Info, ultimately suppressed, had exposed setter's disgrace (6)
I believe the answer is:
infamy
'disgrace' is the definition.
(I've seen this in another clue)
'info ultimately suppressed had exposed setter's' is the wordplay.
I cannot really understand how this works, but
'setter's' could be 'my' (belonging to the crossword setter) and 'my' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for infamy that I've seen before include "Bad reputation, notoriety" , "Villainous act" , "bad report" , "Ill repute" , "Wicked reputation" .)
