Who killed Martina Magnani, a young high school student, found a corpse dressed as a witch, on the west beach of Cesenatico the following morning Halloween?
For the Piedmont Attanasio Pavone there is no doubt: the culprit is a Senegalese homeless man caught sleeping a few hundred meters from the victim, with his handbag next to him. The motive is clear: murder for the purpose of robbery after a likely attempt at violence.
But for Anna Bonoli, called the Lynx, a private detective with a past as an inspector of the State Police and a strong propensity for Gin Monkey47, things could have gone differently. It was she who found the girl's body and, from what she could observe by looking around, the accounts do not return.
Although the magistrate threatens to have her arrested for obstruction of the investigations if she only tries to take an interest in the case, the Lynx decides to investigate in parallel with her former colleagues, discovering that Martina was not at all an unwary high school student and her death actually hides many shadows.
