From Jack Henry Abbott, who stabbed a waiter through the heart for not allowing him to use the toilet, to the "Zodiac," an unknown California serial killer who may have murdered as many as 37 people, this reference work details 280 of the most famous murder cases of the twentieth century. Each entry contains, when applicable, birth and death dates, aliases, occupation, location of the murders, weapons used, number of victims, and the time period when the killings occurred. Films, plays, television shows, videos and audio programs based on or inspired by the case are then cited, followed by a brief overview of the murder case and a bibliography of English-language works related to it.
