Spring 1973. As the Cold War tightens its grip on Europe, a secret alliance is forged between East Germany's STASI and O.D.E.S.S.A., the underground Nazi network working toward the resurrection of a Fourth Reich. Orchestrated in the shadows by the KGB, the plan is bold and deadly: a coordinated attack on Israel from both outside and within-carried out by Arab armies, backed by Soviet support, and fueled by weapons trafficked through neo-Nazi operatives.In East Berlin, behind the crumbling façade of a fading dictatorship, Rita Ritter-a Jewish antiques dealer and the longtime lover of a senior STASI officer-uncovers the conspiracy. Haunted by her childhood in a concentration camp and disillusioned by the regime's lies, she risks everything to reach Mossad, offering explosive intelligence in exchange for safe passage to the West.The mission falls to Leonard Walder, a former Israeli agent now living a quiet life as an antiques dealer in West Germany. Under the pretense of attending a rare book and art fair in East Berlin, Walder makes contact with Rita-and what he learns threatens to shake the fragile balance of the Middle East.What follows is a tense, high-risk operation to extract her from deep within the DDR, across one of the most heavily guarded borders in the world. With help from the CIA, a professional smuggler, and old Cold War tradecraft, Walder is drawn back into a world he thought he'd left behind-where the ghosts of Nazism, Soviet ambition, and Israeli survival intersect.Set against a vividly recreated 1970s backdrop-from Hitler's Eagle's Nest in Obersalzberg to the shadowed squares of East Berlin, from Budapest to Bonn-Codename Obersalzberg blends historical accuracy with gripping espionage to deliver a thriller steeped in paranoia, betrayal, and the lingering shadows of World War II.
