I recalled novel about knight in rags-to-riches story (10)
I believe the answer is:
cinderella
'rags-to-riches story' is the definition.
(I've seen this in another clue)
'i recalled novel about knight' is the wordplay.
'novel' indicates an anagram (letters in a new or novel order).
'about' indicates putting letters inside.
'knight' becomes 'n' (chess abbreviation).
'i'+'recalled'='irecalled'
'irecalled' anagrammed gives 'ciderella'.
'ciderella' enclosing 'n' is 'CINDERELLA'.
'in' acts as a link.
(Other definitions for cinderella that I've seen before include "Ballet by Prokofiev" , "rags-to-riches tale" , "Pantomime heroine" , "One whose talent is overlooked" , "a success in the end?" .)
