Louise Tume was just 18-years-old when she went missing in 2005. Today she would be well into her 30s but her sister has not heard from her since a mysterious phone call a year after she had been reported missing.
"Becky - it's me - I'm okay," Louise apparently said, before the line went dead. Her younger sister Rebecca had answered the call at her foster parents' home and she has been determined to find out the truth of what has happened to Louise ever since.
At the time of the phone call, Rebecca did not even know that 'perpetual runaway' Louise had been missing. After a difficult childhood they had been separated and placed into care.
