Gitto, you are not alone! Fortunately the problem with the setter didn't last very long. I have a third regular failing - compound anagram spotting. Not an issue today though.
I thought it was quite pleasant to have a relatively straightforward puzzle - the teeth-grindingly difficult ones are a great challenge but just once in a while it's nice to start and finish on the same day.
I twigged the likely source of the perimeter and was then crestfallen when it wasn't in the poem I thought it was (about Joan Hunter Dunne, which, if read in an 'I'm Sorry I Haven't a Clue' mode, could actually be rather rude!)
