After a run-in with four notorious underworld gang leaders (one of whom is killed in the process), Lois decides to write a series of articles exposing them. When Lois is arrested for wearing a stolen mink coat from Lacey’s Department Store, Clark Kent learns that a former Lacey’s employee sold it to her.

A vicious criminal uses innocent people, trapped by hypnotic power, who are armed with a bomb apparatus that makes it possible for them to rob without opposition from the police. Superman must solve a series of bold crimes that were pulled by ungainly men who look anything but formidable. Lex Luthor survives his execution in the electric chair, which only makes him more powerful.

Whatever Happened to the Man of Tomorrow?" begins the final story of the Silver Age Superman, as written by legendary scribe Alan Moore. Superman's villains attack, revealing his secret identity to those closest to him! Continued in ACTION COMICS #583.
