The book deals with the criminal mind and why some people do the things they do. It is mostly about psychology and why some people turn out to be self-centered egomaniacs not caring for others as long as they get their gratification such as the two sons of a woman who wanted her to sign everything she has over to them and then be interned in some nursing home where she would most probably be abused by stall members not to mention the negligence. A month and half earlier, she suffered a debilitating stroke, but neither one of her sons came to see her in the hospital and never once called her to find out how she was. As the two sons were growing up, she and her husband became increasingly disappointed in them. The woman prayed for then to become less self-centered, but to no avail. She eventually became an atheist as did her husband. Another subject the book deals with is obsession and how it motivates some people do bodily harm as well as perpetrating murder. Finally, it deals with why some people act the way they do due to their upbringing such as why a nurse turned on her mother because her mother favored her older sister.
