The Skorpion Directive — David Stone

In Vienna for a top-secret meeting with ex-Mossad agent Issadore Galan, Micah Dalton senses that something is very wrong on the streets of the Ring District. Dalton's aggressive response to enemy surveillance makes him the target of a complex plot with the potential to shatter America's strategic alliances with the rest of the civilized world. Planned by an unknown foreign power and executed by a scarred Serbian killer known only as Smoke, the conspiracy pits Dalton against an ultrasecret U.S. agency and a cadre of trained KGB killers. In a blistering trajectory of events that takes him from Venice to the Balkans and the barren shoreline of North Africa, Dalton pushes himself to the edge of sanity in a desperate attempt to save his honor-and his life.
