内容简介：
In response to the fear that the Nazis were developing an atomic bomb, the US government through the OSS (forerunner of the CIA) commissioned a super-secret mission to evaluate the status of German science and to assess their progress in the area of nuclear fission. So what were the Germans really up to? The German scientists were all great minds capable of reaching the same conclusions as the American team. Were they morally against the bomb's development or did they just not understand the technical problems and concluded its development was not feasible? We may never know, because they publicly denied the possibility that such a bomb could be built, even after learning about Hiroshima and Nagasaki. US Army Captain Robert Brock makes a personal promise to President Franklin Delano Roosevelt to destroy all evidence that the Germans have actually perfected the design for an atomic bomb. The "favor" takes him to Greece, Italy, France, and into Germany itself, as ALSOS races to prevent the Third Reich from using their weapon of mass destruction. Go along for a fast-paced ride as Brock delivers whatever it takes to make good on his promise, offered as a favor to FDR.
