Writer's place for putting in speech (6)
I believe the answer is:
greene
'writer's' is the definition.
(graham greene)
'place for putting in speech' is the wordplay.
'place for putting' becomes 'green' (I've seen this in another clue).
'in speech' indicates a 'sounds like' (homophone) clue.
'green' sounds like 'GREENE'.
(Other definitions for greene that I've seen before include "The Quiet American author" , "Graham --, British author" , "Graham --, Eng. author" , "writer" , "See 13" .)
