"Twilight" vampire (6)
I believe the answer is:
edward
'twilight vampire' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for edward that I've seen before include "Ted" , "Regnal name of six kings of England" , "-- Scissorhands" , "Sir -- Elgar, composer" , "Male name" .)
