Bobby, have you found enough letters to google the work and authors? There are quite a few full and partial anagrams where knowing the extra letters is a great help.
The 8 letter answer comes from "Prior mostly...", extra letter R, involving a 5 letter word for contempt.
Anagram of canon - n within a word for black.
Cheers Tomsdad, got the translator about an hour ago and now have a full grid, apart from the four letter entry in the penultimate row where I have ?ote. I must have made a booby somewhere since I seem to have five extra words and nothing that fits said ?ote !!!
