A blind woman leads her Naples police colleagues through the darkness in this distinctive crime thriller.   A report has landed on Commissario Martusciello’s desk. The lifeless body of the singer Jerry Vialdi—aka Gennaro Mangiavento—has been found at the Naples football stadium; another corpse, this one a Jane Doe, has been discovered in the Bentegodi Stadium in Verona, hundreds of miles away.   The bodies were left in a fetal position and there are no signs of physical violence: The method and the madness behind it appear to hide some unutterable secret. Conclusion: a daring challenge left by a psychopath for the police—who are stabbing in the dark with no idea where to begin. All except for superintendent Blanca Occhiuzzi: Beautiful, blind from birth, forced by the dark that envelops her to perceive the world through only four senses, she feels the fear in people; she feels their guilt and their innocence. It is she who takes Martusciello by the hand, guiding him into the mind of a murderer . . .
