Epistle from landlord? (6)
I believe the answer is:
letter
I believe this is a double definition.
'epistle' is the first definition.
(I know that epistle can be written as letter)
'landlord?' is the second definition.
(landlords let property)
'from' is the link.
(Other definitions for letter that I've seen before include "Item sent - character" , "It's one of twenty-six" , "Alphabetic symbol" , "A written form of communication" , "who may offer terms to residents?" .)
