The couple from Talbot House (4)
I believe the answer is:
both
'the couple' is the definition.
(I've seen this before)
'from talbot house' is the wordplay.
'from' says the answer is hidden in the clue.
'BOTH' is hidden within 'talbot house'.
(Other definitions for both that I've seen before include "Two considered together" , "Each of two (alternatives)" , "The two (things)" , "couple" , "The one and the other" .)
