Episodic story (6)
I believe the answer is:
serial
'episodic story' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for serial that I've seen before include "Publication in instalments" , "Consecutive, sequential" , "Continuous, perhaps like mulitple killer ( 6)" , "Soap opera, e.g." , "Continuous story set in Israel" .)
