In Hololulu Credlin found some wealth (5)
I believe the answer is:
lucre
'some wealth' is the definition.
(I've seen this before)
'in hololulu credlin found' is the wordplay.
'found' indicates the answer is hidden within the clue.
'LUCRE' can be found hidden inside 'in hololulu credlin'.
(Other definitions for lucre that I've seen before include "Cash" , "benefits from crime" , "financial gain" , "Sordid gain; riches" , "Ulcer (anag)" .)
