Do they indicate that crime does pay? (5,2,3)

'do they indicate' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'crime does pay?' is the wordplay.
I cannot quite see how this works, but
'crime' could be 'sin' and 'sin' is found within the answer.
'pay?' could be 'wages' (I've seen this before) and 'wages' is present in the answer.
The remaining letters 'of' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'that' acts as a link.

Can you help me to learn more?
