Search for missing note in cabin (3)
I believe the answer is:
hut
'cabin' is the definition.
(thesaurus)
'search for missing note' is the wordplay.
'search for' becomes 'hunt' (I've seen this before).
'missing' suggests deleting specific letters.
'note' becomes 'n' (abbreviation).
'hunt' with 'n' removed is 'HUT'.
'in' is the link.
(Other definitions for hut that I've seen before include "Small shelter as for watchman" , "Small wooden shelter" , "Small shed for storing, say, garden tools" , "Simple building" , "Small structure as for watchman" .)
