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.

X is the New York Times number 1 bestseller and thrilling, twenty-fourth book in the Kinsey Millhone Alphabet series from Sue Grafton. In hindsight, I marvel at how clueless I was . . . What I ask myself even now is whether I should have picked up the truth any faster than I did, which is to say not fast enough . . . When a glamorous red head wishes to locate the son she put up for adoption thirty-two years ago, it seems like an easy two hundred bucks for private investigator Kinsey Millhone. But when a cop tells her she was paid with marked bills, and Kinsey's client is nowhere to be found, it becomes apparent this mystery woman has something to hide. Riled, Kinsey won't stop until she's found out who fooled her and why. Meanwhile, the widow of the recently murdered P. I. – and Kinsey's old friend – Pete Wolinsky, needs help with her IRS audit. This seemingly innocuous task takes a treacherous turn when Kinsey finds a coded list amongst her friend's files. It soon leads her to an unhinged man with a catalogue of ruined lives left in his wake. And despite the devastation, there isn't a single conviction to his name. It seems this sociopath knows exactly how to cause chaos without leaving a trace. As Kinsey delves deeper into the investigation she quickly becomes the next target of this tormentor. But can Kinsey prove her case against him before she becomes the next victim?

Secret Codes unveils the hidden history and science of cryptography, exploring how codes and ciphers have shaped communication through the ages. From protecting military intelligence to safeguarding digital privacy, this book examines the evolution of secret communication. It reveals how cryptography isn't just a technical field, but a reflection of human ingenuity and the constant need for security. Did you know the Caesar cipher, used in ancient Rome, was one of the earliest forms of substitution? Or that the Zimmerman telegram played a crucial role in World War I, demonstrating the impact of codebreaking on international relations? The book explores historical contexts, scientific principles, and practical applications, highlighting the ongoing battle between code makers and codebreakers. Beginning with fundamental concepts like substitution and transposition ciphers, the narrative progresses through key historical moments and mathematical underpinnings. Chapters delve into the development of codes from ancient times to modern cybersecurity applications, examining both symmetric and asymmetric cryptography. By combining historical analysis with accessible explanations of complex scientific concepts, Secret Codes offers a comprehensive understanding of cryptography's evolution and its impact on our world.
