A Writer's Room?

This wee room with the foxhunting wallpaper is purported to be where R L Stevenson wrote Treasure Island and it is true that the window on the right looks over to the Island of Fidra which is one of the islands that RLS is thought to have based the map of Treasure Island on but in fact RLS was only down by North Berwick during his childhood where he played on the beaches and shore  around this area.
