See art involved in puzzle (6)
I believe the answer is:
teaser
'puzzle' is the definition.
(I know that puzzle can be written as teaser)
'see art involved' is the wordplay.
'involved' indicates anagramming the letters (involved can mean confusing or complex).
'see'+'art'='seeart'
'seeart' anagrammed gives 'TEASER'.
'in' is the link.
(Other definitions for teaser that I've seen before include "One who pulls someone's leg" , "Hard question" , "Tricky question; intriguing preliminary advert" , "Conundrum" , "Difficult problem concerning Easter" .)
