The Monster of Florence – The True Story Behind the Hit Netflix Series

From Douglas Preston, the #1 New York Times bestselling author of The Lost City of the Monkey God, comes a chilling true-crime masterpiece that inspired the hit Netflix series. The Monster of Florence is a gripping tale of murder, obsession, and a shocking miscarriage of justice in the beautiful hills of Tuscany.

In 2000, Douglas Preston moved his family to Italy, fulfilling a lifelong dream. But that dream quickly darkened when he learned that the olive grove outside their 14th-century farmhouse had once been the scene of a brutal double murder—one of a series attributed to Italy’s most infamous serial killer, known as The Monster of Florence.

Fascinated and horrified, Preston teams up with Italian journalist Mario Spezi to investigate the mystery. Their search for the truth leads them deep into Italy’s tangled legal system, where corruption, paranoia, and fear run rampant. In a shocking twist, both men become suspects in the very case they’re trying to solve—Preston is interrogated and forced to flee the country, while Spezi is imprisoned, accused of being the Monster himself.

The Monster of Florence reads like one of Preston’s thrillers, but every word is true. It’s a haunting journey through real-life horror, filled with murder, mutilation, betrayal, and the relentless pursuit of justice.

A true-crime classic that reveals the dark side of paradise—where the beauty of Florence hides secrets too terrifying to imagine.

Read the true story that captivated millions—and inspired the Netflix phenomenon.
