Oh dear...just when I thought it was safe to go back into the water.
I rattled (by my standards) through the cold solve. Thanks Mr E for not making them too difficult. I would however be grateful for some help on parsing 2 down and 29 down.
I was about to start trying to draw some straight lines - not an easy thing to do with flippers - in the expectation that they would produce a three letter word.
I then turned to the thread and post 24 from hotelwhiskey suggests that I am on the wrong lines. Is it the first three letter of these clues or answers and why these three? Any help appreciated with thanks.
