One of Jane’s, her baby not unusually filled with rage (10,5)
I believe the answer is:
northanger abbey
'one' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see an association between them that I can't see?
'jane's her baby not unusually filled with rage' is the wordplay.
I cannot quite see how this works, but
'her' could be 'abbey' and 'abbey' is located in the answer.
'not' could be 'no' (I've seen this in other clues) and 'no' is located in the answer.
'rage' could be 'anger' (I've seen this before) and 'anger' is located in the answer.
This may be the basis of clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for northanger abbey that I've seen before include "book" , "Novel" .)
