In the history of the United States, there have been over two dozen assassination attempts on the President.

Four have been successful.

Historians have branded the assassins four lone wolves. But what if they were wrong?

Now there's a killer in Washington, DC who's meticulously recreating the crimes of these four men. And Beecher White has just discovered the truth: over the course of a hundred years, all four assassins were secretly working toward one goal. How are they connected? Who do they work for? And why are they planning to kill the President today?

Beecher's about to find out. And most terrifying, he's about to come face to face... with the fifth assassin.
