Oxford maybe has novel about love (4)
I believe the answer is:
shoe
'oxford maybe' is the definition.
(I know that oxford is a type of shoe)
'novel about love' is the wordplay.
'novel' becomes 'she' (novel by H Rider Haggard).
'about' indicates putting letters inside.
'love' becomes 'o' (love means zero in tennis).
'she' placed around 'o' is 'SHOE'.
'has' acts as a link.
(Other definitions for shoe that I've seen before include "Loafer, say" , "What one needs for a horse" , "Item of footwear" , "Box for holding and dispensing from pack of cards" , "Clothing item" .)
