Microstic #4 is in the spot where new microstics go. (The picture below is non-interactive.)
To be honest with you, I think this one is pretty hard, but fair (clue E is the hardest). And when I saw the opportunity that clue F hints at, I just had to go for it. If you get through it, you’ll see what I mean! As per usual, the initials of each answer spell out the author of the quote.
I love these, T!. This one really was hard, as you noted. Had to check several letters along the way. I've made a couple of microstics myself after discovering Alex B's tutorial on YouTube. I tried using his template for a snake charmer puzzle and kept getting error messages. E-mailed for input without success. I need to circle back and see if I can figure it out.
