Bug, silent, wrecked home (6,2)
I believe the answer is:
listen in
'bug' is the definition.
(thesaurus)
'silent wrecked home' is the wordplay.
'wrecked' indicates an anagram.
'home' becomes 'in' ('he's home' can mean 'he's in').
'silent' anagrammed gives 'listen'.
'listen'+'in'='LISTEN IN'
(Other definitions for listen in that I've seen before include "Eavesdrop" , "Overhear conversation as on phone (6, 2)" , "Wire-tapper will" .)
