Dr. Byron Merideth was not well-liked during his tenure at Arkham Asylum. To the relief of many of his coworkers who disapproved of his practices, he quit, and began a private practice meant to deal exclusively with those who had Joker-related obsessive disorders. Yesterday, Merideth's charred remains were discovered, identifiable only by his dental records. The arsonists called themselves the League of Smiles, and they were all patients of Merideth's. Only one member of the league remains unidentified by the Batman, their leader: Merrymaker.
