‘I’m Mary,’ she says, looking up at me expectantly as if I should know exactly who she is. She’s wearing a fitted tunic dress with a starched white collar and short sleeves. But it’s her eyes—piercing, with something dangerous lurking behind the cobalt blue—that send a shiver down my spine.

She told me she was the housekeeper, and who was I to question? Our stay in this perfectly renovated Victorian house on the rich side of Hastings was a favour from an old school friend while the fire damage to our own little place was being fixed. This is not my house, and they are not my rules. So I step aside, and I let her in.

Am I paranoid to think that she’s watching my every move?

What am I supposed to do when she rests her head on my husband’s broad shoulder, a glint in her eye that only I can see?

Should I have packed my bags and left the moment I found her rooting through my belongings?

And when I return one day to find she’s moved into the spare room with her son, do I believe her when she says she has nowhere else to go? Do I trust her here, alone with my two little children?

Each night I lie awake wondering who this strange woman is, and what she wants. I hold my babies close as the lights flicker and songs from the childhood I spent a lifetime trying to forget blast through the speakers.

But when I finally uncover the secrets hidden in this house, my past crashes into my present. I realise I’m in more danger than I could possibly have imagined…
