"Doctor Zhivago" author (9)
I believe the answer is:
pasternak
'doctor zhivago author' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for pasternak that I've seen before include "novelist" , "Russian writer" , "Boris -, Doctor Zhivago author" , "Boris, perhaps" , "He declined Nobel prize" .)
