And then prominent crime boss Arthur Kelvin is found dead at a local beauty spot. Who killed him? Could it have been a member of his own gang? A rival, from within Dorset or further afield? Or maybe one of Kelvin's many victims? When Lesley starts to suspect that someone close to her might be involved, her world turns on its head. Can she solve the murder and keep her career, team and relationship intact?
