In nineteen sixty-nine, a killer who called himself the Zodiac mailed the newspapers a cipher and promised it contained his name. A schoolteacher and his wife solved it in eight days. Fifty-one years later, a second cipher that had defeated the FBI, the Navy, and the National Security Agency was finally read by three amateur codebreakers in three countries. Neither message named anyone.
