Domestic employee’s husband taking ring across river (11)
I believe the answer is:
housekeeper
'domestic employee's' is the definition.
(I've seen this before)
'husband taking ring across river' is the wordplay.
I cannot really understand how this works, but
'husband' could be 'house' (house husband is a kind of husband) and 'house' is found in the answer.
'ring' could be 'keeper' (I've seen this before) and 'keeper' is located in the answer.
No letters remain.
This explanation may well be incorrect...
(Other definitions for housekeeper that I've seen before include "Home manager" , "Domestic employee" , "Domestic manager" , "servant" .)
