The end of the Cold War made Lothar Taubmann a wealthy man, though his fortune came at the expense of the suffering and deaths of others. Given enough money, his conscience stays silent. And yet, he fears that one day his handler will decide he has outlived his usefulness, and has him killed with two shots to the back of the head. When two children are found dead in Poland, the case barely registers beyond a quickly forgotten police report. Katrina Mitchell, however, stumbles upon possible connection to an old case. What begins as a faint clue soon unravels into a web of spies and double agents that have infiltrated the FSB, the CIA, and even NATO itself, entangling rival agencies in a conspiracy orchestrated by a former Stasi agent. Meanwhile, in Ceuta, four young women begin their training to become Sisters. Izabel Butragueño is among them. But the rigid schedule imposed by the Elders may prove an obstacle to the pursuit of Justice, especially when clues demand time and patience to follow.
