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. She catches my eye and I see desperation there.

I’m opening my mouth to speak when the train grinds to a halt and the man stands, hauling her away. She looks at me again, then at the seat behind her, her face pale.

I find the message she left behind. Help me.

When I call the police, there’s no sign of the couple on CCTV. The kind detective gently suggests that it’s not surprising, with my history, that I am imagining things.

Wanting to save someone. I know what I saw.

If no one will believe me, I’ll find her myself. But as I search, what I find seems personal.

Little things that remind me of what happened ten years ago. And I think I’m being followed, that someone broke into my flat.

The hunt for the woman on the train is leading me somewhere I should never go. Can I save her, or will I be next?
