Sleep in hovel right behind deserted bathhouse (7)
I believe the answer is:
slumber
'sleep' is the definition.
(I know that sleep can be written as slumber)
'hovel right behind deserted bathhouse' is the wordplay.
'hovel' becomes 'slum'.
'right' becomes 'r' (common abbreviation).
'behind' is a charade indicator (letters next to each other).
'deserted' suggests removing the centre (middle letters must vacate or desert the word).
'bathhouse' with its centre taken out is 'be'.
'r' put after 'be' is 'ber'.
'slum'+'ber'='SLUMBER'
'in' is the link.
(Other definitions for slumber that I've seen before include "snores, maybe?" , "Drop off" , "Snooze" , "repose" , "Doze" .)
