The monster of Florence, by Douglas Preston and Mario Spezi

Preston recounts the actions he and Spezi took to investigate the murders and mutilations perpetrated by "Il Mostro", who was used in part to build the character of Hannibal Lecter. Neither the authors nor the police discover who committed the crimes, but enough of the mystery was recounted to make it interesting. It is also offered some quirky details of life and culture in Tuscany and Italy, including an surprise peek into the voyeur subculture of Florence.
