Parents need to know that the main character, Alexander T. Wolf, tells his version of the "Three Little Pigs" story from prison. (He's accused of killing and eating two of the three pigs.) The wolf presents his side of the story as the truth, but there's also the distinct possibility that he's lying. While adults will undoubtably draw larger lessons from this razor-sharp fairy tale parody, kids will probably just think it's funny.
Violence & scariness:It is mentioned that the wolf eats the pigs, though his eating takes place offstage.
