Deciphering is an art as Enola Holmes says in the movie,but it takes passion to do one. In the 1960s and 1970s, the Zodiac Killer terrorized Northern California. He left several clues in his wake, including a handful of coded messages. But for years, authorities and amateur sleuths have failed to crack the last of his unsolved ciphers until Fayçal Ziraoui an engineer and business consultant who lives outside of Paris, claims to have finally decoded the Zodiac Killer’s final two unsolved ciphers, called Z13 and Z32 for the number of coded characters each contains. One, he says, even reveals the killer’s name: Lawrence Kaye, a suspect in the original case.That cipher, which was mailed to The San Francisco Chronicle with a victim’s bloodstained shirt, mocked authorities. “I hope you are having lots of fun trying to catch me,” the Zodiac Killer wrote.
