This horrifyingly fascinating crime catalogue delves deep into the stories of some of the most cold-blooded murders of modern times. Anyone with even topical knowledge of these serial killers has asked "how could anyone do that'" Here, in a detailed exploration of the criminals' biography and psychology, an answer to that question is attempted, with an eye for insight into the workings of these sick minds. The infamous Los Angeles Hillside Strangler, Kenneth Bianchi, who strangled countless girls with his cousin Angelo, details his crimes firsthand, as do Ted Bundy and Henry Lee Lucas. The cases of the Lipstick Killer (William Heirens), The Broomstick Killer (Kenneth Allen McDuff), and Harv the Hammer (Harvey Louis Carginan), are all investigated. Also examined are lesser-known serial killers such as the Lethal Lovers, Catherine May Wood and Gwendolyn Graham, lesbian lovers who murdered patients in the nursing home where they worked to heighten their own pleasure.
