Working honestly or dishonestly? (2,3,3)
I believe the answer is:
on the sly
'dishonestly?' is the definition.
'working honestly' is the wordplay.
'working' indicates an anagram.
'honestly' is an anagram of 'ON THE SLY'.
'or' is the link.
(Other definitions for on the sly that I've seen before include "Behind someone's back" , "Under the table" , "Surreptitiously" , "in private" , "Done in an unpleasant and secret way" .)
