Novel about love in Oxford? (4)
I believe the answer is:
shoe
'oxford?' is the definition.
(oxford is a kind of shoe)
'novel about love' is the wordplay.
'novel' becomes 'she' (novel by H Rider Haggard).
'about' means one lot of letters goes inside another.
'love' becomes 'o' (love means zero in tennis).
'she' enclosing 'o' is 'SHOE'.
'in' is the link.
(Other definitions for shoe that I've seen before include "Clothing item" , "Case from which playing cards are delt one at a time" , "Eg, brogue" , "9 maybe" , "Footwear - playing-card dispenser - part of a brake" .)
