Dead Drop: A Black Desk Thriller. Black Desk, #2

When a dead service cabinet on an old harbor line shows signs of recent use, Paul Andrews knows he is not looking at forgotten infrastructure. He is looking at a route that was never supposed to wake again. As Paul and forensic investigator Anna Calder follow the line through service roads, storage yards, and paper-trail rooms built to look ordinary, they uncover a buried transfer system still moving under the surface of the present.
Someone has preserved it. Someone is using it. And someone inside Black Desk is already closing in. Dead Drop is a cold, procedural espionage thriller about hidden routes, buried contact lines, and the danger waiting at the far end.
