I have put the words from the text into the crossword puzzle. The puzzle reads For Truly Yours Much Thinking Too You Intense. I have tried taking the letters identified on the grid and anagramming them. I have tried taking the ten letters so identified, removed the two of them that also appear in the word Black (there is no black box in the grid) and anagramming the eight of them. I have filling the border based on the colors of the marked letters (leaving the Black one blank) and don't get any kind of sensible answer.
I am stumped. It's probably that I'm too tired to solve it.
