She saved my life. I faked her death…

I only came back home to lie low and reconnect with my sister Bryony. Her life with her gorgeous husband Alex is perfect – a far cry from the disaster mine has turned into…

But almost immediately I can tell something is wrong. My once bubbly sister’s skin is pale, her hair dull, her eyes unfocussed. She tells me Alex has turned obsessive, controlling her every move. A tear tracks down her cheek as I stare at her in horror.

‘I have to fake my death,’ she whispers and I jolt back in shock. ‘And I need your help to do it.’ As I start to shake my head, mouth trembling, she lays her winning card down: ‘You owe me, Jess. I saved your life.’

But after she’s successfully disappeared, I realise there are holes in her story – things she’s told me about Alex that can’t be true. Threatening messages that can’t have come from him. Rumours in the village about the way she’s been acting. She doesn’t contact me like she promised – and rather than being angry she’s gone, Alex seems completely devastated…

Have I just saved my sister, or helped her get away with something terrible? And when the truth comes out, will I be the one whose life is in danger…?
