I found this more tricky than last week but still fun, nonetheless.
There are still two clues I haven't yet parsed, namely 13d and 22d but I am sure of my answers so will plug away.
COD: Quite a few contenders, with 5d reminding me of Fawlty Towers and the cleverly constructed 9a, but I'm going with 7d purely because I can imagine a sign quoting the answer greeting anyone who comes to investigate why "dam construction is incomplete":-)
Thanks to Everyman for a fun and challenging and enjoyable puzzle.
Let us know in the comments how you got on.
Stay safe:-)
