Fraud with numbersof Romans taken in by bad man (7)
I believe the answer is:
swindle
'fraud' is the definition.
(a swindle is a fraud or con)
'with numbersof romans taken in by bad man' is the wordplay.
I cannot quite see how this works, but
'with' could be 'w' (short for with) and 'w' is located in the answer.
'in' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for swindle that I've seen before include "Fraudulent action" , "fleece" , "skin" , "Ramp" , "Trick" .)
