This didn’t really do it for me.
I think the real culprit was obvious pretty much from the get go. A wee bit of a psycho vibe going on there. A tiny niggle here and there was later confirmed.
Jack makes it hard for for Sarah to trust him. She has no idea about his past, the murder in his family or his past liaison with his brother’s wife.
Sarah feels boxed into a tiny corner by the events in her husband’s home-town. Who can be trusted? Is there anyone on her side? Is Jack just playing some kind of sick game with her life and that of her children.
Suddenly the man she has loved for many years is not only a stranger, but also a potential multiple killer. On top of that Jack seems to be really cosy with his ex. Talk about making someone look like a complete fool. I think I would be slightly angry and overly cautious too under those circumstances.
From the very beginning Jack and Sarah appear to be complete strangers, despite the fact they have been married for a few decades and have two children. Perhaps that is what makes everything seem so disconnected. Baring that the characters might just have lacked depth.
Overall it felt a bit messy, but it was an ok read.
