Thanks to Zamorca and Grant. A quick but enjoyable solve. I needed all the crossers to get EVILDOER and wondered about the absent-absence repetition.
I agree a neat puzzle. My only gripe is that taxi driver is a bit too obvious when the clue starts with cabbie
A quick solve — many of the surfaces themselves led to the answers without me needing to fully parse the clues. Nonetheless, there was a lot to like in this crossword. Thanks Zamorca, and Grant for filling in the parsing details I didn’t catch like TAXI in TAXIDRIVER and the double definition for STURGEON.
Thanks Zamorca and Grant
Straightforward puzzle that was mostly done over a lunch time with a couple to be polished off afterwards. No real holdups and finished with the two long ‘ABSENCE’ clues at 13a and 11d.
