When British spy Verity is captured by the Nazis in occupied France, she is forced to write down her secrets. She chooses to write about her best friend Maddie, a RAF pilot who flew the mission with her, pouring out her heart by flashing back to their joint history and detailing her current predicament. Not a moment goes by when we don't fear for Verity's life, but little do her interrogators know just how skilled Verity is in her spycraft. A thrilling, heartbreaking gem.
