Rosalind begins to think Olive is innocent of her crimes and visits Olive's solicitor who reveals Olive refused to see her father following her incarceration. Hawksley continues to believe that Olive is guilty and Rosalind realises he is still affected by the events from all those years before. Rosalind speaks to Olive's old work colleague Lily and discovers Olive had a boyfriend called Gary who may have a link to the murders. Gary's sister refuses to believe Gary had anything to do with them, but suggests a courier company was secretly delivering letters to Olive from a man matching the description of her father.
