See art involved in puzzle (6)
I believe the answer is:
teaser
'puzzle' is the definition.
(I've seen this before)
'see art involved' is the wordplay.
'involved' indicates an anagram (involved can mean confusing or complex).
'see'+'art'='seeart'
'seeart' with letters rearranged gives 'TEASER'.
'in' acts as a 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" .)
