The music teacher, who Lisa had first met as a pre-teen at school in Australia, began by lavishing attention on the young girl.
Lisa, now a therapist and life coach, said: "Just before my 15th birthday, he started to send me threats that he was going to kill himself if I didn't go to England straight away.
And it wasn't just Lisa that the man was grooming - but also her parents, who were British but had emigrated to Australia when Lisa was two.
Fortunately, Lisa, who by this stage was 20, still had some remaining contact with her family back in Australia - one of the terms of the original deal.
Lisa Turner, now 56, described how the abuser lied to her parents and manipulated her into sex throughout her teenage years.
