This book is a work of fiction, and I do not know of any other killer who is this evil and monstrous. You would have to go back to the late 1800s when such maniacal killers existed. One name that comes to mind would be the unsolved mysteries of Jack the Ripper, who killed prostitutes. Another great mystery was written by Robert Louis Stevenson, and that novel was called The Strange Case of Dr. Jekyll and Mr. Hyde, which dealt with the problems of a split personality. Here, I mean no harm to those that bear similar names to the criminals within my novel. I argue that such is purely coincidental and a result of both probability and chance.
