One of Europe's most accomplished assassins has been set loose after an unknown target and only CIA/MI6 intelligence officer Will Cochrane can stop him in this action-packed, follow-up to Sentinel, written by a real life former field officer

When a CIA double agent, working for the Russian Foreign Intelligence Service (SVR), advises his American handlers that an important document has been stolen, no one seems to know the paper's contents. The only thing they do know is this: it can kill.

In order to hunt it down, they unleash their deadliest field officer-special agent Will Cochrane. He searches throughout the European underworld and discovers that the document was stolen by an SVR traitor. At first, Will believes the Russian traitor has his own agenda but soon realizes that he is working for someone infinitely more powerful: a shadowy, former high-ranking East German Stasi officer who instigated a super-secret pact between Russian and US generals twenty years ago. An agreement, which if broken for any reason, was designed to unleash an assassin. . . .

Meanwhile, the SVR has tasked its own "spycatcher"-a lone operator who is just as ruthless and relentless as Will-to retrieve the document. Now, Will must face two, deadly clever adversaries, who will stop at nothing to achieve their aims.
