Now and then amazing things are done on this great stage of ours: lights go down; the back drop, which had given the illusion of solidity, reveals itself transparent. A sort of fairyland transformation takes place. Beyond the once solid wall strange figures move on -- a new mise en sc?ne, with the old blotted out in darkness. The lady, whom we left knitting by the fire, becomes a fairy -- Sara Lee became a fairy, of a sort -- and meets the prince. Adventure, too; and love, of course.
