'I need you to say that I was with you.' For thirty years, best friends Steph and Pip have been through thick and thin. There's nothing they would not do for one another. Until these simple words change everything. Steph, eternally solid and dependable, is begging her friend to lie to the police as she's desperately trying to conceal not one but two scandalous secrets to protect her family. Pip, self-consigned to the role of scatty hot-head, is overwhelmed; she's normally the one asking for help in a crisis. It's a big ask. So what would you do? How far would you go for your best friend?
