Was stuck on the very same clue, in fact was about to post the last 3 that could not work out from the very same crossword.
24across, 3rd letter of 21down as in intersects:- He can\'t resist shoot(6) ??c?e?
If is it missal then that could be Secret?
Yet if this is the case then M will be the 3rd letter of 20 across
20across) Artist returns with perfect sculptor\'s framework(8) A???s?r?
Hope you can help then have a completed crossword, cheers v much, Simon
