Short piece from Pinter series (5)
I believe the answer is:
terse
'short' is the definition.
(synonyms)
'piece from pinter series' is the wordplay.
'piece from' says the answer is hidden in the clue.
'TERSE' is hidden in the letters of 'pinter series'.
(Other definitions for terse that I've seen before include "Short and to the point" , "Sententious" , "Short and sharp" , "Brusque, concise" , "precise" .)
