6A "Sailor - another in sea is absorbed" (7). I have an answer "BEMUSED", but not sure on parsing.
7D "Sand's dubious novel covers" (7). I have "EM?O??E" . Hints please
19A Unclued (7). Should the 5th letter of 8D Unclued (6) be spelled "A" or "O" (both spellings are in Collins)? For 19A I then have a solution (beginning with "F" and using "A" in the intercept with 8D) which Collins only gives as a type of flounder or as a synonym for a shoe without heels. It looks plausible that it may have an additional meaning fitting with 17 Across and the other unclued? Can someone point me to a reference to confirm?
