Science Fiction Solves the Mystery of Jack the Ripper - io9

In Mike Resnick's "Red Chapel" (2001) which I read just before seeing the film made in Prague, with the famous cast about the "Ripper" that is "From Hell" (2001) he has it solved in fiction, with the assistance of the New York City Chief of Police at the time, Theodore Roosevelt, who would later become US Vice President then President after the assassination attempt that led to the death of then President William McKinley, shot at the Pan American Exposition in Buffalo, NY.
We saw "From Hell" while archaeology testing for new floodplain in Hurricane Floyd (1999) flooded Manville and Bridgewater, NJ and other damages at the West Point Military Academy during anthrax mails. I later saw in the same Reading Railroad theater, though empty, "Spy Game" (2001).
The character "Brig. General Jack D. Ripper" played by former OAS agent and actor, Sterling Hayden, in "Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb" (1964) directed by Stanley Kubrick, launched the preemptive aerial nuclear attack on the USSR before committing suicide.
