Book Description
This is not a book about the Zodiac Killer. Hundreds of books, articles, movies, television shows and much more are out there if you want to know about the Zodiac Killer. It is a tale that has been told and retold, written and rewritten, thousands of times. This is something you have never seen before, even if you follow this subject. While the book must cover the basics of the case and introduce new readers to just exactly what a "Zodiac Killer" is, what he did, and the many letters he had written, the bulk of the book is dedicated to something completely new that most have never seen. Zodiac mailed a map to he newspapers and police with one of the many letters he had written. This map was completely blank except for a compass that had drawn over a place called Mt. Diablo. Zodiac said this map could be used to find an alleged "string of bombs" he had planted beside of a road somewhere waiting for a school bus to go by. He also said this map somehow involved something called "radians". But no one knew how to use a blank map to find marked locations. For over half a century this remained a mystery, until now. A bomb schematic sent by the mad man and puzzle maker turned out to be one of the keys for this map, one of a couple. An overlay key. Using a method that has been used throughout history. Many examples can of this method can be found and this method is also taught in the military. He created a map overlay disguised as a bomb drawing. When two points on this drawing are aligned with two points on the map, one being the compass, marked locations can be revealed as well as a section of highway marked with a string of bombs. Whether these bombs were real or not is beside the point (but you would think that the world would want an answer to that question) , what the real mystery and importance of these places are is another question entirely. Zodiac was most famous for the codes he created to taunt the police and not the murders he committed. Only one of his codes was ever said to have been solved while several others remain a mystery to this very day. His most famous unsolved code is called the '340 code'' for the 340 symbols that comprise the code in a grid like formation. This book will also delve into the possibility that this code is also an overlay key for this map and it is used to find the long sought after "radians" that Zodiac said we would find. Clues and evidence from his letters go to support this very idea. That is for you to decide. Don't believe what I tell you. Believe what I show you. Believe your own eyes. This may be the key that someone uses to solve the mystery once and for all..

Category : Ciphers
Languages : en
Pages : 320
Book Description
From the earliest days of mankind, people have sought to pass on secret messages via code - and for almost as long, cryptographers have tried to break the codes. Most famous of all were those at Bletchley Park who managed to break the Nazis' 'unbreakable' Enigma code.This fascinating and intriguing book examines some of the most difficult codes in history that have withstood years of investigation and shows the reader how they too can learn to solve or create almost any code. Sometimes, as with the notorious Zodiac Killer or the Voynich Manuscript, the codes remain unsolved, or as with Kryptos in the CIA's headquarters only 90 per cent has been decoded. In the final element of the book, working with a team of top cryptographers, the author has devised his own code, based on the techniques that have been revealed throughout the book, and invites the reader to crack the code...

Unsolved!
Author: Craig P. Bauer
Publisher: Princeton University Press
ISBN: 0691192294
Category : Computers
Languages : en
Pages : 636
Book Description
"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"--

American Ripper
Author: Patrick Kendrick

ISBN: 9781604521634
Category :
Languages : en
Pages : 594
Book Description
American Ripper is the true story of Gerard John Schaefer, a Florida Law Enforcement Officer who was a prolific serial killer in the late 1960's early 1970's. The decade that was thought to be filled with "Love, Peace and Happiness," became a new dark age, breeding more serial killers than any other time in U.S. history, including Charles Manson, the Zodiac Killer, the Son of Sam, John Wayne Gacy and Ted Bundy, who was held in the same prison as Schaefer and whom he both idolized and resented for the recognition his crimes brought him; a recognition Schaefer never received. This book chronicles Schaefer's life, education, his career as a cop, and his path to become a sadistic murderer. Based on empirical, extensive research that includes reviews of the case's investigation and subsequent trial, interviews with families of victims, numerous police and attorneys involved with the case, forensic doctors, and the killer himself, the author attempts to discern how Schaefer became the antithesis of what a lawman should be. Schaefer's metamorphosis can never be rationally explained, but reviews of the case's transcripts, the killer's psychiatric evaluations, and the author's own experience with Schaefer help paint a picture of an unfettered mind that fed on its own darkness. The case also reveals an incredible and inborn weakness of then-law enforcement, a lack of shared information, and an inherent and global disbelief that monsters, such as serial killers were so abundant. Much has changed since the so-called "hippie generation," but a time that should have been filled with hope became an era that was infested with enigmas such as Gerard Schaefer. Patrick Kendrick is the best-selling author of Extended Family and the award-winning Papa's Problem.
