storyline The Cluemaster approached Wiley Cutter's gang for a team-up. Their first score together went down without a hitch, while Batman and Robin dealt with a hostage situation across town. Cluemaster insisted that he'd given up his shtick of leaving clues intentionally at the scene. A female in purple staked  out the Cluemaster's gang, and a clue was mailed to Gordon. Batman and Robin questioned Arthur Brown (the Cluemaster). Back at their hideout, Brown killed Cutter and took the gang for his own.
