Discovered writer's home (4)
I believe the answer is:
crib
'home' is the definition.
(informal term for someone's home)
'discovered writer's' is the wordplay.
'discovered' says to take the centre (dis-covered - outer letters removed).
'writer' becomes 'scribe' (scribe is a kind of writer).
The centre of 'scribe' is 'CRIB'.
(Other definitions for crib that I've seen before include "Poor translation" , "Nativity scene; copy illicitly" , "Cot - copy another's work" , "A model of the manger" , "Baby's bed" .)
