Author and Lewis Carroll scholar Richard Wallace put out a book
called Jack the Ripper’s Light-Hearted Friend that proposes that Lewis Carroll
could have been Jack the Ripper.
Although Carroll was widely known as a gentle soul and
scholar-Mathematician, Wallace says that Carol had a nervous breakdown and as a
result developed a separate persona as Jack the ripper, Carroll’s psychotic
breakdown had come from years of abuse that he took from older boys at school
and that he took his vengeance on prostitutes.
