Hector Hugh Munro - kind of monkey (4)
I believe the answer is:
saki
I believe this clue is a double definition.
'hector hugh munro' is the first definition.
(I've seen this in another clue)
'kind of monkey' is the second definition.
(I know that saki is a type of New World monkey)
(Other definitions for saki that I've seen before include "Pen name of short story writer, H.H. Munro, d. 1916" , "Pen-name of Hector Hugh Munro, d. 1916" , "drink in Tokyo" , "Japanese alcoholic drink made from rice" , "Scottish writer" .)
