Many thanks to Jack, a relatively recent Guardian setter. I've been a big fan (herpetophile?) of Serpent, his
nom de plume in the Indy, and Jack is proving equally enjoyable.
Great fun this week with many "outside the box" clues. Serpent is known for Ninas (often of the musical variety), and there could be some bonus constructs in the filled grid...
Started out slowly, feared DNF for a while but gradually got on the wavelength. Solving time slightly longer than Prize norm, but nonstop pleasure.
FOI 4, LOI 21.
Too many good clues for one COD. First tier of contenders 22, 2, 15 and 13. Second tier 16, 6, 19, 23, 3 and 21.
