Professor Liu Taylor's notes were only given to Kiara, and Kiara's notes to Isaac, yet this mysterious person gave such important material to Kiara.
The cases recorded in the document were so impressive that Kiara could tell the person who wrote this was of an exceptionally high level, even better than Professor Liu Taylor!
The cases included analyses of some major world incidents, and being involved in this research meant that the person sending the emails had a status definitely above the ordinary, with resources that even Professor Liu Taylor couldn't match.
A large part of Kiara's troubles were suddenly resolved, and she repeatedly went over the document no less than ten times, feeling more and more that there was so much she could learn from it.
The level of a doctor, especially a psychologist, is built up by one case after another, figuring out their own set of rules through practice.
