Slingshot: Spycatcher (Book 3)

In Slingshot, Cochrane is ordered to recover a mysterious document stolen by a Russian Foreign Intelligence Service (SRV) traitor working for a former high-ranking East German Stasi officer. The officer, years before, had instigated a secret pact between Russian and U.S. generals. The agreement stipulated that should it be broken, an assassin would immediately be set loose after an unknown target. The SRV has sent their own version of Cochrane, a cold-blooded, brilliant operative, to retrieve the document, pitting spycatcher against spycatcher.
