The plot thickens! Thanks for the helpful hints but I’m now more puzzled. I had indeed counted from left to right and so confused matters by identifying 22d as the 7th normal down clue (rather than 6th). But I’ve gone awry somewhere because I’ve inserted the 2nd item in the 8th normal down clue (8th both conventionally and as per left to right numbering!). That longer word “sounded” right, if you see what I mean. I’d better look again!
