Synopsis:
A thief with strange powers draws the attention of detective John Jones. John questions witnesses and believes the thief is a magician using illusions to fake his powers. John uses his own powers to track down the thief, which he learns is a martian criminal, who has landed on Earth after an exile in space. The crook has a belt, designed to keep him in space, which J'onn could use to return home. However, J'onn decides to use the belt to send the crook back into exile. He did not want to leave Earth unprotected from the martian criminal.
