But aren’t you angry that he snatched you from your family? I ask.

‘Part of me knows I should be,’ she concedes. ‘But no. I’m only sad that things ended the way they did. That Dad died. He shouldn’t have done. That shouldn’t have happened. He didn’t deserve that.

‘I often ask myself how things might have turned out if I hadn’t left. It might have been better if I hadn’t. I was happy, and well-cared for, and my dad would probably still be alive. Everything was fine for us, there’s no reason to believe that things would have changed that much.’

I ask if she’s heard of Stockholm Syndrome, and she rolls her eyes. ‘Yes. The therapists are always banging on about that too. They’re wrong. It’s patronizing. They didn’t know Dad and me. How we were. I don’t have Stockholm Syndrome and I never did.

‘As a child, I didn’t know any other parent. Dad took good care of me. Of course I was going to love him like a father. Anyone would, however they came to be there. It’s not rocket science.’

But does she not feel she missed out on her childhood? School? Friends?

‘I might have been sheltered,’ she says, becoming more defensive, ‘but I had a very happy childhood, with everything I needed. Dad saw to it that I was well educated. He had me read at least a book a week. I’m good at maths. I learned where all the countries are. History. All the prime ministers. Kings and queens. Practical things too. How to care for animals. Grow vegetables. Wire a plug. He absolutely wanted the best for me. And if things hadn’t … turned out the way they had, I’d have gone on to live a normal life like anyone else. I’m sure of it.’

While Anna’s new name and image remain officially protected, this hasn’t stopped certain websites reporting on her antics. I ask about the reports that she is, these days, something of a wild child.

She flicks her hair. ‘I go to a lot of parties,’ she says. ‘And it’s no secret among my friends that I like a drink. It’s one of the many causes of friction between me and, uh, Karen. Then there was that time when I had to go to hospital to have my stomach pumped. She got really upset about that. But if she was less restrictive about what I can and can’t do then …’ she trails off.

How about her other family members? How does she get on with her brother? She visibly brightens. ‘He’s great. I adore him. We spend a lot of time together. He can be a bit overprotective sometimes, but apart from that, we get on really, really well. He respects me and he always has my back.’
