Because transgress also means dying… A rich and voluptuary businessman from Bologna is found dead in his luxurious villa near the Margherita gardens. The investigations of the mobile team in Bologna make it possible to determine that this is a homicide. From the toxicological tests it emerges that someone has poisoned the licentious playboy. The reporter Saru Santacroce follows the investigative work to give a name to the murderer. Thanks to his knowledge and a good dose of luck, Saru always has something more than other colleagues. But it is difficult to work when the needs of the investigators and those of the media circus do not match. The police find out that the victim’s private life is at high erotic tension. In fact, the man attends club privé, organizes orgies in his villa and loves to experiment with new areas in the same way as the Marquis De Sade. The service woman who has always known him has a different idea of that man she is in love with. The other female protagonist of this thriller knows well that together with him lives the transgression in all its nuances, even the most unspeakable ones. She would like a stable relationship with him, but she discovers that she is only a pawn to satisfy animal instincts. Her husband, a lawyer above suspicion, appreciates the game of transgression and animates him by throwing her into the arms of other men. It is difficult for the police to find out who murdered the man from the dark past who does business even with organized crime. In this mystery, Saru Santacroce proves to know well the world of transgression. A universe that lives and describes with an abundance of often strong and erotic-intensive details. And it reveals all the background of a reality that the unique thought, voyeur and itchy, defines corrupt, perverse and sick. And if transgressing also means dying, it is still a world that is only the reflected image of what we are and what we probably dream of. But without having the courage to live it for real. Because, as Saru explains, paraphrasing Jung, libido is not just a sexual drive as defined by Freud. It is a psychic energy that gives the man a vital impulse that goes beyond the only sexual sphere, gaining the value of a real spiritual transformation.
