#1 New York Times bestselling author Brad Meltzer returns with a pulse-pounding new novel of lies and deception at the highest levels of government. There are stories no one knows. Hidden stories. I love those stories. And since I work in the National Archives, I find those stories for a living. So says Benjamin January, a young archivist who spends his days working with the most important documents of the U.S. government. When Clementine Kaye, his first childhood crush, shows up at the Archives asking for his help tracking down her long-lost father, Benjy tries to impress her by showing her the secret vault where the President of the United States privately reviews classified documents. It is also where Benjy and Clementine accidentally happen upon a priceless artifact-a 200-year-old dictionary that once belonged to George Washington-hidden inside a desk chair. Eager to discover why the President is hiding this important national treasure, the two soon find themselves entangled in a web of deception, conspiracy, and murder that will reveal the most well kept secret of the U.S. Presidency.
