Hi Brendan
Thanks for your help yesterday.
I'd already got 24ac. I'm struggling with 24d, which is special. At the risk of a spoiler, I have C?AO, which only leaves one word and I can't see the theme letters let alone a definition. Are my crossers right?
I think I have 21 ac. I had this earlier, but dismissed it as the chemical is not one I'd heard of. ChrisE might know.
Your hint on 43ac was really helpful.
Unfortunately, I can't get either 5d or6d. I have ?O?T?T for 5d and ?O?D?I. Are any of those letters right?
I've still to annotate my map.
