Everyman 3431 yesterday included "Information for fool with illegal drugs (4)" which must count as a triple clue. Had never seen one before and this comes along at the exact time you post your puzzle. Maybe they've been there all along and I've just been too slow to spot them.
Do you want a few hints, Rosalind? I did that bit last, too, but am pretty sure of the answers, tho' not always of the parsing.Could keep it relatively cryptic, if you like...
OK, here goes for the two longest:
25a Think of an infamous Jack & you've got 6/7 of the answer!
15d Find a synonym for the 1st word in the clue!
(Hope everyone agrees they're right then!) gk
Thank you GK, well on the way now. Had the wrong word ending for 21 ac, which perhaps accounts for my denseness.
Think 25 ac very clever now I've got it!
looks like you're there GK, well done Rosalind.
I will post the explanations later, after clue chain or maybe a bit later cus I have to write them out first
