Established writer comes in to land, do we hear? (8)
I believe the answer is:
orthodox
'established' is the definition.
(similar in meaning)
'writer comes in to land do we hear?' is the wordplay.
I cannot really see how this works, but
'do' is found in the answer.
This explanation may well be incorrect...
(Other definitions for orthodox that I've seen before include "Standard" , "Conforming with established opinions" , "Traditional" , "Conforming with established doctrine" , "Regular - conventional" .)
