However, the discovery may be far greater than first considered, with the 1952 Tim Holt comic the source behind the design of the 340 cipher on November 8th 1969. The Halloween card was just the confirmation that the 340 was not a cipher at all, hence the crossed "sorry no cipher" addition on the inside of the envelope, linking the Paradice and Slaves configuration back to the November 8th 1969 offering. See 'Zodiac admitted 340 not a real cipher' [pt1].' The Zodiac Killer may have been pushing us in the right direction on October 27th 1970, but his attempt at revealing the workings of the 340 cipher may have begun as early as December 16th 1969 - when just 38 days after his 'so called' masterpiece, the Zodiac Killer was claiming a potential 38 more victims.
The December 16th 1969 Fairfield letter has been considered dubious Zodiac correspondence, however, it may have been Zodiac's first foray into revealing the mechanics of the 340 cipher, albeit using a rudimentary code as a tool. There are two key features of this correspondence which possibly links it to the Halloween card - and more importantly - to the Tim Holt comic. The second we will deal with later, but the first is the rather amateurish offering of a code consisting of only nine characters.
Clearly, the Zodiac must have known that offering just five different symbols in a code of nine is open to many different interpretations and therefore practically unsolvable. Therefore, one could suggest this wasn't his intention - he was simply teasing us with the mechanics of how the 340 cipher was designed by using a rudimentary diagram based on the Tim Holt comic - and something he would expand upon nearly a year later. One can see how he uses the four Zodiac crosshairs around the large crossed circle in the Fairfield letter codethereby implying a uniformity of message in these four quadrants, but aligns five symbols as an introduction to this design. This marries perfectly with Death By Gun, Death By Knife, Death By Fire and Death By Rope. Death is the introduction, followed by the methods of death around the large crossed circle. This is exactly what he offered us on October 27th 1970, when he placed the methods of death in the four quadrants of the bisecting Paradice and Slaves. Here is a representation.
The strange symbol (with the four dots) could be a joined Z, V and F - and being preceded by four eyes - could simply be interpreted as "look for Zodiac victim fourteen", or with respect to 4-TEEN, "look for number four-teen". Up to this point and beyond, none of Zodiac's confirmed or insinuated victims (Kathleen Johns, Cheri Jo Bates and Richard Radetich) lay undiscovered, so it is entirely possible that this card was referring to the disappearance of Donna Ann Lass 51 days earlier. The skeletons indicative of a body lain undiscovered for a measurable period of time. The coloring of the four skeleton eyes may be suggestive of blood or death - a formula used in the creation of the 13 Hole postcard on October 5th 1970, where the author added a pasted red crucifix to the card.
The Halloween card could be telling us to "look for Zodiac victim fourteen" or equally "look for blood," as did the Fairfield letter on December 16th 1969 when the author stated "I will kill more people than you cops can count, so look for more blood. You better print". This discovery by Tahoe27 on December 30th 2013 was certainly a great find, but it may just turn out to be the greatest find of them all. A discovery that may finally reveal the 340 offering to be masquerading as a fully fledged cipher, that has had us chasing our tails for nearly half a century. Albeit, undecipherable at the time, the answer was probably staring us in the face just 38 days after the November 8th 1969 communication - in a letter many thought was penned by a hoaxer.
