Watch Craig Bauer discuss the Zodiac Killer's cipher on HISTORY's miniseries The Hunt for the Zodiac Killer In 1953, a man was found dead from cyanide poisoning near the Philadelphia airport with a picture of a Nazi aircraft in his wallet. Taped to his abdomen was an enciphered message. In 1912, a book dealer named Wilfrid Voynich came into possession of an illuminated cipher manuscript once belonging to Emperor Rudolf II, who was obsessed with alchemy and the occult. Wartime codebreakers tried--and failed--to unlock the book's secrets, and it remains an enigma to this day. In this lively and entertaining book, Craig Bauer examines these and other vexing ciphers yet to be cracked. Some may reveal the identity of a spy or serial killer, provide the location of buried treasure, or expose a secret society--while others may be elaborate hoaxes. Unsolved! begins by explaining the basics of cryptology, and then explores the history behind an array of unsolved ciphers. It looks at ancient ciphers, ciphers created by artists and composers, ciphers left by killers and victims, Cold War ciphers, and many others. Some are infamous, like the ciphers in the Zodiac letters, while others were created purely as intellectual challenges by figures such as Nobel Prize-winning physicist Richard P. Feynman. Bauer lays out the evidence surrounding each cipher, describes the efforts of geniuses and eccentrics--in some cases both--to decipher it, and invites readers to try their hand at puzzles that have stymied so many others. Unsolved! takes readers from the ancient world to the digital age, providing an amazing tour of many of history's greatest unsolved ciphers.

A page-turning middle-grade adaptation of the New York Times bestseller about how a newly independent nation was challenged by foreign powers and what happened when America's third president decided to stand up to intimidation. When Thomas Jefferson became president in 1801, America was deeply in debt and needed its economy to grow quickly, but its merchant ships were under attack. Pirates from North Africa routinely captured American sailors and held them as captives demanding ransom and tribute far beyond what the new country could afford. Jefferson found it impossible to negotiate a truce, and decided to move beyond diplomacy. He sent the U.S. Navy and Marines to blockade Tripoli--launching the Barbary Wars and beginning America's journey toward future superpower status. This vivid and accessible young readers adaptation of the New York Times bestseller features an exclusive new introduction, extensive back matter, and eye-catching art throughout. Chronicling a crucial moment in American history, this historical thriller will excite and inspire the next generation of patriots.
