In a world where wizards, vampires and evil spirits live side by side with human beings, “Diana Bishop” is the last survivor of the generations of prominent magicians. He has no interest in this heritage and prefers to dip himself into his work of history and focus only on the study of history. He is interested in alchemy, goes to Oxford some days and studies the works of Elias Schmüll. Until one day he calls “Schmall 782” for study. But as soon as he receives it, he realizes that something is weird; when it opens up, he gets shocked. He is surrounded and threatened, and he knows very well that all the mysteries of this work must be found to protect himself.
When he hits with Matthew, who is a vampire, Matthew offers him a suggestion. But both know very well that wizards and vampires must never trust each other.
