Port in Scott's "Lord of the Isles" (4)
I believe the answer is:
oban
'port in scott's lord of the isles' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for oban that I've seen before include "Port and holiday centre on the west coast of Scotland" , "Northern port" , "port required" , "Argyll and Bute resort" , "Scottish town" .)
