the trouble is the editor has made several mistakes and I am trying to guess the missing bits.
The answer Petty is really helpful so now I need a 4 letter word and have no clue which is why I wanted to have an opinion on 20D. If repugnant is the right answer the only info I have is -g-e.
The competition is for £25 per answer or £1,000 for all correct so its worth a guess
