Mario Spezi is a Florentine crime journalist who has co-written a book with Douglas Preston on the Monster of Florence. Spezi was imprisoned last month for ‘sidetracking the investigation’ of one of the most expensive, notorious criminal cases in Italian history. An independent three judge panel annulled the imprisonment and ordered his immediate release due to lack of evidence after 23 days in jail. He was set free unconditionally. Spezi has written various thrillers including Il passo dell’orco and Il violinista verde. His most recent novel Dolci Colline di Sangue has recently been published in Italian.
