Money's in hiding place (as auditor perceives it) (4)
I believe the answer is:
cash
'money's' is the definition.
(cash is a type of money)
'hiding place as auditor perceives it' is the wordplay.
I cannot quite understand how this works, but
'as' is within the answer.
The remaining letters 'ch' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for cash that I've seen before include "Till" , "Brass" , "Ready money" , "notes, perhaps?" , "bread" .)
