On a mission to hunt down the men responsible for the Pan Am Lockerbie terrorist attack, Mitch Rapp has been steadily working his way through a list of men. With each kill, the tangled network of monsters responsible for the slaughter of 270 civilians becomes increasingly clear. His next target is a plump Libyan diplomat who is currently in Paris without a single bodyguard.

Rapp finds him asleep in his bed, and unprotected. With conviction of the man's guilt, he sends a bullet into the man's skull. Suddenly everything changes. The door to the hotel room is kicked open and gunfire erupts all around Rapp. In an instant the hunter has become the hunted. Rapp is left wounded and must flee for his life.

The next morning, the news breaks in Washington that Libya's Oil Minister, three innocent civilians, and four unidentified men have been killed. As the finger pointing begins, Rapp's handlers have only one choice: deny any responsibility. Their newest secret weapon is now a liability, and hopefully gone for good. But it will soon become clear that there is nothing more dangerous than a wounded and cornered Mitch Rapp.
