Thanks greedy kite for your clue to 19. I have got an answer which seems to fit the clue - it is very involved - a very complex clue - I can't be sure!!!
I am also wanting 27 - is 'a nonny mouse' a clue? If so, I am none the wiser.!!
25. Just for the record, he had a bit of a bite. (6)
Any ideas please. !!
