Scorpion is, I find, the hardest of the Indy setters and this puzzle was no exception. There were some novel approaches and some areas I am not entirely sure of all the reasoning. These are mentioned below.
Solving time (slowest of year so far, I think) 77 mins
* = anagram
ACROSS
1 SECOND Very clever – a particle of a minute.
4 PISCATOR i.e. an angler. I got the idea straightaway from “rod” and “bank” but getting the right word took a while longer.
11 H(arr)Y FORD (reversed) + OIL i.e. HYDROFOIL
12 MANGOES, I think. It’s fruit all right. My thought on the wordplay is that chestnut refers to hackneyed jokes starting “A man goes” i.e. “opening of old chestnut”.
13 f(A) c(U) + SPICE = season
22 THE SWAN (AS NEWT + Here)* “The Swan” as a typical pub name is my guess.
24 IAN BOTHAM Have still not quite adjusted to seeing living people in the crossword, but this is an excellent &lit. (IcONBAT)* i.e. caught (c) out + HAM = joint. As for the surface reading, I thought that was what the Indy set itself out, on foundation, NOT to be !
25 T (ARK) A The otter from Henry Williamson’s book, I think i.e. a fable. TA = appreciated i.e, thanks. ARK = haven
26 THE LASS (rev) Y i.e. THESSALY. You needed to know that the French for “tea” is “the” (there should be an accent on the e but this is ignored in crosswords) and the Spanish for “and” is “y”.
27 FRIEND FIN interleaved with RED. Phew!
DOWN
1 SK IR(M)ISH I’ve learnt today that the postcode for Stockport is SK
2 COLON A doubt Definition would seem to fit “Waste disposal component”. The “spotted” might refer to the dots in the sign for a colon (:) but I do not see where “manual” comes in.
5 INDIANA (polis)
6 CROSSWORD SETTER Delayed here by writing SOLVER first, but agree SETTER is more accurate – “his work”
9 PHYSIO “fizzy”
15 ABERRANCE (CANBERRA)* E “fans” indicates the anagram. Nice play on the meanings of “slip” (a fielder in cricket)
19 AUTUMN Hidden reversal – Hidden indicator a bit fuzzy, but no complaints when I found any answer in this puzzle.
20 CH (leade)R IS T(horns) crown = first letter. Impressive, that.
23 Shane WA (R) NE Best clue of all.
Tough indeed. Some very good stuff here though; like nmsindy I thought that 24A and 23D were both excellent.
