‘But this never happened to you,’ she suggests.

‘In my first marriage,’ I say quietly, ‘I knew that my husband would not have a child. But I had to let myself know that I was different from him. I longed for a baby, and I wanted to be loved.’

‘Did you wish for it?’ she asks. ‘Did you make a spell to make him change?’

‘I didn’t try to change him, but I had to know the sorrow of what was missing in my life. I had to find the courage to know that I had made the mistake of marrying a man who would not love me for myself, and who would not give me a child, and once I knew that, truly knew that I was an unloved maid – though a married woman – then I could wish that someone loved me.’

‘And you wished for Father.’

I smile at her. ‘And for you.’

She blushes in pleasure. ‘Is this magic?’

‘In a way. Magic is the act of making a wish come about. Like praying, like plotting, like herbs, like exerting your will on the world, making something happen.’

‘Will you teach me?’ she asks.

I look at her consideringly. She is a daughter of our house and perhaps the most beautiful girl we have ever had. She has the inheritance of Melusina and the gift of Sight. One of my children must inherit the cards my great-aunt gave me and the bracelet of charms – I think I always knew that it would be Elizabeth, the child born of desire, of the herbs, and my wish. And as my great-aunt Jehanne said: it should be the oldest girl.

‘Yes,’ I say. ‘These are not the times, and these are forbidden skills; but I will teach you, Elizabeth.’

Over the next few weeks I show her the bracelet of charms and the cards and I teach her about herbs that she will not find in Lady Elizabeth Grey’s still room. I take all the older children out on one frosty day and teach them how to find water in underground springs by holding a peeled wand in their hands and feeling it turn in their palms. They laugh with delight as we find a spring in the water meadow, and a dirty old drain from the stable yard.

I show Elizabeth how to open a page of her Bible and then think and pray over the text that comes to her. I give her a frwater pearl on a little cord and teach her how to watch it swing in answer to a question. And more importantly than anything else I start to teach her how to clear her mind, how to know her desires, how to judge herself; putting aside favour and indulgence. ‘The alchemists always say you have to be pure. You are the first ingredient,’ I tell her. ‘You have to be clean.’

When the time comes for her to go back to Groby Hall she tells me that the young man of the house, John Grey, is a most handsome young man, kind and beautifully mannered, and that she wishes he would see her for herself, and not just as a girl being educated by his mother, one of three or four young women that Lady Grey has in her keeping.
