Ripperology is defined as being the study of the infamous serial killer Jack the
Ripper. Though the term has not made its way into the mainstream, those who study the
case, or are simply enthusiasts are referred to as 'Ripperologists'.
This does not simply refer to finding out who the killer was, but who all of the victims were, along with various "evidence" such as the highly debated credibility of the
Ripper letters.
