Pigeonhole's place (4)
I believe the answer is:
desk
'pigeonhole's place' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for desk that I've seen before include "Writing-table" , "Writer's workbench" , "Table for writing, reading etc" , "Piece of furniture for writer" , "School furniture item" .)
