Accountant might go astray, getting nothing for house in Marino (6)
I believe the answer is:
casino
'house in marino' is the definition.
I can't judge whether this definition defines the answer.
'accountant might go astray getting nothing' is the wordplay.
'accountant might' becomes 'ca' (I can't justify this - if you can you should give a lot more credence to this answer).
'go astray' becomes 'sin' (I've seen this in another clue).
'getting' is a charade indicator (letters next to each other).
'nothing' becomes 'O' (looks like zero - 0).
'ca'+'sin'+'o'='CASINO'
'for' is the link.
Can you help me to learn more?
(Other definitions for casino that I've seen before include "where one can lose a lot of money" , "You can win a fortune here" , "Building for gambling" , "Gambling establishment" , "Where one may gamble" .)
