I always enjoy Klingsor’s crosswords. They provide quite a 26a but all is fair and amusing and one can always explain the clues afterwards: indeed, judging by the number of answers written down for me to look at and work out the parsing, the answers are often ahead of their explanation.
There may well be a Nina here but, surprise surprise, it’s quite lost on me. There looked as if there might possibly be a pangram, but some letters are missing. With these rather demanding crosswords I’m always so relieved to complete them that the final flourish is beyond me.
