So Sanborn says it’s not what the misspellings are but where they are? Assuming my previous mention of duress ciphers is important, let’s take a look at the misspellings…
“One of these things is not like the other ones!”
Ok, so fancy new-fangled math aside and complicated proofs shelved. Where and what are they?
Ok, geez, chill out! There’s one in K1 towards the end, there’s one in K2 about 1/4 of the way in and there’s one word with two at the beginning of K3. Location schmocation. Or is that true? We’ve got one in each section, located in the end – middle – beginning of each section. So what? Well, each part has one word that is misspelled. There are not a bunch of misspelled words to throw off decryption, it’s a specific signifier about the nature of each “transmitted” message. So, K3 is different because DESPARATLY does not = DESPERATELY with one misspelling, there are two: A for E and an E left off. Where’s the missing Mr. E? Ask cowpattybill for I know not. You could also argue that K1 is off because in K2 and K3, the misspelling is towards the end of the word and not at the beginning. This is a valid point but my gut says K3 is still a better candidate.
So location in the plaintext doesn’t seem consistent but gauging from 2 out of 3, it is supposed to be one letter only. I guess we’ll know which one is a lie once we have the K4 plaintext.
My prediction is that K4 has a one letter misspelling.
p.s. I left out the Morse code because while it has misspellings, I think they serve a different purpose or are a result of an intentional manipulation of text such as anagramming or transposition.
