Best-selling author Brad Meltzer and the team jump at the chance to take on one of the FBI's most puzzling unsolved crimes: the 1971 disappearance of airline skyjacker D.B. Cooper, who bailed out of a jetliner at ten thousand feet over Washington state with two parachutes and two hundred thousand dollars in ransom money strapped to his body. Working closely with the former FBI agent who headed up the unsuccessful search for Cooper, Brad and the team examine new evidence that points to a former airline employee named Kenny Christiansen, whose own brother suspects he was actually the skyjacker who called himself D.B. Cooper. This sets up a climactic meeting between the Decoded team and Christensen's possible accomplice, the man who may have helped D.B. Cooper and his two hundred thousand dollar ransom vanish into thin air.

Every now and then a researcher will discover a historical enigma, an unproven rumor, a story with a puzzling outcome. Such encounters are an irresistible challenge for Brad Meltzer, the #1 New York Times best-selling author. What if I told you Fort Knox was empty? Buddy, Scott and McKinley travel to Kentucky to investigate the history of the legendary vault, and discover the devastating impact it would have on our economy and our pocketbooks if the gold were gone. Fort Knox has not been audited since 1974, but does that mean the government is shielding its empty pocket book from the prying eyes of the American public, or is the privacy in place to protect a different secret altogether?

Best-selling author Brad Meltzer and his team thought they knew what the Statue of Liberty stood for. But now they learn that America's most powerful icon of freedom might actually be loaded with secret symbols put there by a sinister group bent on world domination. They investigate claims that the Illuminati, a secret European society loosely affiliated with the freemasons, turned every inch of the statue into a coded message, from the torch Liberty holds high, to the rays emanating from the crown, even to the precise height of the statue itself. Things get even stranger when a highly regarded numerologist shows the team why he believes the statue is really a monument to the all-powerful number 7. As they evaluate these unsettling claims, Brad and the team are forced to reconsider whether one of America's most enduring symbols is really who she appears to be.

What if I told you there's a place in Alaska that claims more bodies than the Bermuda Triangle? The Alaska Triangle--the region between Anchorage, Juneau and Barrows--has a disappearance rate sixteen times the national average, and scientists are entirely incapable of explaining why. Is it Alaska's extreme geological activity that creates magnetic anomalies causing instruments--and humans--to act crazy? Or is it vortexes--swirling, turbulent flows of energy--that are causing entire ships, planes and people to disappear without a trace? Local tribesmen, Search and Rescue workers, and the families of the missing all have their theories as to what is causing people in Alaska to vanish off the face of the earth.

Best-selling author Brad Meltzer and his Decoded team examine claims that John Wilkes Booth actually escaped to freedom after murdering President Abraham Lincoln in 1865. The "official" version of events says federal agents cornered Booth and killed him just days after the assassination. But Brad and the team uncover glaring inconsistencies in that 150-year-old account: Why did the authorities hide Booth's body from public view? Why was Booth autopsy's conducted in complete secrecy in the cramped confines of an ironclad gunboat? Searching for answers to these and other troubling questions, the team finds startling evidence that strongly suggests Booth may indeed have lived into old age without ever facing punishment for his crime.
