Have solved it all to my amazement but can't see why 23a "Short person from the continent she's screwed once more" is Afresh. I can see that esh is an anagram of she and Afr are first 3 letters of Africa and once more is afresh but where does the short person come in? Also 22d "Remove listening device from old t i t (electronic key implanted) " is debug. To debug is to remove listening device but how does rest of clue fit.? (There are no gaps in t i t but didn't know if the censor software would allow it) Thanks
