Mephisto 2609 – Tim Moorey

Across
1 SCHAPSKA = a lancer’s cap – CHAP’S in ASK*, the anag. indicated by the adjectival version of must4,
7 ADES – Miltonian version of ‘Hades’, and musician/composer Thomas Adès, who I dimly remember as a young promenader in the late 1980s – we probably played in the same game of pavement Black Maria or Scrabble outside the Albert Hall. So rather embarrassing that this was a late answer.
10 EXAC(ERBA=bear*)T,E
11 TAVE(r)NER – another composer I should have identified far quicker, especially when our musical history has both a Taverner and a Tavener, both called John
13 IMA(x),(mada)M – not sure that imams are necessarily any stricter than rabbis or parsons, so slightly puzzled by “Strict religious leader” as the def
14 FAR-OUT = amazing – that’s the easy part. I didn’t see “Far(t ab)out” for “fool around” until doing some searches of the Chambers CD-Rom to hunt for wordplay
15 CAVEL = Scots for a piece of wood used in casting lots, and hence “chance”. Last L removed from Edith Cavell
16 TO(N,DIN)O – I thought of “tondo” for the round painting but didn’t see the possibility of a round miniature until nearly the end
18 A,TWITTER
20 C.(LEAVER)S.
23 HET=angry,AIRA = rev. of aria
26 OUSEL = a Shakespearean dark-complexioned person as well as a blackbird, and “louse”=parasite with the L moved.
27 (c)LOSING – losing as in “You’ve lost me there, Peter” in response to something complex
28 TWAL = Scots for twelve – it seems that in at least some Scottish courts, juries have 15 people
30 A(POST)LE
31 DIKEL=liked*,O.U.P.,E.R.
32 SEER or seir is the Indian fish. I don’t understand the wordplay of this one
33 A,F.T.,ERE,YE – I can find aftereye as a Shakespearean verb “to gaze after”, but not a nounal look.

Down

1 S(A)TI(r) – this should have been an immediate answer, but got hung up on clink being jail or gaol, and then looking for words with too many vowels to stand much chance of existing
2 CHAM=autocrat (an obsolete form of ‘khan’, and presumably the “Great Cham” that Samuel Johnson was),AE. = aged,LEON=Spanish capital of province with same name
3 AXEMEN – “A Yemen”, with X replacing Y
4 PANS=harshly criticizes,LAV=John
5 SCEATT = the old coin – C=100 in (Tate’s)*
6 AR(G)AN – a tree with oil-bearing seeds
7 A BO(R=rule)D
8 DA(COIT = Aussie buttocks)Y
9 SECT=class,ORAL=test
12 FUN=play,E,REALLY=very
15 CIC,HLIDS = L in dish*
17 NETSUKE – U.K. in tense*
19 I.(SO=very,TOP=best)E.
21 R(A J.P.)UT
22 GUTSER = rev. of “res., tug” – time wasted looking up other possibilities like BUTSER and BUSSER
24 AIDER = “Ada”
25 INULA – rev. hidden in “naval unit”
29 LEVE = variant of lief=willingly – to “level” is to speak honestly
