The Monster of Florence, which was shortlisted for the prestigious CWA Gold Dagger Award for Non Fiction in 2010, is a true account of brutal serial murder in idyllic Florence. After settling in Italy in 2000, Douglas Preston discovered that the olive grove in front of his family's new home had been the scene of one of the most infamous double-murders in Italian history, committed by a serial killer who had never been found and was known only as the Monster of Florence. Preston, intrigued, met Italian journalist Mario Spezi, who had followed the case since the first murders in 1974, to learn more.

This is the true story of their search for - and identification of - the man they believe committed the crimes, and their chilling interview with him. It's also the story of how Preston and Spezi themselves became embroiled in the case. Like one of Preston's bestselling thrillers, The Monster of Florence tells a gripping and harrowing story of murder, mutilation, suspicion and ruined lives - and at the centre of it, two brave writers trying to uncover the truth at all costs. This latest edition includes an explosive afterword about the much-publicised murder of a British student, Meredith Kercher, and its connection to the monster case.
