Crossword Genius

Tool returned for money (4)

Ross

I believe the answer is:

loot

Here is my best explanation:

'money' is the definition.
(I've seen this before)

'tool returned' is the wordplay.
'returned' says the letters should be written in reverse.
'tool' in reverse letter order is 'LOOT'.

'for' is the link.
