Succeed in returning debt and retire here? (4,3)
I believe the answer is:
twin bed
'retire here?' is the definition.
(you might sleep or retire in a bed)
'succeed in returning debt' is the wordplay.
'succeed' becomes 'win' (succeed can mean to win or excel).
'in' indicates putting letters inside.
'returning' is a reversal indicator.
'debt' written backwards gives 'tbed'.
'win' inserted inside 'tbed' is 'TWIN BED'.
'and' is the link.
(Other definitions for twin bed that I've seen before include "place for retirement" , "This may be found in a double room" , "One of a matching pair in a room for two" , "One of a pair to sleep on" .)
