I was going to put that there is a very definite theme to this week's puzzle by Puck but, looking over it again, there are only four or five clues associated with 1a. - which I think falls short of a theme.
It's a difficult crossword to gauge in terms of difficulty because one has access to Google, which I would really have struggled without, but there are a few long anagrams and partial anagrams that give a way in, so that helped a lot.
There are some truly excellent clues with the most deviously hidden definitions, 5d for example where, after staring at possible options for ten minutes, I became convinced my crossers were wrong, only to finally see the the definition!
COD I'm giving to split between 12a (another brilliantly hidden definition) and 28a for there dual use of the "red can".
An excellent puzzle, especially if you're a fan of 1a - and who isn't?
Thanks to Puck.
Stay safe:-)
