Paris Weekend A Spy Novel

He has the perfect cover: a Cuban refugee from Castro's Communist ''paradise,'' married to an unsuspecting all-American woman with whom he has the typical teenager.
But Paco, the swank travel agent for the wealthy in Manhattan's Upper East Side, had served all along under deep cover as a KGB agent during the Cold War. He now works for the new Russian Intelligence agency, the SVR. From time to time Moscow sends him on a mission outside the United States. This new task appears to be deceptively simple: retrieve a small vial from a rival agent in Paris. A short trip, no longer than a weekend, quickly turns into a nightmare as a forgotten past intersects with the mission at hand.
Will Paco succeed in retrieving the vial from the mysterious Steiner? Or will he choose a different path and kill the mysterious terrorist known as 'Meteque'?
