Story of a wrought iron case (8)
I believe the answer is:
scenario
'story' is the definition.
(I know that scenario is a type of book)
'a wrought iron case' is the wordplay.
'a wrought' indicates an anagram (I've seen this in other clues).
'iron'+'case'='ironcase'
'ironcase' anagrammed gives 'SCENARIO'.
'of' is the link.
(Other definitions for scenario that I've seen before include "expected sequence of events" , "Storyline" , "Envisaged situation" , "Written outline of film, etc" , "play's outline" .)
