Tricky question plucked from quite a series (6)
I believe the answer is:
teaser
'tricky question' is the definition.
(I've seen this before)
'plucked from quite a series' is the wordplay.
'plucked from' indicates a hidden word.
'TEASER' is hidden within 'quite a series'.
(Other definitions for teaser that I've seen before include "One who irritates playfully" , "Riddle" , "Puzzling question or gentle goader" , "You must be kidding!" , "Tricky question; intriguing ad" .)
