Refusal to admit endless crooked dealing (6)
I believe the answer is:
denial
This might be a double definition.
'refusal to admit' is the first definition.
(I've seen this before)
'endless crooked dealing' is the second definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for denial that I've seen before include "Act of asserting that something alleged is not true" , "Negation" , "Daniel (anag.)" , "Saying it isn't so" , "Rejection or refusal" .)
