There is a template to Ripper writing. First, review all the available evidence and theories, then come up with your own suspect. “The main problem for all Ripperologists is that the contemporary evidence doesn’t provide any clue about the IDENTITY of the Ripper- and what remains of the evidence is scanty.” The Guardian.
Precisely, EXCEPT when H.H. Holmes is considered as the prime suspect. The evidence points directly at Hermann Webster Mudgett.
