This was a complex preamble, and I think the description of the overlap was poor. But we've discussed that already, and to be fair I'm not sure how to word it better! I have punctuation marks in 3, 4, 6, one letter which completes the asterisk man, and two marks (both the same) which I artistically copied from an example I found with google's help. I took the message, figured out how to read it, and then obeyed the first three words. Then I obeyed words 4, 5, 6 and 7. Then I obeyed words 8 and 9. There were two ways to do the last bits, one gave gibberish YNOEJGO while the other gave me the start of a thematic title so I replaced the encircled letters that way as instructed, wrote the remainder of the title below, then realised what the dedicatee business was all about, googled for the 11/6 and asterisk man in the light of that, stuck it all into an envelope and went for a lie down.
mdmaylwin, 24 is not an anagram, though it took me a while to realise that -- it so very nearly is! A synonym for utter is written "to port", plus a last letter, to make the definition at the end.
Like mdmaylwin, I cannot see the anagrind in 8. Is this just a bit of loose clueing, or is there a way to parse it I haven't spotted?
