I am reading a book titled "Eliot Ness and the Mad Butcher."
It is a true story and it takes place in Cleveland back in the 30's.
It so happens that Cleveland in the 20's was noted as a Dark city. Run by racketeers, mobsters, a corrupt police force, and bought politicians.
A tailor shop was owned by Mitchell Siegel. The shop was robbed and Mr. Siegel died of a heart attack while trying to stop the robbery.
His young son Jerry Siegel was devastated. He dreamt of a hero who would be invulnerable to bullets and would fight crime.
He met an artist named Joe Shuster and they created Superman.
The book is really interesting the Mad Butcher was one of the first recognized "serial killers."
