The solution of that cipher provides us with the name of San Francisco's most infamous serial killer. However, it is not presented as just another "theory" from some armchair detective, or even from the author himself, a highly respected, veteran LAPD homicide detective. Rather, the solution comes from the killer's own mouth, written in his own hand--it is Zodiac's personally signed confession!
