It's paid us to return to Brideshead (3)

I believe the answer is:
sub
'it's paid' is the definition.
I can't tell whether this definition defines the answer.
'us to return to brideshead' is the wordplay.
'to return' shows that the letters should be reversed in order.
'to brideshead' becomes 'b' (head letter of 'brides').
'us' in reverse letter order is 'su'.
'su'+'b'='SUB'
Can you help me to learn more?
(Other definitions for sub that I've seen before include "Junior editor" , "Prefix meaning under or lower" , "Replacement" , "Loan" , "Prefix meaning beneath" .)
