YOU THINK YOU KNOW ME... My name is Lucy. At twenty-seven, I'm too young to be a widow. I'm trying my best to start over though: new city, new job running my own little shop. I try to fade into the background where I can, but the police won't let me disappear completely. There are too many unanswered questions about the night my husband died. YOU THINK YOU'VE HEARD MY STORY BEFORE... I even have a new lodger, Elizabeth. She's friendly, but definitely not a friend. Beautiful, too - tall and slim with the sort of swishy blonde hair I've always coveted. But then, I covet everything about her. Her high-powered job, her friends and her confidence. I'd give anything to be her. BUT YOU'RE SO, SO WRONG. If I were to tell you what happened to us next, how our lives would become inextricably linked, you wouldn't believe me. You might believe Elizabeth - she's good at making people trust her... until it's too late. She's keeping some very dark secrets, darker even than my own. And to have a chance of surviving them, I'm going to have to fight not only for myself but for Elizabeth too. This is not the story you think it is. You'll see... A tense, gripping psychological thriller for anyone who raced through The Girl Before , Behind Her Eyes , or The Girl on the Train .
