When Zoe Walker sees her photo in the classifieds section of a London newspaper, she is determined to find out why it's there.
There's no explanation, no website: just a grainy image and a phone number.
She takes it home to her family, who are convinced it's just someone who looks like Zoe.
But the next day the advert shows a photo of a different woman, and another the day after that.
Is it a mistake?
Or is someone keeping track of every move they make...
I See You is an edge-of-your-seat, page-turning psychological thriller .
