Beth's debut novel is The Witchfinder's Sister, out with Viking in the UK and Ballantine in the US in Spring 2017.

It has been waiting in the dark, Matthew’s history – our history.

Now I must turn over the stone: that you might see it, wriggling to escape

1645. When Alice Hopkins’s husband dies in a tragic accident, she returns to the small Essex town of Manningtree, where her brother Matthew still lives.

But home is no longer a place of safety. Matthew has changed, and there are rumours spreading through the town: whispers of witchcraft, and of a great book, in which he is gathering women’s names.

To what lengths will Matthew’s obsession drive him?

And what choice will Alice make when she finds herself at the very heart of his plan?
