Restraint boxer needs in Castle Ashby? (5)
I believe the answer is:
leash
'restraint' is the definition.
(leash is a kind of restraint)
'in castle ashby?' is the wordplay.
'in' says the answer is hidden in the clue.
'LEASH' can be found hidden inside 'castle ashby'.
'boxer needs' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for leash that I've seen before include "Restraining strap for dog" , "Strap for holding a dog while walking" , "Animal restraint" , "Restraint for a dog" , "(Dog's) lead" .)
