A Shop in Go-By Street [EPUB ebook] 

And so I came to be directed to the shop of a dreamer who lives not far from the Embankment in the City. Among so many streets as there are in the city it is little wonder that there is one that has never been seen before; it is named Go-by Street and runs out of the Strand if you look very closely. Now when you enter this man’s shop you do not go straight to the point but you ask him to sell you something, and if it is anything with which he can supply you he hands it you and wishes you good-morning. It is his way. And many have been deceived by asking for some unlikely thing, such as the oyster-shell from which was taken one of those single pearls that made the gates of Heaven in Revelations, and finding that the old man had it in stock.
