I agree with you jogamel. Orson aced it.
I have only solved a handful.
I am not sure yet how to enter the down answer.
I am assuming it could be anagrams or switching the two halves or cycling the word.
But Deisce screws up my down answers. I do not have I in 8D and I do not have a C in my 9D.
My answer to 23d is 9 letters long but the grid has only 8 cells.
Must find the extra letters, I guess.
