!!This book has examples of:

* DramaticDrop: When a bartender learns that George Lutz lives in 112 Ocean Avenue, he is so shocked that he drops the empty beer glass from his hand, and it shatters on the floor.

* RedEyesTakeWarning: The pig-like demonic creature called Jodie had red glowing eyes, which Kathy sees staring at her at one point.
* VeryLooselyBasedOnATrueStory: The book was based not on direct interviews with the Lutz family, but on a series of disorganized audiotape recordings they'd made, for their own use, of themselves discussing their recollections of events. Author Jay Anson then had to piece together a readable novel out of this and some other research done on his part. He admitted to re-arranging, embellishing, or outright creating certain events in order to make for a coherent, scary story. As such, even he and the Lutzes admitted the book wasn't a completely factual account - though the Lutzes maintained it was the most accurate portrayal of their experiences ever published, for whatever that's worth.
