I'm not a bad person, but maybe I did a bad thing.... Life is good for Anna Wright. She's a successful media executive working for one of the UK's largest TV corporations. She's got a great boyfriend, some close friends and a lovely home. She adores her dog, Wispa, and she loves to run to help her destress. But Anna's perfect life starts to crumble from the moment when, out jogging on the Heath one day, she meets a handsome stranger.
You know that feeling. Your life's on track and all is going well. And then something monumental occurs that turns everything on its head. It happens to everyone, but, for Kristin Ryder, it was much, much worse.... When up-and-coming photographer Kristin begins to receive anonymous emails, her life in a trendy loft in London's Hoxton with Anton, her ultra-cool, street-artist boyfriend, suddenly begins to feel unsafe. The emails come with sinister attachments that suggest the sender has an intimate knowledge of Kristin's past, and soon her life spirals out of control.
