By the spring of 1931, a conspiracy is underway in Germany to assassinate President Hindenburg and restore the Kaiser's son to the throne, threatening the peace of Europe. At the behest of her godfather, Winston Churchill, the adventurous journalist Mattie McGary, a rising star in William Randolph Hearst's press empire, and her lover, Bourke Cockran, Jr., a New York law school professor and former army counterintelligence agent, get involved.
Today a forgotten figure, Bourke Cockran was acclaimed during his lifetime as America's greatest orator. He was also the lover of Jenny Churchill - Winston's mother - after the death of Lord Randolph. And, for 12 years (1895 to 1906), he was young Winston's mentor. Until now, the story of the extraordinary and crucial relationship between them has not been told.
In the summer of 1929, Weimar Germany's secret military agreement in the 1920s with the USSR to evade the Versailles Treaty and develop new weapon systems beyond the Ural Mountains is about to bear fruit. Aided by a shadowy international conspiracy of arms dealers, industrialists, and financiers, both countries are poised to dismember the newly independent Poland created in the aftermath of the Great War. To distract Britain from helping the Poles and risking a new world war, the conspiracy intends to foment a coup d'etat in the Irish Free State.
A string of strange deaths in 1932 leads Bourke Cockran, Jr., and his lover Mattie McGary to uncover a plot by Nazi scientists to conduct lethal experiments on American twins in order to create a master race. They confront an international conspiracy connecting Wall Street to Washington, DC; from Long Island's fabled Gold Coast to the marble corridors of the Barlow Palace in Munich, headquarters of the fast-rising Nazi Party; and finally to a sinister clinic hidden deep in the Bavarian Forest.
