Here we are, squabbling over tuna fucking sandwiches and there she is – almond-shaped green eyes, snub nose, lopsided grin, the hint of a dimple in her cheek. ‘MISSING’ is stamped over her face in large black letters.

Make no mistake, my darling. I am coming for you. I will take you back.

Where I’m taking you, no one will ever find us. We’ll have all the time in the world for you to grow to love me as much as I love you.

It’s as if he’s trodden in my footsteps, seen what I’ve seen, felt what I’ve felt, as I’ve criss-crossed the moors countless times.

She shivers. ‘I can’t understand why anyone would want to live out there. You’d be totally isolated.’
 I do. I could imagine waking up each day and instead of looking out of the window and seeing the moor in the distance, you’d be in the heart of it, feeling the wind turn, the storm rage, the rain lash, hear the plovers piping.

Evie is our beautiful, dark-haired, green-eyed child,’ I say. I can hear the tremor in my voice. ‘Like many seven-year-old girls, she’s obsessed with princesses. We think she looks more like a fairy. She loves Lego and painting. She laughs easily. She has pretend tea parties in a tree in our garden and invites all her dolls. She wants to be an artist when she grows up. Please find her. Please bring her back to us. We miss her beyond measure. She is the love of our life.

I can’t believe I ever thought reading to her was a chore. I’d sit here some nights, fidgeting, thinking of all the things I needed to do, my voice hoarse, reluctant to read, ‘just one more chapter,’ wishing I could escape to my glass of wine. What did I have to do that was so important? What could be more important than reading my daughter a bedtime story?

She said that the mummy and the daddy took their daughter up onto the moor. They had a picnic. They’d brought all of her favourite food – cheese sandwiches on white bread with the crusts cut off and strawberry-pink cupcakes – and when the little girl had finished eating, she looked around for her mummy and the daddy. But they’d gone. They’d left Evelyn on the moor by herself.

I don’t believe he was deliberately taking indecent pictures, they’re too artistic; he’s managed to capture that magical moment when a child’s mind spins into a make-believe world. But actually, what Jack did is steal something – a child’s innocence – whilst creating something darker that will resonate with the adults looking at these photos: themes of sexuality and death, the leitmotifs that run through fairy tales, the stories that we tell ourselves about our children.
