Defectors by Joseph Kanon (Simon & Schuster)

Joseph Kanon's previous thriller Leaving Berlin was a best-seller and this new riveting page turner is set in Moscow 1961, with all the elements of intrigue attached to the former Soviet Union.

With the launch of Sputnik, the USSR's international prestige is at an all-time high. Former CIA agent Frank Weeks is an infamous defector and about to publish his memoirs. His revelation will more than rock the boat in the West. His defection in the early 1950s shook Washington to its core - forcing the resignation of his brother, Simon, from the State Department. 

Now a New York publisher,  he previews the memoir. But he knows the American government will never approve the publication of what is obviously KGB propaganda. 

Yet the offer is hard to turn down: finally giving him the chance to find out why his brother chose to betray his country. But the revelations contained about Moscow are far more shocking than he envisioned
