I know full well that finding secret codes is a favorite pastime for obsessives, conspiracy-theorists, charlatans with a eye to the main chance, et hoc genus omne [and everything of this kind]; it has been unwittingly satirized in Dan Brown’s blockbusting thriller, The Da Vinci Code. Occasionally, however, a sober critic, paying close attention to a text, will make an interpretive discovery and produce a bona fide ‘code breaking’ work. – Michael Ward, Planet Narnia
