In 1933, after Hitler and the Nazi Party consolidated power in Germany, Immanuel Birnbaum, a German Jewish journalist based in Warsaw, is forbidden from writing for newspapers in his homeland. Six years later, just months before the German invasion of Poland that ignites World War II, Immanuel escapes to Sweden with his wife and two young sons. Living as a refugee in Stockholm, Immanuel continues to write, contributing articles to a liberal Swiss newspaper in Basel under the name Dr. B. He also begins working as an editor for the legendary German publisher S. Fischer Verlag. Gottfried Bermann Fischer had established an office in Stockholm to evade German censorship, publishing celebrated German writers such as Thomas Mann and Stefan Zweig. Immanuel also becomes entangled with British intelligence agents who produce and distribute anti-Nazi propaganda in Stockholm. On orders from Winston Churchill, the Allied spies plan several acts of sabotage. But when the Swedish postal service picks up a letter written in invisible ink, the plotters are exposed. The letter, long a mystery in military history accounts, was in fact written by Dr. B. But why would a Jew living in exile and targeted for death by the Nazis have wanted to tip them off? Daniel Birnbaum’s novel will intrigue readers with its fascinating portrayal of the astonishing connections and often mysterious players illuminated by his grandfather’s remarkable wartime life.
