Sometimes it can manifest as the desire to dominate the weak and the less fortunate; in others, it becomes an uncontrollable need for violence and death; another group turns this evil into pure hatred for those that they do not agree with, transforming dislike into the desire to spill blood.

Regardless of which group we are talking about, there are many of these individuals who soon evolve into the most deadly kind of monster: the serial killer.

In the following volumes, you shall discover the stories of six murderers so tainted by darkness that their horrific accounts still bring fear to men and women of our present day:

• Edmund Kemper, the Co-Ed Killer, whose victims were mostly young, defenseless students.
• The Briley Brothers, three siblings who were as mentally unstable as they were bloodthirsty.
• Christopher Wilder, serial killer who mercilessly killed in two different continents.
• John Christie, who lived a double life while killing cruelly and indiscriminately.
• John Haigh or The Acid Bath Murderer, whose methods of disposing of victims made him infamous.
• Joseph Paul Franklin, whose racist hatred fueled him into a deadly "cleansing of the world," according to his own claims.
