Thanks to Tramp for an enjoyable Prize.
Thankfully, I didn't have any issue with 18d as that word for "mansion" crops up quite frequently in barred puzzles. Actually, now I think of it, I'm sure I've seen it in previous Prize crosswords as well - maybe Jono can shed some light on this.
5a - I do have a slight issue with this in that, If I'm correct that the wordplay is split 1,2,4, then I'm at a loss to see which part of the clue gives us the 2.
I did check the 2 in Chambers thesaurus but, oddly, that word doesn't appear when you click on it, rather "by" does and, yes, one of synonyms of "by" is the 2.
My query is would the Guardian Prize really be that convoluted or am I missing a really obvious connection between "before" and 2?
COD: I had written in 24d, but the more I see 11a (which is a lot given that it's directly under the aforementioned 5a) the more I like it - so it's a tie this week.
If you're a regular reader of this blog but have yet to post anything, then why not take a leaf out of new member Nickonian's book, who posted for the first time last week, and join our merry band yourself. I promise you we're a friendly bunch and are always happy to read feedback and gives hints to answers or explain parsings when needed.
Stay safe:-)
