The hour of the bat. The Riddler has always been an above-average criminal, but he's never managed to outwit the world's greatest detective. With his latest caper, however, something has changed -- the clever, exuberant Edward Nigma has turned vicious and bloodthirsty. Leaving bodies strewn in his wake, this new menace kidnaps four innocent babies and leads Batman through a labyrinth of grim trials to rescue them. What purpose could he have for such cruelty? As the Dark Knigh is about to find out, the Riddler has discovered a dark secret trapped beneath the city's streets -- an unearthly entity brought into the world centuries agho that threatens to destroy both villain and hero.
