“While this book is marketed as a true story, there are many doubts to it's authenticity. There are many that truly believe these events took place and others who claim the Lutzes manufactured the story of the Amityville house for monetary gain. When I started this story, I put it's truthfulness at the back of my mind and simply read the story as if it were pure fiction.
As a fiction work, I really enjoyed this book. The back story of the house is creepy enough with the DeFeo murders. Then you have this nice family that moves in and all kinds of craziness begins to happen in the house. You have everything you need for a good creepy haunted house story: history of murder, disembodied voices, music coming from nowhere, things moving, etc... This story is really compelling and it's very hard to put down.
On the nonfiction side, it's a little unbelievable. I can grasp the disembodied voices, things moving, etc., but I can't grasp the green slime coming from the walls or the levitation of Mr. and Mrs. Lutz. Whether any of it is true or not, I can't say. Which is why I would rather look at it from a fictional point-of-view.
If you are looking for a really creepy haunted house story, pick up a copy of The Amityville Horror. You won't be disappointed.
