We don’t have the death penalty in the UK, and life very rarely means actual life unless the crime is particularly brutal or the perpetrator is so mentally ill they cannot be safely released. One thing I can tell you is that she isn’t dead. If she were found innocent she would have been released, and if she were found guilty she would have been sent to prison probably closer to home, which is why they are still in the wall when the prison is demolished. 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.
