There are many cultural myths about serial killers, often propagated even by mental health professionals. Many assume there is a "profile" of a serial killer, that serial killers always go for the same victim type or always use the same MO, that they are more clever than ordinary people, and that they are inevitably charming and attractive. The truth is not as simple as that. There are different types of serial killers, and while there are many books that discuss the serial killer phenomenon especially in relationship to victim types or context, researchers have not yet been able to come up with a definition, or type, that covers the broad spectrum of serial killers and their complex psychological dynamics. Ramsland looks at the variety of serial killer types, illustrating that it is difficult to accurately depict these elusive, intriguing, and dangerous killers.
