Tennyson heroine to eat in style after retiring (4)
I believe the answer is:
enid
'tennyson heroine' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for enid that I've seen before include "Geraint's wife's" , "& 18 Down Children's author" , "Dine with this girl" , "Geraint's loved one" , "Lady" .)
