Three, imperfect number - Patrizia Rinaldi

The lifeless body of Neapolitan singer Jerry Vialdi has been found at the Naples football stadium; another corpse, this time an unidentified woman, has been discovered in the Bentegodi Stadium in Verona. They were left with no signs of violence: the method and the madness point to a daring challenge for the police, who has no idea where to begin. All except for Superintendent Blanca Occhiuzzi: beautiful, blind from birth, forced by the dark that envelopes to perceive the world through four senses, she feels the fear in people, their guilt and their innocence.
