Something wrong with second home? (3)

Ross

I believe the answer is:

sin

'something wrong' is the definition.
(something morally wrong)

'with second home?' is the wordplay.
'with' is a charade indicator (letters next to each other).
'second' becomes 's' (common abbreviation).
'home?' becomes 'in' ('he's home' can mean 'he's in').
's'+'in' is 'SIN'.

(Other definitions for sin that I've seen before include "Wicked deed" , "Breach of moral code" , "grave offence" , "Pride, say" , "Serious offence" .)
