Sorry this is late, I’m still forgetting that the IoS is no longer a prize puzzle and is now blogged on the day of publication.
I found this tricky until I got into Kairos’s mindset and stopped looking for the obvious definitions. Very nice puzzle, though I have to admit to a little cheating at the end to get the blog out quickly. Thank you Kairos.
There is an unusual Nina in the grid – see Kairos’s comment – number 6.

As with PeeDee, took a few minutes to get on the wavelength, then a pretty quick solve. Couldn’t parse the rather novel MIDDLE E. Thought LAWYER and SMITHS rather good.
Thanks to Kairos and PeeDee.
Good Sunday fun. Some really nice crafty definitions. ‘Kind’ for MOTHERLY being my pick of a good bunch
One thing though – wasn’t it THE Smiths?
All fairly plain sailing apart from a couple of niggles. I wasn’t all that convinced by MIDDLE E – does anyone actually refer to the E above middle C in that way? And ESTATE occurred both in a clue and an answer. But they’re only minor niggles and didn’t spoil it.
Thanks, Kairos and PeeDee.
Quite liked MIDDLE E. No, I wouldn’t refer to it that way myself, but on reflection “E above middle C” sounds a bit clumsy, doesn’t it, so why not? And the clue was the nicest in the set, I thought. All those “middle Es” didn’t need the the slightly self-deprecatory exclamation point. Pleasant solve, listening to The Archers, good Sunday stuff.
Ta to Kairos & PeeDee.
Mostly went in pretty quickly, but held up in the NE corner. I enjoyed HELLO, SMOKED, ENGROSS and EMBOSSED in particular.
A good pre-Sunday dinner puzzle.
Thanks to Kairos and PeeDee
Thanks to all for the kind comments and to PeeDee for the expert analysis.
This crossword was set whilst I was changing jobs so various of the entries in the grid can be assembled to say “Farewell Eversheds, hello Shoosmiths – Real Estate Support Lawyer”
That’s not a Nina I was ever going to spot! Congratulations Kairos on getting your new job.
