A mathematical tour of some of the greatest unsolved ciphers of all
time In 1953, a man was found dead from cyanide poisoning near the
Philadelphia airport with a picture of a Nazi aircraft in his
wallet and an enciphered message taped to his abdomen. 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. He lays out the evidence
surrounding each cipher, describes the efforts to decipher it, and
invites readers to try their hand at puzzles that have stymied so
many others.
