The Most Dangerous Game ...

NEWSWEEK: The Zodiac case still inspires a cottage industry, with books, films, Web sites, T shirts and a whole subculture of amateur detectives. Why is this still going on 40 years after the murders?
Robert Graysmith: I don’t think it’s good writing, a dashing detective or whatever. It’s the bizarre costume and the cryptograms. It has been called the most cerebral murder case of all time. You have to take the human anguish, the human loss out of the equation to solve this, you could not deal with it. You have to look at the ciphers and the odd costume. You realize there are still cryptograms that haven’t been broken, such as “My name is …” or a map, “This is where to find me.” Anybody with any sort of curiosity wants to know the entire story. The only thing we had comparable to this back in 1969 was Jack the Ripper, and there are about a hundred books [about that case,] and they all have a different ending.
