Henry VIII's last wife (4)
I believe the answer is:
parr
'henry viii's last wife' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for parr that I've seen before include "Young salmon with spots" , "Fish" , "Henry's sixth (his third 7!)" , "Catherine --, Henry VIII's sixth wife" , "Young salmon or trout" .)
