End in sight.
I have been through the grid twice and can only find 8 missing letters:
1a M, 6a I, 1d A, 12a R, 8d B, 19a T, 32a C, 37a O
Any help on the other two appreciated
Thanks for this Uncle_c.
You have confirmed what I thought.
However, I can't seem to get the second "I" and second "M"?.
As always any pointers appreciated
12a - the answer is a word meaning barrow(mound), the wordplay gives you a three letter word meaning pushed that needs to be reversed around the "scene" letter
