Narrative excerpt (7)
I believe the answer is:
episode
'narrative excerpt' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for episode that I've seen before include "Part of a broadcast serial, say" , "Instalment of a TV series" , "Incident or event as part of sequence" , "Distinctive happening" , "Story instalment" .)
