As D-Day approaches, an American spy is unmasked by Himmler's Gestapo and must flee the Nazis, in this novel in the Pulitzer Prize–winning historical saga.

In 1943, the once-unstoppable Nazi war machine is starting to falter. For a decade and a half, Lanny Budd's cover as a fine-art dealer and Fascist sympathizer has held firm, earning him the confidence of Hermann Göring and other top officials, including Adolf Hitler himself. With the Allies preparing to retake Europe, Lanny must make certain that the location of the invasion remains hidden from the Nazi high command. But his mission is compromised and his life endangered when Heinrich Himmler, Hitler's feared Gestapo chief, uncovers Lanny's true loyalties.

Now FDR's most trusted spy must run for his life, escaping into the European countryside with Hitler's executioners on his trail. His survival will require great courage, endurance, and ingenuity, but Lanny Budd is determined to live long enough to witness what he has waited so many years to see: the final collapse of the Third Reich.

One Clear Call is the thrilling ninth installment of Upton Sinclair's Pulitzer Prize–winning dramatization of twentieth-century world history. An astonishing mix of adventure, romance, and political intrigue, the Lanny Budd Novels are a testament to the breathtaking scope of the author's vision and his singular talents as a storyteller.
