Watching You by Lisa Jewell

Where Watching You starts off and where it ends are in two completely different places, but you can be sure to feel the hair on your neck raised the whole time as you wonder "who is watching me?" A quaint street in Bristol where neighbors know each other (and watch each other obsessively, apparently) becomes the scene of a grizzly murder. We don't know who is dead, but the young Joey Mullen is a prime suspect due to her infatuation with the owner of the house, a married Tom Fitzwilliam, and the fact that the police found one of her boot tassels on scene. As we alternate between present day police interviews and scenes from the past few weeks as Joey and Tom get to know each other, the image of what might have happened starts to crystallize, until new details emerge and it gets all blurry again. This is truly one of those books that will leave you uncertain until the very end.
