Top secret : a clandestine operations novel
(Book)

In the first weeks after World War II, a squeaky-clean new second lieutenant named James D. Cronley Jr. is spotted and recruited for a new enterprise that will eventually be transformed into something called the CIA. In his first assignment, he's got seven days to extract a vital piece of information from a Soviet agent, but there are enemies everywhere--and, as Cronley is about to find out, some of them even wear the same uniform he does.
