Either way, whether she was convicted or found innocent, she would not have been able to get back to retrieve the letters. What I don’t know is the verdict – that’s really up to you to decide. Essentially she takes the fall for Ellie.

So instead of sending the letters she hides the whole package in the wall and goes to her trial with her original lawyer, relying on her original story to save her. Consequently she realises that she cannot make good on her promise to Mr Wrexham to tell the whole truth – at least not without betraying her sister’s trust. What you are supposed to know is what you probably already figured out – that Rowan / Rachel was writing to Mr Wrexham when she received the letter from Ellie and learned the truth about what went down at Heatherbrae House.

When the construction worker writes that the letters found in Rachel's former cell do not matter anymore, what does he mean? It is so frustrating to be left hanging like this. Ruth Ware should at least have let us know what happened to Rachel. Maddie put the pillow in the bed so that she could sneak up to the attic. How many kids could pull off such a complicated scheme? If you are willing to accept this premise, then it can be argued that Maddie was angry at all the nannies that she viewed as a potential threat to her family. Think of all the planning that it took to mess with the nanny's head.

Maddie was acting out to an extent that is not believable in an eight-year-old.
