If you’d told me four months ago that I’d be lying on damp grass, clutching a bullet wound to the stomach, while next to me the love of my life lies dead from a bullet wound to the head, I’m not sure I would have believed you. If you’d told me I’d be surrounded by three other dead bodies, I definitely wouldn’t have believed you. And if you’d said it was all because of an argument over a metre of land, I would have thought you’d lost your mind. I might have even laughed.

But I know this woman so well and I can tell there’s a grain of truth in what she says. Which begs the questions: Who am I? Where did I come from? When I dig into the truth, I suddenly stir up a hornet’s nest of secrets, lies – and possibly a crime so unfathomable – that stretches back decades.

I don’t want the perfect marriage. I want revenge… If you had met me a year ago, you wouldn’t have noticed me.

Each morning, I arrive at the luxury Cedarwood Manor hotel, put on my crisp maid’s uniform and clean the rooms. I take great care in my work as I slip from one floor to the other. Most guests barely know my name. I’m invisible to them. That’s ok. I prefer people didn’t know my secrets.

I can’t believe that my steady, dependable father could do this to me. But a hush falls over my family as my ‘new sister’ Ava spills secrets about his hidden affairs and how he bought her silence. Now she’s finally free, she wants to be a part of the family.

I look at where the woman was sitting. There’s a scrap of paper tucked into the gap between the seats. With shaking hands, I pick it up. The note reads: Help me. At first glance, the couple on the train look normal. She’s dressed smartly, a floral patterned bag on her lap. But her hands are clenched, her fingers white. The man with her has his arm looped through hers, but not in a comforting way. He’s holding her too tightly.
