Superman en Batman #4/1967

In "De raadselachtige roverijen van de Raadselman!", the Riddler's latest escape from prison sets off a tense game of wits as he vows to stop sending riddles before his crimes—yet Batman, ever sharp, picks up on subtle clues that hint at a pattern only he can unravel. Written by Gardner Fox and brought to life by Sheldon Moldoff’s expressive art and Joe Giella’s crisp inks, this 1967 classic delivers a clever, suspenseful showdown between detective and criminal mind.
