Hide money for the audience (5)
I believe the answer is:
cache
'hide' is the definition.
(thesaurus)
'money for the audience' is the wordplay.
'money' becomes 'cash' (I've seen this before).
'for the audience' indicates a 'sounds like' (homophone) clue.
'cash' sounds like 'CACHE'.
(Other definitions for cache that I've seen before include "Hidden storage place" , "Collection of hidden things" , "Put away" , "Something hidden" , "Secret hiding place" .)
