Your mission, DQNian, should you choose to accept it, is to unravel the mystery of the Zodiac killer.

The best lead for you to pursue is an uncracked cipher. He has sent a total of four confirmed correspondances (one divided into three parts) in which he employed cryptography. He only used a simple substitution cipher for the first which didn't take too long to crack. We have no reason to believe he would deviate from a substitution cipher for following correspondences, given he was presumably well educated though his desire to be heard was far greater than that of lauding his intellect over others. Albeit, the other three ciphers have yet to be solved.

The one urgently demanding your attention is enclosed.
