Book excerpt: It's 1944, and the quaint Midwest farm town of Russell, Kansas, hides a secret that could turn the tide for Hitler and the Third Reich in Europe. Nazi spies Andreas and Peter Othmer find it easy to blend in with the small community of 2nd- and 3rd-generation German-American Kansans. Hand-selected by Germany's military intelligence service, they're tasked with secretly documenting B-29 flight patterns from nearby Walker Air Force Base. But as the Allies advance eastward across Europe, the Nazi regime collapses--and with it the brothers' relationship, leading to a shocking truth concealed by the town's most powerful man with strong ties to the White House. Decades after the war, the long-buried secret begins to emerge. Two lifelong friends race to piece together the remaining clues, desperate to expose the dark truth before it's too late.
