1. Establishing trade etc across ‘closed’ border? It took Pils abroad, maybe OSTPOLITIK (anag.) The first part of the clue reads like wordplay, and the redundant ‘maybe’ at the end makes the second part read like a definition. But ‘abroad’ is the anagram indicator. It’s not clear if the practice of Ostpolitik really opened up the export market for the breweries of Plzen.
12. Like sweet wine? I’ll open can AMABILE (I in am able) The punning opportunity of ‘can’ is readily grasped.
14. Refuse, old litter, card disposed of BRAN (bran(card)) Solvers need to look one entry down from the solution in Chambers for an explanation. A brancard is a horse-drawn litter.
19. Deserter, first quitting trench shelter for Belgium BUG-OUT (B for d in dugout) Azed gets the wordplay spot on to indicate the letter substitution.
25. Debauchees finding love in Parisian streets ROUÉS (0 in rues) You can bet this idea has been used a few times before, but it’s too convenient to pass up.
31. Wherein you’d find Columbus giving cries of sorrow and joy? OHIO (oh! io!) You either spot the state capital straight away or kick yourself after protracted head-scratching. Dr Watson is in the latter category.
32. Without bandages i.e. yielding pus? SANIES (i.e. in sans) The omission of a comma before ‘i.e.’ is a subtle hint to the clever wordplay.
35. ‘Man’s dirt’ is broadcast – by one such? MISANDRIST (anag. & lit.) A straight anag. & lit. is a rare find amongst the more common comp. anags., and worth celebrating.
1. Red stone arid waste in southern States SARDIUS (anag. in S US) ‘Waste’ looks suspiciously like the nounal anagram indicator that Azed is normally averse to.
5. They may result when a shot’s miscued OATHS (anag. & lit.) Slightly more straightforward to spot than 35 across’s anagram, but this calls for a double celebration!
18. There’s money in skin lotion – it’s better for me the longer I live TONTINER (tin in toner) A tontine scheme rewards the last surviving member so disproportionately that it provides a strong incentive to ensure the other tontiners die first, and so makes a great plot device for a murder story.
21. Basketball team on the up look for yet more YANKEES (seek nay, all rev.) Solvers scrabbling around the internet’s sports pages in search of a Yankees basketball team can probably reassure themselves that Azed has mixed up the Yankees with the Knicks and should have specified ‘baseball team’. Hopefully all we be explained in the next Slip.
29. Concluding bits of airport trash you purchased – it’s often dull THUD (last letters) An inspired definition, that perhaps deserved a slightly more interesting phrase to provide the last letters.
30. ‘Our gods wrong one’ – how Cicero finished speech? DIXI (di X I) “I have spoken”. An appropriate solution to close the puzzle. ‘Di’ is the latin plural of ‘deus’ and this makes a welcome change from the usual setter’s choice of ‘girl’.
Across: 11. VARA (vara(n)); 13. CRYPTO (cry PTO); 15. HELMETED (mete in held); 16. MIMOSAE (I’m in mo + SAE); 17. ÉTAPE (hidden); 24. BENGAL (BEng al(l)); 26. SISTINE (anag.); 28. STRAICHT (anag. in tarts, rev.); 33. MUSTELA (anag.); 34. EXEC (X in EEC).
Down: 3. TRYP (hidden); 4. PAPPOOSE (poos in pape(r)); 6. IMPLEX (imp lex); 7. TAGMEME (tag me me); 8. KIRTAN (ta in kirn); 9. SLAE (s + anag.); 10. GENDERLESS (anag. less I)); 13. CUMBERSOME; 20. UPSIDES (up side’s); 23. OSCULA (scul in o/a); 27. STAID (‘stayed’).
