Now a Sunday Times top 20 bestseller 'A rival to Gone Girl for its addictive, twisted plot.' STYLIST Lexie's got the perfect life. And someone else wants it... Lexie loves her home. She feels safe and secure in it - and loved, thanks to her boyfriend Tom. But recently, something's not been quite right. A book out of place. A wardrobe door left open. A set of keys going missing... Tom thinks Lexie's going mad - but then, he's away more often than he's at home nowadays, so he wouldn't understand. Because Lexie isn't losing it. She knows there's someone out there watching her. And, deep down, she knows there's nothing she can do to make them stop... A compelling, heart-racing thriller that will have you looking over your shoulder long after you turn the last page. The perfect read for fans of Louise Candlish and Adele Parks.
