? (hide spoiler)]
Michelle Henderson It was just a case of bad luck/timing. The last chapter was Isra's account of her taking the girls and leaving, and Adam happened to catch them. That is not in the final chapter, but we know this from Deya's memory in an earlier chapter when she's talking to Sarah. According to the newspaper article, he killed her when he beat her in their basement.
