The Monster of Florence by Douglas Preston with Mario Spezi (NF)

The Monster of Florence


Did you know that Italy had its own serial killer? Or that Thomas Harris was inspired by those murders when he wrote the sequel to the uber successful Silence of the Lambs, Hannibal? Let me introduce you to II Mostro or The Monster of Florence.

The Monster murdered 16 people in the province of Florence from 1968 to 1985 and he has never been tried for his crimes. Unfortunately, a few other men were tried, but they were not II Mostro and many men, families, and careers were destroyed during these.


Douglas Preston sort of stumbled into learning of the story when he moved to Florence in August of 2000 to work on a new book. It turns out that the house that he rented for his family just happens to be next to the olive grove that was one of the murder sites. Preston, a well know thriller writer, is intrigued and by meeting the journalist that covered II Mostro for more than twenty years, Mario Spezi, he ends up becoming part of the story himself.

II Mostro murdered lovers. He shot both dead and then usually dragged the woman’s body off a ways and took a biological trophy from her, leaving her exposed almost in a ritualistic fashion. In Italy, courtship rituals are a wee bit different from here in the US, young people live with their families until they are married, so where are loving couples going to go when they are desirous of a bit of one-on-one time? They take their cars and find quiet semi sheltered back-roads often near olive groves or vineyards that provide great views of the Florentine valley and most importantly, privacy.


This practice didn’t shock me at all, but a cottage industry that it spawned did. It seems that there is a whole group of men, called Inidiani, would creep around in the dark like peeping toms to watch these young lovers. Can you imagine? They had specific spots where they liked to watch and many even brought along night vision goggles and cameras to get better angles and just maybe something to blackmail adulterers with!

Anywho, when Preston gets into the story, there hadn’t been a murder since 1985, yet police were still busy investigating and pointing fingers and that suspect or another with craze and lack of evidence so much so that they reminded me of a Peter Sellers caper movie. You see, there are the police, then there are the carabinieri (military police), different prosecutors, and magistrates are all involved in the case and that makes for a big fat mess if you ask me.

For the book, Spezi catches Preston up by telling him everything that has happened so far and then the work on finding the killer together. They seem to think that the killer lies down in a direction that had long been considered closed by the police. The police and magistrates are off chasing leads and creating flimsy facts looking into a vast conspiracy of rich satanic worshippers. I kid you not, they are ready to arrest pretty much every nobleman in the province as being a member of a satanic cult.

It hits the fan when the police get tired of Preston and Spezi saying that the police are on the wrong trail. Italian men are proud men and they don’t like to be told that they are wrong. Next thing you know, Preston and Spezi are indicted and Spezi is then suspected as being II Mostro.

My thoughts-

This is true crime like no other and what made it more interesting was that it takes place in Italy. Not only do we get to read beautiful descriptions of Florence, we get to peek inside how the Italian Justice system works…..or doesn’t work in this case. I hate to judge how another county runs things, but the way they do it isn’t in no way efficient and in this case, seldom leads to justice. It is like a bunch of clowns took over and the attending media add to the circus atmosphere.

It should be no surprise that I couldn’t put the book down. I wanted to know who II Mostro was and just couldn’t fathom the lengths that the legal system would go to in order to push their theories of the case ahead, no matter how out there they were.

Of special interest was how they could turn on journalists, whose job it is to investigate and report the story to the masses. That aspect of the story had journalists all over the world crying foul, just as it should have.

Brava Douglas Preston and Mario Spezi!

  1. Though I’ve seen this book around, I had absolutely no clue what it was about — or that it was actually a true story! And since I read every word of your review, sounds like something that would captivate me. I love Italy, too, so that setting would be great.

  2. I am a true crime junkie, and knowing this, my husband bought me this book. It blew my mind! What a damn fine mess this all was. Interestingly, what started out as a story about a serial murderer spirals into a statement about the homicide investigators in Italy. Personally, it spooked me out and I made a mental note to never visit there (or if I did, then I’d better not be in the wrong place at the wrong time!).

  3. The cover absolutely gives me the creeps. I used to read true crime a long time ago and then I realized it could happen to me!!! Sounds like a captivating read!

  4. I was thinking the same thing, don’t ever want to get caught in that legal system. It is horrible and takes forever to wade through!

  5. The “it could happen to me” factor is lessened in this one because there hasn’t been a II Mostro murder since 1985. The book focusses less on the murders and more on the crazy way that Italy investigates and tries their cases. Still scary, but not death like scary:)

  6. I listened to this one last year, and will never forget where I was when I was starting this audiobook – at the gym, on the treadmill – when they start describing this really grisly disgusting crime scene. I nearly lost my footing and started panting hard. What a horror! And I had to double check that it was NF not fiction. I somehow lost interest in the second half because I didn’t find the way the plot line moved from one to the other synchronized, but well, I am no big audio book fan either, so I’ll blame that.

  7. Night vision goggles in the 60’s, 70’s and 80’s? Really?

    Night vision goggles were/are extremely expensive and weren’t created until the 1990’s by the U.S. military and weren’t available to the public until many years later.

    The night vision devices that came before the invention of the goggles were large, heavy devices mounted to tanks and other vehicles.

    So, there’s no way a “peeping tom” would be running around in the vineyards with night vision in the days that the murders occurred.

  8. Actually, Night vision goggles were used as early as WWII. They weren’t great and have improved by leaps & bounds, but they were around. By the Vietnam War, they were small enough to be used as sniperscopes. By the mid 1980’s, they were totally portable and honest to goodness goggles.
