One literally from the landlord? (6)
I believe the answer is:
letter
I believe this is a double definition.
'one literally' is the first definition.
(thesaurus)
'the landlord?' is the second definition.
(landlords let property)
'from' acts as a link.
(Other definitions for letter that I've seen before include "A, B or C, for example" , "Written message" , "Item sent - character" , "A written form of communication" , "Character - mail - landlord" .)
