Query: Is the defector telling the truth?

Stone heads a secret intelligence organization operated by the Joint Chiefs of Staff. Its function is to infiltrate Russia if the need to do so ever arises. So far, it hasn't. But when Stone debriefs a Russian defector who has offered information about Russia's position at upcoming arms reduction negotiations, he questions the defector's authenticity. Stone infiltrates Russia and impersonates a KGB officer to find the truth, enlisting the help of a prostitute and a Stalin look-alike.The Debriefing is tightly plotted, Littell's writing style is crisp, and although the characterization is one-dimensional, the story is fun. It isn't as good as his first book,The Defection of A. J. Lewinter, nor is it as enjoyable as my favorite (so far) of the Littell books,The Sisters, but this brief novel is one that fans of espionage fiction should enjoy.
