I have just finished the puzzle and decided to review the comments.
Several posters referred to a missing word on 8d which reads
They go from bank to bank to stay in business.
The answer is ferrymen.
Ferrymen go from bank to bank in a river or other waterway to earn their living. If they do not go from bank to bank they will not earn any money, so they will not stay in business.
So can somebody tell me what is the missing word, and why.
Thank you
