Corso returns to Spain to confront Borja. "Irene" insists that she is a fallen angel who has wandered the earth for millennia searching for him. Corso does not question this, and finds himself even more strongly attracted to her. He accuses Borja of being responsible for both murders. Borja, intending to use the ritual described by the book's true nine plates to summon the Devil and gain ultimate knowledge, has destroyed his entire library to prevent others from following his lead. Corso demands payment, but Borja ignores him and begins the ritual. Corso leaves in disgust; as he leaves, he hears Borja's screams of anguish as the ritual goes awry, remembering the Ceniza Brothers' discourse on false books and realizing one of the plates is a forgery. He joins "Irene" outside, and surmises that each of them will get the devil they deserve.
