Noted short-story writer (4)
I believe the answer is:
'noted short-story writer' is the definition.

This is all the clue.
(Other definitions for saki that I've seen before include "refreshment for Orientals" , "Pen-name of Hector Hugh Munro, d. 1916" , "author chosen by 29" , "Pen name of short story writer, H.H. Munro, d. 1916" , "Japanese rice wine" .)
