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.
