Got the idea today, but struggling with one or two clues. Please can someone offer help with 13d? More than one fell in shadows with nails splitting (9); there is a redundant letter in the clue which I think is N. I have ?I??SI??S
A fun tribute to National Limerick Day. I thought one phrase in the preamble had to be stretched a bit, but I couldn't think of alternative wording so I'm happy just to appreciate the puzzle as a whole.
