Dalle tenebre

In German universities, someone kills bloodily to take possession of an ancient text of black magic, the Grimoire "De Profundis", which centuries ago was dismembered into four parts due to its dangerousness. Under the guise of a vampirology professor, Harlan Draka investigates in Freiburg with the help of his friend Professor Milius. Thus he comes across the Guardian of the last part of the Grimoire, who has a pretty appearance, and his opponents, who are not pretty at all!
