The World Encyclopedia of Serial Killers is the most comprehensive set of its kind in the history of true crime publishing. Written and compiled by Susan Hall, the four-volume set has more than 1600 entries of male and female serial killers from around the world.

Defined by the FBI as a person who murders 3 or more people over a period of time with a hiatus of weeks or months between murders, serial killers have walked among us from the dawn of time as these books will demonstrate. While the entries to these volumes will continue to grow—the FBI estimates that there are at least fifty serial killers operating in the United States at any given time—The World Encyclopedia of Serial Killers is as complete as possible through the end of 2017.

The series continues with Volume Four T-Z, plus the Unsolved Serial Killer Cases. The entries include the Terminator Anatoly Yuriyovych Onoprienko, Trailside Killer David Joseph Carpenter, Joseph Vacher, Vampire of Sacramento Richard Trenton Chase and the Voroshilovgrad Maniac Zaven Sarkisovich Almazyan, plus the Unsolved Serial Killer Cases of the Adelaide Child Murders, Axeman of New Orleans, Chillicothe Killer, Dead Women of Juarez, Korea Frog Boy Murders and Volga Maniac. You will find these killers and approximately 175 others plus approximately 225 Unsolved Serial Killer cases in this fourth book in the series of The World Encyclopedia of Serial Killers.
