Twelve killers, and their crimes, are profiled in this book in an attempt to gain some insight into how, and why, these defects of nature commit the horrible acts that have been attributed to them. Eleven of the subjects you will read about have been apprehended. One is still out there, his deeds going, as yet, unpunished. The details of the acts perpetrated by these savage killers are not for the faint of heart. They do, however, act as a reminder that evil really does walk among us.
