There is little more terrifying than those who hunt, stalk and snatch their prey under the cloak of darkness. These hunters search not for animals, but for the touch, taste, and empowerment of human flesh. They are cannibals, vampires and monsters, and they walk among us.

These serial killers are not mythical beasts with horns and shaggy hair. They are people living in society, going about their day-to-day activities until nightfall. They are the Dennis Rader's, the fathers, husbands, church-going members of the community.

This A-Z encyclopedia of 150 serial killers is the ideal reference book. Included are the most famous true crime serial killers, like Jeffrey Dahmer, John Wayne Gacy, and Richard Ramirez, and not to mention the women who kill, such as Aileen Wuornos and Martha Rendell. There are also lesser-known serial killers, covering many countries around the world, so the range is broad.

Each of the serial killer files includes information on when and how they killed the victims, the background of each killer, or the suspects in some cases such as the Zodiac killer, their trials and punishments. For some, there are chilling quotes by the killers themselves. The Big Book of Serial Killers is an easy-to-follow collection of information on the world's most heinous murderers.
