The easy part, is the insatiable desire to search for patterns, whereas the hard part is being able to stand back from your theory and view it with impartiality, something that is essentially impossible to attain.
We are the 'Most Pattern Seeking Animal of All', but up to now the big picture has eluded us and seems as distant now, as the day the Zodiac Killer crafted his masterpiece of evil, some 45 years ago. That is, unless you are one of the few that has declared 'The 340 Cipher solved'.

Nevertheless, questions remain on whether the 340 Cipher is indeed a complete cipher, or has any links to any of the other Zodiac correspondence he sent us subsequent to November 8th 1969. There was the Jos Kirps theory, pointing out the Paradice and Slaves connection from the Halloween Card to the 340 Cipher. We took this one stage further, to place By Knife, By Gun, By Fire and By Rope in the four Zodiac quadrants of the 340 Cipher here. Albeit, several of the letters fall on the intersecting lines. Did the Zodiac Killer intend the 340 Cipher to be dissected into four quadrants? He did place at the heart of the cipher an addition or cross point, where the intersecting lines of the crosshair would have to pass through, as well as two dashes on the extreme edges of the tenth row, on each side, that may depict the outer edges of the crosshairs. The foot of the crosshairs, runs over the Zodiac symbol on the 20th line, in the 10th column. Are these deliberate actions on behalf of our killer, or a simple case seeing of things that were never intended.
