29 across: Wally needs new stock with low-cost capital (4) NER_
I can't decide if it's nerd or nerk
Any help, and explanation of the wordplay would be appreciated!
I really enjoyed this crossword.
For 31a I had written in my letters wrong! I have it now - can't say I've heard of "lame bird" though (lame duck yes but not lame bird?) Perhaps I'm on the wrong track here!?
