On double checking my clues for making sense(of a sort) I've noticed options for 28A and wonder how others see it....
1. Girls folk - her ring missing ??? ????heron responsible
or
2. Girls folk - her ring - miss in g??? ????heron responsible
or
Something else entirely - if option 1. the unchecked letter of the three letter word has two possibilities.
Hope that made sense
