Batman: Gotham by Gaslight

In Victorian-era Gotham City, Bruce Wayne is operating as the bat-garbed vigilante, the Batman, who is feared by the guilty and the innocent alike. One night, Batman saves a wealthy couple from being robbed by three orphans (Dickie, Jason and Timmy) and defeats their abusive handler, Big Bill Dust. At the same time, Ivy, an orphan turned exotic dancer and prostitute, becomes the newest victim of the serial killer called Jack the Ripper, who preys on Gotham's poor and destitute women.
