Heigh ho, Frannie here - as if you hadn't already guessed by the tardiness and the dashed high numbers above. (I've just finished a Lord Peter Wimsey mystery in which I quite enjoyed the lingo.)
I am a little rusty at this review business after two months off, but with any luck and a little Easy Off, I'll be back out of the fire and into the frying pan before you know it.
Call me a square if you want to, but I'm not super happy when I open a puzzle and see circles. Figuring out how to parse the circled letters into THEWORLD took me a little minute at the end of the solve. That done, I'm not quite sure I get the point of the four sets, one each in a corner. If it's supposed to be four WORLDs circling the [SUN], then shouldn't it be just WORLD or aWORLD? Which brings to mind the old red wheel barrow. But, maybe it's four corners of THEWORLD? But those don't go around a sun. I'll have to ask Horace about it when next I see him. Or, perhaps one of our esteemed readers will enlighten me.
Anywhoo, I think the circles started me off on the wrong foot and I didn't have such a good feeling about the puzzle while I was doing it and after I finished it, but when I reviewed the clues and answers, I found some goods ones. To wit:
5D. Leave nothing behind? (STIFF) - this one could double as Huygens material. Maybe ADRIENNE could, too.
56A. Owing (SHY) - what, did a bunch of cheapskates put this puzzle together? :)
48D. Makes sound (HEALS).
Also, RATHOLES, SADLOTS, and BITER are all nice, in a not-so-nice way, and ETRURIA at 15A. brought back some very pleasant memories of time spent in that part of THEWORLD. Ha!
There were a few of what I'd call NYETS in the grid, such as ASASON, ULNAR, TORO, DEW, AHL, or INKER, but perhaps others would stamp them FDA. That's just the way TIS in this world.
