About the book: 2018 / A maniac’s obsession is lethal for the victim. Is it fatal for me, the observer magician? I study the history of Jack the Ripper, going back a hundred years to follow him. I plunge into the darkness of the London slums, I see how the most famous serial killer kills women. I need the time of the unfortunate victims, the time that they would have lived if they had not died. Why do I need years of the dead? Give it to the scientific supervisor, a high necromancer who seems to have decided to live forever. Is the all-powerful teacher’s interest in me fatal? This is the most difficult and dangerous question.
