A new novel invites us to fast forward four years. State surveillance is everywhere in Aotearoa, and if you dare to search for evidence of government corruption you could end up on the Kill List. That's the premise for Tina Clough's new thriller, The Shadow Broker. When Minnie finds a burner phone and starts to read suspicious coded messages, she turns to her friend Rumble to help her to make sense of them. Lynn Freeman asks Tina why she set the story just four years in the future, and how scarily prescient the plot seems to be.
