Toby and Bethany were twins. Mrs D and Toby’s mum were twins. Mrs D killed Toby’s mum and Bethany “killed” Ali as revenge. Bethany died because she looked like Ali. I don’t think Toby is as innocent as we all think he is. Maybe HE killed Mrs D as revenge for Bethany cos he thinks she killed Bethany. -A didn’t kill Mrs D but finished the job by burying her. Always thought toby gave up on finding the truth about his mum’s death too easily.
