Care to wander round British city in novel (7)
I believe the answer is:
Here is my best explanation:
'novel' is the definition.
'care to wander round british city' is the subsidiary indication.
'to wander' indicates an anagram.
'round' is an insertion indicator.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'city' becomes 'ec' (the City of London postcode).
'care' is an anagram of 'reca'.
'reca' enclosing 'bec' is 'rebecca'.
'in' is the link.
(Other definitions for rebecca that I've seen before include "Daphne du Maurier book; girl's name", "Mother of Jacob and Esau", "Daphne du Maurier's antiheroine", "Du Maurier novel - Hitchcock thriller", "The first Mrs de Winter (du Maurier)", "Novel by Daphne du Maurier", "The first Mrs de Winter (Du Maurier)", "One of the four matriarchs of the Jewish people (anglicised)", "Daphne du Maurier novel; girl's name" and "Girl's name - mother of Jacob and Esau".)
