Mum, your heart is the same size as your fist,’ she told me once in delight, and we both made our hands into fists and held them against our chests and bumped them together: hands as hearts.

They stole you from me. They took you away for seven years. Your entire lifetime. A life sentence. The waiting has been endless. The watching. The planning. Now, finally, I’m almost ready. I’ve got a few things to take care of and then we can be reunited.

Hello my darling, I’m your real father. I’ve been searching for you ever since you were stolen from me. I love you so much. Daddy

It’s quiet in the suburbs. It’s too cold for people to be in their gardens; and it’s not a thoroughfare so few cars drive by. I look past decaying roses and through the first flush of Michelmas daisies, blazing a glorious purple, into the darkened windows of the houses we walk by. Who lives here? Are they watching us? Did one of our neighbours do something seven years ago that he now regrets? How little we know of the people who surround us.

I think about the story I always tell her – of the kind lady who gave her to us. I suppose that must be how she imagines her father – as a kind man who gave her away too, as if she were a gift. Only now he wants her back.

My husband hands me my glass, full to the brim with green-gold wine and I stifle my resentment and attempt to smile at him. I mustn’t lose sight of what we have – two beautiful children; an amazing house that I never, in a million years, thought we’d be able to afford; Gill and Andy, my best friends – and this perfect day. I take a deep breath and feel my shoulders relax. I can smell the faintest trace of heather, drifting down from the moor.

The moor has always been part of my life. It’s like a muse: the colours of the heather and the sky; how you can see the savagery of the wind in the way the dwarf pine trees are bent double, the bleak lines of the landscape in winter when everything save the moss and the grass are dead, stones like bones, poking through a thin skin of bilberry bushes, rushes reflected in black bog water.

The dark edge of the moor and the Cow and Calf rock are crisp against the blue-black sky. I can’t see anyone outside, watching us. As I shut the door behind me, I hear a noise. It came from the hall. I feel the hairs rise on the back of my neck.
