This is a book that has the advantage of lots of pictures, if you like looking at those kinds of thngs.
This is a book that is written about Ed Gein (the basis for "Psycho", "Texas Chainsaw Massacre," and "The Silence of the Lambs" [think clothing made of flesh]), and attempts to put the book in the setting of its day. It reads more like a novel than like a dry, facts-only book. I recommend the author if you have a curiosity about what makes people snap. Not sure it gives answers, but it gives hints, at least.
