Search for missing note in cabin (3)
I believe the answer is:
Here is my best explanation:
'cabin' is the definition.
'search for missing note' is the subsidiary indication.
'search for' becomes 'hunt' (I've seen this before).
'missing' is a deletion indicator.
'note' becomes 'n' (abbreviation).
'hunt' with 'n' taken out is 'hut'.
'in' is the link.
(Other definitions for hut that I've seen before include "Small shelter as for watchman", "Simple dwelling", "Small structure as for watchman", "Small roughly-made house or shelter", "Peter Nissen's ubiquitous structure", "'Shack, hovel (3)'", "Shed", "Small shed for storing, say, garden tools", "Small crude dwelling" and "Shanty".)
