"Siddhartha” author (5)
I believe the answer is:
hesse
'siddhartha author' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hesse that I've seen before include "German state, capital Wiesbaden" , "Hermann --, German writer" , "Hermann --, German author" , "poet" , "Ger. state; Hermann ---, novelist" .)
