John, go you to my private cabinet in the palace--for none knoweth
the place better than you--and, close down to the floor, in the left
corner remotest from the door that opens from the ante-chamber, you
shall find in the wall a brazen nail-head; press upon it and a little
jewel-closet will fly open which not even you do know of--no, nor
any soul else in all the world but me and the trusty artisan that did
contrive it for me.
