Place us over the queen's employers (5)
I believe the answer is:
users
'employers' is the definition.
(I've seen this before)
'place us over the queen's' is the wordplay.
I cannot really see how this works, but
'us' is found in the answer.
'queen's' could be 'ers' (abbreviation for Elizabeth Regina) and 'ers' is found in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for users that I've seen before include "People who take drugs" , "Operators" , "Drug addicts" , "Customers" , "They employ" .)
