A Tale of the Batman: Gotham by Gaslight (1989)

Plot

In an age of mystery and superstition, how would the people of Gotham react to a weird creature of the night, a bat-garbed vigilante feared by the guilty and the innocent alike? Some would live in terror. Others would rest easier. Only one man would take no notice at all, a man with other matters to attend to. His name? No one knows for sure. Most people know him only as Jack. Jack the Ripper.
