In the aftermath of the surrenders of Germany and Japan in October 1945, Cletus Frade and his colleagues in the OSS are given the life-threatening task of maintaining security during a covert U.S. deal with Germany for intelligence about the identities of Soviet spies in the American atomic bomb program.

August 6, 1943: In his brief career in the Office of Strategic Services, twenty-four-year-old Cletus Frade has already been involved in a lot of unusual situations, but nothing like the one he's in now, standing with a German lieutenant colonel named Wilhelm Frogger in a Mississippi prisoner-of-war detention facility. Frade's job? To help Frogger escape so the OSS can use Frogger's knowledge and connections to kill Adolf Hitler.
