Beyond his mastery of the craft, however, Henle was driven by a lifelong urge "to show people beauty." "I am obsessed," he said, "by showing them beauty."".

World War I did not bypass Latin America. Within days of the war's outbreak, European belligerents mobilized intelligence assets and secret diplomacy to compete for Latin America's allegiances and resources. This intelligence war entangled all of the American republics and even Japan. Dreary consular offices from the Rio Grande to the Straits of Magellan were abruptly thrust into covert activities, trafficking in fugitives, running contraband and conducting sabotage. Revolutionary and counter-revolutionary movements, big oil, international banks and businesses were also drawn in. Drawing on long-classified U.S. intelligence documents, this narrative of the Latin American intelligence war reveals the complexity and chaos behind the placid veneer of wartime Pan-America. The author connects the dots between Mexico City, Buenos Aires, Guatemala City, Lima, Havana, Santiago, Rio de Janeiro, Berlin, London, Washington, Tokyo and dozens of safe houses, front companies, consulates, legations and headquarters in between. Scores of unrecognized veterans of the intelligence war are revealed.
