A body in Berlin. A conspiracy where all sides are dirty, and the clean up will be murder.

From New York Times bestselling authors Nelson DeMille and Alex DeMille, Blood Lines features the return of Special Agents Brodie and Taylor who are on the hunt for the cold-blooded murderer of a fellow agent.

Army Criminal Investigation Agents Scott Brodie and Maggie Taylor are tasked with investigating the murder of CID Special Agent Harry Vance, an accomplished counterterrorism agent whose body was discovered in a city park in the heart of Berlin's Arab refugee community.

The authorities suspect this is an act of Islamic terrorism, but Brodie and Taylor soon believe there is more to this case. In looking into Vance's movements, they delve into the many conflicts and contradictions of modern Germany, from the dark legacy of the Cold War to a rising neo-Nazi movement. Meanwhile, a new threat emerges from American intelligence agents who fear the duo might have learned too much about US clandestine operations during their previous mission in Venezuela.

Ultimately, Brodie and Taylor realize that the murder of Harry Vance was merely the prelude to a much more sinister future event - unless they can unravel the mystery in time to stop it.
