The Monster of Florence

In 2000, novelist Douglas Preston moved to an Italian farmhouse, only to discover a double homicide had occurred on his property decades earlier. He teamed up with local investigative reporter Mario Spezi to identify the Monster of Florence, a serial killer who targeted couples in the Tuscan countryside between 1968 and 1985. Their investigation reveals how the Italian legal system focused on Satanic cult theories and fringe conspiracies rather than forensic evidence. The narrative details the subsequent harassment of the authors by the police, leading to Spezi’s imprisonment and Preston’s interrogation for obstruction of justice.
