Peer at home drinking tea, forming attachment to hunter? (5,5)
I believe the answer is:
watch chain
'attachment to hunter?' is the definition.
(hunter is a type of watch)
'peer at home drinking tea' is the wordplay.
'peer at' becomes 'watch' (to peer at is to watch or look at).
'home' becomes 'in' ('he's home' can mean 'he's in').
'drinking' means one lot of letters goes inside another.
'tea' becomes 'cha' (cha is a type of tea).
'watch'+'in'='watchin'
'watchin' going around 'cha' is 'WATCH-CHAIN'.
'forming' acts as a link.
(Other definitions for watch chain that I've seen before include "linked to old timer" , "Fob" .)
