While the short, lethal careers of serial killers such as Jeffrey Dahmer and Andrew Cunanan terrorize the public and provide morbid inspiration for the entertainment industry, few people realize that it is the female serial killer, seldom heard of, who deserves most to be feared. Murder Most Rare provides startling information about the female serial murderer, who is shown to be far more deadly and determined, difficult to apprehend, and complexly motivated than her male counterpart. While serial murder by women is relatively rare, a surprising number of female serial killers are identified by the authors, nearly 100 in this century, with half of them having committed their crimes in America. By examining these women's backgrounds, motives and methods of killing, the book sheds new light on dozens of overlooked cases of murder and uncovers callous crimes and passions gone awry. After a thought-provoking exploration of the cultural biases that have caused us historically to dismiss and ignore the criminal potential of women, Murder Most Rare divides female serial murders for the first time into seven categories: Black Widow, Angel of Death, Sexual Predator, Revenge, Profit or Crime, Team Killer and Question of Sanity. These seven types vary widely in motivation, choice of victims, weapons and methods. The authors reveal patterns that occur within the types, but stress that the complicated nature of these women's crimes makes personality profiling almost impossible—a fact that causes the jobs of homicide investigators to be difficult, indeed, sometimes impossible. This is a uniquely personal look into a dark, shocking world.

California was thrown into a paralysis of fear in 1969, distraught over the unsolved murders of the Zodiac killer. The Zodiac became the most elusive and frustrating adversary ever encountered by the law enforcement community in the San Francisco Bay Area. A series of letters, allegedly written by the murderer himself and published in local newspapers, only added to the mystery and panic. Over 30 years after he exploded onto the headlines of the San Francisco Chronicle, the Zodiac serial killer remains an enigma that is unparalleled in the history of crime in America, and the case remains unsolved. Violence expert Michael Kelleher and psychologist David Van Nuys attempt to provide a glimpse into the mind of this mysterious murderer.

Kelleher and Van Nuys reconstruct the crime scenes, delve into the records, and psychoanalyze the Zodiac's letters to newspapers and the law enforcement agencies. The facts of the case and the fragmentary glimpses of the Zodiac's psychodynamics that came through his letters forced the authors, reluctantly, to draw a conclusion that is sure to be controversial-namely, that the Zodiac suffered from multiple personality disorder. They also debunk many popular legends and myths about the case, laying out the limited facts that we do have on the notorious Zodiac.
