Review on book ...
Reading between the lines we can see that John Ramsey himself is a slightly "superior," somewhat cold and calculating man with some prejudice against the relatively liberal culture of Boulder, Colorado and against the poor (see page 690 where he argues that Bill McReynolds, who played "Santa Claus," should be a suspect partly because "he doesn't have two nickels to rub together"). Nonetheless one imagines that John Ramsey loved his daughter (and she loved him) so that it is untenable to think that he could have deliberately
murdered her. Furthermore he has too much control of himself to have accidentally struck and killed her. On the other hand Patsy Ramsey comes across as someone with particularly shallow values predicated almost entirely on appearance who has a temper that she could very well lose. Her love for her daughter is less clear than her husband's, although her need for JonBenét to succeed and thereby reflect favorably upon herself is very strong. One imagines that she could punish her daughter very severely but outside of public scrutiny. One further imagines she would seek to cover up anything that would make her look bad. One very telling observation in the book (p. 13) is that the ransom note was the "War and Peace of ransom notes."
The Patsy Ramsey seen in this book is a person who does everything in a flamboyant and overdone manner.
I don't think, however, that the evidence as presented here is strong enough to draw a definite conclusion about who killed JonBenét. One thing is clear: John and Patsy Ramsey are either monstrously unlucky, or they are monsters.
