She has admitted that tales of sexual abuse in her novels are based on her own experience, despite denying this in the past.
"It has taken me 49 years to talk about it," she told the Mail on Sunday, "It has been slowly coming out and each time I say the words it gets a bit easier."
"My childhood was stolen from me. I was not an innocent girl enjoying things in the way other children were. From a young age I was made to be different and ashamed.
"Even now, I fear that people will say it was me and that I must have done something wrong; that there was bad in me that made other men do that; that I was a child harlot.
"It happened more than once so what was it about me?"
Anglican vicar Revd James Cameron, now deceased, is the man accused of abusing the MP at St Mary's Anglican Church in Halewood.
She said it started when she was asked to go to the vicarage to view a stamp collection.
"But he moved from stamps to showing me a Playboy magazine, and then black-and- white pictures of him and his wife having sex," she said.
"'I didn't know what sex was - I was only nine. But I remember thinking it was bad and wrong and I felt filled with shame. He told me he'd set up a camera in their bedroom.
"He asked me, "How does that make you feel in your tummy?" He said people would think badly of me if I told them about the pictures and that no one would want to talk to me."
She told the newspaper there were many incidents but some she remembered more vividly than others.
"It's important to remember that my books are mostly fiction. But I did leave a trail of real events throughout them that I wanted the vicar to read.
"There was a delicious moment of triumph in writing his full name, just once, in the last book as I thought of him spending the rest of his life in fear. I wanted him to suffer. That was my private justice.
"That's not a good or positive emotion and certainly not a Christian one. I'm not suggesting everybody does what I did, but, mentally, there was no other avenue for me."
