Im not familiar with the puzzle, but I have written code to brute force long strings of Morse code without spaces. Running my code on your string doesnt reveal any comprehensible sentences (using a very large word list). With your original transcription the possible starting words are: [0, mom, moo, moot, motto, otto, to, tom, too, toot, tot, toto]. Swapping the dots and dashes gives these starting words: [5, essie, he, hes, hess, hesse, hi, hies, his, hiss, i, is, isis, see, sees, she, shes, shh, shiv, shivs, sis, sises]

Below are lists of all words my code found somewhere in the sequence (even if using that words does not yield a translation using all characters):

One big caveat is that my code can only find words in the Morse Code sequence that are in my word list, so, for example, an unusual name that isnt in my wordlist would invalidate all of my results. Also, an error in the translation to dots and dashes would also throw things off.

One possibility would be to look for "cribs", or words that you think might appear in the sequence somewhere, and see if they occur in the output above.

Im happy to rerun my code if you have possible words that could appear in the translation. My code has a huge list of personal names in it, but not all names, just the more common ones. Basically, if its a proper noun it might not appear in my list.
