Married rogue in trouble remains here (6)
I believe the answer is:
morgue
'remains here' is the definition.
'married rogue in trouble' is the wordplay.
'married' becomes 'm'.
'in trouble' is an anagram indicator.
'rogue' is an anagram of 'orgue'.
'm'+'orgue'='MORGUE'
(Other definitions for morgue that I've seen before include "Mortuary" , "Our Meg (anag)" , "room kept cold!" , "Building where dead bodies are stored" , "Building for conducting postmortems" .)
