Great Monday puzzle from SLORMGORM.
Plenty to like in this morning’s challenge. With 3d and 18a I was almost convinced I needed to find another 18a, but alas no further evidence of a theme. My nomination for clue of the day would be 4d (also a new term for me). Many thanks to Slormgorm!

Like Teacow, I enjoyed this very much. I was surprised but laughed out loud at 1d, loved REDTAIL and REDHEAD in the corners and was wondering about a possible ‘duke’ theme since it appeared twice in the cluing, along with my favourite answer at 14d.
All neatly clued and eminently gettable for the perfect Monday solve.
Thanks Slormgorm and Teacow.
I remember the late Bunthorne saying that as a lad he noticed that GARTONS (whatever brand that was) spelt backwards was SNOTRAG-nice to be reminded.
REDHEAD for some reason defeated me-lets just say I was exhausted after Paul.
Thanks Slormgorm, that was excellent. TYSON was my clue of the day — an &lit and an apt surface describing his antics in the ring. I also enjoyed TIRED, SNOT RAG, and BORED, the latter mainly for its amusing surface. Thanks Teacow for the blog.
Thanks to Slormgorm and Teacow. Very enjoyable. I started off slowly and had some false starts – e.g., unadorned rather than UNATTIRED and was slow to get Mike TYSON my LOI.
Very good and enjoyable puzzle. A trademark Slormgorm/Hoskins SNOT RAG at 1d, with my naturally outraged reaction in the surface for REDHEAD at the opposite corner of the grid. CARNIVORE and TYSON also earned ticks.
The only one I was unsure about was TAIL for ‘detective’ at 8d, even though we’ve probably had it before.
A big thanks to Teacow and Slormgorm.
Mostly good straightforward fun, with some entertaining clues. My only question was over REDTAIL, which I assumed must be a bird I didn’t know…But it isn’t, so far as I can see. There are red-tailed hawks in N America, but I can’t find anything just called a “redtail”, except an Australian damselfly, which is unlikely to be a high flyer. It went in, anyway, of course, so it was only when I tried to learn this new word after I had finished that the doubt crept in.
Many thanks to Teacow for the usual great blog and to all who solved and commented.
For Perplexus, the REDTAIL is the red-tailed hawk according to Collins (main FT dictionary), Wordweb and the SOED (though the latter has it hyphenated). It is also a term for the redstart according to WordWeb and SOED, but Collins doesn’t mention that.
Cheers to everyone and see y’all next time around. π
Very enjoyable even though I failed dismally in the SE corner.
My thanks to Slormgorm and Teacow.
Clearly being thick, but canβt quite see how the βI amβ in 28A relates to REDHEAD. Help!
Enjoyable enough, though we had to puzzle a while over a few, with some penny-drop moments when we got them, notably AORTA, PEANUTS and ELLINGTON. We took REDTAIL on trust as it’s not in Chambers and we couldn’t be bothered to find our copy of Collins.
Lemski@8: We think the whole clue is how a red-headed person might cryptically describe their hair.
Thanks, Slormgorm and Teacow.
FWIW, I have three dictionary apps on my phone, and all three define redtail as either the red-tailed hawk or the redstart. Perhaps Chambers is odd man out on this word.
Thanks Slormgorm and Teacow
Actually did this one on Monday but only got to check it off tonight. As others have said, a really enjoyable puzzle to start off the week. Did it across three shortish sessions grabbed in gaps in another busy work from home day. Enjoyed the clever cryptic and double definitions with the clue for TYSON drawing a wry grin. Liked REDHEAD too when the penny dropped.
Finished in the SW corner with TEPID, PROMO and the clever CARNIVORE (loved the definition).
