Booker Prize winner in demand before university called foul (5,2,3)
I believe the answer is:
hotel du lac
'booker prize winner' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'demand before university called foul' is the wordplay.
'demand before' becomes 'hot' (I can't justify this - if you can you should believe this answer much more).
'university' becomes 'u' (abbreviation for university).
'foul' indicates an anagram.
'u'+'called'='ucalled'
'ucalled' with letters rearranged gives 'eldulac'.
'hot'+'eldulac'='HOTEL DU LAC'
'in' is the link.
Can you help me to learn more?
(Another definition for hotel du lac that I've seen is " LITERATURE".)
