"Riddle Me That, Part 5 of 5"
*Batman and the Riddler confront each other near the scroll of Minos in a Gotham City museum. Twists and turns abound, as Kara Harris turns on Batman, but he reveals that he knows she is actually Marie Harris, Kara's sister, and has been since he rescued her from the Riddler's trap. He also reveals that he has disabled the bomb, which Marie didn't know was real. Once Kara and Marie have been exchanged, the Riddler sets five cronies on Batman, but he is able to overcome them. The scroll of Minos retrieved, the Riddler deliberately sets off the security system and escapes under the closing door, leaving Batman and Kara trapped on the other side. But outside, the Riddler meets Martin Buttery, who has a score to settle with the Riddler, since the villain killed Martin's father. When Batman gets out of the museum, Martin hands the scroll back to him.
Later, Kara Harris decides not to write her story on Batman, particularly as it was the Riddler who arranged for her to get the job, simply to substitute Marie in her place. And Commissioner Akins discovers that the scroll handed to Batman was a fake. Elsewhere, the Riddler, Marie and Martin (who had no love for his father) make their getaway. The Riddler is pleased to have won this encounter, particularly as Batman cheated. *Source: DCUGuide.com
