Moscow is no longer the gray, grim city of Soviet times. Now it is awash with oil wealth and choked with bulletproof Bentleys. But in the new Russia, power once again resides behind the walls of the Kremlin. Critics of the ruling class are ruthlessly silenced. And a new generation of Stalinists plots to reclaim an empire--and challenge the United States.

One of those men is Ivan Kharkov, ex-KGB, who built a financial empire on the rubble of the Soviet Union. Part of his profit comes from arms dealing. And he is about to deliver Russia's most sophisticated weapons to the United States' most dangerous enemy, unless Israeli foreign intelligence agent Gabriel Allon can stop him. Slipping across borders from Vatican City to St. Petersburg, Jerusalem to Washington, DC, Allon is playing for time--and playing by Moscow rules.
