"Ghosts” playwright (5)
I believe the answer is:
ibsen
'ghosts playwright' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ibsen that I've seen before include "Norwegian playwright, d. 1906" , "'Doll's House' playwright" , "Playmaker" , "Is Ben a playwright?" , "foreign author" .)
