All-American Comics #18

On the grounds of the World's Fair, Alan Scott meets Irene Miller when he stops her from shooting a man in cold blood. She explains that the man, Murdock, is a gang leader who framed her brother Danny for manslaughter when he tried to leave the gang. Investigating, Green Lantern discovers that Murdock framed Danny with the help of Judge Wake, an honest man forced to help when Murdock kidnapped his daughter. Green Lantern frees the girl and forces a confession out of Murdock before the gangster dies after falling off the Perisphere.
