Cluemaster

Arthur Brown was a failed game-show host whose obsessive need to leave clues at his crimes — a compulsion he couldn't suppress — drove him to become the Gotham villain Cluemaster, pitting his tactical cunning against Batman.

A Silver Age creation who first stepped into the spotlight in Detective Comics #351 back in 1966, Cluemaster is one of DC's most enduringly intriguing figures — born from the imaginations of Jack Schiff and Sheldon Moldoff during one of comics' most inventive eras. Across a remarkable six decades of publication, this villain has kept some of the most legendary company in the DCU, sharing pages with Batman, Bruce Wayne, Robin, and Tim Drake across the pages of Detective Comics, Batman, and Robin. With four key-issue appearances flagged by collectors and a presence stretching all the way to 2026, Cluemaster is far more than a footnote — he's a persistent thread woven through the fabric of Gotham's rogue history. If you're building a serious Batman villain collection, this is one you'll want to track down.
