Blood Lines is a high-stakes military thriller that plunges two seasoned investigators into a web of espionage, terrorism, and political intrigue in modern-day Berlin.

In Blood Lines, Nelson DeMille and Alex DeMille reunite Special Agents Scott Brodie and Maggie Taylor for a tense investigation into the murder of fellow CID agent Harry Vance. Set against the backdrop of Berlin’s Arab refugee community and Cold War shadows, the novel explores the murky motives behind Vance’s death—initially blamed on Islamic terrorists but soon revealed to be part of a deeper, more sinister plot. As Brodie and Taylor navigate jurisdictional constraints and clash with both German and American authorities, they uncover layers of deception tied to neo-Nazi movements, U.S. intelligence secrets, and geopolitical unrest. With sharp banter, relentless pacing, and morally complex stakes, Blood Lines delivers a gripping sequel to The Deserter, blending action and psychological depth in equal measure.
