The hunt for a ghost is about to begin.
When intelligence regarding a sensitive underwater measurement project is leaked, the Beidu City State Security Bureau moves with surgical precision. For Liu Jinwen, a seasoned agent returning from a volatile assignment in Europe, the case is an opportunity to prove her worth-and a trap she didn't see coming. As she deploys advanced mobile signal tracking and deep-dive social analysis, Liu uncovers a web of connections that stretches from the research labs of the 602 Institute to the international halls of MI6. In this world, a single error in a chat log or a misplaced signal can be the difference between a successful bust and a national catastrophe. Shadows is a sophisticated, gritty, and deeply researched counter-espionage thriller. It provides an authentic, unvarned window into the technical and psychological complexities of intelligence work in the heart of contemporary China.
