Italian quietly breaking in to steal carp (3-4)

I believe the answer is:

nit-pick

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

'italian quietly breaking in to steal' is the wordplay.
'italian' becomes 'it' (abbreviation for Italian).
'quietly' becomes 'p' (p for piano and quiet).
'breaking in' indicates putting letters inside.
'to steal' becomes 'nick' (nick can informally mean to steal).
'it'+'p'='itp'
'itp' put into 'nick' is 'NIT-PICK'.

I've seen this clue in The Telegraph.
