Batman (Easy readers)

When the Riddler kidnaps the son of a police detective, Batman comes to the rescue.

"What would the Gotham City of one hundred years ago have been like? 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. No one know for sure. Most people know him only as Jack. Jack the Ripper....

When the Joker escapes from Arkham Asylum, Batman tracks him to an amusement park and tries to stop him from stealing a valuable gem.
