Holiday accommodation ultimately rented by male French writer (13)
I believe the answer is:
chateaubriand
'french writer' is the definition.
(I've seen this before)
'holiday accommodation ultimately rented by male' is the wordplay.
I cannot really see how this works, but
'by' could be 'at' and 'at' is present in the answer.
'male' could be 'ian' (I've seen this before) and 'ian' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for chateaubriand that I've seen before include "Fr. writer; fillet steak" , "portion of meat" , "French author" , "Thick beef steak fillet" , "cut" .)
