The author presents a detailed claim that a bi-literal cipher embedded in early printed italic type was deliberately used to conceal alternative historical documents and dramas within a major Renaissance author's works. The book explains the ciphering method, supplies keys and facsimiles, and offers deciphered texts and dramatic reconstructions, accompanied by explanations, replies to critics, and appendices documenting editions and procedures. It also advances controversial readings asserting secret biographical and political disclosures, and situates the bi-literal method as a key to a broader word-cipher purported to preserve concealed historical narratives.
