Unsavory (5)
I believe the answer is:
seamy
'unsavory' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for seamy that I've seen before include "Sordid, disreputable" , "Disreputable (side)" , "Sleazy, sordid" , "Squalid" , "Marked with joins; disreputable" .)
