Bad boy’s two homes (7)
I believe the answer is:
villain
'bad boy's two homes' is the definition.
I can't tell whether this defines the answer.
'two homes' is the wordplay.
'two homes' can mean two substitutions for 'home'.
'home' becomes 'villa' (I've seen this before).
'home' becomes 'in' ('he's home' can mean 'he's in').
'villa'+'in'='VILLAIN'
Can you help me to learn more?
(Other definitions for villain that I've seen before include "Scoundrel" , "Criminal, rogue" , "Evil character" , "Evil-doer" , "One played badly" .)
